| helminth associations in white-toothed shrews crocidura russula (insectivora: soricidae) from the albufera natural park, spain. | the helminths of 218 white-toothed shrews from 29 sites in 2 biotopes in the albufera natural park (valencia, spain) were examined from july 1990 to august 1991. an association analysis of helminths occurring at a prevalence of more than 4% was carried out for 4 species of cestodes located in the intestine (hymenolepis pistillum, h. scalaris, h. tiara, and pseudhymenolepis redonica) and 3 species of nematodes (pseudophysaloptera sp. located in the stomach, stammerinema rhopocephala larvae in the ... | 2004 | 15270101 |
| normal and aberrant mesocestoides tetrathyridia from crocidura spp. (soricimorpha) in corsica and spain. | abstract tetrathyridia of mesocestoides sp. were collected from the body cavities of the shrews (soricimorpha), crocidura russula in valencia, spain, and crocidura suaveolens on the mediterranean island of corsica, france. specimens were processed by routine microscopical and histological techniques, including examination with brightfield, phase-contrast, and differential-interference-contrast optics. most tetrathyridia occurred both clustered together inside host-derived fibrotic capsules, but ... | 2011 | 21612421 |
