Osteoarticular and skin and soft-tissue infections caused by Streptococcus agalactiae in elderly patients are frequently associated with bacteremia

Abstract

Older persons (≥65 years) are at risk for invasive group B streptococcal (GBS) infections. The most frequent clinical syndromes in 174 infection episodes were osteoarticular (40%) and skin and soft-tissue infections (30%). In 36% of episodes, a companion microorganism was isolated, and in 45%, blood culture results were positive. Antibiotics were streamlined after species identification in 29% of monomicrobial infections. These findings have clinical and therapeutic implications for GBS infections in the elderly.

Keywords: Group B Streptococcus; Infections in the elderly; Streptococcus agalactiae.
