RESUMEN
BACKGROUND: Concurrent infections or co-infections caused by intestinal parasites and Helicobacter pylori are quite rampant in paediatrics living in endemic areas of sub-Saharan Africa, including Ethiopia, and if left untreated, can result in severe complications and hence must be addressed to ensure their health and well-being. OBJECTIVES: To determine the prevalence of intestinal parasitic and H. pylori co-infections and associated factors among paediatric patients with gastrointestinal symptoms who attended the Arba Minch General Hospital (AMGH), Arba Minch, southern Ethiopia, from September to November 2020. METHODS: A cross-sectional study was conducted among a study population of 299 paediatric patients with gastrointestinal symptoms who visited AMGH. Stool samples were collected and analysed to detect H. pylori and intestinal parasites. A rapid lateral flow chromatographic immunoassay was employed to identify the H. pylori copra antigen, whereas the latter was detected using wet mount saline preparation and formol-ether concentration method. Socio-demographic, clinical, behavioural and other factors were obtained by means of a pre-tested structured questionnaire. Descriptive statistics and logistic regression analysis were done by Statistical Package for Social Service (SPSS) version 25; P values < 0.05 were considered statistically significant. RESULTS: The prevalence of Helicobacter pylori and intestinal parasites was 14% (n = 42) and 37.1% (n = 111), respectively, whereas that of the co-infections with these pathogens was 6.4% (n = 19). Giardia lamblia was the most prevailing parasite, 21.4% (n = 64). Informal maternal education [AOR = 5.14; 95% CI: 1.98-15.70] and lack of hand washing practice were significantly associated with the extent of co-infections [AOR = 4.18; 95% CI: 1.36-12.80]. CONCLUSION: Nearly one in twenty pediatric patients with gastrointestinal symptoms had intestinal parasitic infections and H. pylori co-infections, representing a silent health problem that is to be addressed through effective control strategies. Health administrators should consider the importance of co-infections in clinical diagnosis and planning aimed at its prevention.

BACKGROUND: Typical pneumonia is a pressing issue in the treatment of human immunodeficiency virus (HIV) patients, especially in Sub-Saharan Africa, where it remains a significant menace. Addressing this problem is crucial in improving health outcomes and the reduction of the burden of diseases in this vulnerable category of patients. OBJECTIVE: To determine the prevalence of community-acquired typical pneumonia among HIV patients in Public Hospitals in southern Ethiopia. METHODS: A cross-sectional study was done among 386 HIV patients clinically suspected of typical pneumonia attending the anti-retroviral therapy (ART) clinics of two hospitals from March to September 2022. A pretested structured questionnaire was employed to collect the demographic, clinical, and behavioral data. Sputum samples were collected and inspected for bacteria following standard procedures, and antimicrobial susceptibility testing was performed employing the Kirby-Bauer disk diffusion method. Besides, extended-spectrum ß-lactamase (ESßL) and carbapenemase-producing Gram-negative bacteria were inspected by the double disk synergy test and modified carbapenem inactivation method. Descriptive and inferential statistical analyses were also done. RESULTS: Overall, 39.1% (151/386) of sputum cultures (95% Confidence Interval: 32.4-44) were bacteriologically positive. A total of 151 bacteria were identified, comprising 72.8% (n = 110) of Gram-negative bacteria. The predominant isolate was Klebsiella pneumoniae (25.8%, n = 39), followed by Staphylococcus aureus (17.9%, n = 27); 59.6% (n = 90) of the entire isolates were multidrug-resistant (MDR). Forty percent (11/27) of S. aureus were methicillin-resistant S. aureus (MRSA), and 28.1% (n = 31) and 20.9% (n = 23) of Gram-negative bacteria were extended-spectrum beta-lactamases (ESBL) and carbapenemase producers, respectively. Occupational status, alcohol consumption, cluster of differentiation4 (CD4) Thymocyte cell count < 350, interruption of trimethoprim-sulfamethoxazole prophylaxis and antiretroviral treatment, and recent viral load ≥ 150 were found statistically significant. CONCLUSION: The higher rates of MDR, MRSA, ESBL, and carbapenem-resistant Enterobacterales (CRE) indicate that bacterial pneumonia is a vexing problem among HIV patients and therefore it is advisable to implement an antimicrobial stewardship program in the study area.

