Conclusion: Our findings suggest that CA-MRSA could be responsible for the majority of the infections caused by MRSA within the hospital at which the study took place.
CA-MRSA strains carry SCCmec type IV or V whereas the majority of HAMRSA strains carry SCCmec type I II or III.
Also among MRSA isolates HA-MRSA were having more resistance rate to various antibiotics than CA-MRSA.
