Cerebrospinal Meningitis. The Use of Sulphonamide Derivatives in Prophylaxis

_~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~IDCLJI-~A Type 28, a Grotup A streptococcus not belonging to any known type.and a Type 14 were implicated.Tyvpe 28.-El and FM had this streptococcus for a short while.FM was at the time severelv infected with Staph.atureuis, B!act. coli, Strep.viridains.and an organism resembling Proteuts mielanovogenes (Miles and Halnan.1937).and the Type 28 had no observable effect.In El (and in FJ, see below) the appearance of the streptococcus sharply retarded the healing of an otherwise healthy wound containing only a little Staphi.atureus.Group A (U}.-The untypable Group A infected FJ. and was responsible for the second of HT's hospital infections.There was no evidence of ill effect in HT.These two uin- typable A's are being investigated.If they prove to be sero- logically identical we might'presume a cross-infection between HT and FJ, whose beds were only a few feet apart, for there were no other untypable A's in wounds or throats at the time.Tvpe 14.-SD first yielded Type 14 from a slowly healing
