“…reported by Goggin and Barker (1993) and 98.0 % similar to that of P. marinus (Table 2). The nucleotide sequence of ITS region of the prezoosporangia of both Hiroshima and Kumamoto was identical or almost identical (99.9%) to those of P. atlanticus, P. olseni and non-specified 2 Perkinsus isolates (Goggin, 1994) , and 88.0% similar to that of P. marinus (Fig. 3) .…”

“…Thus, Perkinsus protozoan parasite of the short-necked clam in two prefectures of Japan may be P. atlanticus or closely related species. Goggin (1994) demonstrated a similarity between the sequences of ITS region of 4 isolates of Perkinsus species from Portugal (P. atlanticus) and Australia (P. olseni and 2 other isolates) and suggested that they belong to a single species. Azevedo (1989) proposed ( Goggin and Barker, 1993), and P. marinus (Fong et al, 1993) in short-necked clam Fig.…”

Tetrahymenosis, caused by about 10 Tetrahymena species, is an emerging problem inflicting a significant economic loss on the aquaculture industry worldwide. However, in the order Tetrahymenida, there are many unresolved evolutionary relationships among taxa. Here we report 21 new sequences, including SSU‐rRNA, ITS1‐5.8S‐ITS2 rRNA and LSU‐rRNA, genes of 10 facultative parasitic Tetrahymena associated with tetrahymenosis, and conduct phylogenetic analyses based on each individual gene and a three‐gene concatenated dataset. The main findings are: (1) All the parasitic and facultative parasitic species cluster in borealis group. (2) With the addition of new sequences, Tetrahymena is still divided into three groups, namely the “borealis group”, the “australis group,” and the “paravorax group.” (3) the cluster pattern of all the newly sequenced facultative parasitic Tetrahymena species shows that members of the “borealis” group may be more susceptible to parasitism. (4) phylogeny based on concatenated genes show that T. pyriformis, T. setosa, and T. leucophrys have close relationship.

In the class Colpodea, there are many unresolved evolutionary relationships among taxa. Here, we report 30 new sequences including SSU-rRNA, ITS1-5.8S-ITS2 rRNA, and the mitochondrial small subunit ribosomal RNA (mtSSU-rRNA) genes of five colpodeans, and conduct phylogenetic analyses based on each individual gene and a two-gene concatenated dataset. For the first time, multi-genes were used to analyze phylogenetic relationships in the class Colpodea. The main findings are: (1) SSU-rRNA, ITS1-5.8S-ITS2 rRNA, and mtSSU-rRNA gene sequences of C. reniformis and C. grandis are provided for the first time, and these two species group into the clade including C. inflata, C. lucida, C. cucullus, and C. henneguyi; (2) clustering pattern and morphological similarity indicate that Bresslauides discoideus has a close relation with Colpodidae spp.; (3) Emarginatophrya genus diagnosis is improved to be 'Hausmanniellidae with sharply shortened and isometric leftmost 1-4 ciliary rows' and Colpoda elliotti is transferred to Emarginatophrya; (4) the genus Colpoda is still non-monophyletic with the addition of 10 populations from five Colpoda species sequences, but there are only two Colpoda groups left based on the present work: Group I comprises C. inflata, C. lucida, C. cucullus, C. henneguyi, C. reniformis, and C. grandis, Group II comprises C. maupasi and C. ecaudata, and the presence of diagonal grooves and the way the vestibular opens might be the two key features that differentiates Colpoda species groups;(5) a close molecular relationship, and highly similar merotelokinetal mode, somatic ciliary pattern, and basic organization of the oral apparatus with P. steinii suggests Bromeliothrix metopoides should be temporarily assigned to Colpodidae.
