ABSTRACT

BACKGROUND/AIMS: Coronary heart disease morbidity and mortality are higher in people of South Asian origin than in those of African origin. We investigated whether as young adults without diabetes, people in Mauritius of South Asian descent (Indians) would show a more adverse cardiovascular risk profile that those of predominantly African descent (Creoles), and whether this could be explained by ethnic differences in visceral adiposity or other fat distribution patterns. METHODS: The study was conducted in 189 young non-physically active adults, with the following measurements conducted after an overnight fast: anthropometry (weight, height, waist circumference), whole-body and regional body composition by dual-energy x-ray absorptiometry, blood pressure, and blood assays for glycemic (glucose and HbA1c) and lipid profile (triglycerides and cholesterols). RESULTS: The results indicate higher serum triglycerides and lower HDL cholesterol in men than in women, and in Indians than in Creoles (p < 0.001). No significant differences due to sex or ethnicity are observed in body mass index and waist circumference, but indices of visceral adiposity (visceral/android, visceral/subcutaneous) and visceral-to-peripheral adiposity ratio (visceral/gynoid, visceral/limb) were significantly higher in men than in women, and in Indians than in Creoles. The significant effects of sex and ethnicity on blood lipid profile were either completely abolished or reduced to a greater extent after adjusting for the ratio of visceral-to-peripheral adiposity than for visceral adiposity per se. CONCLUSIONS: In young adults in Mauritius, Indians show a more adverse pattern of body fat distribution and blood lipid risk profile than Creoles. Differences in their fat distribution patterns, however, only partially explain their differential atherogenic lipid risk profile, amid a greater impact of visceral-to-peripheral adiposity ratio than that of visceral adiposity per se on sex and ethnic differences in cardiovascular risks; the former possibly reflecting the ratio of hazardous (visceral) adiposity and protective (peripheral) superficial subcutaneous adiposity.

ABSTRACT

Disentangling the effects of ecological disruptions operating at different spatial and temporal scales in shaping past species' demography is particularly important in the current context of rapid environmental changes driven by both local and regional factors. We argue that volcanic oceanic islands provide useful settings to study the influence of past ecological disruptions operating at local and regional scales on population demographic histories. We investigate potential drivers of past population dynamics for three closely related species of passerine birds from two volcanic oceanic islands, Reunion and Mauritius (Mascarene archipelago), with distinct volcanic history. Using ABC and PSMC inferences from complete genomes, we reconstructed the demographic history of the Reunion Grey White-eye (Zosterops borbonicus (Pennant, 1781)), the Reunion Olive White-eye (Z. olivaceus (Linnaeus, 1766)) and the Mauritius Grey White-eye (Z. mauritianus (Gmelin, 1789)) and searched for possible causes underlying similarities or differences between species living on the same or different islands. Both demographic inferences strongly support ancient and long-term expansions in all species. They also reveal different trajectories between species inhabiting different islands, but consistent demographic trajectories in species or populations from the same island. Species from Reunion appear to have experienced synchronous reductions in population size during the Last Glacial Maximum, a trend not seen in the Mauritian species. Overall, this study suggests that local events may have played a role in shaping population trajectories of these island species. It also highlights the potential of our conceptual framework to disentangle the effects of local and regional drivers on past species' demography and long-term population processes.

ABSTRACT

Bacterial adaptation is facilitated by the presence of mobile genetic elements and horizontal gene transfer of genes, such as those coding for virulence factors or resistance to antimicrobial compounds. A hybrid assembly of Nanopore MinIon long-read and Illumina short-read data was produced from a copper-resistant Xanthomonas campestris pv. campestris strain isolated from symptomatic broccoli leaves in Mauritius. We obtained a 5.2-Mb high-quality chromosome and no plasmid. We found four genomic islands, three of which were characterized as integrative conjugative elements or integrative mobilizable elements. These genomic islands carried type III effectors and the copper resistance copLABMGF system involved in pathogenicity and environmental adaptation, respectively.

