| linking larvae and adults of apharyngostrigea cornu, hysteromorpha triloba and alaria mustelae (diplostomoidea: digenea) using molecular data. | abstract because the taxonomy of trematodes is based on adults, the larval stages of most digeneans cannot be identified to species based on morphology alone. molecular data provide a means of linking larval stages to known adults. we obtained sequences from the barcode region of cytochrome oxidase i (co1) from adult and larval parasites of fish, frogs, birds, and mammals across north america. sequences from adult apharyngostrigea cornu, hysteromorpha triloba, and alaria mustelae (diplostomoidea ... | 2011 | 21510747 |
| experimental transmission of vhsv genotype ivb by predation. | preliminary surveillance of wild baitfish during the 2006 viral hemorrhagic septicemia virus genotype ivb (vhsv ivb) outbreaks indicated emerald shiners notropis atherinoides and bluntnose minnow pimephales notatus were infected with high levels of vhsv without showing clinical signs of disease. the movement and use of baitfish was recognized as the most probable vector for the introduction of vhsv to inland waters, such as conesus lake and skaneateles lake in new york, budd lake in michigan, an ... | 2013 | 23998650 |
| taxonomy of myxobolus ridouti n. sp. and m. ridgwayi n. sp. (myxozoa) from pimephales notatus and semotilus atromaculatus (cypriniformes) in ontario. | myxobolus ridouti n. sp. and m. ridgwayi n. sp. are described, respectively, from pimephales notatus (rafinesque) and semotilus atromaculatus (mitchill) in algonquin park, ontario, canada. both are intracellular in striated muscles of the body flank. spores of m. ridouti n. sp. are subcircular (9.5-10.5 μm long by 9.4-10.9 μm wide); those of m. ridgwayi n. sp. are oval (10.0-12.1 μm long by 9.5-10.5 μm). both species have spores with a small, distinct swelling (1 μm) on the spore valve near the ... | 2009 | 19663535 |
