| spatial and temporal distribution of the asian fish tapeworm bothriocephalus acheilognathi (cestoda: bothriocephalidea) in the rio grande (río bravo del norte). | recent collections of the asian fish tapeworm bothriocephalus acheilognathi in the rio grande have raised concern about the potential impacts on rio grande endemic and imperiled fishes. the objectives of this study were to determine distribution and definitive hosts of the asian fish tapeworm within the rio grande drainage and to quantify occurrences and abundances. in total, 1,992 fish spanning 11 families were collected and examined for asian fish tapeworms in the rio grande and the pecos and ... | 2010 | 21192548 |
| first record of bothriocephalus acheilognathi in the rio grande with comparative analysis of its2 and v4-18s rrna gene sequences. | bothriocephalus acheilognathi is an introduced tapeworm in north america often reported as a serious ecological threat to native fishes. in this paper, we report the first record of b. acheilognathi in the big bend region of the rio grande in texas (known as the río bravo del norte in mexico). identification of b. acheilognathi was confirmed by morphologic and genetic techniques (sequences of its2 and v4-18s rrna genes). its prevalence was 27% and its intensity ranged from 1 to 5 individuals in ... | 2007 | 18201046 |
| clestobothrium gibsoni n. sp. (cestoda: bothriocephalidae) from the bullseye grenadier bathygadus macrops goode & bean (macrouridae) in the gulf of mexico. | clestobothrium gibsoni n. sp. is described from the intestine of the bullseye grenadier bathygadus macrops (macrouridae) collected in the northeastern gulf of mexico. the new species can be distinguished from both c. crassiceps (rudolphi, 1819), the type-species of the genus, and c. neglectum (lönnberg, 1893), the second species in the genus, by its unique ovary, which is transversely elongate and tapered on both ends rather than being u-or h-shaped, and by having more testes (60-65 vs 40-50 and ... | 2005 | 15791401 |
