Abstract
The aim of the study was to investigate probable carrier rate of the healthcare workers and screened for carriers of MRSA as they could pose a potential risk factor for nosocomial transmission when the same carrier are exposed to the hospital setting during their clinical postings. A total of 100 nasal swabs were collected from the nursing staff and doctors. Sterile cotton swabs moistened with glucose broth were used for sample collection. Swabs were cultured on to nutrient agar, blood agar, and mannitol salt agar, incubated at 35 °C for 48 hrs. Staphylococcus aureus was identified by standard methods according to CLSI guidelines. Methicillin resistance was detected by using cefoxitin disc 30pgm on Mueller Hinton agar with 4% NaCL Of the 100 samples screened 30(30%) strains of Staphylococcus aureus were isolated, out of which 16 (53.33%) were Methicillin resistant Staphylococcus aureus (MRSA) and 14 (46.66%) were methicillin sensitive Staphylococcus aureus (MSSA). The overall carriage rate of methicillin resistant Staphylococcus aureus in our study was 16% with the highest rate being seen among the nursing staff (19.35%) and clinical staff carriage rate was lesser (10.52%) as compared to the nursing staff. Chest department samples showed higher carriage rate (33.33%) followed by pediatrics department (28.57%). The present study revealed that HCWs who have contact with patients are at risk of acquisition and colonization with antimicrobial resistant bacteria especially MRSA. Transient hand colonization is the primary mean of cross transmission. Simply education of HCWs on hygienic measures especially proper hand wash is the key to overcome MRSA infection in ICUs.
