The parasite is frequently encountered in periodontal infections affecting more than 50 of the population in some areas but it is usually considered. Trichomonas gallinae are small 5 to 20 µm size oval to pea-shaped flagellates with four free anteriorly placed flagella axostyle protruding from the posterior end and an undulating membrane. However due to the lack of a cystic wall surrounding the organism.

Molecular and Biochemical Parasitology 44197-108. Circular DNA and. The natural hosts are human beings where the parasite lives as a colourless pyriform flagellate measuring usually 15 to 18 ц in length and 5 to 15 ц in breadth.

Trichomonas vaginalis is the parasitic protozoan residing in human urogenital tract causing trichomoniasis which is the leading non-viral sexually transmitted disease.

It has cosmopolitan distribution throughout the globe and affects both men and women. The parasite does not appear to have a cyst form and does not survive well in the external environment. Lifecycle of the parasite has been traditionally described as consisting of motile and symptom-causing trophozoites.

T vaginalis is transmitted among humans the only known host. Pseudocysts also appear to undergo asexual binary fission within the cyst. RIS PDF - 41017 KB Corporate Authors.

Morphology Habitat Nutrition and Life Cycle. It lacks a cyst form but many studies have noted a unique form in which Trichomonas appears ovoidal rather than its typical pear-shaped form. They exist only in trophozoite phase and there is no cystic phase.
