Incidence of spirochaetal infections in cases of intestinal disorder in chickens.
The incidence of intestinal spirochaetes was determined using direct fluorescent antibody microscopy on faecal and mucosal samples from chickens. Of 134 flocks with intestinal disorders 27.6% were found to be positive, but only 4.4% (of 45 flocks) were positive where signs of enteritis were absent. Flocks housed in cages or with access to litter were equally affected. No evidence was found for pigs as an aetiological factor.
