Association of Gene in MSSA and MRSA Strains among Diabetic Ulcer Patients from Odisha, India.

has emerged as an important pathogen among diabetic foot ulcers in patients with diabetes. Infections with in diabetic ulcers need surveillance of resistant microbial profile to provide the basis for empirical therapy for the reduction of lower extremities amputation. Panton valentine leucocidin () is considered as one of the major virulence gene of which is responsible for destruction of white blood cells and tissue necrosis. This pore forming cytotoxin gene is carried out by both methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains. The present study described the prevalence of gene in MSSA and MRSA strains isolated from diabetic ulcer patients treated during November, 2019 to January, 2021 from a tertiary care hospital, Odisha. Infected tissue and blood samples from these patients were collected aseptically and sub-cultured using different media and standard techniques. The isolated genomic DNA of MSSA and MRSA strains were subjected to PCR assay for the detection of gene. Two hundred ten out of 402 diabetic ulcer patients were isolated having 59.52% MSSA and 40.47% MRSA strains. Wagner's grade III and grade IV ulcers were most prevalent in these ulcer patients. The prevalence of gene in MSSA strains was more in comparison to MRSA strains. Forty five resistance patterns were observed from the antibiogram profiles of The present study highlighted that gene could not be a marker for the detection of MRSA and MSSA strains in diabetic ulcer patients.
