title: SPORADIC OCCURRENCE OF ECHO VIRUS TYPES 27 AND 31 ASSOCIATED WITH ASEPTIC MENINGITIS IN ONTARIO.
abstract: The sporadic occurrence of Echo virus types 27 and 31 in association with aseptic meningitis during the enterovirus seasons in Ontario in 1959 to 1962 is reported.The etiological significance of both of these isolates was verified by demonstration of type-specific serological response in meningitis patients. Echo 27, which up to now has not been encountered in association with human illness, could be added to the list of viral agents capable of causing aseptic meningitis. Isolation of Echo 31 from cerebrospinal fluid provides definite proof of the etiological significance of this virus in cases of aseptic meningitis.
