The genome sequence and gene models of Trichomonas vaginalis were not determined by the Joint Genome Institute (JGI), but were downloaded from NCBI on May 29, 2018. In order to allow comparative analyses with other genomes sequenced by the JGI, a copy of this genome is incorporated into the JGI Genome Portal. JGI tools were used to automatically annotate predicted proteins. Please note that this copy of the genome is not maintained by NCBI and is therefore not automatically updated.

Trichomonas vaginalis

Trichomonas vaginalis is a flagellated protozoan parasite that is the causal agent of human trichomoniasis. This infection is typically transmitted by sexual intercourse and accounts for approximately 170 million cases per year worldwide, making it one of the most prevalent non-viral sexually transmitted diseases in the world. This is an extracellular parasite that adheres to the epithelium of the urogenital tract of both men and women and is responsible for urethritis, prostatitis or vaginitis, respectively. In North America alone, T. vaginalis is responsible for approximately 5 million cases of vaginitis annually. Furthermore, this organism has been associated with increased risk of HIV infection. T. vaginalis appears to exist only as a trophozoite which divides by binary fission. Because T. vaginalis is anaerobic, it does not contain mitochondria in its cytoplasm. Instead, it possesses specialized granule-like organelles called the hydrogenosomes which are involved in the parasite's carbohydrate metabolism. A new predicted function for the hydrogenosomes recently revealed by the genome sequence of T. vaginalis is involvement in aminoacid metabolism.
