| a molecular phylogenetic study of the genus ribeiroia (digenea): trematodes known to cause limb malformations in amphibians. | species of ribeiroia (trematoda: psilostomidae) are known to cause severe limb malformations and elevated mortality in amphibians. however, little is known regarding the number of species in this genus or its relation to other taxa. species of ribeiroia have historically been differentiated by slight differences among their larval stages. to better understand the systematics and biogeography of this genus and their potential relevance to the distribution of malformed amphibians, specimens identi ... | 2005 | 16419746 |
| morphological and its2 molecular characterization of ribeiroia cercariae (digenea: psilostomidae) from biomphalaria spp. (gastropoda: planorbidae) in northern argentina. | species of ribeiroia use planorbid snails as intermediate host. since there is little information about these digenean parasites in south america, we aimed to assess whether ribeiroia cercariae from 3 north argentina locations belonged to the same species and differed from ribeiroia cercariae described elsewhere. specimens were obtained from biomphalaria tenagophila and biomphalaria orbignyi (salta province), and biomphalaria occidentalis (corrientes province). morphological traits of cercariae ... | 2015 | 26075730 |
