This study was carried out to determine the seroprevalence and serotypes of swine influenza in pigs from a major slaughter slab in southern Kaduna. Using competitive ELISA and haemagglutination-inhibition (HI) assays, 305 swine sera were analysed. The result showed an overall seroprevalence of 28.20% (n=86), with H3N2 7.87% (n=24) emerging as the most dominant subtype in circulation. Concurrent antibody detection of H1N1 in 5.26% (n=16) was also detected in boar 2.62% (n=8) and sows 2.62% (n=8). This study revealed swine Influenza H1N1 and H3N2 serotypes are in circulation in pigs in Kaduna State, and that reassortment in the instance of co-infection of swine host is possible.","PeriodicalId":253894,"journal":{"name":"Sokoto Journal of Veterinary Sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132995144","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 aim of this study was to determine the status of avian influenza virus (AIV) antibodies in wild birds to provide early warning of an outbreak. One hundred and forty-six sera from five different species of wild birds were tested for antibodies to avian influenza A viruses (H5 and H9) using enzyme linked immunosorbent assay and haemagglutination inhibition (HI) tests. An overall seroprevalence of 3.4% (5/146) was recorded in the study area. Seroprevalence of 6.67% (2/30) was recorded in speckled pigeons (Columba guinea) and Village weavers (Ploceus cucullatus) respectively and 3.33% (1/30) in Cattle egrets (Bubulcus ibis). No antibodies were detected in laughing doves (Spilolepia senegalensis) and African silver bill (Euodice cantans). The serological detection of AIV subtypes H5 and H9 by HI showed the exposure of these birds to the two subtypes. The result from this study indicates evidence of the presence of H5 and H9 AI viruses in wild birds in Zaria, Kaduna State. Therefore, comprehensive surveillance of influenza A involving wild birds’ population and H5 as well as H9 subtype is recommended. This is necessary in order to know the actual status of these strains in the poultry population in Nigeria in view of their zoonotic and economic importance.","PeriodicalId":253894,"journal":{"name":"Sokoto Journal of Veterinary Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120937663","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}

Each diluent was constituted in five aliquots using standard methods and pH determined electronically. Semen collection in three trials using electro-ejaculator method was followed by evaluation for colour, volume, pre-extended sperm motility, concentration, percentage liveability and morphological normality. Thereafter, semen were extended with different diluents by adding 0.2ml of semen to 7.5ml of diluents. Immediately, hourly evaluation for sperm motility from zero to eight hours then twenty-four hours post-extension was done. Diluents revealed in the study as the most effective semen extender were subjected to proximate analyses. The pH of the diluents ranged from 4.56±0.11 (70%M30%C) to 6.40± 0.14 (90%C10%M). The mean ejaculate volume was 0.8±0.00ml while colour observed was creamy.

Six (6) adult autochthonous Nigerian local dogs were used for this study. The dogs were premedicated, intramuscularly, with atropine sulphate and xylazine hydrochloride. They were administered anaesthesia and maintained with Thiopentone sodium intravenously. Access to their abdominal cavity was obtained via a mid-ventral abdominal incision. The large intestine was exteriorized and measured from caecum to rectum. The crown-rump length (CRL) and caecum (C) were significantly longer (p<0.05) in the larger dogs (11–16 kg) compared to the smaller ones (5–10 kg). The colon and rectum (CR), TLIL and the ratio of crown-rump length to intestinal length (CRLT) did not differ significantly (p>0.05) between these two size-wise categories of dogs. The ratios of crown-rump length to weight (CRLW) and large intestinal length to weight (LILW) were significantly higher (p<0.05) in the smaller dogs than in the larger ones. There was a strong correlation between the weight and the CRL (0.53) and between the weight and TLIL (0.66). The average TLIL was 48.3 cm in the larger dogs and 45.1 cm in the smaller ones. The average colon and rectum length was 37.7 cm in the larger dogs and 36.8 cm in the smaller ones. The average C length was 10.2 cm in the larger dogs and 8.3 cm in the smaller ones. The average CRL was 1.5 times the average TLIL in Nigerian local dogs. Conclusion: Body size does not affect the total length of the large intestine of Nigerian local dogs.

