Trematode Parasites of Man
This little pamphlet is a United States Government publication, the seventeenth bulletin of the Hygenic Laboratory. It consists of 52 pages of letterpress with 88 excellent illustrations, and in addition a bibliography and two indices. It has been written in response to recent requests to the author for information in regard to the trematodes which are parasitic to man, and is offered as a read...
متن کاملControls of spatial variation in the prevalence of trematode parasites infecting a marine snail.
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...
متن کاملBiogeographical patterns of marine larval trematode parasites in two intermediate snail hosts in Europe
Species generally show recognizable large-scale biogeographical patterns in distribution and abundance (Cox & Moore, 2005; Lomolino et al., 2006). Many species exhibit similar distributions depending on similar regional conditions, a phenomenon allowing the detection of distinct faunal provinces and regions (Briggs, 1995; Cox & Moore, 2005; Lomolino et al., 2006). Whereas free-living species ha...
متن کاملContrasting mtDNA diversity and population structure in a direct-developing marine gastropod and its trematode parasites.
The comparative genetic structure of hosts and their parasites has important implications for their coevolution, but has been investigated in relatively few systems. In this study, we analysed the genetic structure and diversity of the New Zealand intertidal snail Zeacumantus subcarinatus (n = 330) and two of its trematode parasites, Maritrema novaezealandensis (n = 269) and Philophthalmus sp. ...
متن کاملThe Larvae of Some Monogenetic Trematode Parasites of Plymouth Fishes
The Order Monogenea of the Class Trematoda contains (Sproston, 1946) upwards of 679 species, but in only twenty-four of these species has a larval form been described. Of these larvae, fourteen belong to adults that parasitize fresh-water fishes, amphibians or reptiles, and ten to adults that parasitize marine fishes. Udonella caligorum is known (Sproston, 1946) hot to have a larval stage in it...
