Infection[edit]
In September 1931, Joseph Lennox Pawan of Trinidad in the West Indies, a Government Bacteriologist, found Negri bodies in the brain of a bat with unusual habits. In 1932, Pawan first discovered that infected vampire bats could transmit rabies to humans and other animals.[8][9] For a brief history of some of the controversies surrounding the early discoveries relating to rabies in Trinidad, see the brief history by James Waterman.[10]