Nigeria first reported an outbreak of avian influenza which was caused by subtype H5N1 in 2006, thereafter virological and serological surveys revealed the importance of local birds in live bird markets and the community at large in the epidemiology of avian influenza in the country. In the present study, 276 serum samples were collected for serological testing over five months from apparently healthy local birds in live bird markets within two Local Government Areas of Plateau State, to determine antibody prevalence to avian influenza A virus. The detection of influenza A antibody was carried out using an Enzyme-linked immunosorbent assay and further tested by haemagglutination inhibition to determine the specific serotype of the influenza A virus. The result showed a prevalence of 30.4% (n=84) of antibody to influenza A, 26% (n=72) of serotype H9, 1.4% (n=4) of serotype H7, and none was confirmed to be H5 serotype. Comparatively, Jos-North had a lower relative risk with a prevalence of 18.9% (n=18) to the disease as compared to Jos-South with a prevalence of 36.5% (n=66). This study showed the presence of low pathogenic avian influenza A virus in live bird markets within the study area with the dominance of antibodies to H9. To our knowledge, this is the first serological indication of serotype H9 in Plateau State and Nigeria. Evidence of influenza A/H9 in an ecological niche known for the circulation of subtypes H5Nx may complicate the epidemiology and control of avian influenza in the region and Nigeria at large. The level of awareness by the live bird market operators about avian influenza (AI) was relatively low as indicated by the questionnaire survey conducted. Live bird market operators and poultry farmers need to maintain a high level of biosecurity and limit mixing local birds with commercial poultry to prevent the transmission of the virus which may have adverse effects on poultry production, national and international trade, the economy and public health.","PeriodicalId":253894,"journal":{"name":"Sokoto Journal of Veterinary Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130628504","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 aimed at evaluating the influences of some endogenous factors (breed, sex, age and body mass index; BMI) and season on circulating thyrotropin concentration in Red Sokoto and Sahel goats. A total of 120 goats were sampled, comprising Red Sokoto (n = 20) and Sahel (n = 20) goats in each season during the peak of the cold-dry (CDS), hot-dry (HDS) and rainy (RAS) seasons in a tropical Savannah climate. Results revealed that among Red Sokoto goats, bucks had significantly higher (P<0.05) circulating thyrotropin concentration than does during the HDS, while adults had significantly higher values than kids during the RAS. Significant (P<0.05) breed difference was only observed during the HDS, with the Red Sokoto goats having higher values among adult bucks and doelings but lower values than Sahel goats among buck-kids and adult does. Significant (P<0.05) seasonal variation was observed only in male Sahel goats with buck-kids having lower values during RAS as compared with CDS and HDS, while adult bucks had higher values during the RAS as compared with the HDS. A significant positive correlation (r = 0.29; P<0.001) was observed between thyrotropin concentration and BMI in the overall population. It was concluded that circulating thyrotropin concentration was higher in male and adult goats, and the effects of season and breed were sex and age-dependent. Moreover, the direct relationship between thyrotropin concentration and BMI may reflect the role of thyrotropin in the accumulation of body energy reserve in the savannah goats.","PeriodicalId":253894,"journal":{"name":"Sokoto Journal of Veterinary Sciences","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124365945","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 breed of dog, sex, age on presentation, the limb affected and the radiographic appearance of the lesions on presentation were reviewed. The treatment and clinical management approaches were also reviewed and discussed. Of the cases of avascular necrosis of the femoral head recorded (N = 24) for the period under review, breed prevalence recorded 62.5% (Alsatians); 16.67% (Caucasians) and 20.83% (Mixed Breeds). Sex prevalence recorded 79.17% females and 20.83% males. According to age at the time of the first presentation, 83.83% of the affected dogs were 6-12month old, 12.5% were 13-24month old, and 4.16% were 25–36 month-old. Lameness was observed in 91.67%, while 8.33% of cases presented non-weight bearing lameness. Pain in the limbs during palpation of the hip joint was detected in 100% of the cases.

These samples were subjected to Ziehl Neelsen staining, followed by culture on Lowenstein-Jensen media. Subsequently, polymerase chain reaction (PCR) and sequencing of the 65KDa heat shock protein (hsp65) gene were performed to identify and phylogenetically characterize the cultured organisms. Because sequencing of the hsp65 gene was unable to distinguish between Mycobacterium bovis (M. bovis) and M. tuberculosis, PCR was performed to amplify a genomic region-specific to M. bovis in order to differentiate them from M. tuberculosis. Results showed that, 14 samples yielded growth after culture. Furthermore, hsp65 was detected in 9 out of the 14 isolates screened, 5 of the amplicons were successfully sequenced.

This study investigated the occurrence, serotypes, multilocus sequence types (MLSTs), antimicrobial resistance, plasmids, and 12 selected virulence genes of non-typhoidal Salmonella from poultry layer farms using whole-genome sequencing (WGS) methods. Two hundred cloaca swab samples were aseptically collected from four commercial poultry farms (layers) and transferred in sterile universal bottles on ice to the laboratory for analysis. Presumptive Salmonella isolates were detected with selective media and conventional biochemical tests. Serovars were confirmed by serotyping using the slide agglutination and Seqsero methods. Seven samples were positive for Salmonella consisting of Salmonella Typhimurium (S. Typhimurium) (n = 4), S. Albany (n = 2), and S. Agama with an occurrence rate of 3.5 % (7/200). Overall, 3 isolates showed the parC mutation expected not to cause resistance. Similarly, one S. Typhimurium isolate carried plasmid replicons of IncFIB(S)/IncFII(S) type without antimicrobial resistance genes. Three sequence types (STs); 19 (S. Typhimurium), 5317 (S. Albany), and 467 (S.
