Coccidiosis in Geese
Coccidiosis in Geese caused by Eimeria truncata and Eimeria anseris species. It is 100% fatal disease in geese.
Etiology
- E. truncata: causes renal coccidiosis.
- E. anseris: causes intestinal coccidiosis.
- Mortality: 100%.
Clinical manifestation
- Haemorrhagic enteritis.
- Nephritis, marked emaciation and muscular incoordination.
Lesion
- Enlargement of kidney.
- Pin head sized grayish white foci or haemorrhagic petechia with accumulation of urates on kidney.
Diagnosis
- History of the flock.
- Finding various types of lesions and their locations by P.M. examination.
- Faecal examination for the presence of oocysts is of little significance in severe out breaks and clinical cases, as the mortality starts before the discharge of oocysts.
- Examination of gut scrapings for the presence of schizonts and unsporulated oocysts.
- Study of sporulated oocysts by allowing sporulation of oocysts after mixing faeces with several volumes of 2.5 % Potassium dichromate solution for 1 day to 2 weeks.
