Tritrichomonas foetus

  • Venereally transmitted
  • Cattle protozoa
  • Lives in the uterus and preputial cavity of bulls
  • Occurs worldwide
  • Fatal diseases in wild birds caused by T. gallinae
    • Necrotic, yellow nodules in the crop and 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


  • Occurs in the digestive tract of other species
    • Usually as commensal organisms
  • T. gallinae is pathogenic in pigeons
