Uses of Diagnostic Ultrasonography in the Diagnosis of Some Digestive Disorders in Cattle and Buffalo

The bovine sector represents an important part of the animal resources in Egypt, as it plays important role in supplying humans with a considerable part of their daily needs of animal-derived proteins via their milk and meat. However, such animal species can be exposed during their life to a wide range of digestive disorders, which affect animal performance and productivity. Ultrasonography plays an essential role in the accurate and rapid diagnosis of several diseases affecting cattle and buffaloes. In this review, we will highlight the role of ultrasonography in the diagnosis of digestive disorders in cattle and buffaloes. &nbsp

Prevalence and phylogenetic characterization of Listeria monocytogenes isolated from processed meat marketed in Egypt

Because of its high case fatality rate, listeriosis locates among the most frequent causes of death due to food-borne illness. In this study, a total of 150 processed meat samples were collected from Giza Governorate, Egypt. Phenotypic and genotypic identification of Listeria monocytogenes was performed using PCR incorporating listeriolysin O virulence gene hlyA followed by DNA sequence analysis. L. monocytogenes was confirmed in 4% of each of beef burger, minced meat, and luncheon samples. Phylogenetic analysis showed that all the six Egyptian isolates have high homology with Colombian isolate (EF030606), except one Egyptian isolate which showed high homology with Indian isolate (EU840690). The public health significance of these pathogens as well as recommended sanitary measures were discussed
