VESICULAR STOMATITIS VIRUS INFECTIONS IN PANAMANIAN PRIMATES AND OTHER VERTEBRATES1
Srihongse, S. (Gorgas Memorial Laboratory, P.O. Box 2016, Balboa Heights, Canal Zone). Vesicular stomatitis virus infections in Panamanian primates and other vertebrates. Amer. J. Epid., 1969, 90: 6976.A large scale survey for antibodies to vesicular stomatitis virus (Indiana type) in monkeys and other wild vertebrates was performed in different areas of Panama. Approximately 75% of 267 monkeys in Darien province were positive in neutralization (NT) tests whereas only 19% positive results were obtained from 383 monkeys collected near Panama City. Spider monkeys (Ateles spp.) showed the highest rate of NT antibodies to VSV-lndiana. A high incidence of complement-flxing (CF) antibodies was also demonstrated in Darien monkeys. NT tests in wild vertebrates other than monkeys showed a much higher rate in arboreal mammals than in ground-living animals. Two-toed sloths (Choloepus hoffmani) and tropical porcupines (Coendou rothschildi) were among arboreal mammals showing evidence of high VSV-lndiana rates. Virus isolation attempts from 1, 558 wild vertebrates were negative but a strain of VSV-lndiana was obtained from a worker on a cattle farm in Darien. Four of the sentinel monkeys exposed there showed rises in VSV-lndiana antibody titers, although virus isolation attempts from serial bleedings were negative. The findings above provide supportive evidence that monkeys and other arboreal mammals may be involved in VSV-lndiana cycles.