ABSTRACT

BACKGROUND: Persons with disabilities experience higher risks of mortality as well as poorer health as compared to the general population. The aim of this study is to estimate the correlations between functional difficulties across several domains in six countries. METHODS: National census data with questions on disability from six countries (Mauritius, Morocco, Senegal, Myanmar, Vietnam, and Uruguay) was used in this study. We performed logistic regressions to assess the extent to which having a functional difficulty in one domain is correlated with having a functional difficulty in each of the other domains and report weighted odds ratios (ORs) overall and within age-groups ('18-44' years and '45+' years). Models adjust for age, sex, and location (rural or urban). Sensitivity analyses around different choices of predictors and response variables were conducted. FINDINGS: For all countries, reporting a functional difficulty in one domain was consistently and significantly positively correlated with reporting a functional difficulty in other domains (overall) and for each of the two age-groups considered - '18-44' years and '45+' years. All ORs were greater than one. Cognition, mobility, and hearing were the domains that were the most correlated ones with other domains. The highest pairwise correlations were for i/ hearing and cognition; ii/ mobility and cognition. Results were robust to changing the severity thresholds for functional difficulties. Across countries, Uruguay, the only high-income country among the six countries under study, had the lowest correlations between functional domains. CONCLUSIONS: There are consistent positive associations in the experience of functional difficulties in various domains in the six countries under study. Such correlations may reflect barriers to social services including healthcare services and resources (e.g. assistive devices) that may lead to an avoidable deterioration of functioning across domains. Further research is needed on the trajectories of functional difficulties and on structural barriers that people with functional difficulties may experience in their communities and in healthcare settings in particular. This is important as some functional difficulties may be preventable.

ABSTRACT

Over the past decade, ancient genomics has been used in the study of various pathogens. In this context, herbarium specimens provide a precious source of dated and preserved DNA material, enabling a better understanding of plant disease emergences and pathogen evolutionary history. We report here the first historical genome of a crop bacterial pathogen, Xanthomonas citri pv. citri (Xci), obtained from an infected herbarium specimen dating back to 1937. Comparing the 1937 genome within a large set of modern genomes, we reconstructed their phylogenetic relationships and estimated evolutionary parameters using Bayesian tip-calibration inferences. The arrival of Xci in the South West Indian Ocean islands was dated to the 19th century, probably linked to human migrations following slavery abolishment. We also assessed the metagenomic community of the herbarium specimen, showed its authenticity using DNA damage patterns, and investigated its genomic features including functional SNPs and gene content, with a focus on virulence factors.

ABSTRACT

BACKGROUND: The goal of universal health coverage (UHC) is that every individual has access to high-quality health services without running the consequences of financial hardship. The World health report 2013 "Research for universal health coverage" states a performant National Health Research Systems (NHRS) can contribute by providing solutions to challenges encountered in advancing towards UHC by 2030. Pang et al. define a NHRS as the people, institutions, and activities whose primary aim is to generate and promote utilization of high-quality knowledge that can be used to promote, restore, and/or maintain the health status of populations. The WHO Regional Committee for Africa (RC) adopted a resolution in 2015 urging member states to strengthen their NHRS to facilitate production and utilization of evidence in policy development, planning, product development, innovation, and decision-making. This study aimed to calculate NHRS barometer scores for Mauritius in 2020, identify the gaps in NHRS performance, and recommend interventions for boosting the Mauritius NHRS in the pursuit of UHC. METHODS: The study used a cross-sectional survey design. A semi-structured NHRS questionnaire was administered and complemented with a review of documents archived in pertinent Mauritius Government Ministries, universities, research-oriented departments, and non-governmental organizations websites. The African NHRS barometer developed in 2016 for countries to monitor the RC resolution implementation was applied. The barometer consists of four NHRS functions (leadership and governance, developing and sustaining resources, producing and utilizing research, financing research for health [R4H]), and 17 sub-functions, e.g., existence of a national policy on research for health (R4H), presence of a Mauritius Research and Innovation Council (MRIC), existence of knowledge translation platform. RESULTS: In 2020, Mauritius had an overall average NHRS barometer score of 60.84%. The four NHRS functions average indices were 50.0% for leadership and governance, 77.0% for developing and sustaining resources, 52.0% for producing and utilizing R4H, and 58.2% for financing R4H. CONCLUSION: The performance of NHRS could be improved through the development of a national R4H policy, strategic plan, prioritized agenda, and national multi-stakeholder health research management forum. Furthermore, increased funding for the NHRS may nurture the human resources for health research capacities, hence the number of pertinent publications and health innovations.

