S. Pournaras et al., Genetic relatedness of group A streptococci of the newly designated serotype M90 causing a food-borne outbreak and sporadic infections, EPIDEM INFE, 125(2), 2000, pp. 299-301
Twenty-six isolates of the newly designated M90 serotype group A Streptococ
cus (GAS) from a large food-borne outbreak of pharyngitis in Greece and six
M90 sporadic isolates from UK, were typed by pulsed-field gel electrophore
sis (PFGE). Twenty-four outbreak isolates were identical and two closely re
lated. The Greek isolates were possibly related with one UI( isolate, while
other sporadic isolates exhibited distinct PFGE profiles from the former i
solates.
