    (Veterinary World, 2018-08) Daodu, Oluwafemi Babatunde; Oludairo, Oladapo Oyedeji; Aiyedun, Julius Olaniyi; Ambali, Hauwa Motunrayo; Kadir, Rafiu Adebisi; Daodu, Oluwakemi Christiana; Olorunshola, Isaac Dayo; Adah, Arimie Deborah
    Abstract 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.

    Awareness and antibody detection of Newcastle disease virus in a neglected society in Nigeria
    (Veterinary World, 2019-01) Daodu, Oluwafemi Babatunde; Aiyedun, Julius Olaniyi; Kadir, Rafiu Adebisi; Ambali, Hauwa Motunrayo; Oludairo, Oladapo Oyedeji; Olorunshola, Isaac Dayo; Daodu, Oluwakemi Christiana; Baba, Saka Saheed
    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).

    (Centre for Peace and Strategics Studies University of Ilorin, Ilorin, 2015) Oludairo, Oladapo Oyedeji; Aiyedun, Julius Olaniyi; Olorunshola, Isaac Dayo
    The possibility of terrorist groups utilizing biological weapons against states and countries is a mounting concern which has increasingly attracted the attention and resources of the world. This study sets out to examine the issue of biological terrorism and its potential threat to public health and national security. This was achieved using baseline information and data generated through related reported studies. Bioterrorism was found to be an ‘entirely possible’, potent, emerging threat to public health, national and international security leading to public health emergency, intimidation of the affected governments and national security vulnerability. Overcoming these challenges calls for the introduction and implementation of new, effective, potent, practical and workable plan and strategies to enhance preparedness, early detection, rapid investigation and quick response in order to stem its devastating effects among human population, animals and environment.

    Gastrointestinal parasites of horses (Equus caballus Linnaeus, 1758) in Kwara and Niger States, North-central Nigeria and the risk factors associated with equine coccidiosis
    (Faculty of Veterinary Medicine, Usmanu Danfodiyo University, Sokoto, Nigeria, 2019) Ola-Fadunsin, Shola David; Daodu, olufemi Babatunde; Hussain, Karimat; Ganiyu, Isau Aremu; Rabiu, Musa; Sanda, Idiat Modupe; Adah, Adole Sylvanus; Adah, Deborah Arime; Aiyedun, Julius Olaniyi
    About two-third of the parasitic infections in animals are believed to occur in the gastrointestinal tract. Coccidiosis is an important disease of horses and it is responsible for a great economic setback worldwide. This study was designed to determine the species diversity and prevalence of gastrointestinal parasites of horses and the risk factors associated with Eimeria infections in horses in Kwara and Niger States, North Central Nigeria. Faecal samples were collected from 105 horses in Kwara and Niger States. Simple floatation and formalin-ethyl acetate concentration techniques were used as diagnostic techniques. An overall prevalence of 62.86% (66/105) was recorded. Eleven gastrointestinal parasites comprising of 7 nematodes, 2 trematodes, 1 protozoan and 1 cestode were detected. Strongylus spp. (33.33%; 35/105) and Eimeria spp. (28.57%; 30/105) were the most prevalent. Forty-six (43.81%) of the sampled population had multiple gastrointestinal parasites infection. Body condition score, presence/ absence of diarrhoea and horse ownership were significantly association with the occurrence of Eimeria infection. This appears to be the first report on gastrointestinal parasites of horses in Kwara and Niger States of Nigeria. The high prevalence reported in this study calls for horse owners to improve on the veterinary medical attention given to their horses as gastrointestinal parasitism is a major cause of economic loss in equine husbandry. The curtailing of gastrointestinal parasitism will improve production, reproduction and performance of horses in the study areas.