ABSTRACT

Microalgae are unicellular organisms and commonly present in the euphotic zone of marine ecosystems. From the western coast of Mauritius, three strains of Prorocentrum species were isolated from macrophytes and cultured under standard laboratory conditions. Morphologies were examined by light, fluorescence, and scanning electron microscopy, and phylogenetic analyses were based on partial large subunit LSU rDNA (D1-D2) and ITS1-5.8S-ITS2 (ITS) regions. Three Prorocentrum species, including the P. fukuyoi complex, P. rhathymum, and P. lima complex, were identified. The antimicrobial activities were assayed against potential human pathogenic bacterial strains. The highest zone of inhibition was recorded for intracellular and extracellular protein extracts of Prorocentrum rhathymum against Vibrio parahaemolyticus. The polysaccharide extracts of the Prorocentrum fukuyoi complex had a higher zone of inhibition (24 ± 0.4 mm) against MRSA at a minimum concentration of 0.625 µg/mL. The extracts from the three Prorocentrum species had different levels of activity against the pathogens used, and this can be of scientific interest in the search for antibiotics from natural marine sources.

ABSTRACT

Significant climate finance gaps exist for small islands in transitioning to net zero, as climate commitments far outweigh the government budget and international financing. To create alignment between resource allocation and climate commitments, a roadmap for strategic and cost-effective decarbonization is of supreme importance. This paper presents a geographic carbon accounting model which incorporates emissions from electricity, transportation, food systems, and human respiration, whilst accounting for the carbon uptake by the terrestrial biosphere in view of identifying high-intensity aggregated emissions estimated in the range of 200-215 ktCO2e in the coastal and inland urban regions of the remote island of Mauritius. An estimated 4641 ktCO2e, representing 79.4% of overall emissions, has been observed to originate from buildings, food, and waste systems. About 1150 ktCO2e, accounting for a share of 19.7%, is derived from transport systems. The study advocates for the enhanced participation of local authorities to better contribute to climate governance, whilst supporting legislative, financial, technological, and behavioural reforms. Despite the relatively low sequestration potential of forests replacing all non-habitable lands, which is estimated at 1002 ktCO2e and representing about 17.1% of annual net emissions, afforestation programmes are encouraged owing to multiple ecosystem services provided by trees.

ABSTRACT

Long-tailed macaques are the predominant nonhuman primate species for the nonclinical safety testing of biopharmaceuticals. This species comprises 9 subspecies with Macaca fascicularis fascicularis naturally occurring in Southeast Asia. Since the 17th century, M. f. fascicularis also occurs on Mauritius. Cynomolgus macaques do not naturally occur in China, but are bred in many farms across the country. The current shortage in animal supply raises the question whether geographical animal origin matters and if animals from different geographical regions can be combined on a drug development program or even a single experiment. This article reviews geographical animal origin in relation to selected endpoints that are relevant in nonclinical drug safety testing. Animals from different countries within Asia mainland do not appear to show any meaningful difference. Very little data are available for animals from Asia island. Mauritian animals show consistent differences from Asian animals in several clinical and anatomical pathology parameters. For developmental parameters, animals from Mauritius and Asia are comparable with the exception that Mauritian animals mature faster. In the authors' view, differences between the geographical clusters can be accounted for as long as baseline and reference data are available.

