“…Disease outbreaks are a growing threat to animal communities worldwide. The consequences of human activities, including habitat modification (North et al, 2015), climate change (Cohen et al, 2020) and animal rearing (Hernández et al, 2019) contribute to disease emergence in wild animal populations. Anthropogenic acceleration of disease spread in wildlife (e.g.…”

Cascading effects of a disease outbreak in a remote protected area

Disease outbreaks induced by humans increasingly threaten wildlife communities worldwide. Like predators, pathogens can be key top-down forces in ecosystems, initiating trophic cascades that may alter food webs. An outbreak of mange in a remote Andean protected area caused a dramatic population decline in a mammalian herbivore (the vicuña), creating conditions to test the cascading effects of disease on the ecological community. By comparing a suite of ecological measurements to pre-disease baseline records, we demonstrate that mange restructured tightly linked trophic interactions previously driven by a mammalian predator (the puma). Following the mange outbreak, scavenger (Andean condor) occurrence in the ecosystem declined sharply and plant biomass and cover increased dramatically in predation refuges where herbivory was historically concentrated. The evidence shows that a disease-induced trophic cascade, mediated by vicuña density, could supplant the predator-induced trophic cascade, mediated by vicuña behaviour, thereby transforming the Andean ecosystem.

Abstract The aim of the present study was to evaluate the state of knowledge about the helminthology of wild mammals in Argentine Patagonia and its link with the conservation of parasite species and biodiversity. To this end, the information included in the previously reported checklist of the helminths found in terrestrial wild mammals of Argentine Patagonia was completed and updated. The methodology used for the search was the same as that previously used, with slight modifications. Eighty-two species of mammals currently inhabit the region, and an additional six species are considered to have become extinct before the 20th century. The reports used to complete and update the information correspond to research done since 2015 to date. Considering the number of records analysed in the previously reported checklist and those of the current update, a total of 1918 helminthological reports for current Patagonian mammals and 2141 on mammal species that inhabited Patagonia before the 20th century were accounted for. It is important to point out that 41% of the 82 species of wild mammals currently inhabiting Patagonia have not been studied helminthologically; 38% of these without helminthological records are either threatened or do not have categorization, and 79% of mammals without helminthological studies have some degree of endemism. Therefore, in order to evaluate conservation priorities, the information about the parasitic richness in Patagonian wild mammals should be substantially increased, especially in those endangered or endemic.

Aspectos Generales del Perfil Proteómico del Echinococcus granulosus

MANTEROLA, C.; GARCÍA, N. & ROJAS, R. Aspectos generales del perfil proteómico del Echinococcus granulosus. Int. J. Morphol., 37(2): 773-779, 2019. RESUMEN: La información disponible referente a las características proteómicas del E. granulosus es escasa (no supera los 50 estudios publicados); y nos parece que la identificación proteómica, podría mejorar la comprensión de algunas características bioquímicas e inmunológicas de la Equinococosis Quística (EQ). De tal modo que el proteoma de E. granulosus aún no está bien descrito. Sólo existen reportes de algunas secuencias de proteínas. El objetivo de este manuscrito fue comentar algunos aspectos de la evidencia existente respecto de los estudios del perfil proteómico del E. granulosus. Se recomienda el estudio de al menos el quiste y su pared, el líquido hidatídico y la víscera del hospedero. Para ello, existen metodologías que han sido empleadas para estudiar las características proteómicas de la EQ. Entre ellas, destacan SDS-PAGE, electroforesis bidimensional combinada con Western Blot, inmunoanálisis, y espectrometría de masas mediante técnicas MALDI-TOF. Se han identificado una serie de proteínas en muestras de EQ. Algunas de ellas, asociadas a procesos inmunológicos, de gluconeogénesis, glucogenolisis y glucogénesis. Por otra parte, se ha documentado la liberación de exosomas al líquido hidatídico por parte de los protoescólex y la capa germinativa; estructuras en las que se han identificado factores de virulencia asociados con la supervivencia del quiste. No obstante lo anteriormente señalado, se requiere de múltiples estudios exhaustivos en la materia para comprender mejor la caracterización perfil proteómico del E. granulosus.
