Modulation of defense genes and phenolic compounds in wild blueberry in response to Botrytis cinerea under field conditions.

Botrytis blight is an important disease of wild blueberry [(Vaccinium angustifolium (Va) and V. myrtilloides (Vm))] with variable symptoms in the field due to differences in susceptibility among blueberry phenotypes. Representative blueberry plants of varying phenotypes were inoculated with spores of B. cinerea. The relative expression of pathogenesis-related genes (PR3, PR4), flavonoid biosynthesis genes, and estimation of the concentration of ten phenolic compounds between uninoculated and inoculated samples at different time points were analyzed. Representative plants of six phenotypes (brown stem Va, green stem Va, Va f. nigrum, tall, medium, and short stems of Vm) were collected and studied using qRT-PCR. The expression of targeted genes indicated a response of inoculated plants to B. cinerea at either 12, 24, 48 or 96 h post inoculation (hpi). The maximum expression of PR3 occurred at 24 hpi in all the phenotypes except Va f. nigrum and tall stem Vm. Maximum expression of both PR genes occurred at 12 hpi in Va f. nigrum. Chalcone synthase, flavonol synthase and anthocyanin synthase were suppressed at 12 hpi followed by an upregulation at 24 hpi. The expression of flavonoid pathway genes was phenotype-specific with their regulation patterns showing temporal differences among the phenotypes. Phenolic compound accumulation was temporally regulated at different post-inoculation time points. M-coumaric acid and kaempferol-3-glucoside are the compounds that were increased with B. cinerea inoculation. Results from this study suggest that the expression of PR and flavonoid genes, and the accumulation of phenolic compounds associated with B. cinerea infection could be phenotype specific. This study may provide a starting point for understanding and determining the mechanisms governing the wild blueberry-B. cinerea pathosystem.

Multi-drug resistant bacteria isolates from lymphatic filariasis patients in the Ahanta West District, Ghana.

BACKGROUND: Antimicrobial resistance is associated with increased morbidity in secondary infections and is a global threat owning to the ubiquitous nature of resistance genes in the environment. Recent estimate put the deaths associated with bacterial antimicrobial resistance in 2019 at 4.95 million worldwide. Lymphatic filariasis (LF), a Neglected Tropical Disease (NTD), is associated with the poor living in the tropical regions of the world. LF patients are prone to developing acute dermatolymphangioadenitis (ADLA), a condition that puts them at risk of developing secondary bacterial infections due to skin peeling. ADLA particularly worsens the prognosis of patients leading to usage of antibiotics as a therapeutic intervention. This may result in inappropriate usage of antibiotics due to self-medication and non-compliance; exacerbating antimicrobial resistance in LF patients. In this perspective, we assessed the possibilities of antimicrobial resistance in LF patients. We focused on antibiotic usage, antibiotic resistance in Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa isolates and looked at genes (mecA and Extended-spectrum beta-lactamase [blaCTX-M, blaSHV and blaTEM]) coding for resistance in multi-drug resistant (MDR) bacterial isolates. RESULTS: Of the sixty (60) participants, fifty-four (n = 54, 90%) were within 31-60 years of age, twenty (n = 20, 33.33%) were unemployed and thirty-eight (n = 38, 50.67%) had wounds aged (in months) seven (7) months and above. Amoxicillin (54%) and chloramphenicol (22%) were the most frequently used antibiotics for self-medication. Staphylococcus aureus isolates (n = 26) were mostly resistant to penicillin (n = 23, 88.46%) and least resistant to erythromycin (n = 2, 7.69%). Escherichia coli isolates (n = 5) were resistant to tetracycline (n = 5, 100%) and ampicillin (n = 5, 100%) but were sensitive to meropenem (n = 5, 100%). Pseudomonas aeruginosa isolates (n = 8) were most resistant to meropenem (n = 3, 37.50%) and to a lesser ciprofloxacin (n = 2, 25%), gentamicin (n = 2, 25%) and ceftazidime (n = 2, 25%). Multi-drug resistant methicillin resistant Staphylococcus aureus (MRSA), cephalosporin resistant Escherichia coli. and carbapenem resistant Pseudomonas aeruginosa were four (n = 4, 15.38%), two (n = 2, 40%) and two (n = 2, 25%) respectively. ESBL (blaCTX-M) and mecA genes were implicated in the resistance mechanism of Escherichia coli and MRSA, respectively. CONCLUSION: The findings show presence of MDR isolates from LF patients presenting with chronic wounds; thus, the need to prioritize resistance of MDR bacteria into treatment strategies optimizing morbidity management protocols. This could guide antibiotic selection for treating LF patients presenting with ADLA.

