Management of an outbreak of postpartum Streptococcus pyogenes emm75 infections.

Background: Streptococcus pyogenes is a well-known cause of postpartum infections and is causing significant morbidity and mortality.

Aim: To describe measures taken to control an outbreak of postpartum infections caused by S. pyogenes emm75 on a maternity ward.

Colonization of β-hemolytic streptococci in patients with erysipelas-a prospective study.

Erysipelas is a common skin infection causing significant morbidity. At present there are no established procedures for bacteriological sampling. Here we investigate the possibility of using cultures for diagnostic purposes by determining the perianal colonization with beta-hemolytic streptococci (BHS) in patients with erysipelas.

Clinical and microbiological features of bacteremia with Streptococcus equi.

Streptococcus equi (SE) rarely causes human infections. We identified 18 SE isolates from blood cultures. The focus of infection was unknown (n = 5), arthritis (n = 3), catheter-related (n = 2), pneumonia (n = 2), or other (n = 6).

Species and emm-type distribution of group C and G streptococci from different sites of isolation.

beta-Haemolytic streptococci of groups C (GCS) and G (GGS) from human infections typically belong to Streptococcus dysgalactiae and are important human pathogens. Among GGS (183 isolates), several emm-types were identified without significant differences between different sites of isolation. For GCS (79 isolates), the type-distribution was markedly different and more restricted.
