“…These ciliates live on a wide range of limnetic and marine invertebrates and vertebrates. A few of them have been implicated in sometimes fatal fish diseases, causing much economic loss (Van As & Viljoen 1984; Van As & Basson 1987; Xu & Song 1998; Xu et al. 2000).…”

Evaluating molecular support for and against the monophyly of the Peritrichia and phylogenetic relationships within the Mobilida (Ciliophora, Oligohymenophorea). -Zoologica Scripta, 42, 213-226. An ongoing debate in ciliate molecular phylogenetic analyses is whether the Peritrichiacomposed of the Sessilida and the Mobilida -are monophyletic. To further investigate this group, here we increase taxon sampling with four further mobilids: Trichodinella sp., Trichodina pectenis, Urceolaria serpularum and Urceolaria korschelti. Results show that support for and against monophyly of the peritrichs depends on different methods of alignment, and different methods of masking ambiguously aligned nucleotide positions. Results from constrained analyses also are dependent on different alignment and masking methods. We propose that there is no well-supported SSU-rDNA evidence supporting for and against the removal of the mobilids from the peritrichs. Within the Mobilida, we find that Trichodinella nest within Trichodina, Urceolaria branch basally, and Trichodina are non-monophyletic, and suggest that Leiotrocha be formally transferred into Urceolaria. In addition, the data support that Urceolaria-like denticles and Urceolaria-⁄ Trichodina-like adoral ciliary spiral are plesiomorphic conditions within the mobilids.

“…Occasionally the ventral surfaces of males and females were heavily infested by sessile peritrichians, identified as Epistylis nympharum (Engelmann, 1862) (Van As & Viljoen, 1984). According to Sutherland & Wittrock (1986) this is probably frequent amongst copepods.…”

Epistyliasis has been characterized as an emergent disease which has a great impact on fish farms, especially on Oreochromis niloticus production systems. Although epidemiological important, information about the dispersion of these parasites and their mechanical vectors is scarce. The present study reported the cooccurrence of Epistylis sp. as an epibiont of Dolops carvalhoi, a parasitic crustacean of cultivated/wild specimens (from accidental release) of O. niloticus from a cage fish farm area in the Ilha Solteira Reservoir, Grande River, SP, Brazil. The co-occurrence of Epistylis sp. and D. carvalhoi, and their epibiont relationship registered in this study suppose that the Epistylis may use the crustaceans for dispersion and as mechanical vectors for the dissemination of diseases in wild and cultivated hosts. Moreover, exchange of parasites between wild and cultivated hosts is possible, considering both organisms (protozoan and argulid). Furthermore, the results of the present study demonstrate the need to monitor the areas adjacent to cage fish farms as a preventive measure for the dispersion of pathogens. This is the first report of epibiosis between Epistylis sp. and argulid parasites of cultivated and wild O. niloticus, contributing to knowledge about host-parasite specificity, geographical distribution, dispersion of etiological agents and epidemiology in aquaculture.