Challenges with adherence to the 'test, treat, and track' malaria case management guideline among prescribers in Ghana.

BACKGROUND: Despite several efforts at addressing the barriers to adherence to the WHO-supported test, treat and track (T3) malaria case management guideline in Ghana, adherence remains a challenge. This study explored the challenges of prescribers regarding adherence to the T3 guideline. METHODS: This was an explorative study using key informant interviews amongst prescribers comprising medical doctors, physician assistants, nurses and a health extension worker from 16 health facilities in six districts in Ghana. The data was analysed using Nvivo 10 and organized into thematic areas. RESULTS: Prescribers lauded the guideline on testing and treatment as it ensures the quality of malaria case management, but irregular supply of malaria rapid diagnostic test kits (RDT), mistrust of laboratory tests, and the reluctance of prescribers to change from presumptive treatment were key barriers to testing. Patients with malaria test negative results if not treated, revisiting the facility with severe malaria, the experience of prescribers, lack of regular training and supervision for old and new staff and the inability of prescribers to investigate non-malaria fever hindered adherence to results-based treatment. CONCLUSION: As malaria remains a significant cause of morbidity and mortality in Ghana, this study provides insights on gaps in adherence to the testing and treatment of malaria. While the diagnostic capacity for malaria case management is a challenge, the lack of training resulting in the inability of some prescribers to investigate non-malaria fever hinders adherence to the malaria case management guideline. Therefore, there is a need to train new prescribers, laboratory personnel, and other staff involved in malaria diagnosis and treatment on the malaria case management guideline before they assume duty. Equipping laboratory personnel and prescribers with the knowledge to investigate non-malaria fevers could improve adherence to the guideline for improved patient care.

Incremental cost and cost-effectiveness of the addition of indoor residual spraying with pirimiphos-methyl in sub-Saharan Africa versus standard malaria control: results of data collection and analysis in the Next Generation Indoor Residual Sprays (NgenIRS) project, an economic-evaluation.

BACKGROUND: Malaria is a major cause of morbidity and mortality globally, especially in sub-Saharan Africa. Widespread resistance to pyrethroids threatens the gains achieved by vector control. To counter resistance to pyrethroids, third-generation indoor residual spraying (3GIRS) products have been developed. This study details the results of a multi-country cost and cost-effectiveness analysis of indoor residual spraying (IRS) programmes using Actellic®300CS, a 3GIRS product with pirimiphos-methyl, in sub-Saharan Africa in 2017 added to standard malaria control interventions including insecticide-treated bed nets versus standard malaria control interventions alone. METHODS: An economic evaluation of 3GIRS using Actellic®300CS in a broad range of sub-Saharan African settings was conducted using a variety of primary data collection and evidence synthesis methods. Four IRS programmes in Ghana, Mali, Uganda, and Zambia were included in the effectiveness analysis. Cost data come from six IRS programmes: one in each of the four countries where effect was measured plus Mozambique and a separate programme conducted by AngloGold Ashanti Malaria Control in Ghana. Financial and economic costs were quantified and valued. The main indicator for the cost was cost per person targeted. Country-specific case incidence rate ratios (IRRs), estimated by comparing IRS study districts to adjacent non-IRS study districts or facilities, were used to calculate cases averted in each study area. A deterministic analysis and sensitivity analysis were conducted in each of the four countries for which effectiveness evaluations were available. Probabilistic sensitivity analysis was used to generate plausibility bounds around the incremental cost-effectiveness ratio estimates for adding IRS to other standard interventions in each study setting as well as jointly utilizing data on effect and cost across all settings. RESULTS: Overall, IRRs from each country indicated that adding IRS with Actellic®300CS to the local standard intervention package was protective compared to the standard intervention package alone (IRR 0.67, [95% CI 0.50-0.91]). Results indicate that Actellic®300CS is expected to be a cost-effective (> 60% probability of being cost-effective in all settings) or highly cost-effective intervention across a range of transmission settings in sub-Saharan Africa. DISCUSSION: Variations in the incremental costs and cost-effectiveness likely result from several sources including: variation in the sprayed wall surfaces and house size relative to household population, the underlying malaria burden in the communities sprayed, the effectiveness of 3GIRS in different settings, and insecticide price. Programmes should be aware that current recommendations to rotate can mean variation and uncertainty in budgets; programmes should consider this in their insecticide-resistance management strategies. CONCLUSIONS: The optimal combination of 3GIRS delivery with other malaria control interventions will be highly context specific. 3GIRS using Actellic®300CS is expected to deliver acceptable value for money in a broad range of sub-Saharan African malaria transmission settings.

