[Study of Mycoplasma from the genital apparatus of cattle]. / Prouchvane na mikoplazmi ot poloviia aparat na goveda

ABSTRACT

The study on vaginal mucous secretion in cows with metritis and vaginitis, on fetuses and placentae of cows that had miscarried as well as on preputial secretion of bulls revealed the presence of Mycoplasma organisms associated with V. fetus and other bacterial species. By their reaction to cholesterol, digitonin, sodium polyanetol sulfonate as well as their serum and temperature requirements, the formation of films and spots, their phosphatase activity and biochemical and serologic behaviour the mycoplasmas isolated from the genital tract of cows were specified as A. laidlawii and A. axanthum. From both cows and bulls T-forms of mycoplasmas were isolated. The strains determined as A. laidlawi showed deviations from the species characteristics by the fermentation of glucose, hydrolysis of esculine, and reduction of 2,3,5-triphenyl-tetrazolium chloride.
