Identification of Multiple Blastocystis Subtypes in Domestic Animals From Colombia Using Amplicon-Based Next Generation Sequencing.
Abstract: is frequently reported in fecal samples from animals and humans worldwide, and a variety of subtypes (STs) have been observed in wild and domestic animals. In Colombia, few studies have focused on the transmission dynamics and epidemiological importance of in animals. In this study, we characterized the frequency and subtypes of in fecal samples of domestic animals including pigs, minipigs, cows, dogs, horses, goats, sheep, and llama from three departments of Colombia. Of the 118 fecal samples included in this study 81.4% ( = 96) were positive for using a PCR that amplifies a fragment of the small subunit ribosomal RNA ( rRNA) gene. PCR positive samples were sequenced by next generation amplicon sequencing (NGS) to determine subtypes. Eleven subtypes were detected, ten previously reported, ST5 (50.7%), ST10 (47.8%), ST25 (34.3%), ST26 (29.8%), ST21 (22.4%), ST23 (22.4%), ST1 (17.9%), ST14 (16.4%), ST24 (14.9%), ST3 (7.5%), and a novel subtype, named ST32 (3.0%). Mixed infection and/or intra -subtype variations were identified in most of the samples. Novel ST32 was observed in two samples from a goat and a cow. To support novel subtype designation, a MinION based sequencing strategy was used to generate the full-length of the rRNA gene. Comparison of full-length nucleotide sequences with those from current valid subtypes supported the designation of ST32. This is the first study in Colombia using NGS to molecularly characterize subtypes of in farm animals. A great diversity of subtypes was observed in domestic animals including subtypes previously identified in humans. Additionally, subtype overlap between the different hosts examined in this study were observed. These findings highlight the presence of subtypes with zoonotic potential in farm animals indicating that farm animals could play a role in transmission to humans.

This study centers around identifying different subtypes of Blastocystis, a group of single-celled organisms, in domestic animals based in Colombia using an advanced genetic sequencing technique.
Overview of the Study
- In this research, the scientists examined fecal samples from a variety of domestic animals in Colombia—pigs, minipigs, cows, dogs, horses, goats, sheep, and llama.
- The purpose was to determine the presence and types (subtypes) of Blastocystis, which are commonly found in animals and humans, and have various subtypes.
- Out of 118 fecal samples, 81.4% (or 96 samples) tested positive for Blastocystis. This was done using a polymerase chain reaction (PCR) technique that amplifies a part of the small subunit ribosomal RNA (rRNA) gene of the Blastocystis.
Amplicon-Based Next Generation Sequencing (NGS)
- The researchers used next generation amplicon sequencing (NGS), an advanced genetic sequencing technique, on the PCR positive samples to identify the subtypes of Blastocystis present.
- NGS is a high-throughput methodology that allows many different genetic sequences to be read simultaneously, making it a faster and more efficient way of sequencing genomes.
Findings and Implications
- The scientists were able to identify eleven subtypes of Blastocystis, ten of which were previously reported, along with a new subtype named ST32.
- The most common subtypes found were ST5 (50.7%) and ST10 (47.8%), followed by ST25 (34.3%) and ST26 (29.8%).
- The new subtype, ST32, was observed in a goat and a cow. The presence of this new subtype was confirmed by generating the full-length of the Blastocystis rRNA gene through a sequencing strategy.
- The study reveals a large diversity of Blastocystis subtypes in domestic animals, including subtypes earlier found in humans. This finding emphasizes how domestic animals could contribute to transmitting Blastocystis to humans.
