Inducible clindamycin-resistant and biofilm formation in the Staphylococcus aureus isolated from healthcare worker’s anterior nasal carriage
Abstract
<jats:title>Abstract</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>The purpose of this study is a new update on the resistance profile, Macrolide–Lincosamide–Streptogramin B resistance mechanisms and biofilm formation in the <jats:italic>Staphylococcus aureus</jats:italic> isolated from health care workers (HCWs) nasal carriage at a children’s teaching hospital in Babol (Northern Iran).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>A total of 143 non-repetitive nasal swab samples were collected from volunteers, where 53.8% (n; 77/143) were HCWs, 33.6% (n; 48/143) medical students, and 12.6% (n; 18/143) resident students. The prevalence of nasal carriers of <jats:italic>S. aureus</jats:italic> was 22.4% (n; 32/143), among them, 40.6% (n; 13/32) were identified as methicillin-resistant <jats:italic>Staphylococcus aureus</jats:italic> (MRSA( carriers. Antimicrobial susceptibility testing showed that erythromycin (68.8%, n; 22/32) and ciprofloxacin (15.6%, n; 5/32) had the highest and lowest resistance rate, respectively. The frequency of resistance genes in the strains was as follows; <jats:italic>ermC</jats:italic> (n; 17/32, 53.1%), <jats:italic>ermA</jats:italic> (n; 11/32, 34.4%), <jats:italic>ermB</jats:italic> (n; 6/32, 18.7%), <jats:italic>ereA</jats:italic> (n; 3/32, 9.4%). Moreover, 50.0% (n; 16/32), 28.1% (n; 9/32) and 21.8% (n; 7/32) of isolates were strongly, weakly and moderately biofilm producer, respectively. Macrolides-lincosamides-streptogramins B (MLSB) antibiotic resistance among <jats:italic>S. aureus</jats:italic> isolates from HCWs nasal carriage have found significant prevalence rates throughout the globe. It is crucial to remember that the development of biofilms and MLS B antibiotic resistance are both dynamic processes.</jats:p></jats:sec>
