Salmonella is a ubiquitous organism of public health importance that causes diarrhea and other systemic disease syndromes. The ecology and epidemiology of the organism in addition to the roles played by wild animals are important in understanding its disease. Relevant published peer-reviewed literature was obtained after imputing the study's keywords into the Google search engine. The publications were thereafter saved for the study. The study revealed the ecology of Salmonella is directly related to its epidemiology. These were found to be either positively or negatively influenced by the living and non-living parts of the environment. Free-ranging and captive wild animals can serve as asymptomatic carriers of Salmonella, therefore, help to maintain the cycle of the disease since wildlife serves as reservoir hosts to over 70% of emerging zoonotic diseases. Cockroaches transmit Salmonella through their feces, and body parts and when ingested by birds and animals. The statistically significant over 83% of Salmonella isolation in lizards suggests the reptile could be a source of Salmonella distribution. Snakes, foxes, badgers, rodents, and raccoons have been reported to have Salmonella as a natural component of their gut with the ability to shed the organism often. The high occurrence (>45%) of diverse Salmonella serovars coupled with the fact that some of these animals were handled, kept as pets and consumed by man portends these animals as potential sources of transmission of the organism and the disease. The etiology and epidemiology of Salmonella are overtly affected by several environmental factors which also determine their survival and maintenance. The roles played by wild animals in the relationship, transmission, growth or interaction within and between Salmonella spp., the occurrence, prevalence, and distribution of the organism help maintain the organism in the environment. An understanding of the roles played by the different parts of the environment and wild animals in the ecology and epidemiology of Salmonella can help make informed decisions on the prevention and control of the diseases it causes. This review aimed to investigate the relationship between ecology, epidemiology, and environment, including the roles played by wild animals in the maintenance of the organism and its disease.

Fruits and vegetables are sources of parasitic infections in humans. This study was designed to determine the epidemiology of parasitic contamination of fruits, vegetables, and water, as well as the perception of retailers, buyers, and consumers about its contamination in Kwara Central, Nigeria. A cross-sectional study design was employed for this study. A total of 160 fruits, 349 vegetables, and 51 water samples were randomly purchased/collected from thirty different markets. The samples were subjected to sedimentation and modified Ziehl-Neelsen staining techniques. All the types of fruits and vegetables sampled were contaminated with one or more parasites. Eleven different species of zoonotic parasites (6 protozoans and 5 helminths) were detected. Entamoeba coli (39.8%) and Strongyloides stercoralis (9.6%) were the most prevalent protozoan and helminth respectively. The prevalence of other protozoan parasites ranged between 21.3% (Entamoeba histolytica) and 2.3% (Balantidium coli), while that of helminths was between 5.7% (Ascaris lumbricoides) and 2.1% (Trichuris trichiura). Source of fruits and vegetables, source of manure for cultivation, the source of water for washing/wetting purpose, market type, washing of fruits and vegetables before display, the presence of children at home and in the market, and knowledge of parasitic contamination were the risk factors associated (P<0.05) with parasitic contamination of fruits and vegetables among sellers. There is a need to educate the general public on the possibilities of parasitic contamination of fruits and vegetables and its public health implications.

Zoonotic diseases accounts for about 75% of emerging infectious disease and can be devastating to both human and animal health globally. A subset of zoonotic diseases is referred to as “neglected zoonotic diseases - NZDs” as they mainly affect poor populations who live in close proximity to domestic or wild animals often in areas where access to health and adequate sanitary facilities are not available. Furthermore, underestimation of the burden of NZD has continually led to its further neglect in least developed countries such as Nigeria. Controlling zoonotic infections including NZDs in animals is crucial in reducing human infections. Veterinarians provides an understanding of the epidemiology of infectious diseases in animal population and are therefore integral for the overall reduction in global burden of NZDs worldwide. Due to the current lack of and in some cases weak involvement of Veterinarians in policy issues related to zoonotic diseases, there is need to elucidate their importance in NZDs control in Nigeria. This review therefore summarises the neglected zoonotic diseases so far documented in Nigeria and also highlight the important role of the Veterinarian in their prevention and control within both human and animal population. Important recommendations to strengthen the role of the public health Veterinarian for sustainable control of NZDs were made.

Aim: This study aimed to assess the level of awareness of rural poultry farmers on vaccination and to detect Newcastle disease virus (NDV) antibody in local birds (LB) and eggs in Kwara State, Nigeria. Materials and Methods: Data on farmers' attitude, knowledge, practices, and experiences on ND mortality were obtained through an interview using a structured cross-sectional checklist. NDV antibodies were detected in sera and egg yolks of local chickens (LC) and guinea fowls (GF) using hemagglutination inhibition test. Results: A total of 83 interviewees, 287 sera and 121 egg yolk extracts, were examined. The study revealed that 98.8% (82/83) of the interviewee had never vaccinated their flock before. 90% of the interviewee had reported high mortality in birds within 1-6 months old, while the major clinical signs were cold (40.4%) and torticollis (30.8%). Evidences of LB exposure to wild-type NDV were confirmed by the detection of NDV antibodies in 20.8% and 0% of LC and GF, respectively. The mortality differences experienced in <1 and 1-6 months old LB could be explained by the presence of maternally-derived NDV antibody (49.6%) in egg yolk. Conclusion: The study showed that LB suffers from NDV as a result of LB keepers' ignorance and neglect by the government. This has limited local investment and subsequent contribution to gross domestic product. This study suggests that the key factors to the prevention of ND remain awareness creation about poultry vaccination, production of affordable vaccines, and availability/accessibility to veterinarian (or trained personnel).