Reproductive tract infections (RTIs) are a persistent public health threat worldwide, particularly among women in low-income countries of Africa, including Ethiopia, where drug resistance is also a growing problem. It is crucial to address this problem to ensure women's health and well-being. A cross-sectional study was carried out among a cohort of 398 women of reproductive age who sought medical attention at the Gynecology Department of the Arba Minch General Hospital, southern Ethiopia, from January to June 2020. They were chosen through systematic random sampling, and a pre-tested structured questionnaire was used to collect the data. The collection of vaginal and/or cervical swabs were done to diagnose bacterial vaginosis (BV) and aerobic vaginitis (AV) using Nugent and AV score analyses, respectively. The swabs were subjected to standard microbiological culture techniques to detect the isolates causing AV and vaginal candidiasis (VC). The susceptibility profiles of the causative agents of AV were checked by the Kirby-Bauer disc diffusion technique. Descriptive and inferential statistical analyses were also done. Aerobic vaginitis was the predominantly diagnosed RTI (n = 122, 30.7%), followed by BV (n = 117, 29.4%) and VC (n = 111, 27.9%). The prominent bacteria of AV were Escherichia coli (n = 36, 34.2%) and Klebsiella pneumoniae (n = 30, 28.5%). The overall rate of multidrug-resistant (MDR) bacteria was 65.71% (n = 69). History of abortion (p = 0.01; AOR = 4.0, 95% CI = 2.1, 7.7) and the habit of using vaginal pH-altering contraceptives (p = 0.01; AOR = 4.7, 95% CI = 2.5, 8.8) have the greatest odds of RTI. The high prevalence of RTIs in our study warrants an urgent intervention to minimize the associated morbidities and complications. The overall rate of MDR bacterial isolates necessitates the implementation of an effective surveillance program in the study setting.

The emergence of drug-resistant Gram-negative bacterial uropathogens poses a grave threat worldwide, howbeit studies on their magnitude are limited in most African countries, including Ethiopia. Therefore, measuring the extent of their drug resistance is essential for developing strategies to confine the spread. A cross-sectional study was conducted at title hospital from 01 June to 31 August 2020. Midstream urine specimens were collected and inoculated onto MacConkey agar. Positive urine cultures showing significant bacteriuria as per the Kass count (>105 CFU/mL) were further subjected to biochemical tests to identify the type of uropathogens. Antimicrobial susceptibility testing was performed by the Kirby-Bauer disk diffusion technique, and potential carbapenemase producers were phenotypically determined by the modified carbapenem inactivation method as per the CLSI guidelines. Data were analyzed using SPSS version 26; P-value <0.05 was considered statistically significant. Totally, 422 patients were included, and the majority were females (54.7%). The prevalence of carbapenem-resistant Gram-negative uropathogens was 12.9%, and 64.7% of them were carbapenemase producers. Klebsiella pneumoniae (n = 5) was the predominant carbapenemase producer, followed by Pseudomonas aeruginosa (n = 4). Consumption of antibiotics prior to six months of commencement of the study, the presence of chronic diseases and hospitalizations were statistically associated with UTI caused by carbapenem-resistant Gram-negative uropathogens. Carbapenemase producers were resistant to most of the antibiotics tested. Our findings highlight the need for periodic regional bacteriological surveillance programs to guide empirical antibiotic therapy of UTI.

