Methicillin-resistant Infection and its Health Perspective: A Review.

BACKGROUND

Methicillin-resistant (MRSA) is a potential threat globally since it is associated with high morbidity and mortality. In addition, the ability of MRSA to develop resistance and adapt to various environments makes it exceptional from other bacterial strains. Effective management is best determined by the site of infection.

OBJECTIVES

This study aims to summarize and assess the epidemiology of MRSA, resistance, detection of MRSA in humans, animals, and food products, treatment employed, and combination therapy.

METHODS

For the present review, we collected data from PubMed, Embase, Web of Science, BioMed Central, Medline, Encyclopedia of Life Sciences, Scopus, Cochrane Library, and ScienceDirect that report the epidemiology of MRSA, drug resistance in MRSA, spread of MRSA infection, diagnosis of infection, existing and emerging remedies of MRSA infections. Collected data were analyzed and represented in this article with the help of Figures and Tables.

RESULTS

resistance to vancomycin is because of genetic adaptation and also due to the widespread and indiscriminate use of antibiotics in the treatment of MRSA infection. Specifically, infections related to vancomycin-resistant S. aureus are life-threatening and difficult to treat. MRSA epidemiology with the recognition of community-acquired-MRSA transmission between livestock and humans is also reported and is alarming. Multiple studies suggested that early detection of MRSA colonization and elimination of carriage can help reduce the risk of subsequent infection. Specifically, PCR-based screening from different body sites offers the highest overall sensitivity for the detection of MRSA carriage.

CONCLUSION

Screening novel mutants and methods of transmission in each environment will assist in managing MRSA. Further, effective MRSA control in all clinical setups is required with the avoidance of uncontrolled antibiotic usage.
