Isolation, detection and characterization of swine hepatitis E virus from herds in Costa Rica
(Taylor & Francis, 2008)Although swine HEV isolates from North America, Europe, and Asia have been genetically characterized, little is known about the strains presumed to be circulating in Latin America. In this study, seven commercial swine ... -
Molecular, morphological and histopathological evidence of Spirometra mansoni in wild and domestic animals from Costa Rica
(Elsevier Science B.V, 2024-04-30)Spirometra mansoni is a diphyllobothroid cestode and one of the causing agents of sparganosis, a zoonotic foodborne and waterborne infection in humans. This parasite has an indirect life cycle with domestic and wild canids ... -
Passive epidemiological surveillance in wildlife in Costa Rica identifies pathogens of zoonotic and conservation importance
(PLoS ONE, 2022-09-26)Epidemiological surveillance systems for pathogens in wild species have been proposed as a preventive measure for epidemic events. These systems can minimize the detrimental effects of an outbreak, but most importantly, ... -
Phenotypes controlled by the Brucella abortus two component system BvrR/BvrS are differentially impacted by BvrR phosphorylation
(Frontiers Media S.A, 2023-05-10)Brucella abortus is a zoonotic pathogen whose virulence depends on its ability to survive intracellularly at the endoplasmic reticulum derived compartment. The two-component system BvrR/BvrS (BvrRS) is essential for ... -
