Evolution of methicillin-resistant Staphylococcus aureus clones in Latin America

Abstract

A variety of epidemic MRSA clones are circulating in Latin America, some of which harbor genes that encode multidrug resistance or enhanced pathogenicity. Continued collection and reporting of epidemiological data is crucial for effective prevention and treatment.

Diseño de dos metodologías moleculares para la rápida identificación de aislamientos de Staphylococcus aureus resistente a meticilina asociados a la comunidad en Colombia

“…Furthermore, even if these methods were based on Colombian CA-MRSA isolates, they have the potential to identify CA-MRSA isolates in the for the entire Andean region (Colombia, Venezuela, Ecuador and Peru), given that the epidemiology of these countries is similar to that of Colombia. The pulsotypes obtained from PFGE show that the majority of the HA-MRSA isolates have a close genetic relation to the Chilean clone; and the CA-MRSA isolates, as in Colombia, are genetically related to the USA300 clone (10,30). These determinations will be of value even if additional studies are required to confirm the STs and whether the STs possess these same specific virulence factors.…”

Susceptibilidad antimicrobiana y diseminación policlonal de cepas de Staphylococcus aureus

“…Debido a su gran capacidad de diseminación, es necesario implementar programas efectivos de vigilancia para la identificación y control de cepas epidémicas 1,2 . SARM suele ser resistente a todas las penicilinas, carbapenémicos y cefalosporinas.…”

Comparative studies on the antibacterial activities of leaf extracts of Azadirachta indica and Psidium guajava and antibiotics on methicillin and vancomycin resistant Staphylococcus aureus

“…6 Over the last few decades, the number and proportion of vancomycin-resistant S. aureus (VRSA) and methicillin-resistant S. aureus (MRSA) infections in different countries has increased. 7,8 Several studies have shown that MRSA strains are highly resistant to antibiotics. [9][10][11] Despite the discovery of new drugs for the treatment of infections caused by VSRA and MRSA, outbreaks of MRSA/VRSA infections often appear in hospitals, clinics, nursing and elderly homes.…”
