a
The results of biopsies taken from the pyloric antrum, body, and cardia or fundus were pooled and are presented as positive (+) or negative (−). Biopsies were obtained by endoscopy 3.5 and 8.0 months after infection with H. felis. All cats were negative by all tests prior to inclusion in the study. MS, modified Steiner stain; Ure, urease production.
