Staphylococcus aureus and Methicillin Resistant Staphylococcus aureus (MRSA) Carriage and Infections

Abstract

Staphylococcus aureus is among the most common opportunistic infections worldwide, as it is found as part of the flora in many parts of the body. S. aureus is the leading cause of nosocomial infections with its ability to rapidly colonize the infected area, high virulence, rapid adaptation to environmental conditions, and the ability to develop very fast and effective resistance even to new generation antibiotics. Methicillin-resistant Staphylococcus aureus (MRSA), first identified in the 1960s, is one of the most successful modern pathogens, becoming an important factor in hospitals in the 1980s. MRSA is an important factor, especially in hospitalized patients and healthcare-associated infections. Patients colonized with S. aureus and MRSA are at risk for community-acquired infections. It is critical that multidrug resistance reduces treatment options in MRSA infections and MRSA strains. These microorganisms have been the subject of research for years as they spread and become resistant in both social and medical settings and cause great morbidity and mortality. With the rapid spread of resistance among bacteria, antibiotic resistance has increased the cost of health care, and this has become the factor limiting the production of new antibiotics.

Role of Escherichia coli, Staphylococcus, Salmonella and Brucella Species in Spread of Antimicrobial Resistance Across Species

“…Methicillin-resistant Staphylococcus aureus (MRSA) is a common nosocomial and community-associated pathogen that can colonize or cause infections in both human and animals. S. aureus is a Gram-positive bacterium and causative agent of wide range of infectious diseases such as skin infections, bacteremia, endocarditis, pneumonia, and food poisoning (Yildiz 2022). The organism was originally a leading nosocomial pathogen and afterwards epidemiologically distinct clones emerged in community settings.…”