Individuals with Methicillin-Resistant Staphylococcus aureus (MRSA) colonized nasal cavities were at greater risk of developing the infection and can serve as potential reservoirs of transmission. Aim of this study is to determine the extent of nasal carriage and associated factors linked to MRSA in medical and health science students of Arba Minch University (AMU), Ethiopia, who are much prone. An institution based cross-sectional study was conducted at AMU from 01st August through 30th November, 2020 by means of a systematic sampling technique using a structured questionnaire. Nasal swabs samples were collected and S. aureus were identified following standard microbiological methods. Methicillin resistance was tested using cefoxitin disk and antimicrobial susceptibility tests were performed by Kirby-Bauer disk diffusion. Biofilm forming ability was phenotypically detected by micro-titer plate assay. Descriptive statistics and multivariable logistic regression analysis were done by Statistical Package for Social Service (SPSS) version 25. The overall prevalence of Staphylococcus aureus and MRSA were 27.1% (70/258) and 7.4% (19/258) respectively. Methicillin-Resistant S. aureus carriage were higher among medical interns, 16.9% (11/65). Isolates in general were co-resistant to antibiotics, such as trimethoprim-sulfamethoxazole (63.2%) and tetracycline (48.4%). Multidrug resistance (MDR) were observed among 52.6% (10/19) of the isolates. Besides, 31.4% (6/19) of MRSA were biofilm producers and all of them were MDR. Multivariable analysis showed that mean exposure for > 2 years to hospital settings [p = 0.048, AOR: 4.99, 95% CI 1.01-24.66] and the habit of sharing clothing and sports equipment [p = 0.017, AOR: 5.43, 95% CI 1.35-21.83] were statistically significant. The overall prevalence of nasal colonized MRSA among students were comparatively lower than that observed in other studies done in Ethiopia itself. An alarming factor is that, 60% of MDR-MRSA were biofilm producers.

Bacterial biofilms are a big menace to industries and the environment and also in the health sector, accumulation of which is a major challenge. Despite intensive efforts to curb this issue, a definitive solution is yet to be achieved. Enzyme-templated disruption of the extracellular matrix of biofilm and its control and elimination are emerging as an efficient and greener strategy. The study describes the antibiofilm potential of alpha-amylase from the marine microorganism Pantoea agglomerans PCI05, against food-borne pathogens. Amylase exhibited stability in a wide pH range and retained 50% of its activity at temperatures as high as 100°C. Thermal analysis of the enzyme produced showed thermal stability, up to 130°C. From these findings, it can be envisaged that the alpha-amylase produced from P. agglomerans can be used for starch liquefaction; it was also evaluated for antibiofilm activity. Amylase from this marine bacterium was found to efficiently disrupt the preformed biofilms of food-borne pathogens such as Bacillus cereus, Serratia marcescens, Vibrio parahaemolyticus, Listeria monocytogenes, and Salmonella enterica enterica serotype Typhi based on the value of biofilm inhibitory concentrations.
RESUMEN
BACKGROUND: Mangroves contain several bioactive compounds, some of which have been used for centuries as remedies for several ailments. METHODS: Foliar parts of Excoecaria agallocha were extracted in organic solvents and in water using a Soxhlet apparatus and evaluated for antimicrobial activity against nine type-culture pathogens, six clinical isolates, and two fungal pathogens with agar well diffusion assays. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by broth dilution and extracts further subjected to brine-shrimp cytotoxic assays using Artemia salina. Chemical constituents were analyzed with thin-layer chromatography (TLC), gas chromatography-mass spectroscopy (GC-MS), and Fourier-transform infrared spectroscopy (FT-IR). RESULTS AND DISCUSSION: Ethyl acetate extract displayed the broadest antimicrobial activity. Isolates of Staphylococcus aureus were found to be the most susceptible among the clinical and type-culture groups corresponding to inhibition zones: 17.3±1.1 and 23.5±1.3 mm in diameter, respectively. Anticandidal activity was found to be lower against Candida albicans and C. tropicalis (10.3±0.6 and 11.9±0.85 mm diameter). Also, this extract was found to be bactericidal for S. aureus and Micrococcus luteus (MBC:MIC ≤2). C cytotoxic activity LD50 was 521 µg/mL. On GC-MS, squalene [(6E, 10E, 4E, 18E)-2,6,10,15,19,23-hexamethyltetracosa-2,6,10,14,18,22-hexaene] was the major compound. Bioassay-guided (antibacterial) TLC revealed the presence of one major active fraction, F2, with an Rf value of 1.21. FT-IR analysis of this fraction also implied that it was squalene, which might have a functional role in the mechanism of chemical defense.
