| ichthyophonus irregularis sp. nov. from the yellowtail flounder limanda ferruginea from the nova scotia shelf. | a previously described unusual form of the protistan parasite ichthyophonus, differing in morphological and developmental features from i. hoferi sensu plehn & mulsow, was recovered from yellowtail flounder limanda ferruginea storer from the brown's bank area of the nova scotia shelf. the nuclear gene encoding the rrna of the small ribosomal subunit was amplified from this unusual form of ichthyophonus using the polymerase chain reaction, sequenced and aligned with other eukaryote small subunit ... | 2000 | 10907136 |
| are ichthyosporea animals or fungi? bayesian phylogenetic analysis of elongation factor 1alpha of ichthyophonus irregularis. | ichthyosporea is a recently recognized group of morphologically simple eukaryotes, many of which cause disease in aquatic organisms. ribosomal rna sequence analyses place ichthyosporea near the divergence of the animal and fungal lineages, but do not allow resolution of its exact phylogenetic position. some of the best evidence for a specific grouping of animals and fungi (opisthokonta) has come from elongation factor 1alpha, not only phylogenetic analysis of sequences but also the presence or a ... | 2003 | 14615193 |