Financial burden impact quality of life among lymphatic Filariasis patients.

BACKGROUND: Human lymphatic filarial pathology is the leading cause of disability and poverty among people living with the infection. The second goal of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) is to manage the disease's morbidity to improve patients' quality of life. Consequently, the current study assessed the overall quality of life of lymphatic filariasis (LF) pathology patients in some selected endemic communities in rural Ghana. METHOD: In the present study, the Lymphatic Filariasis Quality of Life Questionnaire (LFSQQ) was used to evaluate the effect of lymphatic filariasis on the quality of life of people, with the disease in nine (9) communities in the Ahanta West District of the Western Region of Ghana where mass drug administration is being implemented for the past twenty years. Pearson's correlation, linear regression, and one-way analysis of variance (ANOVA) analyses were used to assess the associations between the LFSQQ instrument domains. RESULTS: Of the 155 study participants recruited, 115 (74.19%) were females, and 40 (25.81%) males. A greater proportion of the study participants (40, 25.8%) were presented with stage two (2) lymphoedema, while only two patients had stage seven (7) lymphoedema. The average of the overall quality of life scores of study participants was 68.24. There was a negative Pearson correlation (r = - 0.504, p-value < 0.001) between the stage of lymphoedema (severity of the disease) and the quality of life of the LF patients. In addition, a clear pattern of positive correlation (r = 0.71, p-value < 0.001) was observed between the disease burden and pain/discomfort domains of the study participants. Whereas the highest domain-specific score (85.03) was observed in the domain of self-care, we noted that the environmental domain, which consists of the financial status, was the lowest (45.94) among the study participants. CONCLUSION: Our findings support previous works on the reduced quality of life among lymphatic filariasis patients with pathology. In this study, our results reveal a depressing financial condition among people presenting with late stages of LF pathologies, which eventually reduces their well-being.

An observational analysis of the impact of indoor residual spraying in Northern, Upper East, and Upper West Regions of Ghana: 2014 through 2017.

