Bile Bacteria of Patients with Cholelithiasis and Theirs Antibiogram
To prevent post cholecystectomy infection, the most common microorganisms causing it and their antibacterial susceptibility pattern should be determined. Therefore, the aim of the present study was to determine the exact incidence and nature of the microbial flora in the bile of the patients with cholelithiasis and chronic cholecystitis as well as their antibiotic sensitivity pattern. In this study, a total of 132 samples from the patients were tested for bacterial strains using the appropriate methods for testing them. The isolated bacteria were subsequently subjected to antibacterial susceptibility test using Kirby-Bauer method. The data were analyzed using Frequency, Chi-square and t-test. Fifty of 132 (37.87%) studied patients were positive for bacteria. The most common isolated organisms were Escherichia coli (13; 26%), Enterobacteriaceae (9; 18%), and Salmonella typhi (7; 14%). The most effective antibiotics were sequentially Amikacin, Ceftriaxone, and Clindamycin. Isolating bacteria and determining their sensitivity to different antibiotics may be help physicians take prophylactic measures against postoperative infection of cholelithiasis and chronic cholecystitis.
