Abstract

CONS are one of the most frequent causes of nosocomial outbreaks in hospitals and are reservoirs of multiple antimicrobial resistant determinants. Identification and speciation of CONS has become important due to the growing recognition and medical importance to define their clinical significance. S.caprae has the ability to produce a biofilm in vitro which itself serves as a virulent factor for many infections. The study was to screen MRSA in nasal swabs among health care workers. Routinely isolation of genus staphylococci was done based on catalase test. For differentiating coagulase positive and coagulase negative staphylococci were done based on slide coagulase and tube coagulase test. CONS species was identified by Vitek 2 system Most important virulence factor in CONS spcies was biofilm production. So we checked biofilm production in cons species. Out of 82 nasal swabs that were collected from both right and left nostril, organisms were found in 72(87.8%) samples of both right and left nostril. Staphylococcus caprae was found predominantly in 56(77.7%) of 72 samples. 8(11.1%) samples showed the growth of Staphylococcus lugdunensis. Staphylococcus schleiferi and Staphylococcus cohnii were found in four sample each. Out of 56 S.caprae, 12(21.4%) samples showed strong biofilm production, 28(50%) showed moderate and 16(28.5%) showed weak. Our study shows a large number Staphylococcus caprae from the nasal swabs, that has got the significant property of biofilm production which itself serves as a virulent factor for causing infections. So, some of the CONS are considered pathogenic and it should be speciated to avoid deaths caused by infections
