• External reinfection of a fungal pathogen does not contribute to pathogen growth

      DiRenzo, Graziella V.; Tunstall, Tate S.; Ibáñez, Roberto; deVries, Maya S.; Longo, Ana V.; Zamudio, Kelly R.; Lips, Karen R. (2018)
      Chytridiomycosis is an emerging infectious disease of amphibians caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), which has led to devastating declines in amphibian populations worldwide. Current theory predicts that Bd infections are maintained through both reproduction on the host’s skin and reinfection from sources outside of the host....
    • Lead in ammunition: A persistent threat to health and conservation

      Johnson, C. K.; Kelly, T. R.; Rideout, Bruce (2013)
      Many scavenging bird populations have experienced abrupt declines across the globe, and intensive recovery activities have been necessary to sustain several species, including the critically endangered California condor (Gymnogyps californianus). Exposure to lead from lead-based ammunition is widespread in condors and lead toxicosis presents an immediate threat to condor recovery, accounting for the highest proportion of adult mortality….
    • Molecular epidemiology of Trypanosomatids and Trypanosoma cruzi in primates from Peru

      Aysanoa, Esar; Mayor, Pedro; Mendoza, A. Patricia; Zariquiey, Carlos M.; Morales, E. Angelo; Pérez, Jocelyn G.; Bowler, Mark; Ventocilla, Julio A.; González, Carlos; Baldeviano, G. Christian; et al. (2017)
      We determined the prevalence rate and risk of infection of Trypanosoma cruzi and other trypanosomatids in Peruvian non-human primates (NHPs) in the wild (n = 126) and in different captive conditions (n = 183). Blood samples were collected on filter paper, FTA cards, or EDTA tubes and tested using a nested PCR protocol targeting the 24S? rRNA gene....
    • Survey of Plasmodium spp. in free-ranging neotropical primates from the Brazilian Amazon region impacted by anthropogenic actions

      Bueno, Marina G.; Rohe, Fabio; Kirchgatter, Karin; Di Santi, Silvia M. F.; Guimarães, Lilian O.; Witte, Carmel L.; Costa-Nascimento, Maria J.; Toniolo, Christina R. C.; Catão-Dias, José Luiz (2013)
      This study investigated Plasmodium spp. infection in free-ranging neotropical primates from Brazilian Amazon regions under the impact of major anthropogenic actions. Blood samples from 19 new world primates were collected and analyzed with microscopic and molecular procedures. The prevalence of Plasmodium infection was 21.0% (4/19) and PCR positive samples were identified as P. brasilianum. Considering the social-economic changes that the Amazon is facing, the prevalence of P. brasilianum infection highlights the necessity to closely monitor the movement of both human and non-human primate populations, in order to mitigate pathogen exposure and the introduction of new agents into previously naïve areas.
