Climate change is occurring rapidly at high latitudes, and subsequent changes in parasite communities may have implications for hosts including wildlife and humans. Waterfowl, in particular, harbor numerous parasites and may facilitate parasite movement across broad geographic areas due to migratory movements. However, little is known about helminth community structure of waterfowl at northern ...

AIM Intestinal parasitic diseases are commonly accompanied with diarrhoeal symptoms and allergic reactions. Eosinophilia occurs as a result of IL-5 synthesized from Th2 cells during allergic reactions. IL-5 acts as a factor activating eosinophils. The aim of this study was to compare the IL-5 cytokine measurements in serum samples and cell cultures. And also to compare eosinophilia observed in ...

The fragmentation of howler monkeys (Alouatta) habitat to make room for the urban environment, allows spread zoonotic diseases. objective this study was verify occurrence helminth eggs in feces Alouatta guariba clamitans 2 biological reserves located Porto Alegre - RS. Lami and São Pedro, respectively, presented gastrointestinal parasites superfamilies Strongyloidea; Oxyuroidea, Trichuroidea Rh...

Gastrointestinal nematode infections pose a major threat to small ruminant production. is a helminth parasite that feeds on blood of small ruminant animals and causes anaemia, anorexia, loss of condition, and eventual death of the host animal. The parasite is particularly found in tropical and subtropical regions worldwide [1]. In Nigeria and most developing countries, parasitic helminths cause...

From April 2009 to December 2011, 44 dead hedgehogs (Erinaceus europaeus) were collected incidentally from areas of Urmia, Iran. The overall prevalence of helminth infections was 95.0%. Specific parasites and their prevalences were: Physalopteraclausa(93.0%), Crenosoma striatum (61.0%), Capillariaaerophila(9.0%), Capillariasspp.(4.0...

Mapping and modelling helminth infections in cattle and sheep in Europe through advanced geospatial research was one of the main task of GLOWORM, a three year project (2012-2014) funded under the European Commission's (EC) seventh framework programme (FP7). Liver flukes as Fasciola hepatica and gastrointestinal nematodes, such as Haemonchus contortus were chosen for the project since these para...

Eosinophilic leukocytes function in host protection against parasitic worms. In turn, helminthic parasites harbor specific molecules to evade or paralyze eosinophil-associated host immune responses; these molecules facilitate the migration and survival of parasitic helminths in vivo. This competition between eosinophil and worm leads to stable equilibria between them. An understanding of such d...

Knowledge concerning the taxonomy and biology of species of Acanthocephala, helminth parasites of the helminth species of the phylum Acanthocephala, parasites of lizards in Brazilian Amazonia, is still insufficient, but reports of Acanthocephala in reptiles are becoming increasingly common in the literature. Cystacanth-stage Acanthocephalan larvae have been found in the visceral peritoneum duri...

INTRODUCTION Few studies have described the risk factors of intestinal parasitic infections in the Amazon. METHODS A cross-sectional survey was performed in a City of the State of Amazonas (Brazil) to estimate the prevalence of intestinal parasites and determine the risk factors for helminth infections. RESULTS Ascaris lumbricoides was the most prevalent parasite. The main risk factors dete...

Protozoan cysts and helminth eggs preserved in a coprolite from the Early Cretaceous Bernissart Iguanodon shaft in Belgium demonstrate that representatives of 3 phyla parasitized dinosaurs by that period. These fossil parasite stages are described and their possible effect on dinosaurs discussed. These findings represent the earliest fossil records of protozoan and helminth parasites of terrest...
