Abstract

The minimal intestinal dose of an enzootic strain of Venezuelan encephalitis (VE) virus for mosquitoes caught at a marsh habitat of VE virus in Guatemala was less than five plaque forming units (pfu) of virus. Ingestion of this dose of virus in blood of viremic hamsters resulted in transmission of virus to other hamsters. This low intestinal threshold of an enzootic strain of VE virus indicates that the natural Guatemalan population of can acquire VE virus from vertebrates that have viremia levels as low as 1,000–5,000 pfu/ml of blood, provided other factors do not limit virus interchange between mosquitoes and vertebrates.
