Fasciolosis, caused by the trematode Fasciola hepatica, is a zoonosis of economic importance in livestock that is emerging as a chronic disease in humans. The intermediate hosts are lymnaeid snails, in which diagnosis of infection is traditionally based on cercarial shedding, tissue sectioning and crushing. We developed a PCR assay for the sensitive and specific detection of F. hepatica in fiel...
Background. Fasciolosis is one of the most common zoonoses in world, caused by trematode Fasciola hepatica L. This helminthiasis leads to significant economic damage animal husbandry and can pose a direct threat human health. Today, context climate change, detailed knowledge biological characteristics F. circulation will make it possible predict outbreaks fasciolosis on farms detail plan effec...
ABSTRACT: Fascioliasis is a zoonosis of global distribution caused by the parasitic trematode Fasciola spp. Infection in humans can occur areas endemic for animal fascioliasis, suggesting need studies on this parasitosis and its determinants. This exploratory study aimed to analyze spatial bovine fascioliasis state Santa Catarina, Brazil, based cases notified between 2015 2017 abattoir, located...
1. Ecologists often measure the biomass and productivity of organisms to understand the importance of populations and communities in the flow of energy through ecosystems. Despite the central role of such studies in the advancement of freshwater ecology, there has been little effort to incorporate parasites into studies of freshwater energy flow. This omission is particularly important consider...
Methods We extracted distributional data for 564 freshwater trematodes across 25 biogeographical regions in Europe from the Limnofauna Europaea and used multiple regression analyses to test for correlations between the diversity of definitive (vertebrates) or first intermediate (gastropods) hosts and that of trematodes, and for latitudinal gradients in trematode diversity. In particular, we inv...
Road disturbances can influence wildlife health by spreading disease agents and hosts or by generating environmental conditions that sustain these agent and host populations. I evaluated field patterns of trematode infections in snails inhabiting ponds at varying distances from the Dalton Highway, a wilderness road that intersects northern Alaska. I also assessed the relationships between trema...
A survey of trematode larvae in the fresh water snail, Bithynia goniomphalos in the main water reservoir of Huai Thalaeng district, Nakhon Ratchasima Province, Thailand, was conducted. The study site is in an area with a high prevalence of Opisthorchis viverrini infection. Malacological samplings were made during the year 2000 to study the prevalence and intensity of infection. Parasitological ...
Trematodes of Audouin 3 gull, La rus audouinii (Aves, Laridae), from Chafarinas lslands (W Mediterranean).-A survey was carried out on the trematode fauna of Larus audouinii Payraudeau, 1826 (Aves, Laridae) in the Alboran Sea, south-western Mediterranean. A total of 10 trematode species was found: Sch/josomaatinae gen. sp., Ornithobilharzia sp., Pachytrerna calculus, Renico/a lar( Brachylecithu...
