This chapter reviews the summarized data on susceptibility patterns and prevalence and epidemiology of resistance for the most clinically relevant staphylococcal and streptococcal pathogens in animals. The chapter focuses mainly on resistance in Staphylococcus aureus, Staphylococcus hyicus, and Staphylococcus intermedius. The first isolation of methicillin resistant Staphylococcus aureus (MRSA) from a veterinary specimen was reported from bovine mastitis in Belgium by Devriese et al. in 1972. The presence of other resistance genes and mechanisms has not been examined in streptococci of animal origin. Antimicrobial agents are most often used to control infections caused by these two groups of bacteria. The continuous monitoring of staphylococci and streptococci from animal infections is an essential prerequisite for early detection of new trends in the development of resistance to antimicrobials commonly used to control these infections. However, standardized procedures need to be made available for unambiguous species identification and for in vitro susceptibility testing, and such procedures also need to be applied by researchers in this field to make the results of susceptibility testing more comparable. More knowledge about the ability of certain subtypes to acquire resistance, together with the development of means to control such clones, could perhaps provide new means of controlling the increase in resistance.
