Rabies transmission by nonbite route.

摘要: TWO PERSONS who entered Frio Cave, a large limestone cavern near Uvalde, Tex., where rabid bats had been identified, subsequently died of laboratory-confirmed rabies (.1,2). One death occurred in 1956, the other 1958. Both men were reliable observers and early their illness, while still conscious alert, both denied knowledge being bitten by or mammals. These observations suggested possibility some nonbite mode transmission rabies, at lea.st under atmospheric conditions Cave caves similarly inhabited millions bats. In 1960 1961, three experiments undertaken to test this hypothesis. Several varieties wild carnivorous animals, including foxes, coyotes, opossums, raccoons, ringtails (cacomistles), skunks, as well domestic dogs cats, exposed cages for periods 7 30 days. Special efforts made, particularly third experiment, exclude all exposure bites animals arthropods. first beginning July 8, 1960, 13 carnivores (2 dogs, 2 ringtails, gray 1 striped skunk), each confined separately metal 1by 2-inch mesh cages, placed bat-occupied room within Cave. Previously caged isolation from 9 21 months, presumably ruling out incubation disease prior cave. Serums collected before experiment negative
