Staphylococcus aureus (S. aureus)-associated infections are one of the major threats to public health. The aim of the present study was to determine the antibiotic resistance pattern as well as the genetic characterization of methicillin and vancomycin resistant S. aureus (VRSA) isolated from a tertiary care hospital in Lahore. The S. aureus isolates were isolated from different clinical samples, identified by biochemical testing, and subjected to antibiotic susceptibility testing via the disc diffusion method or broth microdilution method. The methicillin resistance gene (mecA) and vancomycin resistance gene (vanA) were amplified by the polymerase chain reaction. The S. aureus isolates showed high incidences of resistance against methicillin (76%) and moderate incidences of resistance to vancomycin (14%). Isolates were also resistant to several other drugs, such as cefoxitin (76%), ertapenem (83%), ampicillin (81%), tobramycin (78%), moxifloxacin (76%), and tetracycline (74%). An encouraging finding was that 98% of isolates were susceptible to tigecycline, indicating its possible role in the treatment of methicillin-resistant Staphylococcus aureus (MRSA) and VRSA, as well as the multi-drug resistant S. aureus. The mecA gene was detected in 33.3% of tested isolates (10/30), while the vanA gene was also detected in 30% (9/30) of the tested isolates. In conclusion, the frequent presence of methicillin and vancomycin resistance in S. aureus appraises the cautious use of these antibiotics in clinical practices. Furthermore, it is suggested that there should be continuous monitoring of tigecycline treatments in clinical setups in order to delay the development of resistance against it.

 Objective: The aim of this study was to find the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) carrier status in anterior nares and hands of health-care professionals working in orthopedic wards of a tertiary care hospital and to decolonize them to reduce spread of MRSA to their patients.Methods: The study was conducted in a super specialty, tertiary care teaching hospital. The samples were collected from anterior nares, palm, web spaces, and fingertips of 140 health-care professionals (48 doctors, 74 nurses, and 18 technicians) working in orthopedic wards using sterile pre-moistened swabs. MRSA carrier status was identified by Kirby-Bauer disc diffusion method.Result: Most (76.4%) of the health-care professionals were <30 years of age and 51% were male. MRSA in anterior nares of doctors was 4.3%, nurses 1.4%, and technicians 0.7% and none had MRSA in their hands. Methicillin-sensitive Staphylococcus aureus (MSSA) growth was more among nurses (nurses - 5.7%, doctors - 2.1%, and technicians - 1.4%) in anterior nares. In addition, 1.4% nurses’ hands were colonized with MSSA. Both MRSA and MSSA carriers were decolonized effectively and repeat sampling showed no growth.Conclusion: Health-care professionals have a greater chance of transmitting MRSA to patients and orthopedic patients are more susceptible for infection. Although MRSA carrier status was not very high among orthopedic health-care professionals compared to previous studies, it cannot be ignored. Nasal mupirocin and bath with chlorhexidine soap were effective in decolonization. Periodic screening and treatment of colonizers would help in elimination of MRSA carriage.
