Necrotic Enteritis

Necrotic Enteritis

Bloody diarrhoea is typical for Necrotic Enteritis.

Diagnosis

Bloody diarrhoea in the first few days of life is typical of necrotic enteritis. The diagnosis can be done by necropsy or with faecal samples. After confirmation by bacteriological culture, the toxins can be determined using PCR.

Band-like stripes in intestines – a clear lesion of NE.

Pathology

At necropsy, gross lesions include bloody intestinal contents and gas production. Histopathological lesions of necrosis of the intestinal lining (mucosa), destruction of the endothelial cells, and detachment of the basement membrane can be observed in some cases. In cases of chronic NE the intestinal mucosa is covered with thick, necrotic membranes, and this gives the intestines an appearance of band-like stripes.
