==Coccidia of Pigs==
==Coccidia of Pigs==
+
*Many species of ''Eimeria'' and ''Isospora''
+
+
*Only ''Isospora suis'' is of clinical pathogenic importance
+
+
*Causes sporadic, serious and sometimes fatal disease in unweaned piglets
+
**Causes profuse [[Intestine Diarrhoea - Pathology|diarrhoea]]
+
+
*Very short 1 week prepatent period
+
+
*[[Intestine Diarrhoea - Pathology|Diarrhoea]] starts before oocysts are shed in faeces
+
**Ante-mortem diagnosis is difficult
+
+
*Death usually occurs after parasites have left the host
+
**Post-mortem diagnosis difficult
+
**''Isospora'' infections are '''self-limiting'''
==Coccidia of Dogs==
==Coccidia of Dogs==
+
*2 common and 2 less common ''Isospora'' species
+
+
*Occasionally can cause disease
+
+
*Little pathogenicity
+
+
*Even if faecal oocyst count is high, other causes of [[Intestine Diarrhoea - Pathology|diarrhoea]] should be looked for

+
*2 common ''Isospora'' species with little clinical significance
+
+
*Oocysts in faeces have to be distinguised from those of ''Toxoplasma'' (smaller) and ''Sarcocytis'' (sporulated or naked sporocyts in faeces)
