methicillin-resistant Staphylococcus aureus (MRSA) emerged as a hospital problem in the 1960’s and has spread from hospitals to the community and to livestock. Livestock-associated MRSA poses an occupational risk to abattoir workers. This study was carried out to determine the prevalence of MRSA colonizing donkeys in Ebonyi State; the prevalence of MRSA in the humans in contact and the risk factors for colonization in the human subjects.
a cross sectional study was conducted in a slaughter slab in Ohaukwu Local Government Area using cluster sampling technique. 195 donkeys and 50 slab workers were selected. Nasal swabs were obtained and cultured to identify Staphylococcal organisms. Antibiotic sensitivity tests using Kirby-Bauer disc diffusion method was carried out on the MRSA positive isolates to determine their resistance profiles. Interviewer administered questionnaires was used to obtain data on risk factors from the human subjects. Data was analyzed using means, standard deviation and proportions as well as chi square test. The criterion for statistical significance was p < 0.5.
four breeds were identified (Idabari, Fari, Duni and Auraki). 144 (73.9%) jennies (female donkeys) and 51 (26.2%) jacks (male donkeys) were sampled. Prevalence of MRSA in donkeys was 79.5%. Breed and sex were not significantly associated with MRSA colonization in donkeys (X2 = 0.150, P = 0.698, X2= 1.136, P = 0.286). Mean age of slaughter slab workers was 32.4 ± 9.7, 72% females and 28% males. Majority (84%) were married. Mean number of years of work at slaughter slab was 7.6 ± 6.6. Majority (82%) did not use any personal protective equipment while at work. The prevalence of MRSA slaughter slab workers was 54%. Donkey MRSA isolates showed multidrug- resistance (100% to ampicillin, bacitracin, oxacillin and cefoxitin; 99% cloxacillin, and mupirocin; 96% vancomycin). Susceptibility to gentamicin was 96%.
the study identified high prevalence of MRSA colonization in donkeys and human contacts and high resistance of donkey MRSA to antimicrobials that are not routinely used in donkeys. Molecular characterization of MRSA at donkey-human interface is recommended to understand the direction of spread of MRSA at this interface.
Nigeria CDC/Nigeria Field Epidemiology and Laboratory Training Programme 2<sup>nd</sup> Annual Scientific Conference (Abuja)
To create a platform for epidemiologists and public health physicians to share their scientific works, NCDC/NFELTP organized the 2nd annual scientific conference with the theme "strengthening one health through field epidemiology training" at Transcorp Hilton Hotel, Abuja, Nigeria from July 5-7, 2017. The objectives of the conference were to provide residents and graduates a forum to share findings from their field activities; provide training opportunity for trainees on scientific communication; provide an opportunity for epidemiological networking as well as create a forum to discuss pertinent public health issues. In attendance were dignitaries from the United States Centers for Disease Control and Prevention (CDC), USAID, WHO, Africa CDC, Ministries Departments and Agencies, University officials and other implementing partners. With the current rise in zoonotic diseases, the conference also featured a two-day pre-conference workshop on One Health which prioritized zoonotic infectious diseases in Nigeria using standardized prioritization methods. A second workshop focused on antimicrobial resistance. There were 38 oral presentations, 60 poster presentations and 2 plenary sessions. The presentations covered various sub-themes ranging from outbreak investigations, case management, health system strengthening, vaccine preventable diseases, communicable diseases and surveillance. The conference featured a National Night and climaxed with awards to outstanding presenters.
