We describe the epidemiology ofStaphylococcus aureuscolonization among 200 healthcare workers. The prevalence ofS. aureuswas 28%, and the prevalence of methicillin-resistantS. aureus(MRSA) was 2%. The incidence of MRSA colonization was extremely low. This study suggests that the risk of MRSA transmission to healthcare workers is low in a hospital where MRSA is endemic.

Background: In recent times, emerging resistance to majority of antibiotic classes seen in Methicillin-resistant Staphylococcus aureus (MRSA) isolates is of concern in hospital-acquired infection. MRSA carriage by healthcare workers (HCWs) has been documented to be as high as 50% in some studies. Higher carrier rate increases the risk of developing active infection as well as transmission of infection to the patients. The study aims to establish a relationship between MRSA carrier rate and healthcare workers of a tertiary care hospital in Pune and understand the need for screening regimens, based on the outcome.Methods: A cross-sectional study including health care workers from a tertiary care hospital working in different clinical departments was carried out. Data was collected by taking samples of nasal swabs of 115 HCWs and inoculated immediately on blood agar. Culture plates were incubated at 37°C for 24 hours and colonies were tested by routine diagnostic techniques. Antibiotic sensitivity was tested using cefoxitin discs on Mueller Hinton medium.Results: Prevalence of Staphylococcus aureus carriage was reported in 19 out of 115 (16.52%) healthcare workers, of which 63.2% were MRSA and 36.8% were MSSA. Prevalence of MRSA among Orthopaedic surgeons and General surgeons showed a carrier rate of 25% and 18.2% respectively. Nurses had a prevalence rate of 0.39 %. Overall prevalence of MRSA carriage in healthcare workers was reported to be 10.4%Conclusions: MRSA carriage among HCWs at the hospital is considerably high. The high prevalence of MRSA carriage emphasizes the need for stringent hospital infection control and regular screening regimen of HCWs.

Abstract Background Blood stream infections (BSIs) due to Gram-positive pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) are associated with high mortality ranging from 10 to 60%. The current anti-MRSA agents have limitations with regards to safety and tolerability profile which limits their prolonged usage. Levonadifloxacin and its oral prodrug alalevonadifloxacin, a novel benzoquinolizine antibiotic, have recently been approved for acute bacterial skin and skin structure infections including diabetic foot infections and concurrent bacteremia in India. Methods The present study assessed the potency of levonadifloxacin, a novel benzoquinolizine antibiotic, against Gram-positive blood stream clinical isolates (n = 31) collected from January to June 2019 at a tertiary care hospital in Mumbai, India. The susceptibility of isolates to antibacterial agents was defined following the Clinical and Laboratory Standard Institute interpretive criteria (M100 E29). Results High prevalence of MRSA (62.5%), quinolone-resistant Staphylococcus aureus (QRSA) (87.5%), and methicillin-resistant coagulase-negative staphylococci (MR-CoNS) (82.35%) were observed among bacteremic isolates. Levonadifloxacin demonstrated potent activity against MRSA, QRSA, and MR-CoNS strains with significantly lower minimum inhibitory concentration MIC50/90 values of 0.5/1 mg/L as compared with levofloxacin (8/32 mg/L) and moxifloxacin (2/8 mg/L). Conclusion Potent bactericidal activity coupled with low MICs support usage of levonadifloxacin for the management of BSIs caused by multidrug resistant Gram-positive bacteria.