RESUMEN
Background: Coinfection with malaria and typhoid fever is a major public health issue in developing countries. In endemic areas, including Ethiopia, people are at risk of acquiring both malaria and typhoid fever at the same time. Therefore, this study aimed to determine the magnitude of malaria-typhoid fever coinfection in febrile patients attending hospital at Southern Ethiopia. Methods: A hospital-based cross-sectional study was carried out on 416 febrile patients attending Arba Minch General Hospital from 1st October to 30th December 2021. The data was collected using a pretested structured questionnaire. Capillary and Venus blood samples were collected for assessing malaria and typhoid fever, respectively. Blood smear, culture, and biochemical tests were performed based on standard parasitological and microbiological methods. The P-value ≤ 0.05 was considered statistically significant. Results: The magnitude of malaria, typhoid fever, and their coinfections was 26.2% (109/416), 6.5% (27/416), and 3.1% (13/416), respectively. Among the confirmed malaria cases, about 66% of infections were Plasmodium falciparum. The malaria-typhoid fever coinfection showed a statistically significant association with a clinical presentation of a continuous pattern of fever (AOR = 5.84; 95% CI: 1.44-23.71, P = 0.014) and chills (AOR = 3.94; 95% CI: 1.04-14.89, P = 0.044). About 29.6% of Salmonella isolates were multidrug-resistant (MDR). Conclusion: The total rate of coinfection with malaria and typhoid fever was comparable to that of previous studies. With the consideration of higher prevalence of drug resistance of Salmonella spp. and higher prevalence of malaria-typhoid fever coinfection, proper diagnostic procedure should be implemented for proper use of drugs.
RESUMEN
Bacterial bloodstream infections are of great concern globally. Of late, the emergence of drug resistant bacteria worsen the related morbidity and mortality. This study was aimed to determine the bacterial profile, antimicrobial susceptibility patterns, and associated factors among the blood stream infection (BSI) suspected patients attending the Arba Minch General Hospital (AMGH), southern Ethiopia, from 01 June through 31st August, 2020. A cross-sectional study was conducted among 225 BSI suspected patients. Systematic random sampling method was used to select patients. Blood culture was done to isolate bacterial pathogens. Antimicrobial susceptibility test was performed by employing the Kirby-Bauer disc diffusion method. Descriptive statistics and multivariable logistic regression analysis were done by Statistical Package for Social Service (SPSS) version 22. The rate of prevalence of bacteriologically confirmed cases was 22/225 (9.8%). Majority of BSI were caused by Gram-positive cocci, 13/22 (59.1%), particularly the isolates of S. aureus, 7/22 (31.8%) followed by Enterococci species, 4/22 (18.2%) and coagulase-negative Staphylococci (CoNS), 2/22 (9.1%). Among the Gram-negative bacteria 9/22 (41.1%), Klebsiella species 4/22 (18.2%) was the prominent one followed by Escherichia coli 2/22 (9.1%), Pseudomonas aeruginosa 2/22 (9.1%), and Enterobacter species 1/22 (4.5%). All the isolates of Gram-negative bacteria were susceptible to meropenem whereas 69.2% of the isolates of Gram-positive counterparts were susceptible to erythromycin. Slightly above two third (68.2%) of the total isolates were multidrug resistant. Insertion of a peripheral intravenous line was significantly associated with BSI [p = 0.03; Adjusted Odds Ratio = 4.82; (Confidence Interval: 1.08-21.46)]. Overall results revealed that eventhough the prevalence of BSI in Arba Minch is comparatively lower (9.8%), multidrug resistance is alarmingly on the rise, which is to be addressed through effective surveillance and control strategies.

