| dactylogyrus olfactorius n. sp. (monogenea, dactylogyridae) from the olfactory chamber of the fathead minnow, pimephales promelas rafinesque (cyprinidae). | dactylogyrus olfactorius n. sp. (monogenea) is described from the olfactory chamber of the fathead minnow pimephales promelas rafinesque in alberta, canada. the new species resembles dactylogyrus bychowskyi mizelle, 1937, d. bifurcatus mizelle, 1937 and d. simplexus mizelle, 1937, all parasites of pimephales spp. in north america, in overall size and shape of the anchors and hooks, and in having a male copulatory complex with a tapered tubular penis and bifurcate accessory piece. diagnostically, ... | 2016 | 27307170 |
| parasites and a host's sense of smell: reduced chemosensory performance of fathead minnows (pimephales promelas) infected with a monogenean parasite. | parasites residing within the central nervous system of their hosts have the potential to reduce various components of host performance, but such effects are rarely evaluated. we assessed the olfactory acuity of fathead minnows (pimephales promelas) infected experimentally with the monogenean dactylogyrus olfactorius, the adults of which live within the host's olfactory chambers. olfactory acuity was compared between infected and uninfected hosts by assessing electro-olfactography (eog) neural r ... | 2017 | 28127759 |
