==''Tritrichomonas foetus''==
*Venereally transmitted
*Cattle protozoa
*Lives in the [[Female Reproductive Tract -The Uterus - Anatomy & Physiology|uterus]] and preputial cavity of bulls
*Occurs worldwide
*Related species cause [[Intestine Diarrhoea - Pathology|diarrhoea]] in cats
*Fatal diseases in wild birds caused by ''T. gallinae''
**Necrotic, yellow nodules in the [[Crop- Anatomy and Physiology|crop]] and [[Oesophagus - Anatomy & Physiology|oesophagus]]
**Infection is usually fatal
**Turkeys and chickens may also become infected
*Non-pathogenic species affect guinea-pigs
'''Recognition'''
*10-25μm long
*Pear-shaped
*3 anterior flagella and 1 posterior flagellum forming an undulating membrane
*Body is supported by an axostyle
**Hyaline rod
**Projects posteriorly
*Single nucleus present
'''Life Cycle'''
*Simple
*Reproduce by binary fission
*Transmission via direct contact
'''Pathogenesis'''
*No clinical signs in the bull once established
**Inhabits the preputial cavity
**Once infected, bulls remain so permanently
*Infertility and abortion in the cow
**Inhabits the [[Female Reproductive Tract -The Uterus - Anatomy & Physiology|uterus]] and [[Female Reproductive Tract -The Vagina/Vestibule - Anatomy & Physiology|vagina]]
*Prevalence has dramatically decreased in cattle since the introduction of artificial insemination
*Occurs in the digestive tract of other species
**Usually as commensal organisms
*''T. gallinae'' is pathogenic in pigeons
**Inhabits the [[Crop- Anatomy and Physiology|crop]]
'''Diagnosis'''
*Microscopic examination of [[Female Reproductive Tract -The Vagina/Vestibule - Anatomy & Physiology|vaginal]] or preputial washings[[Category:Protozoa]]