BACKGROUND: In developing countries, the prevalence of bacterial infections is quite rampant due to several factors such as the HIV/AIDS pandemic, lack of hygiene, overcrowding, and resistance to conventional antimicrobials. Hence the use of plant-based antimicrobial agents could provide a low-cost alternative therapy. Rosmarinus officinalis is reputed as a medicinal plant in Ethiopia; however, its antibacterial activity against many of the clinical isolates remains overlooked. METHODS: Tender foliage of R. officinalis was collected and extracted in ethanol (EtOH) and evaluated for their antimicrobial activity against ten multidrug-resistant (MDR) clinical isolates, human type culture pathogens, and meat-borne bacterial isolates by employing agar well diffusion assay. RESULTS: EtOH extract of R. officinalis efficiently subdued the growth of all tested MDR clinical isolates in varying degrees. Salmonella sp. and Staphylococcus aureus were found to be the most sensitive clinical isolates. Likewise, it efficiently repressed the growth of meat-borne pathogens, particularly, S. aureus and Salmonella sp. showing its potentiality to be used as a natural antibacterial agent in the meat processing industry. The mechanism of antibiosis of plant extract against meat-borne pathogens is inferred to be bactericidal. Chemical constituents of the crude plant extract were analysed by Gas Chromatography-Mass Spectroscopy (GC-MS), Fourier Transform Infrared (FT-IR), and UV-visible spectroscopy showing genkwanin (26%), camphor (13%), endo-borneol (13%), alpha-terpineol (12%), and hydroxyhydrocaffeic acid (13%) as the major compounds. CONCLUSION: Overall results of the present study conclude that R. officinalis could be an excellent source of antimicrobial agents for the management of drug-resistant bacteria as well as meat-borne pathogens.
RESUMEN
INTODUCTION: Patient-care equipment and inanimate objects contaminated with bacteria are a persistent problem in countries like Ethiopia, and remain overlooked. This study aimed to elucidate the magnitude of contaminations, diversity, and antimicrobial-susceptibility patterns of bacterial isolates from selected wards of Arba Minch General Hospital, Ethiopia. METHODS: Samples were inoculated into bacteriological media and identified by biochemical characterization, followed by antimicrobial-susceptibility tests. RESULTS: Of the 99 inanimate objects and items of patient-care equipment examined, 71 (71.7%) showed contamination: 26 (76.4%) from the surgical ward and 22 (66.6%) and 23 (71.8%), respectively, from the pediatric ward and neonatal intensive care unit. In the case of Gram-positive bacteria, coagulase-negative staphylococci (CoNS; 52.2%) were predominant, followed by Staphylococcus aureus (47.7%), whereas common Gram-negative counterparts were Acinetobacter spp. (28.5%) and Klebsiella spp. (23.8%). Antibiograms of S. aureus and CoNS showed 100% and 78% resistance, respectively, against penicillin. Isolates of Acinetobacter spp. showed 100% resistance to ceftriaxone and ampicillin, whereas those of Klebsiella spp. displayed complete resistance against ampicillin and trimethoprim-sulfamethoxazole. All isolates of Citrobacter spp., Enterobacter spp., Salmonella spp., Escherichia coli, and Serratia spp. exhibited 100% resistance to amoxicillin, ampicillin, and trimethoprim-sulfamethoxazole. Overall prevalence of multidrug-resistant bacteria was 57.7%. CONCLUSION: A stringent infection-vigilance program comprising routine sampling from equipment and inanimate objects combined with antimicrobial-resistance surveillance and decontamination efforts must be instituted promptly.
