Despite treatment with available therapies, many dogs still died from CPV related complications. This study aims to describe the clinical investigation, pathological findings, and molecular diagnosis of canine parvovirus infection in dogs. A total of thirty five samples, including blood and fecal samples were collected from dogs of different ages and breeds (German shepherd, Husky, Loloo, and Rottweiler puppies) to be used in this study. The study considered the dogs' history, clinical examination for vital parameters, alter-ation of haemogram, and fecal examination for detection of canine parvovirus antigen. 10 rectal swabs collected from dogs showing clinical signs of canine parvovirus enteritis were initially tested for CPV-2 using CPV Ag test kits rapid test. Results showed 9/10 of swabs were positive for CPV-2. For further in-vestigations, all swabs were carried out using molecular identification, through the extraction of Viral DNA and conventional PCR for the CPV-2, all samples gave positive results for CPV-2. Histopathological examination of the tongue, lung, kidney and intestine suggested the infection with CPV enteritis. leukopenia, neutropenia, lymphopenia, and thrombocytopenia with a significant increase in monocytic and eosinophilic count were recorded. A significant increase in serum total protein and serum globulin and a significant decrease in serum albumin were noticed. Serum ALT, AST, blood urea nitrogen (BUN), and serum creatinine were significantly increased. Samples that showed strong PCR products were sequenced and phylogenetic analyzed to detect the percentage of nucleotide sequence identity and divergence between CPV of this study and other reference strains. PCR and the sequence analysis confirmed canine parvovirus-2a as the etiology of the disease. Good management is advised to avoid secondary or severe dehydration and marked gastrointestinal fluid hypovolemia with loss of protein and bacterial sepsis.","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85636220","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 conduct a meta-analysis to evaluate the effect of Endometritis on daily milk yield (DMY) and some reproductive indices (pregnancy rate, days open (DO), service per conception (S/C), and days to the first insemination) in lactating dairy cows. Data corresponding to 4037 cows was extracted from eleven research papers with suf-ficient data for analysis. The odds ratio was calculated for binary data (Endometritis incidence and pregnancy rate) by using the multinomial logistic regression, while the summary estimate was calculated for continuous data (DMY, S/C, and DO) by using the Linear mixed model (Multilevel regression). The odds ratio (OR) of Endometritis had a significant difference among different studies and years, paper No.4 recorded an equal number of diseased and healthy cows (OR=1), so we take this paper as a reference category, OR was the highest (1.6) for paper No.10, while it was the lowest (0.2) for paper No. 2. Concerning the pregnancy rate, Endometritis significantly reduced the pregnancy rate by 45% compared with the healthy cow. Regarding the DMY, Endometritis had a significant reduction in DMY by 1.7 kg rather than the healthy one. Concerning the DO, the cow that suffered from Endometritis had a more prolonged DO by 58 days than the healthy one, also S/C had a significant increase by 1.6 compared with healthy cows.

There has been an unsettling rise in the antimicrobial resistance (AMR) identified in animals, which may transfer to people through direct contact, environmental pollution, and food consumption. Efficient poultry health and welfare management and quick diagnosis of bacterial infections in poultry farms can lessen the demand for antibiotics, which is reflected on the spreading of epidemics and AMR. Internet of thinking and machine learning are branches of Artificial intelligence that enable intelligent autonomous systems with human workers remotely managing operations. Machine learning technology plays a role in tracking and preventing infections in poultry farms, which can reduce the need for antibiotic treatment in poultry and, as a result, limit the transmission of antibiotic-resistant pathogens to humans. This information is further analyzed by powerful processing computers with the aid of massive storage devices to seek for trends and hints to pinpoint the locations of disease outbreaks and cases of resistance. The utilization of this knowledge will make it easier to prevent epidemics in the future, reducing the demand for antibiotics. Therefore, this review offers insight on the current AI practices in the management of poultry farms as well as opportunities and concerns around antibiotic resistance throughout the world.","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88409576","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}
