Diversity of Protists I

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Summary

Intestinal trichomonads are rare in true bugs (Heteroptera). However, two of three identified flagellates were reptile-specific, suggesting potential transmission between these hosts.

Area of Science:

Microbiology and Parasitology
Entomology
Molecular Biology

Background:

Insect hindguts are known reservoirs for intestinal trichomonads, but their diversity remains largely unexplored.
True bugs (Heteroptera) represent a diverse insect order with limited investigation into their intestinal microbial communities.

Purpose of the Study:

To investigate the presence, abundance, and diversity of intestinal trichomonads in true bugs.
To identify trichomonad species found in true bugs and assess their host specificity.

Main Methods:

Microscopic examination of intestinal contents from over 780 true bug specimens across 28 families from China, Ghana, and Papua New Guinea.
Polymerase Chain Reaction (PCR) analysis using trichomonad-specific primers on over 120 samples.

Sequencing of SSU rDNA and ITS regions for isolate identification.

Main Results:

Trichomonads were found to be rare inhabitants of the true bug intestine.
Three isolates were identified: two belonging to the genus Simplicimonas and one Monocercomonas colubrorum.
Two of the three isolated flagellates were species typically found in reptiles.

Conclusions:

True bugs host a low diversity of intestinal trichomonads.
The presence of reptile-specific trichomonad species in true bugs suggests a potential for host-switching or transmission between reptiles and insects.
Further research is needed to elucidate the mechanisms and implications of trichomonad transmission between reptiles and true bugs.