RESUMEN
BACKGROUND: The Rhesus (Rh) blood group system is the next most clinically significant blood group system following the ABO blood group. Rh D-negative women are at risk of alloimmunization following exposure to Rh D-positive blood. The exposure of Rh D-negative women to Rh D-positive fetal blood may cause hemolytic disease of the fetus or new-born due to Rh incompatibility. Knowing Rh blood phenotype has paramount importance to prevent the risk of sensitization and bad obstetric outcome in Rh D-negative women. Despite the aforementioned fact, the distribution of Rh D-negative phenotype of women was not explored in Arba Minch Zuria district, southern Ethiopia. This study was aimed to assess the prevalence of Rh D-negative blood phenotype among reproductive-age women in Arba Minch Zuria district, southern Ethiopia. METHODS AND MATERIALS: A community-based cross-sectional study was conducted among reproductive-age women in Arba Minch Zuria district, Southern Ethiopia from March to April 2019. Socio-demographic data were collected using an interviewer-administered semi-structured questionnaire and blood phenotype determination was done by laboratory technicians using the slide method principle aseptically and Statistical Package for Social Science (SPSS) version 21 was used for analysis. RESULT: The data were collected from 417 study participants with a 98.8% response rate. This study revealed that 2.1%, 1.9%, 1.2%, and 1% of study participants with blood group O, A, B, and AB were Rh D negative, respectively. In this study, the overall prevalence of Rh D negative phenotype was found 6.2% among reproductive-age women in Arba Minch Zuria district, Southern Ethiopia. CONCLUSIONS: This study showed a high prevalence of Rh D negative factor among reproductive-age women in Arba Minch Zuria district. Therefore, counseling of reproductive age women on the importance of Rh D factor status determination would be worthy to avoid the potential risk of sensitization among Rh D negative women in order to prevent hemolytic disease of the fetus and new-born.

BACKGROUND: The incidence of hospital-acquired enterobacteria that produce extended-spectrum beta-lactamases (ESBLs) is on the rise worldwide. Colonization of gastrointestinal tract by extended-spectrum beta-lactamase Enterobacteriaceae, a prominent causative agent, results in life-threatening infections. OBJECTIVE: To determine the rate of gastrointestinal colonization by extended-spectrum beta-lactamase- and carbapenemase-producing Enterobacteriaceae and also to elucidate the antibiotic susceptibility profile and associated risk factors among hospitalized patients in Arba Minch General Hospital, Ethiopia. METHODOLOGY: A facility-based cross-sectional study was conducted in Arba Minch General Hospital from May 2018 to July 2019. Sociodemographic data and associated factors were collected using a pre-tested-structured questionnaire. Stool specimens were collected using sterile stool cups. Each sample was then inoculated onto MacConkey agar. Bacterial isolates were identified using various biochemical tests. Screening and confirmatory tests for extended-spectrum beta-lactamase- and carbapenemase-producing Enterobacteriaceae were performed using the modified Kirby-Bauer disc diffusion technique. Statistical package for Social Science was used to analyze the data. The P-value ≤0.05 was considered as statistically significant. RESULTS: A total of 421 hospitalized patients were enrolled in this study of which there were 240 (57%) females. The mean age of the study participants was 28.8 with SD of 15.7. Majority of participants were in the age range of 25-40 years 179 (42.5%). About 146 (34.7%) participants were found to be colonized by extended-spectrum beta-lactamase-producing Enterobacteriaceae. The predominant ESBL-producing isolates were Escherichia coli 62 (42.46%) followed by Klebsiella pneumoniae 60 (41.09%). Six (1.43%) carbapenemase-producing K. pneumoniae were isolated. ESBL-producing Enterobacteriaceae showed higher resistance against tetracycline (91.1%) and cotrimoxazole (93.84%). Colonization of the gastrointestinal tract by ESBL showed statistically significant association with regard to chronic diseases (p<0.001) and the administration of oral antibiotics after admission (p=0.020). CONCLUSION: The overall colonization rate of the gastrointestinal tract by extended-spectrum beta-lactamase-producing Enterobacteriaceae was prominent. The extended-spectrum beta-lactamase-producing isolates exhibited a higher level of resistance against the commonly used antibiotics which further needs greater attention.
