Trichostome ciliates are among the most conspicuous protists in the gastrointestinal tract of a large variety of vertebrates. However, little is still known about phylogeny of the trichostome/vertebrate symbiotic systems, evolutionary correlations between trichostome extrinsic traits, and character-dependent diversification of trichostomes. These issues were investigated here, using the relaxed molecular clock technique along with stochastic mapping of character evolution, and binary-state speciation and extinction models. Clock analyses revealed that trichostomes colonized the vertebrate gastrointestinal tract ∼135 Ma, that is, near the paleontological minimum for the split of therian mammals into marsupials and placentals. According to stochastic mapping, the last common ancestor of trichostomes most likely invaded the hindgut of a mammal. Although multiple shifts to fish/amphibian or avian hosts and to the foregut compartments took place during the trichostome phylogeny, only transition to the foregut was recognized as a key innovation responsible for the explosive radiation of ophryoscolecid trichostomes after the Cretaceous/Tertiary boundary, when ungulates began their diversification. Since crown radiations of main trichostome lineages follow those of their mammalian hosts and are in agreement with their historic dispersal routes, the present time-calibrated phylogeny might help to elucidate controversies in the geological and molecular timing of the split between marsupials and placental mammals.

“…The genus Balantidium has a large number of species that have been reported in the digestive tracts of a widely diverse range of invertebrate and vertebrate hosts such as molluscs, arthropods, fish, amphibians, reptiles, birds and mammals including humans (Biswas & Mukherjee, 1981;Bradbury, 1994aBradbury, , 1994bLi et al, 2008Li et al, , 2014. The protozoa reside in the intestine and are considered either commensal or endosymbionts in fish with no indications that those in fish infect humans; however, they are included in this review due to the need for a better overall understanding of the species present.…”

Background Fish is a great nutritious food and provides quality protein and a variety of vitamins and minerals. This contributes significantly to the economy and food security in Iran. However, there are safety concerns related to the presence of zoonotic parasites. Objectives The objective of this study is, therefore, to review fish‐borne zoonotic parasites in Iran. Methods Keywords such as fish‐borne, parasites, zoonotic, Iran, and some names of fish‐borne zoonotic parasites were searched in databases including PubMed, Science Direct, Elsevier, SID, Magiran, Irandoc, Google Scholar and the World Health Organization. Results The most common fish‐borne parasites with zoonotic potential identified in reports in the literature were the protozoa Balantidium spp., Myxobolus spp. and Sarcosystis sp.; the trematodes Heterophyes heterophyes and Clinostomum complanatum; the cestodes Ligula intestinalis and Diphyllobothrium latum; the nematodes Pseudoterranova sp., Anisakis spp., Contracaecum spp., Raphidascaris spp., Eustrongylides spp. and Capillaria sp.; and the acanthocephal Corynosoma spp. Conclusions The potential risk factors for the transmission of fish‐borne zoonotic parasites to humans are consumption of raw or undercooked infected fish, contact with contaminated water and contact with infected fish. There is a need for epidemiological surveillance of fish for parasites with zoonotic potential and of occurrence of infections in humans to better understand the public health significance and design prevention programs.

We obtained sequences of the small subunit ribosomal RNA (rRNA) for two new isolates of Balantidium from fishes, Balantidium polyvacuolum and Balantidium ctenopharingodoni. This is the first introduction of molecular data of Balantidium species from fish hosts in the phylogenetic analyses of the ciliate subclass Trichostomatia. Despite the fact that these species share morphological characteristics common to other species of Balantidium, the phylogenetic analysis of their sequences has shown that they are to be placed in a different branch closely related to the so-called Australian clade. Thus, our results indicate that the genus Balantidium is polyphyletic and possibly should be represented by two different genera; however, the analysis of more species from other poikilothermic hosts (amphibians, reptiles) should be made before a revised taxonomical proposal could be made.
