- W4206266980 abstract "Abstract Individuals with Methicillin-Resistant Staphylococcus aureus (MRSA) colonized nasal cavities were at greater risk of developing the infection and can serve as potential reservoirs of transmission. Aim of this study is to determine the extent of nasal carriage and associated factors linked to MRSA in medical and health science students of Arba Minch University (AMU), Ethiopia. An institution based cross-sectional study was conducted at AMU from 01 st August through 30 th November, 2020. A systematic sampling technique was used to recruit the participants. Socio-demographic data were collected using a structured questionnaire. Nasal swabs were collected and S. aureus were identified following standard microbiological methods. Methicillin resistance was tested using cefoxitin disk and antimicrobial susceptibility tests were performed by Kirby-Bauer disk diffusion. Biofilm forming ability was phenotypically detected by micro-titer plate assay. Descriptive statistics and multivariable logistic regression analysis were done by Statistical Package for Social Service (SPSS) version 25. Overall prevalence of Staphylococcus aureus and MRSA were 27.1% (70/258) and 7.4% (19/258) respectively. Methicillin-Resistant S. aureus carriage was higher among medical interns, 16.9% (11/65); isolates were co-resistant to antibiotics, such as trimethoprim-sulfamethoxazole (63.2%) and tetracycline (48.4%). Multidrug resistance (MDR) was observed among 52.6% (10/19) of the isolates. Besides, 31.4% (6/19) of MRSA were biofilm producers and all of them were MDR. Multivariable analysis showed that students having >2 years of mean exposure to hospital [p= 0.048, AOR: 4.99, 95% CI: 1.01-24.66] and those who share clothing and sports equipment [p=0.017, AOR: 5.43, 95% CI: 1.35-21.83] were statistically significant. The overall prevalence of nasal MRSA among students were comparatively lower than that observed in other studies done in Ethiopia itself. An alarming factor is that, 60% of MDR-MRSA were biofilm producers." @default.
