pinhead size white nodules in ileum of the rabbit—> E. magna

catarrhal and haemorrhagic enteritis

thickening of mucosa in small intestines

33
Q
A

Coccidiosis in rabbit

large pale intestines -infection-

like Brain Gyri

34
Q
A

Coccidiosis in rabbit

large pale intestines -infection-

intestinal coccidiosis of rabbits inside the caecum —> E. flavescens-

catarrhal and haemorrhagic enteritis

thickening of mucosa in large intestine

36
Q

large pale intestines -infection-

like Brain Gyri

37
Q
A

Left: Eimeria

Right: Isospora

Isospora:

  • No cap
  • No operculum
  • No residual body
  • 2 Sporocyst (E: 4)
  • 4 Sporozoites (E: 2)
38
Q
A

Isospora canis

Oocyst with 2 sporocysts inside but very small

  • isospora does not have a Micropyle cap and a polar granule

Sporozoites - carnivores and pig have isospora

MIDTERM SOS

39
Q
A

Isospora canis

Oocyst with 2 sporocysts inside but very small

  • isospora does not have a Micropyle cap and a polar granule

Sporozoites - carnivores and pig have isospora

MIDTERM SOS

40
Q
A

Isospora general structure

Oocyst with 2 sporocysts inside but very small

  • isospora does not have a Micropyle cap and a polar granule

Sporozoites - carnivores and pig have isospora

41
Q
A

Isospora suis

Right =sporulated oocyst

Left = unsporulated oocyst

  • isospora does not have a Micropyle cap and a polar granule-

Best way of detecting with kynion staining,

and the flotation test (salt, sugar, zink sulfate)

42
