Correlation between megaloileitis and antibodies to Bacillus piliformis in laboratory rat colonies.
Rat colonies in which antibodies to Bacillus piliformis were detected in animals examined at the age of 8 to 15 weeks were compared with rat colonies where no such antibodies were present. The seropositive colonies had a low incidence of megaloileitis in 5-week-old rats of Sprague-Dawley stock and some few inbred strains. In seronegative colonies, no megaloileitis was detected. In rats with megaloileitis, significantly high titers to B. piliformis were noted and the agents could be identified in the ileal mucosa by immunofluorescence technique.
