Fasciola hepatica eggs were found in 37.1% (23/62) of the samples. Positive samples were found in six CUs (75%), three CUs located in the southern region of the state and three others in the metropolitan region of the capital city of Vitória. Identification of Fasciola hepatica eggs collected from capybara fecal samples were based on morphology, and confirmed using molecular methods. Our results suggest that capybaras may serve as a wild reservoir host for F. hepatica, possibly contributing to the epidemiology and geographic range expansion of this zoonotic parasite across its vast range of distribution in South America. Forty percent of the world's population live in areas where they are at risk from dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. Dengue viruses are transmitted primarily by the mosquito Aedes aegypti. In Cali, Colombia, approximately 30% of field collected Ae. aegypti are naturally refractory to all four dengue serotypes. Use RNA-sequencing to identify those genes that determine refractoriness in feral mosquitoes to dengue. This information can be used in gene editing strategies to reduce dengue transmission. We employed a full factorial design, analyzing differential gene expression across time (24, 36 and 48 h post bloodmeal), feeding treatment (blood or blood + dengue-2) and strain (susceptible or refractory). Sequences were aligned to the reference Ae. aegypti genome for identification, assembled to visualize transcript structure, and analyzed for dynamic gene expression changes. A variety of clustering techniques was used to identify the differentially expressed genes. We identified a subset of genes that likely assist dengue entry and replica
