Tritrichomonas foetus
''Tritrichomonas foetus'' is a single celled flagellated protozoan parasite that is known to be a pathogen of the bovine reproductive tract as well as the intestinal tract of cats. In cattle, the organism is transmitted to the female vagina and uterus from the foreskin of the bull where the parasite is known to reside. It causes infertility, and, at times, has caused spontaneous abortions in the first trimester. Cases of infection in cattle have declined due to the use of artificial insemination. In the last ten years, there have been reports of ''Tritrichomonas foetus'' in the feces of young cats that have diarrhea and live in households with multiple cats.
==Description==
''Tritrichomonas foetus'' in the genus ''Tritrichomonas'' within the order Trichomonadida in the Kingdom Protoctista. The parasite is 5-25 µm in size and is spindle shaped with four flagella which are whiplike projections and an undulating or wavy membrane. Their movement is jerky and in a forward direction, and they also do "barrel rolls". The organisms look like small tadpoles with small tails when viewed microscopically. The parasite interacts with bacteria that normally reside in the intestinal tract by adhering to the intestinal epithelium of the host.
