  10. Trichomonas suis

    "Swine nasal trichomonad"

    Slide made using saline or lactated ringers solution
    • Eimeria sp. of swine 
    • Oesophagostomum sp
  11. 3 Eimeria sp. shown
  12. Balantidium coli

    Swine

    Ciliated, found in cecum and colon causing "balantidosis". Mature form (trophozoite) which may cause dysentery in man and monkeys too.
  13. Balantidium coli

    Trophozoite form
    • Isospora bigemina (smaller)
    • Isospora ohioensis (bigger) 

    Coccidium of dogs, cats and foxes
  14. Isospora bigemina 

    Sporulated oocysts and sporocysts
    • F: Isospora felis
    • R: Isospora rivolta
    • T: Toxoplasma gondii 
    • C: Isospora cati (excreted sporulated)
    • A: Sporulated Isospora felis

    Face produced by nucleus, nucleoli and centroile rod
  17. Giardia

    Fresh cyst shows thin, smooth outer cyst wall
  18. Giardia 

    Distorted by hypertonic flotation solutions
  19. Entamoeba

    Trophozoites found in fresh feces, can cause severe dysentery
  20. Balantidium coli

    Usually seen in conjunction with Trichuris infection
  21. Coccidian oocysts float readily with little distortion
  22. Process of sporulation with coccidia occurs quickly in warm humid conditions and sporocysts can form in 24-48 hrs in feces
  23. Eimeria

    Pathogenicity in dogs is unknown
  24. Eimeria

    Development of sporocysts is proceeded by division of intact single cell of the oocyst into 4 cells

  26. Eimeria

    Ruminant
