A resurgence occurred on the 25 th of May, 2021. This study gives focused case report of fresh outbreaks of HPAI in Lagos state, south-western Nigeria. Investigation revealed that there were seventy four (74) epidemiologically linked outbreaks in six (6) locations: - Aiyedoto and Ojo military cantonment (Amuwo-odofin LGA), Ajah (Eti-osa LGA), Ago palace Okota (Isolo LGA), Oke-Oshodi (Epe LGA) and Badagry (Badagry LGA). Intensively managed, adult laying birds kept in clusters of less than 10 meters apart in Aiyedoto poultry farm settlement were predominantly affected. Disease prevalence was 15.7%. Incidence rate of infection was 0.2 per hundred bird-days at risk, associated mortality rate was 67 per x103 birds. Real time PCR revealed HPAI H5N1. Stamping out of the entire bird population in affected areas was done. Barely a year after the 2021 outbreaks were curtailed, on the 16th of October, 2022 another outbreak was reported from Agricultural Youth Empowerment Scheme (AGRIC YES) poultry farm settlement. The outbreak at this time was reported in 5 locations: - Aiyedoto and Ojo military cantonment (Amuwo-odofin LGA), Araga (Epe LGA), Awoyaya Ibeju and Lekki (Ibeju-Lekki LGA). In all there were 16 outbreaks. Policy review regarding siting and spacing of poultry farm premises in addition to inter- and intra-state movement of birds is inevitable to control disease spread and reduce associated public health risk.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135585553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there has been conflicting reports of its long-term effects on the male reproductive organs. In this study, the effect of varying doses of methanol extract of GK on testicular function and structure in Wistar rats was evaluated. Forty adult male rats (350-360g) were randomly divided into 4 groups. Groups 1, 2 and 3 received oral doses of 600mg/kg, 400mg/kg and 100mg/kg of the extract daily, respectively for 70 days while group 4 (control group) received normal saline (0.9% NaCl). Blood samples were collected fortnightly from each rat for serum chemistry and testosterone analysis. At termination, the testes, epididymides and livers were harvested, weighed and fixed in 10% neutral buffered formalin and processed for histopathology. The results were presented as mean ± standard error of mean (SEM) and analyzed using one way analysis of variance (ANOVA) at P< 0.05. Dose-related pathological changes were observed in the testes and epididymides. Testicular weight decreased significantly (p<0.05) in 400mg/kg and 600mg/kg groups compared to the control group. There was testicular necrosis associated with distortion of the seminiferous tubular wall and reduced seminiferous tubular diameter. Seminiferous tubules had reduced germinal epithelial thickness along with an absence of viable spermatids and spermatozoa. Serum testosterone levels decreased progressively (p < 0.01) in groups 1 and 2 while those of groups 3 and 4 remain unchanged. The results established that ingestion of methanol extracts of GK seed at the dose of 400mg/kg and 600mg/kg produced significant gonadal pathology in adult male Wistar rats despite the absence of remarkable hepatic biochemical and structural changes.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135580124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aspergillosis, a fungal infection in chicks often occurs in the first 2 weeks of life and may be misdiagnosed as a common respiratory problem like Mycoplasmosis. Some Veterinarians are of the opinion that there is no effective way of treating Aspergillosis. This clinical case report describes the management of acute aspergillosis in chicks. Necropsies were done thrice. Grossly, congested livers, hemorrhagic nephritis, and congested lungs with whitish nodules were observed. Histologically, there were numerous multinuclear giant cells, macrophages and heterophils in the liver. The lung showed fungal hyphae and inflammatory cells. In the kidney, there was severe tubular epithelial necrosis indicated by the pyknotic nuclei, mononuclear infiltrates and haemorrhages. Considering the mortality rate, necropsy findings, microbial isolation and histopathologic observations, systemic Aspergillosis was diagnosed. The secondary bacterial infection was caused by Escherichia coli which was resistant to 8 antibiotics and susceptible only to Penstrep® (Penicillin +streptomycin). Initial resistance to copper sulphate necessitated a change to Nystatin which was used for 12 days via drinking water. Cumulative mortality was 757 (34.37%) in a flock of 2,202 chicks. Better control of systemic fungal infections may be enhanced by early application of anti-fungal susceptibility test.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135585556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this prospective cross-sectional study was to document measurement indices used for the evaluation of canine thoracic silhouette. Thirty healthy Nigerian Indigenous Dogs, 10 puppies and 20 adults of average body weight 8.19±2.45 kg and comprising equal number of both sexes. Ninety survey dorsoventral, right lateral and left lateral thoracic radiographs of the animals were obtained. The shape of the thoracic silhouette in each radiograph was objectively evaluated and adequately described. In the right and left lateral views, sternovertebral distance and sagittal vertebral diameter of the tenth vertebra were measured and recorded; while the dimension measured in the dorsoventral view was costocostal distance. In the lateral radiographs, mean values of vertebral indices (VI) for right/left lateral radiographs were 0.10±0.00/0.10±0.00, respectively. Results of normal thoracic silhouette determined in dorsoventral versus right lateral orthogonal radiographs were: frontosagittal index (FSI) 1.06±0.05 and Haller index (HI) 0.95±0.04.

Twentyfive grams each of raw fish gut and skin were collected from 800 raw fish sold in 8 major markets randomly selected from the study area. Isolation of Listeria was done using half and full fraser broths, and polymyxin acriflavine lithium chloride ceftazidime aesculin mannitol (PALCAM) agar. Confirmation of the genus Listeria was done by a polymerase chain reaction. Identification of species was done using an analytic profile index (API) kit specific for Listeria. The antibiotic resistance of the isolates was determined using disc diffusion method. Out of the 800 fish samples, 38 (4.75%) were positive for Listeria species. Enugu North (6.50%) had significantly (P<0.05) higher prevalence than Enugu East (3.0%). Five Listeria species were identified. Listeria innocua (71.1%) predominated, followed by Listeria welshimeri (10.5%), Listeria ivanovii (7.9%), Listeria grayi (5.3%) and Listeria monocytogenes (5.3%). All the isolates were susceptible to the tested antibacterial agents. The occurrence of Listeria species in raw frozen Atlantic mackerel fish, poses a threat, when consumed raw or lightly cooked, to people especially the immunocomprormised persons whose population is increasing as a result of improvement in medical technology. Also, the possibility of cross contamination in the kitchen or food service establishments is also a concern. Since all the Listeria species got in this study showed 100% susceptibility to all the antimicrobials tested, therefore, there is no fear of acquiring and transferring antibiotic resistance genes from raw frozen Atlantic mackerel fish to the general human population.

Foot-and-mouth disease (FMD) has been a highly contagious viral disease of agricultural importance in domestic ruminants and pigs, hampering livestock productivity in countries where the disease is still endemic. The study aimed to determine the swine FMD occurrence in order to elucidate the disease burden within Federal Capital Territory, Abuja and its environs. One hundred (100) sera were collected from Pigs and subjected to 3ABC ELISA test at the FMD Laboratory in National Veterinary Research Institute (NVRI), Vom. The result showed that out of 100 sera samples tested for FMD antibodies, 26 (26%) were positive and 74 (74%) were negative. Sero-positive distribution showed sow/gilt (32.7%), younger pigs (57.7%) and local breeds (50%) were more exposed to FMD. Although, this was not significant (P>0.05). Questionnaire report further showed knowledge attitude and practice (KAP) of farmers was good, however, the absence of vaccination could be a contributing factor to FMD spread to other susceptible and between carrier livestock within the study area. This finding suggests an increasing occurrence of FMD in pigs within the Guinea Savanna Zone of North-Central Nigeria.
