Waterfowls and village poultry in live bird markets (LBM) acts as reservoirs, potentially reintroducing the virus to commercial poultry. This study aims at molecular and serological detection of NDV at live bird markets in Plateau State, Nigeria. A cross sectional analysis involved 309 pooled cloacal and tracheal swabs over three months were analyzed by reverse transcriptase polymerase chain reaction (RT-PCR), RT-qPCR, virus isolation and haemagglutination and haemagglutination-inhibition test (HA &HI). Virus isolation was attempted in 9 to 11 days old specific antibody negative (SAN) embryonated chicken eggs and fifteen samples showed haemagglutination. Subsequent tests confimed nine of these as NDV positive through haemagglutination and haemagglutination inhibition (HI) tests. ConventionalRT-PCR and RT-qPCR further validated five of the nine NDV positive isolates. The phylogenetic analysis of partial F gene nucleotide sequences revealed that all three isolates belonged to class II genotype XIV.2_XIVb. This finding underscores the persistent threat of NDV to local poultry, necessitating comprehensive virological surveillance to understand, isolate and characterize the virus in Nigeria. Therefore, monitoring for emerging lineages and sub-lineages in Nigeria birds is crucial for safeguarding commercial poultry production.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"68 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139450247","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}

HMs can be released into the soil, water, and air through industrial, domestic, agricultural run-offs, medical and technological activities. Thirty wild fresh catfish were bought from two major fish markets in Maiduguri (Custom and Monday markets). Zinc (Zn) and Arsenic (As) were determined by Atomic Absorption spectrophotometer. Data obtained were analyzed using descriptivestatistics and independent sample t-tests. The estimated daily intake (EDI) of the metals was calculated, and the target cancer risk (TCR), target hazard quotient (THQ), and hazard index (HI) was derived. The mean concentration (mg/Kg ± SD) of Zn in the liver (0.26 ± 0.32) was higher compared to that in muscle (0.22 ± 0.27), but this was not statistically different (t (58) = 0.608, p = 0.545). However, the mean concentration of As in the liver (0.27 ± 0.33) was lower compared to that in the muscle (0.28 ± 0.23), but this was not statistically different (t (52) = -0.003, p = 0.997). Although, no significant statistical difference, the mean concentration ranking of Zn based on the Fish market was Monday market > custom market, while that of As was custom market > Monday market. EDI values were within tolerable limits. TCR, THQ, and HI values obtained were below the threshold of 1. In conclusion, HMs (Zn and As) were detected in the liver and muscle of all fish samples tested at a lower rate compared to their Maximum Permissible Limits (MPLs) set by the World Health Organization (WHO). However, because of their non-degradable nature and tendency to bio-accumulate in fish tissues and organs, it can be concluded that long-term consumption poses a greater Public Health risk of HMs intoxications in the study area. Therefore, fish consumers should be enlightened more about the harmful effects of HM toxicity by relevant health authorities.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"1 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139450019","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}

This study investigated the sequential histopathogic changes in the lungs, proventriculus, and intestines of broiler chickens infected with velogenic Newcastle disease virus (vNDV). Fifty broiler chickens (6-weeks-old) were randomly assigned into two groups of 25 each: UC – unvaccinated with Newcastle disease (ND) vaccines and intranasallly inoculated with vNDV, UU – unvaccinated uninfected. At 4, 5 and 6 days post-infection (d.p.i) tissue samples were collected from birds in each group for histopathology. The lungs showed hyperaemia, haemorrhages, inflammatory oedema and cellular infiltrations in the secondary bronchi, parabronchi (atria, infundibular, air and blood capillaries of the exchange tissue), depletion of bronchial-asociated lymphoid tissues, loss of cilia and hyperplasia of surface epithelium of bronchi and parabronchi at 4 d.p.i. The lesions progressed to collapsed air capillaries with fibroplasia and fibrosis of the area at 6 d.p.i. Similar inflammatory changes were observed in the proventriculus, but accompanied by degeneration and attenuation of surface epithelium of proventiculus and proventricular glands at 4 d.p.i., and severe necrosis and disintegration of the proventricular glands at 6 d.p.i. The intestine showed severe inflammatory changes in the mucosa, submucosa and serosa and depletion of gut-associated lymphoid tissues at 4 d.p.i., and ulcerative enteritis at 5 d.p.i. The lumen was filled with necrotic debris at 6 d.p.i. This study reinforces the concept making pathologic animal experiments important tools for a complete characterization of strains in susceptible animals, as this information will be helpful in the accurate diagnosis of velogenic Newcastle disease in chickens.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"27 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139449325","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}

