To explore the role of viruses in the etiology of diarrhea in colony-reared monkeys, direct electron microscopy, the fluorescent virus precipitin test and cell culture inoculation were used to examine the stools of monkeys with and without diarrhea. The animals were predominantly rhesus with a few macaques of other species, and included infants, juveniles and adults. Adenoviruses were isolated from a higher proportion of specimens from rhesus monkeys with diarrhea (73% of specimens from infants and 78% of specimens from juveniles and adults) than from control monkeys without diarrhea (22% of specimens from infants and 26% of specimens from juveniles and adults). SV 20 was the most frequently isolated simian adenovirus type; SV 17 and SV 32 also were recovered. Noncultivable adenoviruses detectable only by electron microscopy were not seen. Although adenovirus excretion was associated with diarrhea, the causal role of adenoviruses was difficult to assess. When serial specimens from animals with chronic or intermittent episodes of diarrhea were examined, sequential infections with different viruses were found to be common. Rotaviruses were detected by electron microscopy and isolated in cell cultures from two infant rhesus monkeys with diarrhea. However, the low detection rate, together with negative serologic data on 40% of infant monkeys with diarrhea, suggested that rotaviruses were not the major cause of gastroenteritis in the monkeys under study. |
