Project 2: Trade-Off Project

The evolution of pathogen virulence is shaped, in part, by the trade-off between the level of pathogen replication, which determines instantaneous rate of transmission, and the duration of infection.  While most studies have focused on pathogen-induced mortality as the regulator of infection duration, we are testing how the innate immune response shapes the transmission-clearance trade-off for dengue virus and Zika virus in native and novel non-human primate hosts.  The results of this study will enhance our current understanding of the factors that shape virus evolution and our ability to predict virus emergence.

L’évolution de la virulence des agents pathogènes est en partie déterminée par le compromis évolutif entre le niveau de réplication de l’agent d’une part, qui détermine son taux de transmission instantanée, et la durée d’infection d’autre part. Alors que la plupart des études existantes évoquent la mortalité induite par l’agent pathogène comme un régulateur de la durée d’infection, nous nous intéressons quant à nous à la manière dont la réponse immunitaire innée peut être impliquée dans le compromis évolutif entre transmission et élimination. Nous étudions ici cette question pour les virus de la dengue et Zika chez des hôtes primates non-humains, pour des espèces que l’on retrouve infectées naturellement sur le terrain, mais également pour des espèces qui pourraient constituer de nouvelles populations d’hôtes. Les résultats de ce projet permettront d’accroitre notre compréhension des facteurs qui déterminent l’évolution des virus, et de ce fait notre capacité à prédire leur émergence.

 This study is a collaboration among Kathy Hanley, Nik Vasilakis (UTMB), Ben Althouse (NMSU and UW), Shannan Rossi (UTMB), Sasha Azar (Houston Methodist) and Hélène Cecilia (NMSU), with support from Brett Moehn (NMSU), Ivy Yu (NMSU) and Ruimei Yun (UTMB).

Project 3: An Early Warning System for VSV Emergence

Vesicular stomatitis virus (VSV) is a vector-borne pathogen of livestock that circulates endemically in the neotropics from southern Mexico to northern South America.  VSV emerges periodically into the US, causing outbreaks across the mountain west for one to three years before receding (https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/cattle-disease-information/vesicular-stomatitis-info).

The trigger for these outbreaks is unknown, and indeed many key aspects of VSV ecology remain to be discovered. Our team works as part of a larger USDA Grand Challenge project and with Mexico’s SENASICA to elucidate the key vectors for VSV transmission in an incursion region in southern New Mexico, USA as well as VSV transmission dynamics in its endemic region in Chiapas, Mexico.  We have also recently initiated studies of VSV occurrence in the “stepping stone” states of Jalisco and Chihuahua, Mexico.

 

El virus de la estomatitis vesicular (VSV) es un patógeno del ganado transmitido por vectores que circula endémicamente en el neotrópico desde el sur de México hasta el norte de América del Sur. El VSV surge periódicamente en los EE. UU. y provoca brotes en el oeste montañoso durante uno a tres años antes de retroceder (https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/cattle-disease-information /estomatitis-vesicular-info).

Se desconoce el desencadenante de estos brotes y, de hecho, aún quedan por descubrir muchos aspectos clave de la ecología del VSV. Nuestro equipo trabaja como parte de un proyecto USDA Grand Challenge más grande y con SENASICA de México para elucidar los vectores clave para la transmisión de VSV en una región de incursión en el sur de Nuevo México, EE. UU., así como la dinámica de transmisión de VSV en su región endémica en Chiapas, México. También hemos iniciado recientemente estudios de la ocurrencia de VSV en los estados de "trampolín" de Jalisco y Chihuahua, México.
