Materials and Methods: Nasal swab samples were taken from each footballers and a healthy control group for the isolation of staphylococcal strains. The polymerase chain reaction technique was used to determine Panton-Valentine Leukocidin, mecA and icaA/icaD genes in staphylococcal isolates. Results: Among 91 S. aureus strains, the presence of mecA gene was detected as 9.9%. This ratio was 17.9% (27 of 151) among the coagulase-negative staphylococci. A significant difference was found between coagulase-negative staphylococci and S. aureus isolates regarding the presence of mecA gene (P < 0.001). As for the genes of the slime, icaA/icaD genes were detected in 198 of 242 (81.8%) strains. The occurrence of slime genes was 91.2% and 89.4% among the S. aureus coagulase and negative staphylococci, respectively (P > 0.05). There was a statistically significant difference between the frequency of the mecA and slime genes when compared with the healthy control group and the football players (P < 0.01). Of 91 isolates, 22 were found to be methicillin resistant by the oxacillin disc diffusion method, whereas the remaining (220) were methicillin susceptible. Methicillin resistance was detected as 14.9% by the polymerase chain reaction method, whereas it was found as 9.1% by phenotypic methods. Conclusions: Early and accurate diagnosis of virulent staphylococcal strains is crucial because the virulent coagulase-negative and coagulase-positive staphylococcal strains in the nasal floras of footballers may be major potential sources of superficial and deep tissue infections.eninfo:eu-repo/semantics/closedAccessFootballerPaton-Valentine leukocidinmecASlimeStaphylococciVirulence Factors in Staphylococci Isolated From Nasal Cavities of FootballersArticle351327928510.1016/j.amjms.2015.12.016269922572-s2.0-84963546061Q1WOS:000382664600010Q2
