Trichomonas gallinae is a cosmopolitan parasite of birds including finches, pigeons, doves, turkeys, chickens, parrots, and raptors (hawks, golden eagle, etc.). The condition in birds of prey is called frounce . [ 1 ]
Trichomonas vaginalis, being the species that causes the most complications in humans, is the only fully sequenced Trichomonas species. Through whole-genome shotgun sequencing, the Trichomonas vaginalis genome is estimated to be around 160 Mb long, divided into six chromosomes. However, at least 65% of its genome was found to be redundant.
Trichomoniasis (trich) is an infectious disease caused by the parasite Trichomonas vaginalis. [2] About 70% of affected people do not have symptoms when infected. [ 2 ] When symptoms occur, they typically begin 5 to 28 days after exposure. [ 1 ]
Histomonas meleagridis reproduces by binary fission.The free trophozoites are very delicate and can survive only for a few hours in the external environment. However, when they are transmitted between flocks in the eggs of Heterakis gallinarum, a cecal nematode, which in turn can be transmitted by earthworms that ingested the nematode eggs, they gain entry into the nematode eggs.
Heterakis gallinarum is a nematode parasite that lives in the cecum of some galliform birds, particularly in ground feeders such as domestic chickens and turkeys. It causes infection that is mildly pathogenic .
Carcinogenic parasites are parasitic organisms that depend on other organisms (called hosts) for their survival, and cause cancer in such hosts.Three species of flukes are medically-proven carcinogenic parasites, namely the urinary blood fluke (Schistosoma haematobium), the Southeast Asian liver fluke (Opisthorchis viverrini) and the Chinese liver fluke (Clonorchis sinensis).
Trichomonas vaginalis from a vaginal swab. This is a heavy infection; there were probably thousands of trichomonads in the vagina. Alfred Francois Donné (1801–1878) was the first to describe a procedure to diagnose trichomoniasis through "the microscopic observation of motile protozoa in vaginal or cervical secretions" in 1836.
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Protozoan parasite trichomonas vaginalis serve as the natural host. [1]
