A total of 611 preserved adult Metagonimus spp. specimens recovered from 32 of 53 Japanese water shrews (Chimarrogale platycephala) that had previously been collected in Aomori Prefecture between June 1994 and August 1996, were examined in this study. Morphological examination revealed that 603 of these flukes were identical to M. hakubaensis Shimazu, 1999, and that the others were M. takahashi...

Geographic variability in abundance can be driven by multiple physical and biological factors operating at multiple scales. To understand the determinants of larval trematode prevalence within populations of the marine snail host Littorina littorea, we quantified many physical and biological variables at 28 New England intertidal sites. A hierarchical, mixed-effects model identified the abundan...

The objective of this study was to perform a malacological assessment at the Ibirité reservoir watershed in the metropolitan region of Belo Horizonte (Minas Gerais) and to evaluate the natural infestation rate of Biomphalaria straminea (Gastropoda: Planorbidae) by Schistosoma mansoni (Platyhelminthes: Trematoda) and Chaetogaster limnaei (Oligochaeta: Naididae). The samples were collected from J...

The paper presents the results of works on preparation of a proper museum collection of parasitic helminths gathered by the Polish scientists and dispersed in various scientific institutions. The collection composed of 11 author's collections and a special collection of available typical series of species described by the Polish authors has been deposited in the Museum of Natural History of Wro...

High performance thin layer chromatography (HPTLC) was used to determine the phospholipid and sphingolipid profiles in the feces of BALB/c mice infected with Echinostoma caproni (Trematoda) versus uninfected controls. Lipids extracted from fecal samples with chloroform-methanol, 2:1, were separated on silica gel HPTLC plates developed in chloroformmethanol-water, 65:25:4. Densitometric analysis...
