Characterization of five types of staphylococcal cassette chromosomal mec genes in methicillin-resistant staphylococcus aureus (MRSA)‎ isolates from Iraqi patients

الملخص EN

The distribution of Staphylococcal Cassette Chromosomal mec (SCCmec) types I, II, III, IV and V was assessed in 137 methicillin-resistant S.aureus (MRSA) isolates obtained from patients from different hospitals in Baghdad city.

Each types responsible for certain virulence factors.

It was found that 38 (27.73%) isolates of MRSA out of 137 contained SCCmecI, the lest percentage of SCCmec types in all MRSA isolates was type II, It was found that 8 (5.83%) isolates only were positive in this type.

While 22 isolates (16.05%) contain SCCmec III.

The number of isolates detected in SCCmec type IV were 53 (38.68%) isolates out of 137 while 86 (62.77%) for type V which represented the highest percentage with contrast with other types.
