Introduction

Surgical site infection is a modern day health care challenge of concern, Acinetobacter species is one of the notorious bug that is strongly linked to hospital acquired infections with known significantly resistant to many commonly available antimicrobial agents.

Objective

To determine antimicrobial characteristics of the common circulating Acinetobacter species associated with surgical site infections.

Methods

A laboratory based analytical study was done on all samples received in Bacteriology Laboratory from surgical site infected wounds by swabs that were received from December 2021 to February 2022 from surgical wards and processed using standard microbiological protocols through conventional culture media, antimicrobial susceptibility testing on available disks and data analyzed on sensitivity, resistance and intermediate as outcomes. Data were analyzed both quantitatively and qualitatively.

RESULTS

Acinetobacter species was the most common organism, accounting for 5/10 (50%), with 60% Acinetobacter isolates being multidrug-resistant. 71% of Acinetobacter Positive cases were inpatient with 50% cases sharing an identical ward . Staphylococcus species was second, accounting for 4/14 (28.57%), and  Proteus Species 3/14  (21.43% ). SSI cases were strongly linked to women who underwent CS-Section in 6/14 cases (42.86 %). In addition, SSI 9/10 (90%) was strongly linked with longer hospital stay> 1 Week. On DST profile, piperacillin Tazobactam had a resistant to 100% to all 5 sample, Meropenem 60%, and Ceftazidime 40%.

DISCUSSION

The use of clinical laboratory standards institute guidelines 2020 has a bearing on the antimicrobial choice by laboratories and they are a limiting factor on the variety of use.

CONCLUSION

There exists remarkable multidrug resistant Acinetobacter species associated with surgical site infection in the hospital facility. Thus infection prevention measures need to be put in place to protect patients.