A carcass of 4½-year-old White-Fulani was presented to the Necropsy unit of the Department of Veterinary Pathology, Ahmadu Bello University, Zaria for post-mortem examination. Gross findings revealed a shaft of an 18- gauge x 1½inch hypodermic needle within fibrinous tissue extending from the pericardial sac. Other findings include oedema in the jowl and brisket region, ascites, haemothorax, yellow and turbid fluid within the pericardial sac with fibrin flake showing a typical ‘bread and butter’ appearance. Histopathological observation of affected organs showed fibrinous pericarditis with severe fibrin deposition and fibrous tissue proliferation between the cardiac muscle fibres along with infiltration of neutrophils, lymphocytes, plasma cells and hepatic centrilobular necrotic changes. The result of the post-mortem examination revealed that the cow died of traumatic pericarditis. Acute traumatic pericarditis was diagnosed with cardiac tamponade as the possible cause of death. Cattle herders should be familiarized with the causes and symptoms of hardware disease and prompt action to save lives and avoidance of huge economic losses.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"43 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139449414","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}

Male rats weighing between 150 - 200 g age 10-11 weeks old were used. The experiment was divided into 7 groups, which included; Group A distilled water, Group B soya oil at 2 ml/kg, Group C TAU 50mg/kg, Group D TAU 100mg/kg, Group E CYP at 20 mg/kg Group F TAU at 50 mg/kg with CYP at 20 mg/kg and Group G TAU at 100 mg/kg with CYP at 20 mg/kg respectively. The treatments were administered once daily by oral gavage for 60 days. At termination, the rats were decapitated. Sera samples were obtained. The epididymis was separated into head, body and tail, testicular and epididymal filtrate volumes were measured. Paired gonadal and epididymal sperm/spermatid reserves were determined using a haemocytometer and light microscope. Testosterone assay was done with testosterone ELISA Kits. Results showed that testicular sperm/spermatid reserves of groups A and B were 11.50 ± 0.87b x106 /g of testes and 16.00 ± 3.08a x106 /g which were significantly higher than the rest groups (p<0.05). Sperm reserves of the tail epididymis was significantly higher in groups A, B, E and F (p<0.05). The values were 15.75 ± 2.95a x106 /g, 15.25 ± 2.81a x106 /g, 11.50 ± 1.50a x106 /g and 10.0 ± 0.0a x106 /g respectively, Sperm reserves of the head epididymis was significantly higher in groups D and E (p<0.05). The values were 10.25 ± 3.68a x106 /g 9.25 ± 1.89a x106 /g. It was concluded that taurine at 50mg and 100 mg/kg did not show any significant positive effect on serum testosterone, testicular sperm/spermatid reserves, tail and body epididymal sperm reserves. Taurine effect may be dose dependent and influenced by osmoregulation. It was recommended that higher doses of taurine be tested.","PeriodicalId":19330,"journal":{"name":"Nigerian Veterinary Journal","volume":"73 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139450484","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}

We reviewed the anterioposterior and flexed lateral hip radiographs of apparently normal Boerboel dogs presented for hip certification between 2016 and 2022 to determine CHD prevalence in the breed. Radiographs were graded using modified Federation Cynologique International grading system. CHD prevalence was expressed as percentages, while age and sex difference in prevalence of CHD were compared using chi-square test. Relative percentages were calculated for CHD grades C, D, and E. Differences were considered significant at p ? 0.05. Median age for the dogs was 2 years with age ranging between 1 and 6 years. 27 (42.2%) were non dysplastic, while 37(57.8%) were dysplastic. Dogs with grade A accounted mostly for the non-dysplastic dogs, while dogs with grade C accounted mostly for dysplastic dogs.
