Summary
We present a 2-year survey of bacteraemic episodes due to β-haemolytic streptococci and a case of recurring infection due to group C streptococcus,Streptococcus “equisimilis”. We found 53 episodes of bacteraemia with β-haemolytic streptococci. Group A was the most common, followed by groups B, G and C. The proportion of nosocomial cases was the same in all four groups i. e. 24% (neonatal cases excluded). The clinical picture presented by groups C and G streptococcal cases was indistinguishable from that caused by group A streptococci, but patients with group G bacteraemia were older than patients with group A bacteraemia. Obvious clinical foci were more common in group A than group G cases. Disregarding neonatal cases, most patients had predisposing conditions. There was no difference in foci of bacteraemia, predisposing factors, treatment and outcome of disease. The overall mortality was 25%.
Zusammenfassung
Wir geben eine 2-Jahres-Übersicht über bakteriämische Episoden durch β-hämolysierende Streptokokken und stellen einen Fall von rezidivierenden Infektionen durch Streptokokken der Gruppe C,Streptococcus equisimilis, vor. Wir fanden 53 Episoden von Bakteriämie durch β-hämolysierende Streptokokken. Gruppe A war am häufigsten vertreten, es folgten die Gruppen B, G und C. Der Anteil nosokomialer Infektionen war in allen vier Gruppen gleich, das heißt 24% (Neugeborene ausgeschlossen). Das klinische Bild der durch Streptokokken der Gruppen C und G verursachten Infektionen war von den durch A Streptokokken verursachten nicht zu unterscheiden, doch waren Patienten, die durch Streptokokken der Gruppe G infiziert wurden, älter als Patienten mit Bakteriämie durch Streptokokken der Gruppe A. Bei Streptokokken der Gruppe A ließen sich häufiger eindeutige klinische Infektionsherde identifizieren als bei der Gruppe G. Abgesehen von den neonatalen Fällen hatten die meisten Patienten disponierende Faktoren. Hinsichtlich der Bakteriämieherde, disponierenden Faktoren, Behandlung und Krankheitsverlauf fanden sich keine Unterschiede. Die Gesamtsterblichkeit lag bei 25%.