BACKGROUND: Ghana has been implementing the indoor residual spraying (IRS) of insecticides since 2006, focusing operations in the north. Insecticide resistance concerns prompted a switch from pyrethroids to organophosphates, beginning gradually in 2011 and switching fully to the micro-encapsulated formulation of pirimiphosmethyl (PM CS), Actellic® 300CS, a third-generation indoor residual spraying (3GIRS) product, by 2014. Entomological surveillance studies have shown IRS to be a highly effective malaria control tool, but epidemiological evidence is needed as well. Countrywide prevalence surveys have shown that malaria parasite prevalence in children under 5 years of age in Northern, Upper East, and Upper West Regions had declined to less than 40% in each region by 2016. Similarly, malaria deaths in children under 5 years of age have also been declining nationally since 2009. Although IRS is suspected to have contributed to this decline, stronger evidence is needed to link the IRS interventions to the epidemiological impact. METHODS: To assess the epidemiological impact of Ghana's IRS programmatic activities, a retrospective, observational analysis using routine epidemiological data was conducted to compare malaria incidence rates from IRS and non-IRS districts in Northern, Upper East, and Upper West Regions. Routine epidemiological data consisted of passive malaria case surveillance data reported in the District Health Information System 2 (DHIS2); with cases representing patients with suspected malaria who had sought care in the public health system and had received a confirmatory diagnosis with a positive malaria RDT result. Final routine data were extracted in September 2018. All districts that had received IRS were included in the analysis and compared to all non-IRS districts within the same region. In the Northern Region, only PMI districts were included in the analysis, as they had similar historical data. RESULTS: District-level analysis from Northern Region from 2015 to 2017 of the aggregate malaria incidence reported from IRS districts relative to non-IRS comparator districts showed 39%, 26%, and 58% fewer confirmed malaria cases reported from IRS districts in 2015, 2016, and 2017, respectively. This translates to approximately 257,000 fewer cases than expected over the three years. In Upper East Region, the effect on reported malaria cases of withdrawing IRS from the region was striking; after spray operations were suspended in 2015, incidence increased an average of 485% per district (95% confidence interval: 330% to 640%) compared to 2014. CONCLUSIONS: The current observational analysis results are in line with the entomological studies in demonstrating the positive contribution of IRS with a 3GIRS product to malaria control programmes in northern Ghana and the value of using routine surveillance and implementation data to rapidly assess the impact of vector control interventions in operational settings, even in complex implementation environments.

Every medicine is medicine; exploring inappropriate antibiotic use at the community level in rural Ghana.

BACKGROUND: Inappropriate antibiotic use is an important driver of antibiotic resistance. This study sought to explore inappropriate antibiotic use and confusing antibiotics with other medicines in Ghana using ethnomethodology research approach. METHODS: This was an explorative study involving 15 in-depth interviews among health professionals and private dispensers and eight focus group discussions among 55 community members. Qualitative data were coded using Nvivo 12, thematically analysed and presented as narratives with quotes to support the findings. RESULTS: Self-medication was common and antibiotics were used to treat specific diseases but respondents were not aware these were 'antibiotics'. Various antibiotics were used for indications that in principle do not require systemic antibiotics, like stomach ache and sores on the body. Antibiotics, in particular tetracycline and metronidazole, were poured into "akpeteshie" (local gin) to treat hernia and perceived stomach sores (stomach ulcer). These practices were copied/learnt from various sources like over-the-counter medicine sellers, family, friends, radio/television, drug peddlers, pharmacies and doctors. Medicines in capsules were referred to as 'topaye' or 'abombelt' in Twi (local dialect) and perceived to treat pain associated with diseases. Antibiotics in capsules were described with colours which appeared confusing as some capsules with different drugs in them have similar colours. CONCLUSION: Inappropriate antibiotic use were influenced by general lack of knowledge on antibiotics and identification of antibiotics by colours of capsules which leads to confusion and could lead to inappropriate antibiotic use. There is the need for public health education on appropriate antibiotic use and standardization of appearance of antibiotics and other drugs to optimize use.

Seeking treatment for uncomplicated malaria: experiences from the Kintampo districts of Ghana.

