Between-herd prevalence of Mycoplasma bovis in bulk milk in Flanders, Belgium

摘要: Mycoplasma bovis (M. bovis) is a highly infectious pathogen of cattle causing pneumonia, polyarthritis, otitis, and less frequently, subcutaneous abscesses, abortions meningitis. Ineffective drugs treatments, culling infected cows loss milk production can lead to significant economic on dairy farms. The early detection excreting M. bacteria prevent mastitis outbreaks warranted. Reports suggest that the risk higher in larger herds. objective this study estimate herd-level prevalence Flanders, Belgium by culturing bulk tank samples taken from Three per herd were over four weeks, with collection intervals two weeks. Culturing was done after pre-incubation using modified Hayflicks media increase chances recovery bacteria. For identification bovis, tDNA intergenic spacer PCR used. In three herds (1.5%) 200 sampled, isolated one consecutive samples. We conclude Flanders 2009 at least 1.5% had or more milk. frequent monitoring detect presence especially expanding farms often purchase replacement animals, should be encouraged order monitor success control procedures following an outbreak mycoplasmal herd.
