Clonality, virulence and the occurrence of genes encoding antibiotic resistance among Staphylococcus warneri isolates from bloodstream infections

Coagulase-negative Staphylococcuswarneri is an opportunistic pathogen capable of causing several infections, especially in patients with indwelling medical devices. We evaluated the virulence-associated properties of 23 clinical isolates recovered from blood specimens. In addition, the carriage of biofilm-associated genes, as well as antibiotic-resistant genes, was identified. S. warneri isolates appeared to be clonally unrelated and revealed a...
