Trichomonas/ Tritrichomonas Flashcards
How are they grouped?
According to the number of anterior flagellae
(4) vaginalis and gallinae
(3) foetus(suis) and equi
foetus: Diagnosis
Microscopic exam of preputial washing, semen or vaginal discharge– GIEMSA
Caruncles of aborted fetus- GIEMSA
foetus: Position of parasite
(epicellular of fetus?)
foetus: Development
Always direct- host to host infection by veneral contact
ARE UNABLE TO FORM CYSTS
foetus: Morphology of trophozoites
pear-shaped
1 flagella undulating backwards
3 flagella forwards
Can also be pleomorphic
What is another name for trichomonas gallinae?
Canker
Mainly in squabs
gallinae: sample and method
Smear from crop
Foetus: clicial signs
Bulls: inapparent, rarely inflamm of mm preputium and urethral discharge
Cows/heifers: vestibulitis, vaginitis, vaginal discharge, early abortion, pyometra
foetus: patho signs
grey/ yellow papules on the chorion
gallinae: diagnosis
exam of the scrapings of the lesion- look for the jerking movement
gallinae: Position of parasites
EC lumen dwelling flagellates
gallinae: Host and vector
infection of young pigeons via the crop
Kissing, contaminated drinking water
gallinae: Life cycle/ development
Direct
Multiplication with binary fission epicellularly on mucosal surfaces
gallinae: clinical signs
squabs: depression, weakness, anorexia
young: dyspnoea
Chicken, turkey: drowsiness
Ulcerative dermatitis in mouth
gallinae: patho signs:
Mucosal form:Diphtheric membrane in mouth, esophagus and pharynx, pseudomembrane
Hepatic form: necrotic nodules
Generalized: necrotic in the resp organs
