Among multiresistant Gram-positive microorganisms, stands out methicillin-resistant Staphylococcus (MRS), an opportunistic pathogen associated with hospital acquired and community infections reported in medicine and large increase in reports of veterinary medicine. In veterinary medicine, numerous reports regarding several species of animals have been described. MRS is intrinsically resistant to all ?-lactam drugs. In veterinary medicine, numerous reports regarding several species of animals have been described, but Staphylococcus aureus with intermediate resistance and resistant to vancomycin (VISA/VRSA) has not yet been reported in veterinary medicine, still need further study. Staphylococcus spp. are also related to antimicrobial resistance of macrolides, lincosamides, and streptogramin B (MLSB) group, that has the same mechanism of action, although the drugs belong to different classes. In veterinary medicine, clindamycin (lincosamide class) is widely used for skin infections, wounds, bone infections, pneumonia, infections of the oral cavity, and infections caused by anaerobic bacteria, besides being used for treatments of MRS infections. Enterococcus is another resistant Gram-positive microorganism, from which vancomycin-resistant enterococci (VREs) are the most important strains. There are several reports of VREs in veterinary medicine due the use of a similar antimicrobi
