A community action network-based intervention for improving knowledge of zoonoses among wildlife hunters and traders in Epe, Lagos, Nigeria.

The West Africa One Health project is a multi-country project designed to utilise the One Health approach and deploy the Community Action Networks (CAN), a concept rooted in the principles of community-based participatory research, to improve knowledge of high-risk communities on zoonoses. The majority of emerging zoonoses occur at the human-wildlife interface, of which wildlife hunters and traders are critical stakeholders. We assessed the effectiveness of a CAN-based intervention involving the use of a video documentary and case studies as model tools in improving the knowledge of zoonoses among wildlife hunters and traders in Epe, an established hunting community in Lagos State, Nigeria.

Seroprevalence of brucellosis and Q fever infections amongst pastoralists and their cattle herds in Sokoto State, Nigeria.

Brucellosis and Q fever are neglected zoonoses of global health importance, with unknown true prevalence in occupationally vulnerable settings, partly due to misdiagnosis for other febrile conditions and poor access to primary health care. We examined the seroprevalence of these diseases and associated factors amongst pastoralists and their cattle in Sokoto State, a hub of cattle and pastoral populations in Nigeria. Serum samples randomly collected from 137 pastoralists and 366 cattle from 27 herds in three selected Local Government Areas (LGAs) in the state were analysed for antibodies to Brucella abortus using Rose Bengal Plate Test (RBT) and competitive Enzyme-Linked Immunosorbent Assay (cELISA) as well as antibodies to Coxiella burnetti using indirect ELISA.

Food Safety Training Is Associated with Improved Knowledge and Behaviours among Foodservice Establishments' Workers.

Though several studies have evaluated the association between food safety training and behavior, little has investigated different training components in association with food handlers' performance. Foodservice workers (N = 211) with at least two years' experience were willing to participate and were selected from major foodservice establishments in Ibadan, southwestern Nigeria, and completed a survey to evaluate the association between training, training area, duration, and refresher training and food safety knowledge and practices. We observed an association between training and knowledge (P = 0.

Pattern of antimicrobial usage in livestock animals in south-western Nigeria: The need for alternative plans.

Resistance to antibiotics has continued to increase, placing future animal and human disease management in real danger. The developing countries characterised by widespread indiscriminate antibiotic use and in which 'third-generation' antibiotics are not readily available or affordable are the worst affected. A 3-year (2010-2012) retrospective survey of antibiotic usage in livestock production in three selected states of south-western Nigeria was conducted.

Safe meat-handling knowledge, attitudes and practices of private and government meat processing plants' workers: implications for future policy.

Introduction: Food-borne disease outbreaks remain a major global health challenge and cross-contamination from raw meat due to poor handling is a major cause in developing countries. Adequate knowledge of meat handlers is important in limiting these outbreaks. This study evaluated and compared the safe meat-handling knowledge, attitudes and practices (KAP) of private (PMPP) and government meat processing plants' (GMPP) workers in south-western Nigeria.

Molecular characterization of Mycobacterium bovis in slaughtered cattle in North-Central Nigeria and the public health implications.

Background: The molecular biological techniques of polymerase chain reaction (PCR) are accurate and rapid diagnostic methods in the epidemiology of Mycobacterium species in humans and animals, especially in developing countries.

Methods: In this study, positive cultures from suspected tuberculous lesions of slaughtered cattle from two abattoirs in north-central Nigeria were subjected to a two-step multiplex PCR technique, based on genus typing and genomic regions of difference (RD).

Results: Out of 50 suspected tuberculous lesions cultured, 40 isolates were obtained.

Mycobacterium africanum and nontuberculous mycobacteria from fresh milk of pastoral cattle and soft cheese in Oyo State--implications for public health.

Background: Milk and.milk products from cattle in tuberculosis endemic countries like Nigeria where pasteurization is not enforced could be a source of health concerns to the consumers.

Methods: We assessed randomly selected fresh milk from pastoral cattle, cheese samples and sour milk (nono) for the presence of Mycobacterium species through cultural isolation, Multiplex Polymerase Chain Reaction (PCR) and PCR-restriction enzyme analysis (PRA)-hsp65.

Seroprevalence and risk factors of brucellosis in goats in selected states in Nigeria and the public health implications.

Available reports on brucellosis in Nigeria are largely confined to cattle while it is believed that other ruminants like sheep and goats are equally exposed to the disease. To have an insight into the role of goats in the epidemiology of brucellosis in Nigeria, we conducted a cross-sectional study between June 2011 and May 2013 to determine the seroprevalence of brucellosis in goats in some selected states in Nigeria. Serum samples were collected from goats at different locations and tested for antibodies to spp using the Rose Bengal Test (RBT), samples positive by RBT were further subjected to Competitive Enzyme Linked Immunosorbent Assay (cELISA).

Prevalence of previously undetected tuberculosis and underlying risk factors for transmission in a prison setting in Ibadan, south-western Nigeria.

People with congregational tendencies such as the prison inmates constitute an important target group in the global efforts towards the control of tuberculosis (TB). The prison setting in most developing countries particularly Nigeria, currently does not have routine diagnostic procedures for TB despite the existing risks that could facilitate disease transmission. We conducted a cross sectional study among the inmates in a major prison in south-western Nigeria for TB by screening their sputum samples using a simple random sampling method coupled with questionnaire interview, on the assumption of sub-clinical pulmonary TB infection.

Knowledge, attitudes and practices of traceability among livestock traders in south-western Nigeria: implications for sustainable livestock industry.

Livestock diseases and other animal health events are a threat to achieving sustainable livestock industry. The knowledge of trace-back and the practice of providing feedback on diseases encountered in slaughtered animals from the abattoir to the farm can help limit the spread as well as manage potential future incidents of such diseases. We assessed the knowledge, attitudes and practices of 200 willing livestock traders on traceability in Bodija Municipal Abattoir, south-western Nigeria.