Aim: This study aimed to assess available assay methods for infectious bursal disease (IBD) diagnosis and seromonitoring in local birds. It also sought to know the prevalence of IBD antibodies among local chickens and guinea fowls in Kwara state, North Central Nigeria. Materials and Methods: Sera were obtained from local chickens and guinea fowls and IBD virus (IBDV) antibodies were assayed using enzyme-linked immunosorbent assay (ELISA), indirect hemagglutination (IHA) test, and agar gel immunodiffusion (AGID) test. Results: A total of 265 sera were obtained from local birds during dry and wet seasons. ELISA recorded the highest prevalence of 81.1% (215/265) while IHA and AGID detected IBDV antibodies in 183 (69.1%) and 122 (46%) birds, respectively. Significant differences were established for IBD-positive sera based on the assay method used, bird species, and seasons. Conclusion: This study indicated that ELISA is the most sensitive and reliable assay method while AGID is the least. It also showed that there is a high prevalence of IBDV antibodies among local birds which were not vaccinated, and this implies a high IBDV activity among these bird species in the study area. This may have significant epidemiological implications on the spread of the virus to exotic bird reared in the rural areas on a commercial scale. Thus, this study suggests continuous surveillance, awareness campaign, and advocacy for vaccination of indigenous birds against IBD.

The roles of wildlife in rabies transmission are still underestimated in many parts of the world. In the developed countries, epidemiology of rabies considering wildlife has been well documented. However, in the least developed and developing countries, emphasis has not given on this issue. Human population is increasing all over the world, and new localities are continuously developing. As a result, wildlife territory is decreasing, and the animals are coming in close contact with humans. Besides, many people are keeping wildlife as the sources of their pleasures. Due to the increased interaction among wildlife, domestic animals and human there is need to intensify efforts on mass education and building of awareness on the risks of rabies spreading by the wildlife, and to institute effective preventive measures to control over the disease. In this mini-review, roles of wildlife in epidemiology of rabies has been discussed considering the dynamics of wildlife in relation with associated intrinsic and extrinsic factors. http://doi.org/10.5455/javar.2017.d198 XML PubReader

Objective: Brucellosis is a bacterial zoonotic disease caused by members of the genus Brucella. It causes economic loss and ill health among animals and humans. This study was conducted to determine the prevalence of brucellosis in cattle particularly in White Fulani breed of cattle in Kwara State, Nigeria.
Materials and methods: A total of 120 blood samples were collected randomly from the cattle in Kwara State of Nigeria. Sera were separated from the blood samples. The serum was used for the identification of antibodies against Brucella present in it. Three screening tests namely Bovine Brucella Antibody Test (BBAT; ImmunoCombR), Rose Bengal Plate Test (RBPT) and Serum Agglutination Test (SAT) were used for the identification purpose.
Results: Based on BBAT, 13.3% (n=16/120) cattle were positive for brucellosis. Similary, 14.2% (n=17/120) and 3.3% (n=4/120 cattle were found to be positive for RBPT and SAT, respectively. The affected cattle were mainly of White Fulani breed with few cross-bred.
Conclusion: Results of this study indicates that brucella antibody is circulating in cattle examined in the study area. This calls for urgent public health intervention and routine screening of other domestic animals as well.

Objective: Swine production is one of the most popular and promising livestock production industries in many parts of Nigeria. It prides itself in contributing to the supplementation of the overall national protein intake, gainfully engaging the citizenry in the industry and generating foreign exchange to the nation through export of produce and products. However, the swine production industry in Nigeria faced with religious and cultural constraints as well as several infectious diseases. The objective of this study was to investigate the prevalence of intestinal parasites in swine in the North Central State of Nigeria.
Materials and methods: A total of 920 pigs comprising of 874 (95%) and 46 (5%) foreign and indigenous breed of pigs respectively were investigated in this study. Quantitative Mcmaster egg-counting technique was used for counting eggs of parasites. Semi-structured questionnaires was used to generate demographic data during October 2014 to March 2015.
Results: Fifty five percent pigs were found to be positive for Hyostrogylus rubidus, while Ascaris suum, Trichuris suis and other unidentified eggs were present in 23, 17 and 5% pigs, respectively. ‘Red Stomach Worm’ infection in swine was the highest parasitic burden observed as compared to other parasites. Spreading of infection within sexes had a P value of >0.5.
Conclusion: The prevalence of parasites in pigs obtained in this work is a consequence of improper husbandry measures and irregular veterinary medical intervention.

Objectives: Poultry production in rural areas is considered as an important source of livelihood for most rural communities. The objective of the present study was to investigate the major factors affecting production of rural poultry in three senatorial districts in North Central Nigeria namely Kwara Central, Kwara South and Kwara North. Materials and Methods: The major factors affecting production of rural poultry were investigated using structured questionnaire to gather data on health and management practices between January to December 2014. Results: The socio-economic characteristics of respondents showed that majority of rural poultry farmers are women and illiterate, that sourced fund from their personal savings, relations and friends. The study also showed that seasonal variation and disease significantly influenced poultry production and its marketability. Conclusion: There is the need to put in place enabling environment to encourage commercialization of rural poultry production in Nigeria and globally. http://dx.doi.org/10.5455/javar.2016.c127
