Table 1. Histopathological results of H. felis-infected Balb/c Plcg2^Ali5/+ and WT mice.

Group	Time post-infection [months]	Genotype	Number of mice		Normal findings	Lymphoid aggregates	MALT lymphoma
			Enrolledd	Diede
1a	6	Plcg2 Ali5/+	11	1	40% (4/10)	60% (6/10)	0%
		WT	11	0	46% (5/11)	54% (6/11)	0%

BALB/c Plcg2^Ali5/+ and WT mice were orally infected with H. felis on day 1, 3 and 5 and followed-up for 6, 12 and 16 months. Normal finding indicates healthy gastric mucosa.

Statistical analysis was done with Fisher´s exact test for

^a, (comparison of genotypes for MALT lymphoma development with lymphoid aggregates) Plcg2^Ali5/+ versus WT mice p = 1

^b, (comparison of genotypes for MALT lymphoma development with lymphoid aggregates) Plcg2^Ali5/+ versus WT mice p = 0.1431

^c (comparison of genotypes for MALT lymphoma development with lymphoid aggregates) Plcg2^Ali5/+ versus WT mice p = 0.0142

^d Number of mice enrolled at the beginning of the study.

^e Number of mice that died/killed during the study (within 6 months after infection).
