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. Agama) were obtained. Salmonella Agama harboured 12 virulence genes, while S. Typhimurium and S. Albany harboured 11 virulence genes each. This study highlights the importance of S. Typhimurium, S. Albany, and S. Agama as major pathogens associated with poultry farms in Ilorin, north-central Nigeria. It equally provided baseline information on the serovar distribution, STs, resistance and the virulence gene profiles of all the serovars. Therefore, chickens can serve as a potential source of Salmonella transmission to humans, and this constitutes a potential health risk to the human population. Hence, there is a need for a specific Salmonella control program to be instituted as part of a national food safety strategy. \u0000 \u0000 \u0000 \u0000","PeriodicalId":253894,"journal":{"name":"Sokoto Journal of Veterinary Sciences","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123604938","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 study was carried out in Idah, Kogi State, Nigeria. A total of 54 households from 6 villages were used for the evaluation. Structured questionnaires on the socio-economic characteristics of the goat owners were administered. Data on the reproductive performance of goats were collected by visual appraisal. The data collected were on herd size, sex, number of pregnant goats, lactating goats and newly weaned kids. The result showed that more women (63.6%) were involved in goat rearing than males (36.4%), and about 91.6% of the respondents had a herd size of 1-20 goats, while only 8.4% had a herd size of 21-30. The goat herd distribution showed that the average herd size was 16.5goats, within the range of 7 to 30 goats. The herd structure was 391 females and 184 males. Three breeds of goats were identified, the West African Dwarf (WAD) goats being the dominant (397), followed by Maradi (Red Sokoto) breed (113), and the least was Pygmy breed (75). Season significantly influenced pregnancy and the number of lactating goats. There were more lactating goats during the cold-wet period and more pregnant goats during the hot-dry season. It was concluded that goat production is still at the peasant level, and goats were kept as a supplementary source of income. The conception rate was high during the cold-dry season, which was manifested in the hot-dry season. More awareness is still needed to increase the production of goats in the area.

The objectives of this study are to determine the serovar distributions, genomic antimicrobial resistance, prediction of genes conferring resistance to selected antibiotics, the multi-locus sequence typing (MLST), and plasmid replicon typing of “unassigned” S. enterica isolated from poultry. A total of 300 samples comprised of: post-mortem tissues (n = 150), cloacal swabs (n = 30), and poultry environment (n = 120) were aseptically collected and analyzed between January and June, 2017. Presumptive S. enterica isolates were characterized using conventional cultural methods, biochemical tests, and serotyping. The isolates were characterized, using Whole Genome Sequencing (WGS) Method. Five “unassigned” S. enterica serovars were recovered from four matrices (liver, n = 1; water, n = 1; cloacal swab, n = 2; poultry feed, n = 1). Prediction of point mutation in parC (T57S) was reported in two strains which confer resistance to nalidixic acid; in addition to this, prediction of fosA7 that confers resistance to fosfomycin was identified in one of these strains. Three isolates each encoded plasmid mediated quinolone resistance (PMQR) qnrB69 and bla-CMY-98 genes expected to confer decreased susceptibility to ciprofloxacin and resistance to ampicillin, amoxicillin-clavulanic acid, cefoxitin, and ceftriaxone, respectively. Three sequence types, ST-6111, 6114 and 7073 were detected. None of the isolates harbored plasmid replicon.

At peak parasitaemia (8 days post-infection), group III was treated with diminazene aceturate (3.5 mg/kg) intramuscularly once while groups IV, V, VI were treated with artesunate (200, 100, 50) mg/kg orally for 5 consecutive days and group VII was treated with combination of artesunate (50 mg/kg) orally and diminazene aceturate (1.75 mg/kg) intramuscularly for 5 days. Results indicated pre-patent period of 4 days and increase in levels of parasitaemia post-inoculation. PCV, Hb concentration, RBC count, MCV, MCHC and total leucocyte count decreased significantly (p < 0.05) between days 0 and 8 in groups II to VII. Following treatment, significant increases (p < 0.05) were recorded except for groups II, IV, V and VI where the rats died. Thus, combination of artesunate (50 mg/kg) and half the standard dose of diminazene aceturate was able to reduce parasitaemia and ameliorate the anaemia elicited by the trypanosomes.","PeriodicalId":253894,"journal":{"name":"Sokoto Journal of Veterinary Sciences","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127044684","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}
