Draft genome sequence of a multidrug-resistant Aeromonas hydrophila ST508 strain carrying rmtD and bla isolated from a bloodstream infection.

Here we report the draft genome sequence of a multidrug-resistant (MDR) Aeromonas hydrophila strain belonging to sequence type 508 (ST508) isolated from a human bloodstream infection. Assembly and annotation of this draft genome resulted in 5028498bp and revealed the presence of 16S rRNA methylase rmtD and bla genes encoding high-level resistance to aminoglycosides and cephalosporins, respectively, as well as multiple virulence genes. This draft genome can provide significant information for understanding mechanisms on the establishment and treatment of infections caused by this pathogen.

Staphylococcus hominis subsp. novobiosepticus strains causing nosocomial bloodstream infection in Brazil.

Objectives: To report the isolation of six Staphylococcus hominis subsp. novobiosepticus (SHN) strains from hospitalized patients with bloodstream infections in two Brazilian hospitals and to characterize their susceptibility profile to several antimicrobials.

Methods: Species identification was performed by biochemical methods and sodA gene sequencing.

Phenotypic and genotypic characterization of VanA Enterococcus isolated during the first nosocomial outbreak in Brazil.

We report the phenotypic and genotypic characterization of 50 VanA Enterococcus clinical isolates from infected patients and 97 isolates from colonized patients obtained during a nosocomial outbreak in a single hospital in São Paulo, Brazil during 1998. The identification of strains to the species level by conventional biochemical and phenotypic tests and by multiplex PCR assay had 100% agreement. Both E.
