§ Mr. GROVESasked the Minister of Health how many types of haemolytic streptococcus have been identified; whether particular types are assigned to particular diseases; and what is the official explanation of the fact that four different types of the haemolytic streptococcus have been found in cases of acute tonsilitis in Essex during 1934?
Sir H. YOUNGThe answer to the first part of the question is that up to the present 28 different types of haemolytic streptococcus have been identified. As regards the second part, the answer is in the negative, but I am advised that certain types are more frquently associated with particular clinical manifestations, for instance, scarlet fever. As regards the third part, I am advised that nearly all the types of the streptococcus identified can cause acute inflammation of the throat and tonsils.
