Incidence of clinical mastitis associated with mycoplasma infection

Incidence of clinical mastitis was calculated in three farms [I, II and III]. It was higher in winter 7.5%, 6%, and 8.5%, respectively, while in the summer season it was 2.7%, 4.1%, and 6.9% in the three farms, respectively. From the clinically mastitic milk samples collected from the three farms 160 [18%] were not respond to bacteriological examination and treatment. These samples were tested for the isolation of mycoplasma species. M. bovis [14.37%] and M. bovigenitalium [13.12%] were isolated from the clinically mastitic milk samples
