The genome sequence and annotation of Campylobacter coli strain IPSID-1 are reported here. This bacterial isolate is the first to be cultured from a patient with immunoproliferative small intestinal disease (IPSID). The draft genome sequence is 1.683 Mb long, comprises 64 contigs, and has 31.26% G+C content.

Epidemiology and antimicrobial resistance of Streptococcus pneumoniae in France in 2007: data from the pneumococcus surveillance network.

Antimicrobial resistance of Streptococcus pneumoniae in France is closely monitored by the pneumococcus surveillance network, founded in 1995, which collects data from regional observatories (Observatoire Régionaux du Pneumocoque [ORP]). In 2007, 23 ORPs analyzed the antibiotic susceptibility of 5,302 isolates of S. pneumoniae recovered in France from cerebrospinal fluid, blood, middle ear fluid, and pleural fluid, as well as from adult respiratory samples. The study showed that 38.2% of the strains were nonsusceptible to penicillin, 19.3% nonsusceptible to amoxicillin, and 10.5% nonsusceptible to cefotaxime. The percentage of pneumococcus nonsusceptible to penicillin varied according to both the sample and the age of the patient (child/adult): blood (27.8%/32.5%), cerebrospinal fluid (33.7%/34.6%), middle ear fluid (60.2%/27.5%), and pleural fluid (50.0%/31.0%). Between 2003 and 2007, the frequency of penicillin resistance in invasive pneumococcal disease gradually decreased from 46.4% to 29.0% in children and from 43.8% to 32.7% in adults. This decrease coincided with the introduction of a seven-valent pneumococcal conjugate vaccine into immunization programs and with a general reduction in levels of antibiotic consumption in France.

Serotype distribution and antibiotic resistance of Streptococcus pneumoniae strains isolated from adults in France: evolution between 2001 and 2003.

Antibiotic-resistant Streptococcus pneumoniae (Sp) are described around the world. The present national surveillance study report analyzes more than 6000 Sp strains, isolated from adults across France in 2001 and 2003, from blood cultures (3086 in 2001 and 3164 in 2003), cerebrospinal fluid (respectively, 238 and 240), or middle ear fluid (respectively, 110 and 100). The proportion of isolates with reduced susceptibility to penicillin fell significantly between 2001 and 2003 from 46.5% to 43.9%. The proportion of high-level resistant strains to penicillin minimal inhibitory concentrations (MIC > 1 mg/L), amoxicillin, and cefotaxime (MIC > 2 mg/L) slightly decreased but remained low: 10.6%, 1.2%, and 0.2% in 2003. Resistance to other antibiotics (erythromycin, cotrimoxazole, tetracycline, and chloramphenicol) also decreased. Decrease in prevalence of penicillin-resistant Sp varied according to specimen source. The proportion of penicillin nonsusceptible pneumococci decreased in blood cultures and middle ear fluids between 2001 and 2003 but increased in cerebrospinal fluid (43.4% and 46.5%, respectively). Serotypes covered by the heptavalent vaccine accounted for 42.4% of all isolates recovered in 2001 and 46.1% in 2003. Prevalence of antibiotic-resistant Sp decreased in 2003 in France.

Antimicrobial resistance data on 16,756 Streptococcus pneumoniae isolates in 1999: A Pan-Regional Multicenter Surveillance Study in France.

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.

Vertebral osteomyelitis due to Bartonella henselae in adults: a report of 2 cases.

We describe 2 adult patients (1 of whom was infected with human immunodeficiency virus) with osteomyelitis due to Bartonella henselae. Diagnosis was established on the basis of direct identification of the microorganism in one case and seroconversion in the other. Both patients recovered completely within 3 months.

Enterococcus gallinarum endocarditis occurring on native heart valves.

We report the first case of Enterococcus gallinarum endocarditis developing on normal native heart valves. Using phenotypic and molecular methods, a precise identification of this naturally vancomycin-resistant species allowed an optimal antibiotic therapy and the patient's recovery.