ABSTRACT

To investigate the influence of geographical origin, age, and sex on toxicologically relevant spontaneous histopathology findings in cynomolgus macaques (Macaca fascicularis), we performed a comparative analysis of historical control data (HCD) from 13 test sites that included 3351 animals (1645 females and 1706 males) sourced from Mauritius, China, Vietnam, and Cambodia, aged from 2 to 9.5 years, and from 446 toxicology studies evaluated between 2016 and 2021. The most common findings were mononuclear infiltrates in the kidney, liver, brain, and lung, which showed highest incidences in Mauritian macaques, and heart, salivary glands, and gastrointestinal tract (GIT), which showed highest incidences of mononuclear infiltrates in mainland Asian macaques. Developmental and degenerative findings were more common in Mauritian macaques, while lymphoid hyperplasia and lung pigment showed higher incidences in Asian macaques. Various sex and age-related differences were also present. Despite origin-related differences, the similarities in the nature and distribution of background lesions indicate that macaques from all geographical regions are suitable for toxicity testing and show comparable lesion spectrum. However, in a toxicity study, it is strongly recommended to use animals from a single geographical origin and to follow published guidelines when using HCD to evaluate and interpretate commonly diagnosed spontaneous lesions.

ABSTRACT

Cynomolgus macaques (Macaca fascicularis) are commonly used in safety assessment and as translational models for drug development. Recent supply chain pressures, exportation bans, and increased demand for drug safety assessment studies exacerbated by the COVID-19 pandemic have prompted the investigation of utilizing macaques of different geographic origin in preclinical toxicity studies. This study compares routine hematology, coagulation, and clinical chemistry endpoints of 3 distinct subpopulations of mainland Asia origin (Cambodia, China, and Vietnam) with Mauritius origin macaques compiling results of 3,225 animals from 123 regulatory toxicology studies conducted at North American and European Union contract research organization facilities between 2016 and 2019. Results were generally similar amongst the subpopulations compared in this study. Few notable differences in hematology test results and several minor differences in serum biochemistry and coagulation test results were identified when 3 distinct subpopulations of mainland Asia origin macaques were compared with Mauritius origin macaques. Our findings support the use of different origin macaques in drug development programs; however, emphasizes the importance of maintaining consistency in geographic origin of animals within a study.

ABSTRACT

Taxes on sugar-sweetened beverages (SSBs) are relatively new and there is limited evidence about their impact on SSB consumption or body mass index (BMI) (as opposed to prices, purchases, or sales), their impact on youth (as opposed to adults), or their impact in non-Western nations. This paper adds to the evidence across all these dimensions by estimating the effect of an SSB tax on SSB consumption and the BMI of youth in Mauritius, an island nation in the Indian Ocean, which we compare to Maldives, another island nation which did not implement an SSB tax during the time of our data. Results of difference-in-differences models indicate that the tax in Mauritius had no detectable impact on the consumption of SSBs or the BMI of the pooled sample of boys and girls. However, models estimated separately by sex indicate that the probability that boys consumed SSBs fell by 9.4 percentage points (11%). These are among the first estimates of the effect of SSB taxes on youth consumption and contribute to the limited evidence on the impact of SSB taxes on weight, and in non-Western countries.

