Molecular and phenotypic characterization of methicillin-resistant staphylococcus aureus isolates from a tertiary hospital in the Philippines
Background: Methicillin-resistant Staphylococcus aureus (MRSA) poses a major threat to public health worldwide. There are relatively few studies addressing the molecular epidemiology of MRSA in the Philippines. Methods: This study characterized MRSA isolates in terms of their antimicrobial susceptib...

oai:animorepository.dlsu.edu.ph:faculty_research-51172021-11-26T08:11:23Z Molecular and phenotypic characterization of methicillin-resistant staphylococcus aureus isolates from a tertiary hospital in the Philippines Valle, Demetrio L. Paclibare, Phyllis Anne P. Cabrera, Esperanza C. Rivera, Windell L. Background: Methicillin-resistant Staphylococcus aureus (MRSA) poses a major threat to public health worldwide. There are relatively few studies addressing the molecular epidemiology of MRSA in the Philippines. Methods: This study characterized MRSA isolates in terms of their antimicrobial susceptibility profile, the SCCmec type, and the presence of lukF-lukS genes for Panton-Valentine leukocidin (PVL) and determined the relatedness of the isolates by random amplified polymorphic DNA (RAPD)-polymerase chain reaction (PCR). Results: A total of 236 S. aureus were isolated from clinical specimens of the Makati Medical Center in Makati City, Philippines, between January 2013 and June 2013, and 108 or 45.76 % were found to be MRSA. Results showed that the MRSA strains were resistant to trimethoprim-sulfamethoxazole (20.37 %), azithromycin (10.19 %), gentamicin (5.56 %), and linezolid (4.63 %), while all were susceptible to vancomycin, nitrofurantoin, levofloxacin, minocycline, rifampin, and tetracycline. One isolate was found positive for inducible clindamycin resistance. All of the 108 MRSA strains were confirmed to carry the mecA and SCCmec genes, while the PVL genes were detected in 41 (38 %) of the isolates. Ninety-six isolates (89 %) carried SCCmec type IV, while the remaining isolates carried SCCmec type I (11 isolates) or type III (one isolate). Conclusion: This study is the first to present a comprehensive MRSA surveillance data with molecular characterization in a tertiary hospital in the Philippines. © 2016 Valle et al. 2016-03-14T07:00:00Z text https://animorepository.dlsu.edu.ph/faculty_research/4208 info:doi/10.1186/s41182-016-0003-z Faculty Research Work Animo Repository Staphylococcus aureus Staphylococcus aureus infections--Philippines Methicillin resistance Biology |
