Abstract
Seven species of mycoplasma plus 1 or more unknown species were found to cause bovine mastitis in California [USA]. The frequency of cases and number of species of mycoplasma in samples received at the laboratory increased from 1976 to 1978. By survey, nearly 4% of samples of bulk tank milk from dairy farms contained mycoplasma of potential pathogenic significance. Acholeplasma laidlawii was frequently isolated from samples from cows and from farm bulk tanks during wet, rainy weather in the spring of 1978, apparently as contaminants only. The prevalence of positive bulk tank milk samples in an area appeared to parallel the prevalence of clinical mycoplasmal mastitis problem herds.