ABSTRACT

OBJECTIVES: The objective of this study is to assess the determinants of willingness to pay to enhance pandemic preparedness in Mauritius. STUDY DESIGN: A contingent valuation method is used to estimate willingness to pay to pay for enhancing pandemic preparedness using a sample of working people in Mauritius. METHODS: A two-phase decision process analysis is carried out to model the willingness to pay to enhance pandemic preparedness. The first phase is to analyse the respondents' decision of whether or not to pay for enhancing pandemic preparedness using a Probit model. The second phase is to estimate the determinants of the amount of money respondents are willing to pay using a Tobit model. RESULTS: Income earners are willing to pay an average of Rs. 1,900 (approximately USD 50) per annum to enhance pandemic preparedness. 'Perceived Response Efficacy', 'Awareness of the Need and Responsibility for Paying', 'Subjective Obligation to Pay' and the 'Theory of Planned Behaviour' are found to affect both stages of of the decision-making process. Knowledge on COVID-19 is found to have a positive impact on the decision to pay and health responsibility attitude is found to have a negative impact on the amount people are willing to pay. CONCLUSIONS: On average, the government can potentially expect to mobilise an additional Rs. 1,047,470,000 (USD 27,565,000) from taxpayers to spend on enhancing pandemic preparedness in Mauritius. To increase willingness to pay for enhanced pandemic preparedness, the government can focus on improving knowledge on a pandemic, perceived response efficacy and awareness on need and responsibility of paying.

ABSTRACT

Microplastics had been collected at two sites namely Trou d'eau Douce (TD) and La Cambuse (LC) public beaches, lying in the east coast and south-east coast of Mauritius, respectively, over 6 months from September 2019 to February 2020. The sizes of the latter varied from 180 µm to 4 mm. A higher amount of microplastics collected/6-kg sand sample was recorded at LC. Two-way ANOVA revealed that (1) there was a considerable gap in the variability regarding quantity and size distribution of microplastics on the two beaches. The post-hoc analysis showed that the majority of the microplastics at LC were > 1.40 mm, whereas the smaller plastic fragments < 1.40 mm were more dominant at TD. (2) There was a significant interaction between location and event (p value = 0.025). The post-hoc analysis showed that the torrential rain hitting the island prior to sampling week 7 had decreased the microplastic counts at both TD and LC, but not significantly. Interestingly, the two hurricanes, prior to weeks 8 and 9, had appreciably reduced the microplastic counts at TD and, on the other hand, there was an increase in the amount of microplastics at LC, but not to a significant effect. The chemical nature (qualitative analysis) of microplastics was determined by density flotation and FTIR spectroscopy. Microplastics at TD were exclusively high-density polyethylene (HDPE) in origin, whereas, at LC, microplastics were both HDPE and polypropylene (PP) in origin.

ABSTRACT

The coating industry is one of the most important consumers of water and chemicals and consequently is a major water polluter in Mauritius. The focus of this study was to characterise wastewater generated by a coating industry in Mauritius. The objectives were to develop a wastewater sampling strategy and to analyse the pollutant parameters as per Mauritian regulations. The wastewater samples were analysed for physicochemical properties and metal abundances over a period of 6 months. The physicochemical parameters analysed were pH, electrical conductivity (EC), true colour, total suspended solids (TSS), biological oxygen demand (BOD5), chemical oxygen demand (COD), nitrate, phosphate, sulphate and free chlorine. The wastewater samples were also analysed for metal ions such as sodium, potassium, arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, mercury, molybdenum, nickel and zinc. The results of the physicochemical parameters indicated the presence of biologically resistant organic matters in all the wastewater samples with elevated values of BOD5 and COD, and low biodegradability index, respectively. The coating industry wastewater samples were acidic and saline in nature. Moreover, they presented high concentrations of TSS, free chlorine and sodium ions compared to standard limits promulgated by the Mauritian Government. Spearman's rank correlation matrix with non-linear regression analysis showed significant associations among the measured parameters which were found to have a common origin in the coating industry wastewater. This research will be useful for regular monitoring and setting up an adequate coating industry wastewater treatment for the potential reuse in production processes in Mauritius.

