Resistance Genes Underlying the LS Phenotype of Staphylococcal Isolates from France.

There exist numerous genes disseminated by mobile elements that can confer cross-resistance to lincosamides and streptogramin A compounds in staphylococci. This study investigated the nature and means of dissemination of genes responsible for LS resistance among 24 French clinical isolates screened for reduced susceptibility to lincomycin. The (A) gene was found to be the most prevalent determinant of LS resistance, while Tn appeared to be its exclusive gene support.

Diversity of Acinetobacter baumannii in four French military hospitals, as assessed by multiple locus variable number of tandem repeats analysis.

Background: Infections by A. calcoaceticus-A. baumannii (ACB) complex isolates represent a serious threat for wounded and burn patients.

[Disseminated Trichosporon asahii infection].

The present report describes a case of disseminated Trichosporon asahii infection. Trichosporon species has emerged as opportunistic infectious yeast in immunocompromised patients and is resistant to echinocandins. These antifungal drugs are not recommended for trichosporonosis treatment and yeast species identification be attempted for all clinical isolates, particularly with respect to the choice of antifungal therapy for specific Trichosporon species.

[Diagnosis of Mycobacterium genavense infection by INNO-LiPA MYCOBACTERIA Amplification v2].

Introduction: Diagnosis of atypical mycobacterial infections can be facilitated by molecular biology techniques.

Cases: Two severely immunodepressed patients were admitted for deterioration of their general health status. Bacteriological analysis of histopathologic fragments showed the presence of acid- and alcohol-resistant bacilli.

Rapid identification of Mycobacterium genavense with a new commercially available molecular test, INNO-LiPA MYCOBACTERIA v2.

We report a rare mesenteric localized Mycobacterium genavense infection in a severely immunocompromised human immunodeficiency virus-infected patient. An INNO-LiPA MYCOBACTERIA v2 test was performed directly on biopsy samples. This new molecular tool could be used for simultaneous identification of mycobacterium species from human specimens, but other studies are needed to validate our first results.
