BACKGROUND Campylobacter bacteremia is uncommon. The influence of underlying conditions and of the impact of antibiotics on infection outcome are not known. METHODS From January 2000 through December 2004, 183 episodes of Campylobacter bacteremia were identified in 23 hospitals in the Paris, France, area. The medical records were reviewed.

The aim of this study was to evaluate the annual prevalence of multidrug-resistant tuberculosis (MDRTB) and to describe the characteristics of the patients with MDRTB in France. Annual questionnaire surveys from 1992-1999 were mailed to all French microbiological laboratories performing mycobacterial cultures. A total of 264 distinct patients were reported(More)
OBJECTIVE The aim of this study was to evaluate the usefulness of various laboratory results for differential diagnosis of bacterial (BM) and nonbacterial meningitis (NBM) with negative initial Gram stain. DESIGN AND SETTING A prospective multicenter study was conducted in the emergency departments of 3 teaching hospitals. PARTICIPANTS AND METHODS(More)
OBJECTIVES To assess trends in quinolone susceptibility of Enterobacteriaceae isolated in a large university hospital. METHODS Between 1992 and 1998, bacterial isolates were collected each year during a 3-month period to evaluate annual changes in susceptibility. In addition, the activities of fluoroquinolones (pefloxacin, norfloxacin, ofloxacin,(More)
BACKGROUND The Assistance Publique-Hôpitaux de Paris (AP-HP) institution administers 38 teaching hospitals (23 acute care and 15 rehabilitation and long-term care hospitals; total, 23 000 beds) scattered across Paris and surrounding suburbs in France. In the late 1980s, the proportion of methicillin resistance among clinical strains of Staphylococcus aureus(More)
OBJECTIVE To measure the rate of primary and secondary drug resistance of Mycobacterium tuberculosis on an ongoing basis. DESIGN Data on all culture-positive tuberculosis were collected prospectively from 1995 through 1997 from a microbiological laboratory network of 19 university hospitals throughout France, and submitted quarterly to the National(More)
We evaluated the sensitivity and specificity of a new semiautomated direct amplification test (DAT), the LCx-MTB, for the diagnosis of pulmonary tuberculosis (TB) and assessed its positive predictive value by focusing on patients with high clinical and radiologic suspicion of pulmonary TB. Respiratory tract specimens from 32 consecutive patients with high(More)
OBJECTIVE To evaluate the role of Mycobacterium bovis in the epidemiology of human tuberculosis in France. DESIGN A national survey in France in 1995 using a questionnaire mailed to all French microbiological laboratories performing mycobacteria cultures. RESULTS M. bovis was isolated in 38 out of 7075 cases of bacteriologically confirmed tuberculosis(More)
OBJECTIVE To determine the impact of recent changes in the epidemiology of tuberculosis in France and other industrialised countries on the primary trends of tuberculosis case rates in a French university hospital. DESIGN Descriptive study of all 4549 culture-positive tuberculosis cases hospitalised at Pitié-Salpêtrière Hospital between 1972 and 1996. (More)
