Abstract: A prospective study was carried out between July 1999 and July 2001, of 50 patients of both sexes, between 16 and 80 years of age, hospitalized in the Surgery ward of the Chiquinquirá Hospital in Maracaibo, and diagnosed with the pathology of non-acute, lithiasic or non-lithiasic bile infection. All were to undergo surgery of the biliar tree, for the purpose of determine the frequency of biliar infection, to establish the specific antibiotic sensibility of the bacteria in bile culture, to reduce the cost of therapeutic expenses, and to identify the most frequent specimens. The ages in which there was greater affectation was in the third and fourth decades of life. The female sex is most affected, with a total of 96% of the patients under study. The number of cultures that were positive was significantly high (35%). Gallbladder bile and choledocol duct cultures in which there was bacterial growth were appropriately the same, 18 (36%), against 17 (34%). The microorganisms that were isolated on most occasions were 9 aerobic bacteria (75%), and of these, the ones that grew with more frequency were the gram negative species (77.8%), and of these, the one that was more frequently positive in the cultures was Escherichia coli in 28.5% of the cases. Bacillus gram negative bacteria were reported as sensitive to antibiotics of the aminoglycosides and quinolons types, and sensitive to betalactamics that were administered in association with the inhibiting compound, betalactamase. The gram positive enterococcus isolate showed sensitivity to penicillin and its natural and synthetic derivates as well as to those associated with betalactamase inhibitors. The anaerobic bacteria that grew was reported sensitive to penicillin and cephalosporins of third and fourth generation, as well as to betalactamics associated with the inhibitors of the enzyme betalactamase. Resumen: Se realizó un estudio prospectivo entre julio de 1999 y julio de 2001, en 50 pacientes de ambos sexos, realizándose en cada uno cultivo de bilis ...
