Infections bacteriennes communautaires aux urgences

ABSTRACT

The most frequent community infections caused by bacteria that are found at medical emergencies are urinary infections and meningiti. This study's aim is to determine the type and frequency of the bacteria isolated at the emergencies, and to test their sensitivity against different antibiotics. Material and methods: We have studied in a prospective way 220 bacteriological samples of 200 patients at the medical emergencies during 7 months from the begining of June 2001 till Janury 2002. Each patient was tested according to the signs he presented and to the available technical means. We did 100 spinal punctures [US], 82 cytological bacteriological urinary examination [ECBU], 21 blood-culture, 8 pus, 6 effusion liquids, 3 plate culture of faeces. Klebsillea and Echerichia coli are responsible for most of the urinary infections. The bacteria found showed a very high level of resistance [almost 100%] against ampicillin and [60%] against amoxicillin / calvolanic acid. However they were sensitive to fluoroquinolons and to 3 rd generation cephalosporins. Pneumococus is the most frequent germ for purulent meningitis. Isolated bacteria were all sensitive to penicillin G. The progression of resistance to antibiotics of the principal community bacteria implies to rationalize the use of antibiotics, and to monitor regularly the resistance of these bacteria, and also to make new therapeutical recommendations based on the local epidemiological data
