Summary
This study identified 164 proteins in Trichomonas vaginalis, revealing that carbohydrate metabolism proteins are most abundant. This research provides a key proteomic database for understanding this common sexually transmitted infection.
Area of Science:
- Microbiology
- Proteomics
- Parasitology
Background:
- Trichomoniasis, caused by Trichomonas vaginalis, is the world's most prevalent sexually transmitted infection.
- Trichomonas vaginalis possesses an exceptionally large genome with over 60,000 genes, and at least 4,000 genes are expressed in the trophozoite stage.
Purpose of the Study:
- To profile, identify, and characterize proteins expressed in the trophozoite stage of Trichomonas vaginalis.
- To establish a comprehensive proteomic database for T. vaginalis.
Main Methods:
- Utilized two-dimensional electrophoresis (2D-PAGE).
- Employed matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) for protein identification.
- Bioinformatically classified identified proteins based on known sequence or motif/domain homologies and biological functions.
Main Results:
- Successfully identified 164 distinct proteins from 247 protein spots in the T. vaginalis proteome.
- Proteins associated with carbohydrate metabolism were found to be the most abundant category.
- This represents the most extensive proteomic analysis of T. vaginalis conducted to date.
Conclusions:
- The study provides a valuable reference proteome for Trichomonas vaginalis.
- Understanding the T. vaginalis proteome, particularly carbohydrate metabolism proteins, can offer insights into parasite biology and potential therapeutic targets.
- This work lays the foundation for future comparative proteomic studies in parasitic protozoa.

01:18Trichomoniasis
Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
01:15Diversity 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...
01:33Proteomics
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...

01:29Bacterial Phylum Chlamydiae
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic of...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
