A total of 120 samples were collected during twice visits per week for 10 weeks including; 40 meat samples of slaughtered sheep, 20 swabs from equipment, 20 water samples, 20 surface swabs (floor and wall swabs) beside 20 hand swabs from slaughterhouse workers. Samples were subjected to bacteriological assessment via determination of aerobic plate count, Enterobacteriaceae count and coliforms count beside isolation of some potential pathogenic bacteria. The recorded results clarified the mean value of aerobic plate count was 9.9 × 106, 9.1 × 106, 4.1 × 106, 9.5 × 108 and 1.5 × 105 cfu/g for the examined samples of meat, equipment, surfaces, water and workers, respectively while the mean value of Enterobacteriaceae count was 0.5 × 102, 1.0 × 102, 3.3 × 102, 1.1 × 102 and 2.5× 103 cfu/g for the examined samples of meat, equipment, surfaces, water and workers, respectively and the mean value of Enterobacteriaceae count was 3.4 × 103, 3.5 × 103, 4.3 × 104, 2.4 × 103 and 2.5× 102 cfu/g for the examined samples of meat, equipment, surfaces, water and workers, respectively. In conclusion, to avoid high bacterial load of meat, application of the HACCP system during abattoirs work, educational programs must be applied to the workers as learning of such workers about sources of contamination of meat and personal hygiene to avoid cross contamination.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124317433","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}

Another apparently healthy five puppies within similar age range were enrolled as healthy control group. Up on admission, clinical signs were recorded and rapid in-clinic IC test kit for detection of CPV Ag in feces. Blood samples were used to determine haemato-biochemical alterations along with Acute phase response values. Vomiting and foulsmelling bloody diarrhea with marked dehydration were the main recorded clinical signs. Hemogram of CPV infected dogs, revealed the presence of microcytic hypochromic anemia, significant leukopenia with marked lymphopenia and neutropenia.

Avibacterium paragallinarum (A. paragallinarum) causes an important respiratory disease in chicken known as infectious coryza which is characterized by low feed conversion ratio, drop in egg production and less marketability. This study aimed at isolation, and identification of A. paragallinarum from chicken of different ages at different localities in Sharkia Governorate, Egypt using different diagnostic methods including ELISA, bacteriological culture, and PCR. Furthermore, antimicrobial resistance profiling of the recovered A. paragallinarum isolates was screened using the disk diffusion method. The obtained results in the present study revealed isolation and identification of A. paragallinarum from chicken with coryza-like symptoms from different localities in Sharkia Governorate, Egypt. PCR screening of A. paragallinarum-specific 16S ribosomal RNA revealed that 12 (24%) of the coryza-suspected cases were confirmed to be caused by A. paragallinarum. Samples from Menia-Alkamh had the highest prevalence rate (6%) of A. paragallinarum, while that originated from Belbies city had the lowest prevalence rate at 2%. Conjunctiva had the highest prevalence among the examined tissues. Recovered A. paragallinarum isolates showed multidrug resistance profiling with high sensitivity to neomycin and gentamicin. In conclusion, combination of ELISA, bacteriological culture, and PCR is highly recommended for an accurate diagnosis of infectious coryza in chickens. The use of neomycin, and gentamicin is highly suggested in the control of infectious coryza in chickens.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122451413","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}

Additionally, 80%, 55%, 50%, and 25% of the examined kariesh cheese, raw liver, raw milk, and raw meat, respectively exceeded Egyptian limits of S. aureus in meat and dairies. Besides, S. aureus isolates showed clear multidrug resistance profiling. PCR testing of selected S. aureus isolates for harboring Staphylococcal enterotoxin-coding genes revealed that none of the tested genes were detected in isolates recovered from raw meat.

NZW rabbits were housed in wire cages (45 cm x 45 cm x35 cm) in groups of 2 rabbits cage-1 (low stocking density; LSD) and 4 rabbits cage-1 (high stocking density; HSD). For the two densities, NZW rabbits were fed three diets with variable OEO levels and experimentally infested with P. cuniculi for 7 weeks by the following manner, (T1) group was the control group that has 0.0 OEO level kg-1 diet without mite infestations, (T2) and (T3) group were supplemented with 200 mg OEO kg-1 diet but only (T3) group was experimentally infested with mites, while the last treatment (T4) was experimentally infested with mites and supplemented with 400 mg OEO kg-1 diet. Finally, the current study found that a low dose of OEO-based feed had a favorable influence on the growth performance of NZW rabbits kept at LSD, with apparent benefits on antioxidant defense and innate immunity status. Our results also revealed that feed conversion ratio in rabbits provided with phytogenic supplemented diets had significantly lower values than in rabbits fed other treatments, indicating that phytogenics can promote growth. As a result, the practical consequences of phytogenic inclusion in rabbit feeds include the potential to improve rabbit growth performance and feed utilization. This would allow for faster rabbit growth, which would result in increased production time at optimal density while avoiding rabbits' parasitic infestations with mite. In conclusion, the findings of this study revealed that adding OEO in a dose of 200 mg kg-1 diet enhanced feed utilisation, rabbit somatic growth and ameliorating intensification and mite infestation stress effects on NZW rabbits.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123471781","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 total number of nineteen (n=90), non-pregnant crossbreed dairy cows, 40-days postpartum were included in this study. Cows were examined using ultrasonographic examination to ensure absence of any uterine affections. Five cows were excluded due to uterine affections during examination. Estrus synchronization using GnRH, PGF2α and GnRH (GPG) regimen were applied however, another 10 cows were excluded due to showing an estrus signs after the first GnRH injection. The timed artificial insemination (AI) were applied to other cows blindly at the 10th Day of the protocol. Rectal ultrasonographic examination were applied at beginning of the synchronization, then at the 9th day of the protocol (at the second injection of GnRH). For pregnancy diagnosis, ultrasonographic examination were performed at the 20, 25, 30, 40, 50, 60, 70, 80 and 90th day after AI in all cows.