ABSTRACT

The chemical and pharmacological profiles of essential oils (EOs) hydrodistilled in yields of 0.03-0.77 % (w/w) from three exotic (Cinnamomum camphora, Petroselinum crispum, and Syzygium samarangense) and two endemic (Pittosporum senacia subsp. senacia and Syzygium coriaceum) medicinal plants were studied. GC-MS/GC-FID analysis of the EOs identified the most dominant components to be myristicin (40.3 %), myrcene (62.2 %), 1,8-cineole (54.0 %), ß-pinene (21.3 %) and (E)-ß-ocimene (24.4 %) in P. crispum, P. senacia and C. camphora, S. samarangense and S. coriaceum EOs, respectively. All EOs were found to possess anti-amylase (0.70-1.50 mM ACAE/g EO) and anti-tyrosinase (109.35-158.23 mg KAE/g) properties, whereas no glucosidase inhibition was displayed. Only Syzygium EOs acted as dual inhibitors of both acetyl- and butyryl-cholinesterases, while P. senacia and C. camphora EOs inhibited acetylcholinesterase selectively and P. crispum EO was inactive (AChE: 4.64-4.96 mg GALAE/g; BChE: 5.96 and 7.10 mg GALAE/g). Molecular docking revealed 1,8-cineole to present the best binding affinities with butyrylcholinesterase, amylase and tyrosinase, while both myristicin and ß-pinene with acetylcholinesterase and finally ß-pinene with glucosidase. In vitro antioxidant potency was also demonstrated in different assays (DPPH: 13.52-53.91 mg TE/g, ABTS: 5.49-75.62 mg TE/g; CUPRAC: 45.38-243.21 mg TE/g, FRAP: 42.49-110.64 mg TE/g; and phosphomolybdenum assay: 82.61-160.93 mM TE/g). Principal component analysis revealed the EOs to differ greatly in their bioactivities due to their chemodiversity. This study has unveiled some interesting preliminary pharmacological profiles of the EOs that could be explored for their potential applications as phytotherapeutics.

ABSTRACT

INTRODUCTION: Injuries are a major global health problem that affects teenagers in many countries. Though several studies have been done in many countries, little is known among adolescents in Mauritius. Therefore, our paper explored the prevalence and correlates of serious injuries among adolescents in Mauritius. METHODS: We analysed the 2017 Global School-Based Student Health Survey (GSHS) data from Mauritius, using the Chi-square test and binomial logistic regression analysis with adjusted odds ratio (AOR) at 95% confidence interval (CI). RESULTS: The prevalence of serious injuries among adolescents in Mauritius stood at 39.0%. Also, the predictors of serious injuries included sex (AOR = 0.70, CI = 0.58-0.81), physical attack (AOR = 0.47, CI = 0.39-0.57), being bullied (AOR = 0.48, CI = 0.48-0.70), suicide ideation (AOR = 0.65, CI = 0.49-0.85), hunger (AOR = 0.65, CI = 0.48-0.86), truancy from school (AOR = 0.77, CI = 0.63-0.93), marijuana use (AOR = 0.54, CI = 0.39-0.76), alcohol consumption (AOR = 0.64, CI = 0.70-0.98), and parental neglect (AOR = 0.83, CI = 0.70-0.98). CONCLUSION: The rate of injury among adolescents in Mauritius is moderately high, with sex, suicidal thought, hunger, truancy, drug use, and parental neglect as correlates. There is an urgent need for health promotion interventions at family, community, and school levels to deal with this level of serious injuries and the factors influencing such occurrences among these adolescents in Mauritius.

ABSTRACT

CONTEXT: This article explains the policy process that occasioned the development of comprehensive tobacco control policies in Mauritius from 1980 to 2019. It does so by drawing theoretical insights from John Kingdon's streams framework, historical institutionalism, and ideational perspectives to explicate how tobacco control rose to the status of government policy agenda. METHODS: The main sources of data are government documents, media reports, archival studies, grey literature, and published books and articles. These sources were supplemented by key informant interviews with government officials, civil society groups, and other vested interest groups. FINDINGS: This article finds that the prevalence of noncommunicable diseases in the late 1980s, the political commitment of Mauritius's Labour government to comprehensive tobacco control, the institutional legacies of Mauritius's Public Health Act of 1925, and the administrative capacity of Mauritius's Ministry of Health and Quality of Life are the primary factors that drove tobacco control policies in Mauritius. CONCLUSION: The findings from this study will enrich our understanding of policy change and the politics of tobacco control in the global south. Future research should investigate why some countries in Africa have failed to adopt comprehensive tobacco control policies despite ratifying the Framework Convention on Tobacco Control.