    Molecular Detection of invA Virulence and floR Resistance Genes in Salmonella Enterica Isolated From Hawked RTE Roasted/Spiced Meat (Suya) in Ilorin, Nigeria
    (Assiut University, Faculty of Veterinaty Medicine , Egypt, 2026) Oludairo, Oladapo Oladapo; Fabiyi, Fathiat Eniola; Imam, Aisha Anuoluwapo; Balogun, Adedotun Kabirat; Richards, Bukola Arinola; Akpabio, Uduak; Aiyedun, Julius Olaniyi
    Salmonella remains a significant public health concern, particularly in populations where ready-to-eat products, such as roasted/spiced meat (suya), are popular. The consumption of products contaminated with bacteria strains harbouring virulence and resistance genes may result in illnesses such as gastroenteritis, typhoid fever or septicaemia that are tough to control. The invA and florR genes code for cell proteins needed for invasion of the host epithelial cells and antimicrobial resistance to florfenicol (FFC)/chloramphenicol (CM), an antibiotic commonly used in veterinary practice, respectively. This study aimed to detect the presence of invA virulence and floR antimicrobial resistance genes in the Salmonella enterica isolated from 102 Ready to Eat (RTE) suya samples obtained from hawkers within Ilorin, Nigeria, using PCR. The Salmonella strains were sub-cultured, while pure colonies were inoculated into tryptone soya broth, incubated for 24 hours at 37 °C, and transported to the Bioformatics Laboratory, Ibadan, for PCR analysis. DNA was extracted from the isolates and amplified using primers targeting specific parts of the organism’s genome. The PCR products were run on agarose gel electrophoresis and visualized with the gel imagery device. All five (100%) isolates displayed the 284bp invA and 926bp floR genes’ bands. This study confirmed the presence of invasion and antimicrobial resistance genes in all Salmonella enterica from RTE spiced roasted meat obtained from the study area. There is a need for continued surveillance and control measures to prevent foodborne illnesses that may be due to contamination by virulent and antimicrobial-resistant Salmonella in food.

    Neglected zoonotic diseases in Nigeria: role of the public health veterinarian
    (Pan Africa Medical Journal. 32 (36); 1-12, PPan African Medical Center for Public Health Research and Information in collaboration with African Field Epidemiology Network, 2019) Elelu, Nusirat; Aiyedun, Julius Olaniyi; Mohammed, Ibraheem Mohammed; Oludairo, Oladapo Oyedeji; Odetokun, Ismail Ayoade; Kaltume Mamman Mohammed, Kaltume Mohammed; James Olaniyi Bale, James Olaniyi; Nuru, Saka
    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

    Prevalence of intestinal parasitism of swine in a North Central State of Nigeria
    (Bangladesh Agricultural University, Mymensingh, 2016) Aiyedun, Julius Olaniyi; Oludairo, Oladapo Oyedeji
    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.

    (Faculty of Veterinary Medicine Skopje, Macedonia., 2017) Faleke, Olufemi Oludayo; Jolayemi, Kelvin Olatimilehin; Igoh, Yvvone Ogah; Jibril, Abdurrahaman Hassan; Aiyedun, Julius Olaniyi
    This study was carried out to determine Salmonella contamination of food contact surfaces and processing water in meat, fish and poultry processing units in Sokoto State, Nigeria. A total of 200 swab (100 from abattoir and 100 from poultry and fish markets) and 60 processing water samples (30 from abattoir and 30 from poultry and fish markets) were collected between May to August 2015. Cultural isolation, bio-typing and sero-grouping using Salmonella Sero-Quick Group Kit was conducted to analyse the samples. Seventy-five (75/260, 28.8 %) of the total samples were positive to Salmonella by cultural isolation and bio-typing. Thirty (30/130; 23.1 %) of samples collected in abattoir and 45 (45/130; 34.6 %) of those collected from poultry and fish markets were positive for Salmonella respectively. Sero-groups D+Vi (Salmonella Typhi), B (Salmonella Paratyphi B, Salmonella Typhimurium) and C (Salmonella Paratyphi C, Salmonella Cholerae suis) were identified as the prevailing sero-groups in this study. Sero-group D+Vi has the highest prevalence (73.3 %; 55/75) from the positive bio-typing isolates. This study revealed the presence of contaminating and pathogenic Salmonella on food contact surfaces and processing water in the meat retail markets, indicating there is an urgent need to improve on the hygienic status of retail meat, poultry and fish markets.
