Antimicrobial resistance (AMR): The results of an antibiotic susceptibility testing trial of Staph. aureus isolates showed that 75-80% isolates were multidrug resistant. The isolates were found to be 100% resistant to amoxicillin, ampicillin and penicillin G, 95% resistant to cephalexin, 82% resistant to streptomycin, 75% resistant to oxacillin, 64% resistant to erythromycin, 50% resistant to tobramycin, 46% resistant to tetracycline and 39% resistant to vancomycin. None of the Staph.

Antimicrobial resistance (AMR) is a global threat to human and veterinary medicine. Often it is not known to which antimicrobials specific mastitis-causing pathogens such as Streptococcus uberis are resistant or to which new antimicrobials they are sensitive to. A complicating factor is that one of the resistance strategies of many pathogens which makes it more difficult to treat than their planktonic counterparts, is biofilm formation. A further complicating issue is that virulence factors of Str.
