A histopathological survey of adult bovine terminal ilea.
A histopathological survey of 945 abattoir-derived adult bovine terminal ilea was conducted. All samples showed changes interpreted as chronic enteritis. Sixty-nine percent had glandular epithelium within submucosal Peyer's patches. Thirty-eight percent showed dense focal lymphoid aggregations within the mucosa and twenty-seven percent showed sub-mucosal abscessation and granulomata. Evidence of coccidial and nematode parasitism was common. Four percent had Johne;s disease.
