Biography

We investigate arboviruses that are transmitted in nature by hematophagous insects, specifically mosquitoes. Our research focuses on comparing infections of vector mosquitoes; Aedes aegypti, the Yellow Fever Mosquito and Ae. albopictus the Asian Tiger Mosquito with the non-vector mosquito, An. quadrimaculatis. Arboviruses transmitted by mosquitoes can and do result in human and/or veterinary infectious diseases. Infection of a mosquito host is prerequisite to biological transmission of such etiologic agents of disease. Currently, such infectious agents have an enormous economic impact worldwide.

 

Sindbis virus (SINV) is the prototype virus in the Togaviridae family and depends on a horizontal transmission pathway alternating between the vertebrate and invertebrate hosts. This scenario dictates that the virus replicates in two phylogenetically distinct cellular and biochemical milieu. It is this alternation of hosts that is believed to influence Alphavirus evolution. While virions produced in vertebrate and invertebrate cell culture are biologically equivalent, the cellular responses to infection and to various strains of SINV are quite different. We focus our efforts on understanding the infection process in the whole mosquito, a link in the chain of arbovirus transmission. By looking at long-term infection of two similar Aedine mosquitoes, we compare host responses to virus. We have focused our attention on virus in the salivary glands, gut and ovaries; three host organs of importance to virus transmission in nature. Additionally we are challenging mosquitoes with different SINV variants in order to eke-out successful persistent genotypes. Most recently we are analyzing mosquito response to insecticides following SINV infection. In the current global-climate of emerging and re-emerging diseases, investigations into the basic biology/virology of arboviruses will further efforts to combat mosquito-borne infectious diseases.

 

Currently, we are challenging mosquitoes with GFP-SINV and comparing the infection transit in vector (Aedine) and non-vector (Anopheline) mosquitoes. Additionally, our goals are to further investigate the intricacies of infection and escape barriers between these two genera. What are the tissue-level involvement(s) that compose a vector verses a non-vector?
