PARÁSITOS GASTROINTESTINALES EN TAYASSU PECARI Y PECARI TAJACU DE VIDA LIBRE DE LA RESERVA DE LA BIÓSFERA Y TERRITORIO COMUNITARIO DE ORIGEN PILÓN LAJAS, BENI – BOLIVIA

Adult and immature gastrointestinal parasites from 47 tayassuids (27 Tayassu pecari and 20 Pecari tajacu) hunted for human consumption at the Pilon Lajas Biosphere Reserve and Indigenous Territory, Bolivia, were identified. Parasite eggs and oocysts were identified by fecal flotation and sedimentation, while adult parasites were obtained from the digestive tract and collected through the Travassos method for morphometric identification. Four nematode species (Texicospirura turki, Monodontus aguiari, Eucyathostomum dentatum and Ascaris sp.), one cestode (Monienzia benedeni), one trematode (Stichorchis giganteus) and Eimeria spp. oocysts were detected. Parasites of the Ascaris genera were detected only in T. pecari while the rest of the parasites were found in both tayassuid species. This study provides the first report for these parasites in peccaries from Bolivia. Given the close contact between Amazon inhabitants and tayassuids, and considering the zoonotic nature of Ascaris infections, further investigations into potential peccary to human transmission are warranted.La colecta de muestras biológicas de 47 tayassuidos (27 Tayassu pecari y 20 Pecari tajacu) cazados para consumo familiar en la Reserva de la Biosfera y Tierra Comunitaria de Origen Pilón Lajas, Bolivia, permitió la identificación de formas parasitarias inmaduras y adultas del aparato digestivo de ambas especies de ungulados. La identificación de huevos y ooquistes parasitarios se realizó empleando los métodos cualitativos de flotación y sedimentación para el análisis de heces, mientras que los parásitos adultos fueron recuperados del tracto digestivo y colectados mediante el método de Travassos para su identificación por morfometría. Cuatro especies de nematodos (Texicospirura turki, Monodontus aguiari, Eucyathostomum dentatum y Ascaris sp.), un céstodo (Moniezia benedeni), un tremátodo (Stichorchis giganteus) y ooquistes del género Eimeria spp. fueron identificados. Parásitos del género Ascaris sp. fueron detectados únicamente en T. pecari y los demás parásitos se registraron en ambas especies de tayassuidos. Los parásitos en este estudio se constituyen en nuevos reportes para ambas especies de ungulados en Bolivia. Dado el estrecho contacto existente entre los habitantes de comunidades amazónicas y tayassuidos, y dadas las características zoonóticas de las infecciones por Ascaris, se sugiere investigar la potencial tranmisibilidad de este grupo parásito entre pecaríes y personas

Implementing One Health approaches to confront emerging and re-emerging zoonotic disease threats: lessons from PREDICT.

Recurring outbreaks of emerging and re-emerging zoonoses, such as Ebola virus disease, avian influenza, and Nipah virus, serve as a reminder that the health of humans, animals, and the environment are interconnected and that early response to emerging zoonotic pathogens requires a coordinated, interdisciplinary, cross-sectoral approach. As our world becomes increasingly connected, emerging diseases pose a greater threat, requiring coordination at local, regional, and global levels. One Health is a multisectoral, transdisciplinary, and collaborative approach promoted to more effectively address these complex health threats. Despite strong advocacy for One Health, challenges for practical implementation remain. Here we discuss the value of the One Health approach for addressing global health challenges. We also share strategies applied to achieve successful outcomes through the USAID Emerging Pandemic Threats Program PREDICT project, which serve as useful case studies for implementing One Health approaches. Lastly, we explore methods for promoting more formal One Health implementation to capitalize on the added value of shared knowledge and leveraged resources