BACKGROUND: Malaria accounts for many deaths and illnesses, mostly among young children and pregnant women in sub-Saharan Africa. An integrated approach is recommended to ensure effective malaria control. Socio-cultural factors continue to serve as determinants of malaria health-seeking behaviour. An INDEPTH effectiveness and safety study platform was established to unearth issues around the use of licensed and nationally recommended anti-malarials in real life settings. This study reports on treatment-seeking behaviour for uncomplicated malaria among community members. METHODS: A qualitative study was conducted in the dry and rainy seasons in purposively selected communities in Kintampo north and south districts. This was based on distances to a health facility, ethnicity and availability of medicines at the sale outlets. Twenty-four focus group discussions were conducted among adult men, women care-takers of children less than 5 years and pregnant women. Ten INDEPTH interviews were also conducted among operators of medicine sale outlets and managers of health facilities. Fifty-one illnesses narrative interviews were conducted among adult men, women, women caretakers of children less than 5 years and pregnant women. Transcripts were transferred into Nvivo 8 software for data management and analysis. RESULTS: The artemisinin-based combinations that were commonly known and used were artesunate-amodiaquine and artemether-lumefantrine. Use of herbal preparation to treat diseases including uncomplicated malaria is rife in the communities. Drug stores were not the main source of artemisinin-based combination sales at time of the study. Monotherapies, pain killers and other medicines were purchased from these shops for malaria treatment. Dizziness, general body weakness and sleepiness were noted among respondents who used artemisinin-based combination therapy (ACT) in the past. CONCLUSION: There is no clear cut trajectory for management of uncomplicated malaria in the study area. Different approaches are adopted when treating malaria. There is need for community education to influence behaviour on the management of malaria to achieve real gains from ACT use.

Boosting resistant starch in rice: Bacterial inulin as a metabolic and glucose uptake modulator.

Bacillus stercoris PSSR12 (B. stercoris PE), an isolate from rice field soils, was identified via 16s rRNA sequencing. The synthesis of the inulin and inulin producing enzyme (IPE) in B. stercoris PE was verified using SDS-PAGE and FTIR. This study aimed to assess the impact of B. stercoris PE treatment on in vitro inhibition of α-amylase and α-glucosidase from traditional and commercial rice varieties of South India. Additionally, the study investigated enzymatic inhibition and mRNA expression of starch synthesis genes (RAmy1a, GBSSIa, SBEIIa, and SBEIIb). Glucose transporter gene expression (GLUT1 and GLUT4) patterns were analyzed in 3T3-L1 adipocytes to evaluate glucose uptake in B. stercoris PE treated rice varieties. The application of B. stercoris PE enhanced grain quality by imparting starch ultra-structural rigidity, inhibiting starch metabolizing enzymes, and inducing molecular changes in starch synthesis genes. This approach holds promise for managing type II diabetes mellitus and potentially reducing insulin dependence.

Liposome-encapsulated cytochrome P450 and gibberellic acid biosynthesis in Priestia megaterium RP1.

This study explores the potential of liposome encapsulated silica immobilized cytochrome P450 monooxygenase (LSICY) for bioremediation of mercury (Hg2+). Current limitations in Hg2+ reduction, including sensitivity to factors like pH and cost, necessitate alternative methods. We propose LSICY as a solution, leveraging the enzymatic activities of cytochrome P450 monooxygenase (CYPM) for Hg2+ reduction through hydroxylation and oxygenation. Our investigation employs LSICY to assess its efficacy in mitigating Hg2+ toxicity in Oryza sativa (rice) plants. Gas chromatography confirmed gibberellic acid (GA) presence in the Hg2+ reducing bacteria Priestia megaterium RP1 (PMRP1), highlighting a potential link between CYP450 activity and plant health. This study demonstrates the promise of LSICY as a sustainable and effective approach for Hg2+ bioremediation, promoting a safer soil environment.

Impact of the COVID-19 pandemic on handwashing practices among community members in the middle belt of Ghana: evidence from a cross-sectional study.

Handwashing is an effective public health intervention for preventing the spread of coronavirus (COVID-19). Maintenance of clean hands is particularly important during the pandemic, to break the cycle of human-to-human transmission of the virus. This study explored the potential impact of the COVID-19 pandemic on the handwashing behaviours of residents before and during the pandemic. A mixed-method cross-sectional design using standardised questionnaire was used to examine hand handwashing behaviours among residents before and during the COVID-19 pandemic in the middle belt of Ghana. However, this paper reports on the quantitative data on handwashing behaviour only. A total of 517 participants between 18 to 60 years were randomly selected from the Kintampo Health and Demographic Surveillance System (HDSS) database. Descriptive statistics were performed and McNamar test was used to estimate the difference in the handwashing behaviour of residents. Majority of the respondents were females (54.6%). The majority of them 77.0% (398) usually wash their hands with soap and water. Those who washed hands 4 to 6 times a day before the pandemic increased from 39.9% (159) to 43.7% (174). About 34.8% (180) had received training on hand washing and television 53.3% (96) emerged as the main source of training. Ownership of handwashing facilities increased from 11.4% (59) to 22.8% (118) during the pandemic. The odds of handwashing after handshaking were lower 0.64 (95% C1: 0.44-0.92,) during the pandemic. Television (53.3%) was the main source of training for respondents who had received training on handwashing (34.8%). The odds of owning a handwashing facility during the pandemic were 3 times higher than before (OR = 2.97, 95% CI: 1.94 - 4.65). The odds of handwashing after sneezing were 1.8 (95% CI: 1.19-2.92) times higher during the pandemic. Handwashing behaviours during the pandemic improved among residents than before. However, there is a need to intensify health education and media engagement on proper handwashing practices to protect the population against infectious diseases.

