Abstract

AbstractThe influence of anaerobic protozoanBlastocystison human gut health is not well understood. WhileBlastocystisspecies frequently inhabit the gut, their clinical importance and ecological function remain ambiguous. A study onBlastocystiswas carried out enrolling a total of 203 participants including T2DM patients and non-diabetic individuals to evaluate the prevalence ofBlastocystisand its association in gut microbiota.Blastocystissubtypes were identified by PCR and faecal microbiome was accessed by targeting V4 region of the bacterial 16S ribosomal gene. The prevalence ofBlastocystisin T2DM was 25.49% and 17.82% in non-diabetic individuals with the most prevalent subtype on total population was ST3, followed by ST1 and ST2. The composition of gut microbiota was significantly different betweenBlastocystis-positive andBlastocystis-negative individuals.Blastocystiscarriage was positively associated with higher alpha diversity in T2DM patients and non-diabetic individuals. Interestingly, at the phylum level, the T2DM group had an obvious increase of Bacteroidetes and a marked increase of Actinobacteria with the present ofBlastocystis. The findings suggested that the presence ofBlastocystiswas linked to increased diversity and richness in the gut bacterial composition, signifying at a potentially beneficial association betweenBlastocystisand the gut microbiota.Author SummaryType 2 Diabetes Mellitus Patients (T2DM), a prevalent global disease, affects a significant portion of the population across the world. Thus, there is need to better understanding onBlastocystisinfection among T2DM that could lead to the alteration toward gut health. We evaluated the association betweenBlastocystisand gut microbiota, where involving two groups; T2DM patients and non-Diabetic individuals. The research revealed a higherBlastocystisin T2DM patients compared to non-diabetic individuals, emphasizing on assumption toward its pathogenicity. However, amplicon-based sequencing of 16S rRNA genes indicates thatBlastocystiscarriers exhibit increased gut microbiota diversity. Our result suggested that,Blastocystishighlighted its potential role as a component of a balanced microbiota. Notably, optimal alteration in Actinobacteria and Bacteroidetes may contribute to the several gut health. Hence, the study could prompt for further exploration regarding ofBlastocystissubtypes and gut microbiota specifically in T2DM to propose for more precise assessment ofBlastocystisand gut microbial diversity.
