| gastroenteritis of infants in two canadian communities. | enteroviruses were isolated from 11 of 1391 rectal swabs collected from 1103 infants aged less than 2 years who were hospitalized in toronto, ontario, and new westminster, british columbia, between april 1966 and march 1969. viruses were recovered from 23 of 1231 rectal swabs obtained from 1076 age-matched control patients without gastroenteritis. the dominance of coxsackievirus and echovirus strains in toronto patients with and without gastroenteritis contrasted sharply to their extremely low i ... | 1970 | 4910892 |

| a genotypic characterization of enteroviral antigenic variants isolated in eastern canada. | antigenic variation within serotypes of enteroviruses can have a significant impact on the effectiveness of routine diagnosis by neutralization assays. the focus of this particular study was to initiate a genetic characterization of echovirus type 9 (e9) antigenic variants and nontypeable strains isolated in canada from 1991 to 1993. all variant strains were initially identified by the serological parameter of neutralization 'breakthrough' during conventional serotyping using the lim-benyesh-mel ... | 1999 | 10082385 |
| human surveillance for west nile virus infection in ontario in 2000. | the first reports of west nile virus (wnv) infection in the united states in 1999 prompted ontario to establish a surveillance protocol to monitor for the possible spread of the virus into the province. surveillance components included evaluation of dead birds, sentinel chickens, mosquito pools and human disease. we report the results of human surveillance in 2000. | 2002 | 11800244 |
