A woman aged 60 years was hospitalized for Vibrio cholerae serogroup O1 cholera. Twenty-six fellow travelers and 48 health care workers who cared for the patient were individually traced and contacted. Of the 23/27 travelers with diarrhea during the trip, 4 presented antibodies. There was no person-to-person transmission.
The rising prevalence of antibiotic-resistant Streptococcus pneumoniae is a phenomenon observed to different degrees around the world. The present national surveillance study report analyzes a total of 16,756 strains of S. pneumoniae collected across France in 1999. The overall prevalence of S. pneumoniae with decreased susceptibility to penicillin was 44%, to amoxicillin 26%, and to cefotaxime 17%. The proportion of high-level resistant strains to penicillin (MIC > 1 mg/L), amoxicillin and cefotaxime (MIC > 2 mg/L) remained low: 12.3%, 1.8%, and 0.4% respectively. Prevalence of resistance to other antibiotics was high: 53% to erythromycin, 41.7% to cotrimoxazole, 31.8% to tetracycline, and 24.6% to chloramphenicol. Prevalence of penicillin-resistant S. pneumoniae varied according to subject age and specimen source. It was higher in children (52.7%) than in adults (39.8%) and higher in strains isolated from middle ear fluid (63.6%) than from blood cultures (41.8%) in children. S. pneumoniae resistant to other antibiotics were more common in children than in adults, although figures showed geographical variations. Comparison with a previous study realized in 1997 in the same regions confirms a rising trend in the prevalence of resistant bacteria. Therefore, we conclude that prevalence of antibiotic-resistant S. pneumoniae in 1999 continued to rise in France, although strains with high-level resistance to penicillin remained stable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
