Clinical and microbiological profile in intra-abdominal infection

Chaithanya J., Ashwini R. K., Rajagopalan S.


Background: Intra-abdominal infections (IAIs) are different from other infections in a surgical patient. One important aspect is the microbiological analyses, especially in the era of broad spread of resistant microorganisms. The study was designed to describe the clinical and microbiological profiles of IAI.

Methods: A prospective study was conducted for a period of 1 year (December 2016 to November 2017) in Rajarajeswari Medical College and Hospital, Bangalore. Patients admitted and operated for acute abdomen/ IAI were included in this study and were analyzed.

Results: In 1 year period a total of 112 patients with IAI were assessed. A total of 5 types of micro-organisms were cultured. All the cultures were polymicrobial with aerobic organisms pre-dominantly gram negative bacilli (E.coli). The most common site was appendix. E. coli in this study showed 100.0% susceptibility to imipenem, 86% to meropenem and 77.6% to amoxi-clavulanate.

Conclusions: The most common site of IAIs was appendix (50%). E. coli (52%) is the most common organism isolated.