Knowledge and perceptions of lymphatic filariasis patients in selected hotspot endemic communities in southern Ghana.

Lymphatic filariasis (LF) is a mosquito-borne neglected tropical disease that is one of the leading global causes of permanent disability. To date, LF interventions have been largely biomedical, focusing on drug treatments to disrupt parasite transmission and manage disease morbidity. Although important, these Mass Drug Administration (MDA) programs neglect the significance of socio-economic burden to the health of LF patients, which are compounded by social stigmatization, discrimination and associated depressive illnesses. The MDA program also typically fails to engage with local community beliefs and perceptions of LF, which may differ markedly from biomedical explanations and may have fueled non-compliance to treatments which is one of the major challenges of the Mass Drug Administration program. LF is not only a biomedical issue but also a social issue and LF interventions need to understand people's world views and the contexts through which they interpret bodily maladies. Hence, an effective LF intervention must bring together both the biomedical and the social components. The goal of this exploratory study was to assist in refining a large qualitative study (currently underway) that seeks to integrate culturally appropriate LF interventions into current LF control programs in Ghana. In this paper, we discuss the findings of a pre-intervention, exploratory study aimed at gaining a baseline grasp of a local culturally informed understanding of lymphatic filariasis and the knowledge gaps looking at three endemic Ghanaian communities in the Ahanta West District. A structured questionnaire was employed to assess the wellbeing, social inclusion, and cultural understanding of LF with a geographic focus within LF-endemic areas in Ghana. Interestingly, 45.8% of the 72 participants reported to have received information about LF from health care providers and the MDA program but only 5 out of the 72 (6.9%) respondents believed that LF was transmitted by mosquitos. This baseline study revealed several alternative interpretations and misconceptions about the disease, as well as the social and economic impacts, and importantly, the need to integrate qualitative research to develop culturally appropriate interventions and increase engagement with existing control programs.

Myeloid- and epithelial-derived RELMα contribute to tissue repair following lung helminth infection.

Soil-transmitted helminth (STH) infections impact billions of individuals globally; however, there is a need to clarify the long-term impacts of these infections on pulmonary health owing to their transient migration and subsequent damage to the lungs. In mouse models of these infections using Nippostrongylus brasiliensis, lung pathology persists at later time points post single infection. These studies also indicate the persistent transcriptional expression of resistin-like molecule α (RELMα), an immunomodulatory protein induced in type 2 immunity and alternatively activated macrophages. Using constitutive and tamoxifen-inducible cell-specific RELMα knockout mouse strains, we identified that epithelial- and myeloid-derived RELMα protein remained elevated at 30 days post infection and altered the immune cell signature and gene expression in lung compartments. Histopathological assessment of alveolar damage revealed a role for RELMα in tissue repair, suggesting the importance of sustained RELMα expression for lung recovery from helminth infection. Acellular three-dimensional (3D) lung scaffolds were prepared from the lungs of wild-type (WT), RELMα KO-naive, or 30 days post N. brasiliensis-infected mice to assess their ability to support epithelial cell growth. N. brasiliensis infection significantly altered the scaffold and impaired epithelial cell growth and metabolic activity, especially in the RELMα KO scaffolds. These findings underscore a need to identify the long-term impacts of helminth infection on human pulmonary disease, particularly as alveolar destruction can develop into chronic obstructive pulmonary disease (COPD), which remains among the top global causes of death. Translation of these findings to human protein resistin, with sequence homology to RELMα therapeutic opportunities in lung repair.

