Number of Positive Cells per Square Millimeter after Immunostaining with Various Antibodies in the Villous Lamina Propria of the Duodenum

The average of Lambda positive cells was 1,594 per mm2 and of Kappa positive cells 322 per mm2; thus the λ/κ ratio is 5. The average of IgA positive cells was 1,335 per mm2 and of IgM positive cells 202 per mm2, thus the IgA/IgM ratio is 6.6. *P<0.05, Dunnett multiple comparisons test. ##P<0.01, Dunnett multiple comparisons test. #P<0.05, Dunnett multiple comparisons test. #P-value as compared with dogs who received only Salmonella. **P-value as compared with dogs from control groups.
