Case of bacteraemic cellulitis by a non-haemolytic strain of Streptococcus pyogenes

Scand J Infect Dis. 2007;39(3):262-4. doi: 10.1080/00365540600868362.


Erysipelas and bacteraemia with what initially was diagnosed as a non-haemolytic streptococcus is reported. As neither colony morphology nor clinical picture was characteristic of non-haemolytic streptococci, the isolate was sent to a reference laboratory. 16S rRNA sequencing and phenotypic characterization identified the strain as a streptolysin S-deficient S. pyogenes..