Antibiotic resistance and mecA characterization of Staphylococcus hominis from filarial lymphedema patients in the Ahanta West District, Ghana: A cross-sectional study.

Background and Aim: Filarial infections affect over 150 million people in the tropics. One of the major forms of filarial pathologies is lymphedema; a condition where the immune response is significantly altered, resulting in changes in the normal flora. Staphylococcus hominis, a human skin commensal, can also be pathogenic in immunocompromised individuals. Therefore, there is the possibility that S. hominis could assume a different behavior in filarial lymphedema patients. To this end, we investigated the levels of antibiotic resistance and extent of mecA gene carriage in S. hominis among individuals presenting with filarial lymphedema in rural Ghana. Method: We recruited 160 individuals with stages I-VII lymphedema, in a cross-sectional study in the Ahanta West District of the Western Region of Ghana. Swabs from lymphedematous limb ulcers, pus, and cutaneous surfaces were cultured using standard culture-based techniques. The culture isolates were subjected to Matrix-Assisted Laser Desorption/Ionization Time of Flight (MALDI-TOF) mass spectrometry for bacterial identification. Antimicrobial susceptibility testing (AST) was performed using the Kirby-Bauer method. mecA genes were targeted by polymerase chain reaction for strains that were cefoxitin resistant. Results: In all, 112 S. hominis were isolated. The AST results showed resistance to chloramphenicol (87.5%), tetracycline (83.3%), penicillin (79.2%), and trimethoprim/sulphamethoxazole (45.8%). Of the 112 strains of S. hominis, 51 (45.5%) were resistant to cefoxitin, and 37 (72.5%) of the cefoxitin-resistant S. hominis haboured the mecA gene. Conclusion: This study indicates a heightened level of methicillin-resistant S. hominis isolated among filarial lymphedema patients. As a result, opportunistic infections of S. hominis among the already burdened filarial lymphedema patients in rural Ghana may have reduced treatment success with antibiotics.

Quality of Data Recording and Antimicrobial Use in a Municipal Veterinary Clinic in Ghana.

The recording of antimicrobial use data is critical for the development of interventions for the containment of antimicrobial resistance. This cross-sectional study assessed whether dissemination activities and recommendations made after an operational research (OR) study in 2021 resulted in better data recording and improved the use of antimicrobials in a rural veterinary clinic. Routinely collected data from treatment record books were compared between 2013 and 2019 (pre-OR) and from July 2021 to April 2023 (post-OR). The most common animals presenting for care in the the pre - and post OR periods were dogs (369 and 206, respectively). Overall, antimicrobial use in animals increased from 53% to 77% between the two periods. Tetracycline was the most commonly used antimicrobial (99%) during the pre-OR period, while Penicillin-Streptomycin was the most commonly used antimicrobial (65%) during the post-OR period. All animals that received care at the clinic were documented in the register during both periods. Whereas the diagnosis was documented in 269 (90%) animals in the post-OR period compared to 242 (47%) in the pre-OR period, the routes and dosages were not adequately recorded during the both periods. Therefore, the quality of data recording was still deficient despite the dissemination and the recommendations made to some key stakeholders. Recommendations are made for a standardized antimicrobial reporting tool, refresher training, and continuous supervisory visits to the clinic.

"I don't want to have anything to do with someone suspected of COVID-19": a genuine infection avoidance interest or inappropriate concerns related to stigma?

