| observations on the bionomy of allocreadium isoporum (looss, 1894) (trematoda: allocreadiidae). | from october 1985 until july 1987, the bionomy of the trematode allocreadium isoporum (looss, 1894) was studied in the rokytná river (the danube basin), czechoslovakia. while clams of the genera sphaerium scopoli and pisidium pfeiffer apparently serve as its first intermediate hosts, mayfly larvae ephemera danica müll. were found (prevalence 8%, intensity 1-5 metacercariae per mayfly) to be the only second intermediate host of a. isoporum in the locality. the most important definitive host is ch ... | 1992 | 1644360 |
| comparison of the developmental stages of some european allocreadiid trematode species and a clarification of their life-cycles based on its2 and 28s sequences. | genetic data were used to examine the diversity in some allocreadiid trematodes. nuclear ribosomal dna (its2 and partial sequences of 5.8s and 28s) was sampled from sexual adult and 'larval' stages. from these and previous reference datasets phylogenetic trees were constructed. the results uncovered genetically distinct lineages within bunodera luciopercae (müller, 1776), suggesting that the two palaearctic subspecies, b. l. luciopercae and b. l. acerinae roitman & sokolov, 1999, and nearctic b. ... | 2010 | 20532848 |

| endoparasites of chub (leuciscus cephalus) in two rivers of the abruzzo region of italy. | the relationship between communities of chub endoparasites (leuciscus cephalus) fished in the orta and pescara rivers in the abruzzo region of italy, and the quality of the water in which they are caught, were studied in surveys designed to evaluate the feed quality of fish in the inland waters of the abruzzo. samples were taken monthly from october 2000 to september 2001 in the orta river (buscesi district) and the pescara river (near the villareia bridge); a total of 86 chub were caught. durin ... | 2006 | 20429064 |
| comparative karyological analysis of three members of allocreadiidae (digenea): taxonomic and phylogenetic implications. | chromosome number and morphology were studied in three allocreadiid species from mitotic metaphases of intramolluscan stages using karyometric analysis. bunodera luciopercae has a diploid number 2n=14, with two large pairs of metacentrics, one pair of submeta-subtelocentrics, and four pairs of acrocentrics. karyotype of allocreadium isoporum, 2n=14, with two large pairs of metacentrics and five pairs of acrocentrics was recognized to be closely related to that of b. lucioperca. the most conspicu ... | 2008 | 18612648 |
