Characterization of simian viruses isolated from wild cynomolgus monkeys

Twenty three strains of simian viruses isolated from nasopharyngeal swabs and respiratory tissues of cynomolgus monkeys showing mild symptoms of respiratory disorders were classified into three groups by their biological, serological and morphological characteristics. Thirteen strains classified as group 1 were judged to be enteroviruses. Four strains of group 2 and six strains of group 3 were identified as simian adenoviruses. Yields of the ten simian adenoviruses of groups 2 and 3 were compared in three continuous cell lines after several serial passages.
