Molecular Analysis of Antimicrobial Resistance among Isolated from Diarrhoeic Calves in Egypt.

The present study was designed to investigate the presence of genes that conferred resistance to antimicrobials among that were isolated from diarrhoeic calves. A total of 120 faecal samples were collected from diarrhoeic calves that were raised in Kafr El-Sheikh governorate, Egypt. The samples were screened for .

Endophyte-Infected Tall Fescue Affects Rumen Microbiota in Grazing Ewes at Gestation and Lactation.

Tall fescue () is a cool-season perennial grass that is widely used as a forage for many livestock species including sheep. An endophyte ( in tall fescue produces ergot alkaloids that enhance plant survival but produce toxicosis in animals. The objective of this study was to investigate the rumen microbiota from gestation and lactation in ewes grazing tall fescue pastures with high (HA) or moderate (MA) levels of endophyte infection, and their relationship with serum parameters.
