The death toll and economic loss resulting from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic are stark reminders that we vulnerable to zoonotic viral threats. Strategies needed identify characterize animal viruses pose greatest risk of spillover spread in humans inform public health interventions. Using expert opinion scientific evidence, identified host, viral, environmental factors contributing virus humans. We then developed a ranking framework interactive web...
The use of antibiotics in food animals and the nonobservance withdrawal period might result accumulation persistence residues foods. contamination foods by antibiotic induce health risks including allergy, gastrointestinal dysbiosis, antimicrobial resistance, cancer to consumers. Therefore, this study was initiated investigate presence raw eggs, milk, beef collected at wholesale retail points three major cities Cameroon consumers' perceptions risk Qualitative residue kits (PremiTest®...
In low- and middle-income countries, data on antimicrobial use (AMU) resistance (AMR) in aquaculture are scarce. Therefore, summarizing documented AMU, residue (AR), AMR Africa is key to understanding the risk public health. Google Scholar, PubMed, African Journals online, Medline were searched for articles published English French following PRISMA guidelines. A structured search string was used with strict inclusion exclusion criteria retrieve screen articles. The pooled prevalence 95%...
A cross-sectional seroprevalence study was conducted on cattle in the North and Adamawa Regions of Cameroon to investigate status bovine brucellosis identify potential risk factors. The diagnosis carried out using Rose Bengal Plate test (RBPT) indirect ELISA (i-ELISA), while questionnaires were used evaluate factors for cattle. Bayesian approach diagnostic tests’ sensitivity specificity. overall individual level (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
We conducted a pilot study to assess microbiological safety of chicken litter, an affordable organic and main fertilizer used in Cameroon worldwide. A convenience sampling 26 farms was done questionnaire administered. Samples litter were aseptically collected. E. coli Salmonella spp. isolated using CLSI standards. Antibiotic susceptibility testing performed the disc diffusion method micro broth dilution for colistin. In broiler farms, 90% participating farmers gave antibiotic prophylaxis....
Abstract Monkeypox virus (MPXV) is a reemerging of global concern. An outbreak clade I MPXV affected 20 captive chimpanzees in Cameroon 2016. We describe the epidemiology, virology, phylogenetics, and clinical progression this outbreak. Clinical signs included exanthema, facial swelling, perilaryngeal eschar. Mpox can be lethal chimpanzees, with death likely resulting from respiratory complications. advise avoiding anesthesia animals to reduce likelihood death. This presented risk animal...
Brucellosis is a neglected debilitating zoonosis with high prevalence in many developing countries. Bovine brucellosis widespread Cameroon but the epidemiological situation of human not known. A cross sectional study was carried to determine seroprevalence and factors associated bovine among abattoir personnel pregnant women Ngaoundéré, Cameroon. Serum sample from 590 cattle 816 plausible occupational risk vulnerable humans (107 709 women) were collected screened for anti-brucella antibodies...
Behavioral practices are one of the key factors facilitating zoonotic disease transmission, especially in individuals who have frequent contact with wild animals, yet those work and live high-risk animal-human interfaces, such as animal 'bushmeat' markets Congo Basin not well documented social, health medical sciences. This region, where hunting, butchering, consumption meat is frequent, represents a hotspot for emergence, has experienced spillover events, traced back to close human-animal...
Abstract In an effort to strengthen global capacity prevent, detect, and control infectious diseases in animals people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, local One Health capacities early disease detection, rapid response, control, risk reduction. From outset, EPT approach was inclusive social science research methods designed understand contexts behaviors communities...
Ten herd-level cross-sectional studies were conducted in peri-urban dairy production areas of seven West and Central African countries (Burkina Faso, Burundi, Cameroon, Mali, Niger, Senegal Togo). The objectives to estimate herd level Brucella spp. seroprevalence identify risk factors for seropositivity. In each the ten study areas, herds (between 52 142 per area, total = 965) selected probabilistically a structured questionnaire was administered gather information on their structure...
Antimicrobial consumption surveillance is a useful tool for planning antimicrobial resistance control strategies and risk analysis. The present study was carried out to evaluate the trends of antimicrobials veterinary use in food-producing animals Cameroon from 2014 2019. Data on quantities classes active substances were collected records technical authorization import drugs suppliers' invoices at Ministry Livestock (MINEPIA); animal population data FAO-Stat database. revealed that 217.67...
Residues of antimicrobials used in farm can exert selective pressure and accelerate the occurrence multidrug resistant bacteria litter. This study aimed to investigate resistance profile Escherichia coli isolated from poultry A total 101 E. strains was 229 litter samples collected stored for two months laboratory at room temperature. Antimicrobial susceptibility testing performed using disk diffusion method. An overall prevalence 58.4% (95% CI: 48.8–68.0) obtained with 59 various...
Abstract Host-virus associations have co-evolved under ecological and evolutionary selection pressures that shape cross-species transmission spillover to humans. Observed virus-host provide relevant context for newly discovered wildlife viruses assess knowledge gaps in host-range estimate pathways potential human infection. Using models predict networks, we predicted the likelihood of humans as hosts 513 detected by large-scale surveillance at high-risk animal-human interfaces Africa, Asia,...
Sub-Saharan African market is highly affected by counterfeit veterinary drugs. Though these and non-compliance of drugs can induce adverse effects during their utilization, there no monitoring system medicines. The present pilot study was carried out in Cameroon to identify describe suspected cases reactions animals / or humans as well inefficacy methodology involved a descriptive cross-sectional survey 67 actors the medicine sector Cameroon.A total 74/120 (62%) lack efficacy 46 (38%) were...
Zoonotic spillover of animal viruses into human populations is a continuous and increasing public health risk. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) highlights the global impact emergence. Considering history diversity coronaviruses (CoVs), especially in bats, SARS-CoV-2 will likely not be last to from animals populations. We sampled tested wildlife Central African country Cameroon determine which CoVs are circulating how they relate previously detected CoVs. collected...
Adenoviruses (AdVs) are diverse pathogens of humans and animals, with several dozen bat AdVs already identified. Considering that over 100 human known, the huge diversity species, many likely remain undiscovered. To learn more about AdV prevalence, evolution, we sampled tested bats in Cameroon using PCR assays for viral host DNA. DNA was detected 14 % 671 animals belonging to 37 different species. There a correlation between species roosting larger groups detection. The belonged 28 44...
