Helminth parasites are reported for the first time from northern spotted owls. Seventy-one percent of a sample of Strix occidentalis caurina from western Oregon was infected. Nematodes (Porrocaecum depressum, Capillaria falconis, Microtetrameres sp. and Synhimantus hamatus) were the most prevalent parasites although cestodes (Paruterina rauschi) and acanthocephalans (Centrorhynchus conspectus) ...

Various processes can generate associations between the larvae of different helminth species in their fish intermediate or paratenic host. We investigated the pairwise associations among larval helminth species in eight different fish populations, using two different coefficients of associations, in order to determine in what situations they are strongest. All helminth species included use the ...

The sea lamprey Petromyzon marinus, which is among the most phylogenetically ancient vertebrates, is a hematophagous ectoparasite that feeds on vertebrates and is considered vulnerable in Europe but is a pest in the North American Great Lakes. We conducted a literature review of helminth parasites of P. marinus and investigated postmetamorphic lampreys sampled in rivers and northeast Atlantic c...

The study of parasite body size is an important approach to understand the different patterns of helminth community structure, once it is usually analysed using only numerical descriptors which do not capture size heterogeneity among parasite species. In the present study, we compared the pattern in the helminth community of three sympatric wild rodent species Akodon cursor, A. montensis and Ol...

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%), brachylaemuserinacei(2.0%) and hymenolepiserinacei(16.0%). ...

One-hundred twelve amphibians, including 51 blue-spotted salamanders, Ambystoma laterale, 30 eastern American toads, Bufo americanus americanus, and 31 northern leopard frogs, Rana pipiens, were collected during April-October 1996 from Waukesha County, Wisconsin and examined for helminth parasites. The helminth compound community of this amphibian assemblage consisted of at least 10 species: 9 ...

The article presents the comparative analysis of helminth fauna sympatric bat species, Myotis mystacinus and M. brandtii (Chiroptera, Vespertilionidae), in Samarskaya Luka National Park (Russia). Twelve species parasites were recorded both 2005–2007, including nine Trematoda, one Cestoda, two Nematoda. All these 12 noted brandtii. included a slightly depleted parasite being represented by seven...

Wastewater treatment is a widely used health protection measure that can be applied to control the transmission of wastewater-related infectious diseases communities exposed wastewater. This study determined efficiency three full-scale constructed wetlands (CWs) in removing pathogenic parasites and fecal coliform (FC) bacteria from samples were collected CW systems located Dar es Salaam Iringa ...