Background: Human existence is being challenged by an outbreak of coronavirus disease 2019 (COVID-19) caused by the virus SARS-CoV-2 that began in Wuhan, China in December 2019. Efforts to avoid the spread of COVID-19 are undermined by the appearance of disease-associated avoidance of infected persons due to reasons such as social stigma and discrimination. Objective: This study seeks to investigate avoidance and discrimination against persons suspected of COVID-19 to help fight the pandemic in a predominantly rural setting in Ghana. Materials and Methods: The study is a cross sectional survey. A random sample of 517 individuals drawn from a health and demographic surveillance system database was used for this study. Participants resided in six contiguous districts and municipalities of predominantly rural setting in the Bono East Region of Ghana. Results: The findings showed that majority (60%) of the respondents agreed that they won't have anything to do with someone suspected of COVID-19. However, 67% of them were willing to accommodate persons that recovered from the infection. The majority (91%) of respondents agreed that there is a need to adopt tolerant attitude towards persons who recovered from the infection, whilst another 98% also reported the need to show compassion towards persons who recovered from COVID-19. Conclusions: There is the need to pay special attention to avoidance of suspected infected persons due to stigma or any other reason since it is a threat to the fight against the pandemic.

Is this pill an antibiotic or a painkiller? Improving the identification of oral antibiotics for better use.

In this Viewpoint, we discuss how the identification of oral antibiotics and their distinction from other commonly used medicines can be challenging for consumers, suppliers, and health-care professionals. There is a large variation in the names that people use to refer to antibiotics and these often relate to their physical appearance, although antibiotics come in many different physical presentations. We also reflect on how the physical appearance of medicine influences health care and public health by affecting communication between patients and health-care professionals, dispensing , medicine use, and the public understanding of health campaigns. Furthermore, we report expert and stakeholder consultations on improving the identification of oral antibiotics and discuss next steps towards a new identification system for antibiotics. We propose to use the physical appearance as a tool to support and nudge awareness about antibiotics and their responsible use.

An assessment of the likely acceptability of vaginal microbicides for HIV prevention among women in rural Ghana.

BACKGROUND: The findings of the CAPRISA tenofovir studies have raised expectations that soon an approved microbicide would be available. However it is in only a limited number of countries in sub-Saharan Africa that the acceptability of microbicides has been evaluated. We conducted a study to assess the acceptability of vaginal microbicides among women in rural Ghana. METHODS: The study employs a mixed method design, using cross-sectional survey and focus group discussions to further understand issues related to awareness and attitudes towards microbicide development, acceptability and perceived partner attitudes among pregnant women attending antenatal clinic in two health facilities in the Kintampo North municipality of Ghana. We used logistic regression to identify possible predictors of microbicide acceptability among the women surveyed. RESULTS: Although only 2% of the 504 women were aware of the development of microbicides, 95% were willing to use one when it became available. The cost of a microbicide that will be considered affordable to 50% of women was US$0.75. Although there were concerns about possible wetting effect, gel or creams were the most preferred (68% of women) formulation. Although 71% thought their partners will find microbicide acceptable, apprehensions about the feasibility of and consequences of failed discreet use were evident. 49% of women were concerned about possible negative effect of microbicide on sexual pleasure. Perceived partner acceptability (O.R. =17.7; 95%C.I. 5.03-62.5) and possibility of discreet use (O.R. =8.9 95%C.I. 2.63-30.13) were the important predictors of microbicide acceptability. CONCLUSION: Achieving microbicide acceptability among male partners should be made a part of the promotive interventions for ensuring effective use among women in rural Ghana.

Aluminum in plant: Benefits, toxicity and tolerance mechanisms.

Aluminum (Al) is the third most ubiquitous metal in the earth's crust. A decrease in soil pH below 5 increases its solubility and availability. However, its impact on plants depends largely on concentration, exposure time, plant species, developmental age, and growing conditions. Although Al can be beneficial to plants by stimulating growth and mitigating biotic and abiotic stresses, it remains unknown how Al mediates these effects since its biological significance in cellular systems is still unidentified. Al is considered a major limiting factor restricting plant growth and productivity in acidic soils. It instigates a series of phytotoxic symptoms in several Al-sensitive crops with inhibition of root growth and restriction of water and nutrient uptake as the obvious symptoms. This review explores advances in Al benefits, toxicity and tolerance mechanisms employed by plants on acidic soils. These insights will provide directions and future prospects for potential crop improvement.
