| a new species of rhabdias from lungs of the wood frog, rana sylvatica, in north america: the last sibling of rhabdias ranae? | rhabdias bakeri n. sp. is described from specimens found in lungs of the wood frog, rana sylvatica, from north dakota. the new species has previously been mistakenly identified as rhabdias ranae walton, 1929, a common parasite of the leopard frog, rana pipiens. the new species differs from r. ranae and rhabdias joaquinensis ingles, 1935 by the shape and size of pseudolabia, shape and size of buccal capsule, and wider esophageal bulb. molecular analysis based on the partial sequences of nuclear 1 ... | 2006 | 16884011 |
| co-occurrence of haematoloechus complexus and rhabdias joaquinensis in the plains leopard frog from nebraska. | species of haematoloechus and rhabdias both are ubiquitous lung parasites of frogs, yet surprisingly little research has been conducted on the interactions between these worms. in a small nebraska stream, 256 rhabdias joaquinensis and 225 haematoloechus complexus were found in the lungs of lithobates (=rana) blairi. thirty-six of the 44 (82%) frogs were co-infected with h. complexus and r. joaquinensis whereas 5 (11%) frogs were infected with only 1 species and 3 (7%) frogs were uninfected. test ... | 2013 | 23116463 |
| host specificity of north american rhabdias spp. (nematoda: rhabdiasidae): combining field data and experimental infections with a molecular phylogeny. | lungworms of the cosmopolitan genus rhabdias are among the most common parasites of amphibians and squamate reptiles. the present study used experimental infections, field studies, and a molecular phylogeny to determine the host specificity of 6 rhabdias spp. that infect snakes and anurans from north america. the molecular phylogeny suggests rhabdias ranae from nebraska and mississippi may represent separate, cryptic species. in addition, the phylogeny strongly supports separate clades for anura ... | 2013 | 22988815 |
| composition and structure of helminth communities of the salamanders, aneides lugubris, batrachoseps nigriventris, ensatina eschscholtzii (plethodontidae), and taricha torosa (salamandridae) from california. | component helminth communities of aneides lugubris (n=31), batrachoseps nigriventris (n=63), ensatina eschscholtzii (n=30), and taricha torosa (n=68) from california were determined. the compound helminth community consisted of 1 species of cestode, bitegmen gerrhonoti and 6 species of nematodes, batracholandros salamandrae, cosmocercoides variabilis, falcaustra pretiosa, megalobatrachonema gigantica, oswaldocruzia pipiens, and rhabdias joaquinensis. the least diverse infracommunities were assoc ... | 1998 | 9576495 |
| ecological factors responsible for the geographic distribution of rhabdias joaquinensis: where do lungworms infect anurans in nature? | the lungworm rhabdias joaquinensis (nematoda: rhabdiasidae) is a common parasite of anurans in eastern nebraska, yet absent from the same hosts in western nebraska. this study investigated the ecology of the lungworm's free-living stages that reside in host feces and surrounding soils to establish the worm's free-living niche in eastern nebraska. using a comparative method, this study also investigated the absence of lungworms in western nebraska's sandhills. soil composition, moisture, and temp ... | 2016 | 26666887 |
