Abstract

To determine the frequency of nasal carriers of strains of methicillin-resistant Staphylococcus aureus (MRSA) and the antimicrobial resistance pattern of these strains, obtained from health workers from four hospitals in Nicaragua. A descriptive cross-sectional study was conducted between 1 June 2009 and 30 September 2010. Nasal swabs were taken from health workers who voluntarily agreed to participate in the study, and were cultured on an oxacillin-resistant screening agar base (ORSAB) medium. The S. aureus isolates were identified using ordinary methods, and methicillin resistance was confirmed based on the presence of the mecA gene using the polymerase chain reaction technique. The antimicrobial resistance pattern was detected by the disk diffusion method. Each participant signed an informed consent form before the samples were taken. A total of 569 health workers participated in the study: 208 from one hospital in León, 155 from two hospitals in Chinandega, and 206 from one hospital in Managua. The frequency of nasal MRSA carriers was 9.6% in León, 11.6% in Chinandega, and 6.7% in Managua. The MRSA resistance profile was similar in the four hospitals, and all the strains were sensitive to vancomycin. Of the total MRSA strai...Continue Reading

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
