Bacteriological study of enterococcus bacteria isolated from different diseases in the female cows

Abstract

The study involved the isolation of enterococcus bacteria and diagnosis of different types of diseases, where (190) samples of cows suffering from different diseases were obtain (34) (18.1%) isolation of Enterococcus were divided into 21 (15.6% ) Of the blood, 8 (52.4%) and 3 (17.6%) of the vagina, but not isolated from the spinal cord samples. The study was conducted on 2 isolates from the blood samples to become the number of isolates (36 isolates). And the study showed that type E. Faecalis was the most common species, with 75% followed by E. faecium (20.2%) and E.galinarium (4.8%), which also revealed the virulence factors of these bacteria, which play an important role in their disease. Bacteria have the ability to produce Haemolysin, Protease, Lipase, β-Lactamase, and the formation of capsules and their ability of Haemagglutination and of the effect of mannos on this process.
