Trichomonas Flashcards
What are the names and main feature of the 4 Genuses of Trichomonas:
- Ditrichomonas = 2 anterior flagella
- Tritrichomonas = 3 anterior flagella
- (Tetra)trichomonas = 4 anterior flagella
- Pentatrichomonas = 5 anterior flagella
How do Trichomonas reproduce:
By Binary fission
What are the vectors for Trichomonas:
*They are transmitted mechanically by vector and are highly host specific, as they have a direct life cycle (one host)
