Staphylococcus aureus is the microorganism that causes the zoonotic disease. It is a Gram-positive, non spore forming, facultative anaerobic microorganisms that can cause haemolysis in blood and plasma coagulation. S. aureus is a salt-tolerant microorganism resistant to freezing, desiccation, chemicals and disinfection (Cimolai, 2008). Staphylococcus aureus is able to genetically modify their cell envelope proteins, microorganisms resistant to antibiotic exposure (Bocher, 2008). Methicillin-resistant S. aureus (MRSA) contain the mecA gene conferring antimicrobial resistance not only to methicillin and beta-lactam antibiotics but also to cephalosporins, tetracyclines, aminoglycosides, macrolides, chloramphenicol, and fluoroquinolones (Lee, 2003; Seguin et al.), as well as in recent years to vancomycin (Tenover, Goering, 2009), which is one of the most effective and commonly used agents for MRSA infections (Boucher, Miller, Razonable, 2010), thus creating a problematic disease treatment (both veterinary medicine and humanitarian medicine) (Otter , French, 2010). Studies have shown that MRSA is fairly common in Belgium (Olivier, 2009), the Netherlands (van Duijkeren et al., 2007.), Etc. Europe. MRSA arriving in the air of piggery; can also infected service personnel. A German study found that 86% of the pig complex service staff is MRSA (ST398 genome) carriers and 45% of veterinarians working in the pig industry (Cuny et al., 2009). No data is available on the situation in Latvia; therefore, to determine the possibility of the spread of MRSA in Latvia, it is necessary to investigate the presence of the agent, genotype, resistance and possible transfer paths in pig complexes.
