[Results of intraoperative bacteriological studies of bile from patients operated on for cholelithiasis]

Complete bacteriological examination of bile was carried out in 123 patients operated on for cholecystolithiasis. The most frequently found Gram-negative bacteria were E. coli and Klebsiella species. The Gram-positive organisms were most frequently Staphylococcus epidermidis, Str. viridans and Str. faecalis. Anaerobes were rarely found. The effectiveness of the antibiotics used was studied.
