To provide information on the prevention and control of goat abortion bacteria for Guizhou province, this article studied
the composition, distribution and pathogenicity of major pathogenic bacteria of goat abortion in Guizhou province. The bacteria samples
were collected and separated from fetus, uterus, ewe vaginal cotton swab of 91 abortion goats from 10 scale sheep farms in 6 prefectural (state, city) of Guizhou province, identification of bacterium by the gram staining and biochemical tests were conducted, then the pathogenicity test in mice was conducted with the four major advantage bacteria. 13 species bacteria, 159 strains in total, were isolated from the reproductive system of goat in Guizhou province, the bacterial species isolated from abortion goats were significantly more than the healthy goats. The 4 major bacterium existed certain pathogenic to mice, the order of the fatality rates in mice were Pasteurella haemolytica, Streptococcus pyogenes, Staphylococcus saprophyticus and Escherichia coli, the values were 83.3%, 50%, 8.3% and 8.3%,respectively. |
