West Nile virus: a serosurvey of ranid frogs across Illinois.

Research output: Contribution to journalArticlepeer-review

Abstract

West Nile virus (WNV) has been isolated in many amphibian feeding species of mosquitoes. Based on this evidence, this study sought to evaluate if amphibians and reptiles, in addition to birds and mammals, play a role in the transmission of West Nile virus (WNV). Bullfrogs, Leopard frogs, and Green frogs were collected from selected sites across the state of Illinois. Blood, and in some individuals tissue, was collected from all individuals (n=239) and tested for the presence of WNV antibodies using epitope-blocking enzyme-linked immunosorbent assay (ELISA). No WNV antibody positive frogs were found of the 239 tested. This suggests that frogs may not build up immunity to the virus. However, the results of this study do not address whether frogs die or become refractory from exposure to the virus, indicating that further research is needed to address the role amphibians play in the WNV transmission cycle.
