Incidental finding of Myxobolus spores (protozoa: myxozoa) in stool samples from patients with gastrointestinal symptoms.
Myxozoan spores were detected in fecal samples from three patients presenting with abdominal pain and/or diarrhea. The spores were identical to those of Myxobolus plectroplites, a previously described pathogen from the freshwater fish Plectroplites ambiguus. All patients had recently eaten fish caught from local waters, and frozen fillets of such fish were found to be infected with M. plectropl...
متن کاملSupplemental description of Myxobolus squamalis (Myxozoa).
Myxobolus squamalis is a myxozoan skin parasite first reported from rainbow trout (Oncorhynchus mykiss). Identification of the parasite based on myxospore morphology is unreliable because M. squamalis is similar to several other myxobolids that share host species and geographic ranges. The only ssrRNA gene sequence available for M. squamalis is from Chinook salmon, Oncorhynchus tschawytscha, bu...
متن کاملReport of spores of Henneguya salminicola (Myxozoa) in human stool specimens: possible source of confusion with human spermatozoa.
The spores of Henneguya salminicola, a common tissue parasite of salmonid fishes in the northern hemisphere, were observed in stool specimens from two different patients with diarrhea. The spores' superficial resemblance to human spermatozoa resulted, in one instance, in an incorrect report, leading to suspicion of sexual abuse. H. salminicola spores and human spermatozoa can be differentiated ...
متن کاملGenomic insights into the evolutionary origin of Myxozoa within Cnidaria.
The Myxozoa comprise over 2,000 species of microscopic obligate parasites that use both invertebrate and vertebrate hosts as part of their life cycle. Although the evolutionary origin of myxozoans has been elusive, a close relationship with cnidarians, a group that includes corals, sea anemones, jellyfish, and hydroids, is supported by some phylogenetic studies and the observation that the dist...
متن کاملAgent of Whirling Disease Meets Orphan Worm: Phylogenomic Analyses Firmly Place Myxozoa in Cnidaria
Myxozoa are microscopic obligate endoparasites with complex live cycles. Representatives are Myxobolus cerebralis, the causative agent of whirling disease in salmonids, and the enigmatic "orphan worm" Buddenbrockia plumatellae parasitizing in Bryozoa. Originally, Myxozoa were classified as protists, but later several metazoan characteristics were reported. However, their phylogenetic relationsh...
