An array of multiplex PCR assays for detection of staphylococcal chromosomal cassette mec (SCCmec) types among staphylococcal isolates.

Abstract:

:Staphylococcal Cassette Chromosome mec (SCCmec) element plays a key role in development of resistance by carrying different resistance factors. Therefore, routine and rapid diagnostic approach is considered advantageous for the easy detection of SCCmec elements. So, here we have described the use of three sets of multiplex PCR assay, which can be used to identify SCCmec type I to type XII, unlike other known protocols. MRSA isolates of both hospital and community settings had been utilized to confirm the sensitivity of the method. All the isolates were examined for SCCmec types using multiplex PCR assay followed by sequencing of amplified products. The results confirmed the detection of SCCmec type I, type II, type III, type IV, type V, type VI, type VII, type VIII and type XII, where SCCmec type II having ST1551 and type V with ST2416 were found to be associated with multidrug resistance and were highly prevalent in the study area. This method will be useful for epidemiological assessment as it will be easier to track the resistance among staphylococci for control of infections and its management.
