V. Evaluation of Cross-Immunity against Type 1 Dengue Fever in Human Subjects Convalescent from Subclinical Natural Japanese Encephalitis Virus Infection and Vaccinated with 17D Strain Yellow Fever Vaccine
Four of 46 weak and nonflying Mexican free-tail bats (Tadarida brasiliensis mexicana) captured in Frio Cave, Uvalde County, Texas, were found to be infected with bat salivary gland virus. One of these four bats survived and was maintained in a nonhibernating state in the laboratory, and bat salivary gland virus was recovered from the saliva on 10 occasions over a period of 309 days after the bat was captured.
