چکیده
A Gram-stain-negative, aerobic, non-motile, rod-shaped bacterial strain, designated YSS-7(T), was isolated from a sea squirt (Halocynthia roretzi) collected from the South Sea of South Korea. Strain YSS-7(T) grew optimally at 25 °C, at pH 7.0-8.0 and in the presence of 2.0% (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain YSS-7(T) clustered with the type strains of Pelagicola litoralis, Planktotalea frisia, Pacificibacter maritimus and Roseovarius marinus. Strain YSS-7(T) exhibited the highest 16S rRNA gene sequence similarity (97.7%) to the type strain of Pelagicola litoralis and sequence similarity of more than 96.0% to the type strains of some other species. Strain YSS-7(T) contained Q-10 as the predominant ubiquinone and C18:1ω7c and 11-methyl C18:1ω7c as the major fatty acids. The major polar lipids of strain YSS-7(T) were phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid. The fatty acid and polar lipid profiles of strain YSS-7(T) were different from those of the type strains of phylogenetically related species. The DNA G+C content of strain YSS-7(T) was 55.5 mol%. Other phenotypic properties demonstrated that strain YSS-7(T) is distinguished from phylogenetically related species. On the basis of the data presented, strain YSS-7(T) is considered to represent a novel genus and species, for which the name Pseudopelagicola gijangensis gen. nov., sp. nov. is proposed. The type strain of Pseudopelagicola gijangensis is YSS-7(T) ( = KCTC 42049(T) = CECT 8540(T)).

The eugregarines are a group of apicomplexan parasites that mostly infect the intestines of invertebrates. The high level of morphological variation found within and among species of eugregarines makes it difficult to find consistent and reliable traits that unite even closely related lineages. Based mostly on traits observed with light microscopy, the majority of described eugregarines from ma...
