Especies y concentración bacterianas en bilis de colecistectomías realizadas en la Clínica "Cobija", segundo semestre 2009

Abstract

The aim of this study is to determine the most prevalent bacterial species in samples from patients cholecystectomized bile clinic Blanket fort he second half of 2009 management, differentiating between those that occur in the acute and chronic table, also identify the type cholecystitis more frequently and whether a relationship exists between them and the bacterial concentration of those samples were positive, also showed their relationship to the risk factors age and sex. This study is a descriptive research, analytical and longitudinal. Sample 52 patients undergoing cholecystectomy at the clinic shelter in the last six months of 2009, of which the bile was collected during surgery and proceeded to its cultivation on blood agar, thioglycollate broth, 24 hours after the growth was checked colony and proceeds to count and microscopic observation, once identified Gram negative, the Mc Conkey agar and then in kit�s biochemical determination of Enterobacteriaceae. The entire procedure was performed in the laboratory of Bacteriology, Faculty of Medicine Melean Aurelio. The results obtained indicate that the most common bacteria in acute cases are Gram positive and chronic conditions, the streptococci. Sex is more susceptible to female aged between30-34 and 50-54 years. Finally, we observed a direct relationship between bacterial concentrations greater than10000/ml with acute cholecystitis. We conclude that there is a relationship between the type of clinical picture of cholecystitis and bacterial concentration. In addition to the acute condition may be triggered more often by Gram-positive bacilli and Streptococcus related to chronic.
