Xenodiagnosis: use of mosquitoes for the diagnosis of arboviral infections.
The arboviruses have a worldwide distribution and, mosquitoes and ticks contribute principally in their transmission. In the last two decades, arboviral diseases have been recognised due to their resurgence and spread in newer geographic areas. Surveys to determine the prevalence of arboviruses in any region largely depend on the isolation attempts from the arthropods along with the serosurveys. Xenodiagnosis means use of insects for the diagnosis of infectious diseases affecting human being. The present communication discusses the application of mosquitoes for propagation and assays of arboviruses, the technique of mosquito inoculation and importance of xenodiagnosis.
