This study evaluated Salmonella spp. detected in broiler chicken carcasses in Zambia. A total of 440 broiler neck skin samples were collected from 6 slaughter houses along the process line after evisceration and tested for Salmonella spp. Eleven samples (2.5%) were positive for Salmonella spp. The suspected isolates were serotyped according to White- Kauffmann-Le Minor scheme and tested for antimicrobial susceptibility using the Sensititre broth microdilution method. Eight serovars of Salmonella enterica were confirmed namely; S. Bolton (2), S. Enteritidis (1), S. Texas (1), S. Liverpool (1), S. Chomeday (1), S. Mbandaka (1), S. Vellore (1), S. Montevideo (1). Two isolates were not typed completely giving results as S. enterica subsp. enterica O:4:Z and Salmonella enterica subsp. enterica O:3,10:Y. Antimicrobial susceptibility showed a 20% multidrug resistance in which S. Vellore and S. Mbandaka were resistant to 5 antimicrobials namely Ampicillin, Ciprofloxacin, Gentamicin, Tetracycline, Trimethoprim. S. Enteritidis, S. Bolton and Salmonella enterica subsp. enterica O:3, 10:Y were resistant to the antimicrobial Colistin. 50% of the strains were susceptible to the antimicrobials tested. This study reported Salmonella spp. in broiler chickens that have not been reported before in Zambia and showed the presence of antimicrobial resistant strains. \u0000 \u0000 Key words: Salmonella serovars, foodborne disease, broiler chicken, antimicrobial resistance.","PeriodicalId":17608,"journal":{"name":"Journal of Veterinary Medicine and Animal Health","volume":"60 1","pages":"85-90"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73687313","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}

So far, test and slaughter is the most feasible method to control the disease but identification of lesions from slaughtered animals does not always coincide with ante-mortem test results. Fifty four animals which were found positive by comparative intradermal tuberculin test (CIDT) or INF-γ release assay or both were slaughtered and post mortem examination (PME) was conducted to identify tuberculous (TB) lesions. The animals were composed of four age groups (≤ 3; 4-6; 7-9 and ≥ 10 years) the two sexes and two breeds (Boran, Boran-Friesian cross). Out of all the slaughtered animals, lesions were detected from 70.3% (38/54) of them. No significant difference was observed among the four age groups and two sexes of both breeds of animals on the level of TB lesion detection. Higher proportion of the lesion was observed by mediastinal (40.4%) followed by bronchial (34.8%), retropharyngeal (17.9%) and lastly miliary form and mesenteric lymph nodes in equal proportion (3.3%). Among the CIDT positive animals, 59.2% of them had lesions. Similarly, 46.2% of INF-γ release assay positive animals had lesions during postmortem examination. Of the total CIDT (+) and INF-γ (-) animals, postmortem lesions were detected from 22.2% of them, and in the vice-versa, of the CIDT (-) and INF-γ (+) animals, 9.2% of them contain TB lesions. Using the PME as reference test, sensitivity of CIDT was 84.2% and the specificity was 6.2%. Similarly, the sensitivity and specificity of the INF-γ release assay was 65.7 and 37.5% respectively. It is concluded that, both tests predict the development of TB lesions. However, in our condition, CIDT was found more predictable for detection of TB lesions as compared to INF-γ release assay. \u0000 \u0000 Key words: Bovine tuberculosis (BTB), comparative intradermal tuberculin test (CIDT), interferon gamma (INF-γ) release, post mortem examination (PME), tuberculous (TB) lesion","PeriodicalId":17608,"journal":{"name":"Journal of Veterinary Medicine and Animal Health","volume":"36 1","pages":"78-84"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88537010","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}

Semi structured questionnaires were administered to the workers and also observational studies on facilities and sanitary practices in the abattoir were conducted. The results showed that 75.00% of the abattoir workers were between the ages of 25 to 35 years, with majority (P<0.05) not well educated. Also 60.00% of the workers are working in the abattoir for more than 6 years (P<0.05), with only 40.00% were well trained on abattoir operations. Observational assessment of abattoir facilities revealed that the size and sitting of the abattoir were very satisfactory, however not cited close to livestock market. Facilities such as lairage, evisceration section, guttery and tripery section, cold room, detained meat section and condemned meat section are present but non-functional. There is ample supply of water from the overhead tank and also hand pump borehole. Most of the solid wastes (bones, horns and undigested ingesta) were packed in sacks and transported out of the abattoir for other uses, while the rests were burnt in the abattoir and the ashes packed for other uses. Liquid wastes was normally done manually by sweeping with brooms and directed into the drainage system which was opened into the nearby stream and bush. All blood from the slaughtered animals were collected into containers, boiled and taken out of the abattoir for other uses. Cleaning and disinfection of the slaughter slabs, premises and floors were done daily and the wastewater and its effluents directed into drainage. The study recommends renovation of some facilities; provision of sanitary sections with well-equipped facilities and provision of bins and dumpsites for proper disposal of wastes. \u0000 \u0000 Key words: assessment, operational facilities, sanitary practices, solid and liquid wastes, Zagon Shanu abattoir.","PeriodicalId":17608,"journal":{"name":"Journal of Veterinary Medicine and Animal Health","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84390250","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 evaluated the genetic characteristics of Newcastle disease viruses (NDVs) obtained from backyard commercial poultry farms and live bird markets during active and passive surveillance in different regions of Plateau and Nasarawa States of Nigeria between 2009 and 2017. The partial fusion (F) gene coding sequence and cleavage site of five NDV isolates was determined. This was aligned and compared with sequences of representative NDV from the GenBank. Deduced amino acid sequence of the protein revealed that four isolates had virulent motifs (112RRQKRF117) while one had an avirulent motif (112GRQGRL117). One virulent strain was recovered from an apparently healthy duck. Phylogenetic analysis based on comparison with different classes of NDVs revealed that two isolates clustered with genotype XIVb NDVs, another two isolates clustered with genotype XVIIa while one isolate clustered with genotype II. The phylogenetic analysis revealed that the velogenic isolates clustered with published class II genotype XIVb and XVIIa closely related to isolates from Benin and Niger republic. This highlights the need for ND control programmes to place more stringent measures on cross-border trade of live bird and poultry products to prevent the introduction of new strains of NDV that would be more difficult to control. \u0000 \u0000 Key words: Chickens, duck, live bird market, Newcastle disease virus, genotypes, Nigeria.","PeriodicalId":17608,"journal":{"name":"Journal of Veterinary Medicine and Animal Health","volume":"3 1","pages":"20-26"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89256851","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}

At this sight, Ovopet®, an innovative ingredient from eggshell membrane that ensures the supply of nutrients necessary for the repair of joints together with anti-inflammatory compounds of natural origin, appears as a natural alternative supplementation for the treatment of joint problems in horses. Thus the aim of this study was to evaluate the effects of oral supplementation with Ovopet® (eggshell membrane) in trotting horses with mild joint disease during the competing period to assess changes in some locomotor and physiological markers. Twenty French trotters positively identified as irregular or slightly lame were recruited and randomly assigned to either placebo or treatment group. The evaluations were done at days 0 and day 60 after the beginning of the treatment. The lameness, measured by the Equinosis® Q with Lameness Locator® was improved at low and medium speed in the horses intaking Ovopet® while it was kept stable or worsened in the placebo group. The improvement in lameness could be related to a decline in pain in the treated group.  Similarly, the minimum, mean and maximum heart rate were lower at day 60 compared to day 0 in Ovopet® group. The heart rate variability whereas, was higher in Ovopet® compared to placebo. Lower heart rate variability is associated with increased pain.
