Staphylococcus aureus was isolated from the
air samples obtained from surgery, trauma, orthopedics
and gynaecology OTs. Surgical OT showed 50%
prevalence of Staphylococcus aureus in the air which is
highest among all the OTs (Table 2). Coagulase
negative Staphylococci (CoNS) were isolated from the
air samples from all the OTs with the lowest prevalence
in Neurosurgery (16.66%) and CTVS (25%). Lowest
isolation rate for Micrococcus spp was found to be from
CTVS (Cardio thoracic and vascular surgery) OT.
Bacillus spp. was present in the air of the various OTs
with lowest prevalence being 33.3% in the
Neurosurgery, urology and new OT. Air samples
obtained from Surgery and Gynecology & Obstetrics
showed 100% positivity for Bacillus spp.
All the Staphylococcus aureus isolates were
susceptible to most of the drugs except ampicillin and
ciprofloxacin (Table-3). CoNS isolates were found to be
more resistant to various drugs in comparison to
Staphylococcus aureus isolates. Amongst CoNS
isolates, 50% were sensitive to ciprofloxacin, 55% to
