Abstract

Mycoplasma bovis is involved in mastitis, pneumonia and polyarthritis of beef and dairy cattle. Infections can affect all ages and respond poorly to antimicrobial therapy. Variation in antimicrobial susceptibility profiles among isolates of M. bovis recovered from various tissues in dairy or beef outbreaks has been suspected but not verified. Increasing resistance of isolates has been recently documented, 1 so it appears that periodic large-scale surveillance would be useful to veterinarians, diagnosticians and researchers, especially to compare isolates from different regions within the US. It would also be beneficial to establish a standardized method for in-vitro susceptibility testing. This report contains antimicrobial susceptibilities for 223 isolates obtained from five US regions and from four tissue sites.
