Introduction: Surgical Site Infection (SSI) is the leading cause of all Healthcare Associated Infections in
developing countries. SSIs are a frequent cause of morbidity and mortality among inpatients of hospitals.
For proper management of the patients it is very essential to know which pathogen has caused the infection
and also its antibiotic susceptibility.
Objectives: 1. To determine the aerobic bacteriological profile, 2. To know the antibiotic susceptibility
patterns of the bacterial isolates.
Materials and Methods: This retrospective study was carried out on 320 culture positive swabs, tissue &
discharge samples received over a one year period from January 2019 to December 2019 in the department
of Microbiology from Surgery, Orthopaedics & Obstetrics and Gynaecology (OBG) departments. Data
analysis was done on the microbiological profile of the aerobic isolates and its antibiotic susceptibility
pattern.
Results: Among the 320 samples monomicrobial growth was seen in 316 (98.75%) samples whereas
polymicrobial growth was seen in 04 samples (1.25%). Out of the 324 isolates Gram negative bacilli
constituted 239(73.76%) and Gram positive cocci constituted 26.24%. The predominant isolate in the
study was Escherichia coli 101(31.17%) followed by Staphylococcus aureus 68(20.98%).The other
major isolates were Citrobacter spp. 48(14.81%), Klebsiella spp. 41(12.65%), NFGNB 24(7.41%), CONS
17(5.25%) and Pseudomonas aeruginosa 14(4.31%).
Conclusion: This study shows that Escherichia coli and Staphylococcus aureus are the commonest
organisms associated with the surgical site infection. Simple measures like appropriate hand hygiene can
go a long way in bringing down the rate of SSI as well as slowing down the further spread of the resistant
hospital strains.
