TABLE 1.
Small intestine tumor multiplicity and prevalence of cecal and colon tumors in B6-Min, BALB-Min, BALB-RagMin, and H. hepaticus-infected BALB-RagMin micea
| Strain | No. of mice | Age range (mo) | SI tumor multiplicity mean ± SD (median) | % of mice with tumors (no. with tumors/total no.)

|
|---|---|---|---|---|---|
| Cecal | Colon | ||||
| B6-Min | 18 | 4-6 | 101.1 ± 58.5 (76.5)A | 66.7 (12/18)D | 77.8 (14/18)E |
| BALB-Min | 17 | 5-15 | 27.4 ± 13.9 (24.0)A,B,C | 5.9 (1/17)D | 5.9 (1/17)E |
| BALB-RagMin | 60 | 4-9 | 46.0 ± 29.0 (43.0)B | 0 (0/60) | 1.7 (1/60)F |
| BALB-RagMin (with H. hepaticus infection) | 34 | 4-8 | 38.5 ± 16.6 (37.5)C | 5.9 (2/34) | 23.5 (8/34)F |

The Mann-Whitney test was used to determine if differences in small intestine (SI) tumor multiplicity were significant. Fisher's exact test was used to determine if differences in cecal and colon tumor prevalence were significant. Values with the same superscript are significantly different from each other. A, E, and F, P ≤ 0.001; B and D, P < 0.01; C, P < 0.05.
