29
**Coccidiosis in rabbit** Intestinal lumen Gamonts= dark blue Unnucleated RBC = red
30
**Unnucleated RBC** (in case of mammals)
31
**Mammal Coccidiosis** **Mammal** --\> Unnucleated RBC above Microgametes (left) Macrogamonts (right)
32
**Coccidiosis in rabbit** pinhead size white nodules in ileum of the rabbit—\> **E. magna** catarrhal and haemorrhagic enteritis thickening of mucosa in small intestines
33
**Coccidiosis in rabbit** large pale intestines -infection- like Brain Gyri
34
**Coccidiosis in rabbit** large pale intestines -infection- like Brain Gyri

**Coccidiosis in rabbit** intestinal coccidiosis of rabbits inside the caecum —\> **E. flavescens**- catarrhal and haemorrhagic enteritis thickening of mucosa in large intestine
36
**Coccidiosis in rabbit** large pale intestines -infection- like Brain Gyri
37
**Left:** Eimeria **Right:** Isospora **Isospora:** - No cap - No operculum - No residual body - 2 Sporocyst (E: 4) - 4 Sporozoites (E: 2)
38
**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
**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
**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)
