Item Prevalence and antibiotic susceptibility profiles(2016) ISHOLA,O.O; MOSUGU,J.I; ADESOKAN,H.KIntroduction. Food contamination with Listeria monocytogenes is on the increase posing threats to public health with growing trends in food products recalls due to suspected Listeria contamination. Methods. We conducted a cross-sectional study to determine the prevalence and antibiotic susceptibility profiles of Listeria monocytogenes (Lm) among 71 randomly selected poultry farms in Oyo State, Nigeria. A total of 450 samples comprising cloacal swabs (426) and randomly selected dressed chicken meat (24) were cultured for Lm isolation using BrillianceTM Selective Listeria Agar with antibiotics and microbial load count with Nutrient Agar. Further identification was done using microscopic, biochemical characterization and antibiotic sensitivity tests. Data were analysed using bivariate analysis and student t-test. Results. An overall prevalence of 91.8% Lm contamination was obtained comprising 91.5% (390/426) in cloacal swabs and 95.8% (23/24) in meat. The prevalence of Lm in cloacal samples was significantly associated with poultry type (p = 0.008) and breed (p = 0.000. In addition, all the flocks had at least one positive sample yielding 100% flock prevalence. Antibiotic sensitivity test revealed that most of the isolates were resistant to common antibiotics like Ampicillin-cloxacillin and cefuroxime. Conclusions. The results revealed a high level of contamination with Lm in the poultry flock and meat and the observed resistance to most common antibiotics has implications for future disease control as well as public health. There is need to step up routine screening of food animal products for Listeria contamination as well as measures towards reducing such contaminations.Item Prevalence and predictors of risk factors for Brucellosis.(2016) ADESOKAN,H.K; OGUNDIPE,M.A; ALABI,P.IIntroduction. Brucellosis is endemic in Nigeria and risk factors enhancing its transmission are prevalent. Methods. Following serological evidence of brucellosis and isolation of B. abortus from slaughtered cattle in Ibadan, Nigeria, we administered a semi-structured questionnaire to determine the prevalence and predictors of eating and selling bovine gravid uterus among 350 meat handlers from five major meat processing facilities. We conducted key informant interview for five leading traditional healers to document its use. Data were analyzed using Stata 12. Results. The prevalence of eating and selling gravid uterus were 29.7% and 40.3% respectively. Being meat/offal processor (OR=1.9, 95%CI: 1.11-3.3, P = 0.008) and not knowing that eating undercooked contaminated gravid uterus could expose humans to brucellosis (OR=19.5; 95%CI: 5.73-66.03; P = 0.000) were strong predictors of eating gravid uterus. Similarly, being adult (OR = 1.7, 95%CI: 1.08-2.57, P = 0.02) and inadequate knowledge of brucellosis as a preventable disease (OR = 0.03; 95%CI: 0.004-0.27, P = 0.001) predicted selling gravid uterus. Qualitative data from the traditional healers revealed using gravid uterus as special medicinal preparations to hasten parturition in overdue pregnancies, treat infertility and old age diseases in humans. Conclusions. We demonstrated a high prevalence of risk factors for brucellosis transmission, and some meat handlers’ sociodemographic characteristics and brucellosis knowledge-based markers as predictors of these factors. The traditional healers’ practices portend a challenge to the current brucellosis control strategy. These findings provide insights into designing all-inclusive health programmes aimed at controlling brucellosis spread in Nigeria and other similar settings in developing countries.
