There is evidence that a specific type of allergic conjunctive-uveal granuloma reported from South India could be due to infection by a trematode parasite. In these patients, the histopathological examination of the eye reveals a zonal granulomatous inflammation with purulent material including structures with a distinct double-layer tegument, typical for a trematode worm. To investigate this f...

It is known from studies in a wide range of wild and domestic animals, including elephants, that parasites can affect growth, reproduction and health. A total of 458 faecal samples from wild elephants were analysed using a combination of flotation and sedimentation methods. Coccidian oocysts (prevalence 51%), and nematode (77%) and trematode (24%) eggs were found. Species were not identified, t...

Individual animals are often infected not only by different parasite species, but also by multiple genotypes of the same parasite species. Genetic relatedness among parasites sharing a host is expected to modulate their strategies of resource exploitation, growth and virulence. We experimentally examined the effects that genetic diversity and infection intensity had on host mortality, infectivi...

Coastal ecosystems are threatened by growing pressures related to global change. The evaluation of an ecosystem’s biodiversity and status is consequence increasing importance assess potentially undergone changes predict their future trajectory for management conservancy purposes. Biotic indicators sensitive ecosystem thus continuously sought for. Trematode parasite communities were examined as ...

Abstract Data on trematode life cycles, fish host distribution, transmission, and snail infection are reported in this review. European freshwater trematodes of the genus Sanguinicola (Aporocotylidae) remain an insufficiently studied group trematodes. Five species Aporocotylidae ( armata , S. inermis intermedia volgensis rutili ) Europe described. In addition, they have been found water bodies ...

Background: Dicrocoeliasis is caused by digenean trematode of Dicrocoelium dendriticum, small liver fluke, a hepatic parasitic disease in ruminants and human, throughout the world. D. dendriticum infection has been considered to be correlated with the economic and veterinary aspects. Objectives: The aim of the present study was to determine the prevalence and intensity of infection with D. dend...

Fasciola hepatica (FH) infection is endemic in South America, the Caribbean, Europe, and Asia. The population of southern Florida, with proximity to the Caribbean and South America, may be at risk. FH infection has acute and chronic stages. In the acute stage, the patient presents with fever, hepatomegaly, and abdominal pain. In the chronic stage, the trematode can invade the bile ducts resulti...

The effect of hydrocortisone on the development of BH strain of S. mansoni in B. glabrata snails is evaluated. Snails in a randomly chosen group were submitted to hydrocortisone during four days. In the second day of hydrocortisone exposure, the snails were exposed, each, to ten S. mansoni miracidia. Another group, not treated with hydrocortisone, was exposed to miracidia and observed in the sa...
