Infections Caused By S. aureus MRSA and Natural Antimicrobial Mechanisms to Reduce These Contaminants

Abstract

The advance of S.aureus infections, strain/clone identification methods prevalent in hospitals and resistant to antimicrobials needs to be rapidly effective due to the shortage of new antimicrobial agents. Objective: of this work is to perform a literature review on the epidemiology of methicillin-resistant strains of S.aureus in circulation in Brazil. An integrative literature review was used, which allows summarizing previous research and obtaining general conclusions from them to analyze the scientific knowledge on the subject to be investigated. Methodology:The databases consulted were Latin American and Caribbean Health Sciences Literature (LILACS), International Health Sciences Literature (PubMed), Scientific Electronic Library Online (SCIELO). Literature Review: dissemination in Brazil are: Brazilian epidemic clone (ST239/SCCmecIII) and the Pediatric clone (USA400), are in circulation in hospitals in Brazil, these present a genetic pattern of virulence factors (SCC mec I to IV), PVL proteins, among others, differentiated between them and the Brazilian region with more studies is the Southeast region. Conclusion: Studies are needed to provide greater knowledge about the molecular epidemiology, evolution and antimicrobial resistance of methicillin-resistant S. aureus clones in Brazil, especially in the North and Northeast regions of the country.
