BACKGROUND:Few studies have assessed microflora and their antibiotic sensitivity in normal bile and lithogenic bile with different types of gallstones. METHODS:We performed a case control study of 70 bile samples(35 cholesterol and 35 pigment stones from 51 females and 19 males,aged 21-72 years with a median age of 37 years)from patients who underwent laparoscopic cholecystectomy for uncomplicated cholelithiasis,and 20 controls(14 females and 6 males,aged 33-70 years with a median age of 38 years)who underwent laparotomy and had no gallbladder stone shown by ultrasound *** bile samples were aerobically cultured to assess microflora and their antibiotic *** procedures were undertaken under sterile conditions. RESULTS:Thirty-eight(54%)of the 70 patients with gallstones had bacterial *** isolates(26%)were from cholesterol stone-containing bile and 29 isolates (82%)from pigment stone-containing bile(P=0.01,t test). Twenty-eight of these 38(74%)bile samples were shown positive only after enrichment in brain heart infusion medium(BHI)(P=0.02,t test).The overall bacterial isolates from bile samples revealed *** predominantly,followed by ***,Enterococcus spp.,Klebsiella *** S. *** were no bacterial isolates in the bile of controls after either direct inoculation or enrichment in ***:Bacterial isolates were found in pigment stone-containing ***-lithogenic bile revealed no bacteria,showing an association between gallstone formation and the presence of bacteria in *** sensitivity patterns of isolated organisms were similar irrespective of the type of stone.