PURPOSE: Since there is no existing qualitative study on Type 1 Diabetes (T1D) in Mauritius, this study was undertaken to explore the lived experience of mothers having a child with T1D in Mauritius. DESIGN AND METHODS: This research work used a phenomenological approach with the interview of a purposeful sample of eleven mothers having a child diagnosed with T1D. Data collected was analyzed by two independent investigators. Ethical clearance was obtained from the Department of Medicine Ethics Committee of the University of Mauritius. RESULTS: The emerging themes were 'Facing disruption in life', 'Experiencing mixed feelings', 'Taking matters in hands' and 'Coping with life'. They put forward the four major components of the lived experience of being the mother of a child diagnosed with T1D. 3 to 4 minor themes. CONCLUSIONS: The study shows that diagnosis of Type 1 Diabetes in a child has a profound psychosocial impact on mother's personal, family and professional lives. There is need to support parents in the delivery of optimal care to their child to avoid unpredictable complications and unnecessary loss of lives. PRACTICE IMPLICATIONS: Both nurses and doctors should be aware of their crucial role in demonstrating empathy towards parents/children affected by T1D. There is a need for training programs to develop a culture where empathy enhances nursing and medical practice.

ABSTRACT

The recent emergence of Zika virus (ZIKV) in Brazil and the increasing resistance developed by pathogenic bacteria to nearly all existing antibiotics should be taken as a wakeup call for the international authority as this represents a risk for global public health. The lack of antiviral drugs and effective antibiotics on the market triggers the need to search for safe therapeutics from medicinal plants to fight viral and microbial infections. In the present study, we investigated whether a mangrove plant, Bruguiera gymnorhiza (L.) Lam. (B. gymnorhiza) collected in Mauritius, possesses antimicrobial and antibiotic potentiating abilities and exerts anti-ZIKV activity at non-cytotoxic doses. Microorganisms Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 70603, methicillin-resistant Staphylococcus aureus ATCC 43300 (MRSA), Salmonella enteritidis ATCC 13076, Sarcina lutea ATCC 9341, Proteus mirabilis ATCC 25933, Bacillus cereus ATCC 11778 and Candida albicans ATCC 26555 were used to evaluate the antimicrobial properties. Ciprofloxacin, chloramphenicol and streptomycin antibiotics were used for assessing antibiotic potentiating activity. ZIKVMC-MR766NIID (ZIKVGFP) was used for assessing anti-ZIKV activity. In silico docking (Autodock 4) and ADME (SwissADME) analyses were performed on collected data. Antimicrobial results revealed that Bruguiera twig ethyl acetate (BTE) was the most potent extract inhibiting the growth of all nine microbes tested, with minimum inhibitory concentrations ranging from 0.19-0.39 mg/mL. BTE showed partial synergy effects against MRSA and Pseudomonas aeruginosa when applied in combination with streptomycin and ciprofloxacin, respectively. By using a recombinant ZIKV-expressing reporter GFP protein, we identified both Bruguiera root aqueous and Bruguiera fruit aqueous extracts as potent inhibitors of ZIKV infection in human epithelial A549 cells. The mechanisms by which such extracts prevented ZIKV infection are linked to the inability of the virus to bind to the host cell surface. In silico docking showed that ZIKV E protein, which is involved in cell receptor binding, could be a target for cryptochlorogenic acid, a chemical compound identified in B. gymnorhiza. From ADME results, cryptochlorogenic acid is predicted to be not orally bioavailable because it is too polar. Scientific data collected in this present work can open a new avenue for the development of potential inhibitors from B. gymnorhiza to fight ZIKV and microbial infections in the future.
