“…For example, data showing distinct patterns of infection between ST10 sequence variants was recently reported in a longitudinal study of dairy calves (Santin et al, 2023). Additionally, recent publications have reported ST10 in samples from humans living in Thailand and Vietnam (Jinatham et al, 2021;McCain et al, 2023;Nguyen et al, 2023). When sequences from humans from Thailand classified as ST10 were compared to full-length references for ST10 and ST42-ST44, we observed that both ST10 and ST42 represented best matches with over 99% sequence similarity.…”

The Blastocystis subtype ST10 has been recognized to contain a great deal of diversity at the sequence level, potentially indicating the presence of multiple new STs within the clade. However, the data needed to validate these new STs were not available. To help resolve this diversity, full‐length small subunit (SSU) rRNA gene reference sequences were generated using Oxford Nanopore MinION long‐read sequencing from 21 samples representing multiple domestic and wild hosts and geographic regions and covering the sequence diversity previously described using fragments of the SSU rRNA gene. Phylogenetic and pairwise distance analyses were used to compare full‐length sequences of the SSU rRNA gene generated in this study with all other valid STs of Blastocystis. We present data supporting the division of ST10/ST23 cluster into five subtypes, ST10, ST23, and three new subtypes with the proposed ST designations of ST42, ST43, and ST44. As the host range of Blastocystis continues to expand with new subtypes and new hosts being frequently identified, the reference sequences provided in this study will assist in accurate sequence classification and help to clarify the epidemiology of this common intestinal microeukaryote.

Blastocystis is a very common gastrointestinal protozoan globally distributed; it colonizes humans and non-humans, and in some communities, it reaches prevalences of up to 100%. Blastocystis is transmitted through the fecal-oral route, contaminated food and water, and close contact with animals. There are 34 known subtypes of Blastocystis, and subtypes 1 to 4 (ST1–ST4) are the most common in humans. It should be remembered that its pathogenicity is controversial since some studies have shown that Blastocystis is more prevalent in healthy individuals; who have greater diversity and richness of the intestinal microbiota; other studies suggest that Blastocystis infections occur in individuals with intestinal dysbiosis. In America and Africa, a high incidence of ST1 and ST2 is observed in rural areas. Recent data indicate that Blastocystis is linked with specific gut microbiota profiles and health indicators. Convincing information and tools that distinguish asymptomatic colonization from infection in children have yet to be demonstrated. Although this protozoan can cause disease under certain circumstances, but the attention of Blastocystis may change, as the frequency of Blastocystis subtypes in children may vary depending on the geographic area and local health conditions.
