Extended-spectrum-beta-lactamase-producing Enterobacteriaceae strains in various types of private health care centers.

During a 2004 survey, 49 extended-spectrum-beta-lactamase-producing enterobacteria were collected in 20 French private health care centers and one local hospital. They included 12 CTX-M-producing Escherichia coli strains (1.8% versus 0.

Investigation of an outbreak of Ralstonia pickettii in a paediatric hospital by RAPD.

In 1995, over a 5-day period, Ralstonia pickettii was isolated from six separate blood cultures from six paediatric patients in four different units of the Bordeaux paediatric hospital. The patients did not present fever or any other symptom of septicaemia. Epidemiological investigation cast suspicion on distilled water and 0.

[Neonatal staphylococcal epidermolysis due to maternal-fetal transmission].

Introduction: The staphylococcal scalded skin syndrome (SSSS) is due to exfoliative toxins A or B excreted by some strains of Staphylococcus aureus. This syndrome is exceptional in the first hours of life. We report a case of SSSS due to materno-fetal infection.

Detection of point mutations associated with resistance of Helicobacter pylori to clarithromycin by hybridization in liquid phase.

When the standard procedure for determining antibiotic susceptibility of bacteria is used, the results are delayed, especially for bacteria that grow slowly, such as Helicobacter pylori. Treatment for this bacterium may involve clarithromycin, a compound for which resistance has been associated with point mutations on the 23S rRNA gene. This resistance is currently found in organisms isolated from 0 to 15% of patients and jeopardizes the success of the treatment.

Clinical relevance of resistant strains of Helicobacter pylori: a review of current data.

Acquired resistance of Helicobacter pylori to metronidazole and clarithromycin has been reported, with metronidazole resistance being very common. This has an important clinical impact on dual therapies, as well as on the standard triple therapies. However, when antisecretory drug based triple therapies with amoxycillin or clarithromycin and metronidazole are used, the resistance can be overcome in up to 75% of the cases in most of the studies.
