The isolation result of mastitis pathogens from TH dairy cow farms
Abstract
Study on the incidence of clinical mastitis (CM) and the presence of the involved pathogens for developing the dairy cow mastitis prevention and control programs as well as treatment protocols is very essential. A
study on dairy cow mastitis and its pathogens at the TH dairy cow farms was conducted. The content of this study included field investigation and data analysis, sampling and testing the specimens according to the
TH laboratory procedures. The studied results showed that the pathogens from the environment accounted for 51.57% of the causative agents (mainly E. coli, Klebsiella, Streptococcus spp., Enterococcus,…). The
opportunity pathogens accounted for 4.6%, mainly CNS (Coagulase negative Staphylococci). The new group of infectious agent was determined to be Mycoplasma bovis and Staphylococcus aureus at low level,
accounted for 0.19% of the isolated bacteria strains. The intensity of the main causative agents from the environment and opportunity pathogens was at 4+ (maximum level). It is indicated that the level of microbial
contamination in the floor of the dairy cow house was relatively high.
