Antibiotics susceptibility test patterns of bacterial species isolated from the human gallbladder bile of Sudanese patients

الملخص EN

-Objectives This study was carried out to determine the antibiotics susceptibility test patterns of bacterial species isolated from the human gallbladder bile.

These species were belonging to six different bacterial genera four are Gram- negative and two are Gram - positive.

Methods A total of 100 bile specimens from 100 patients (88 females and 12 males), were examined in this study.

The mean age of the patients was (46.

22) years, with a range value from 23-86 years.

The antibiotics susceptibility tests were done to all bacterial isolates using Kirby - Baur disc diffusion method.

Results Most bacterial isolates were found sensitive to many antibiotics.

The results of sensitivity tests showed that there is resistance observed in some species including Pseudomonas spp., Salmonella spp., and Citrobacter freundii.

Enterobacteria are the commonest bacteria examined in our study.

Interestingly, all resistant strains isolated belonged mostly to bacterial species known to cause nosocomial infections
