Gastritis is a common finding in dogs with 35% of dogs investigated for chronic vomiting and 26% to 48% of asymptomatic dogs affected but the true prevalence in cats is yet to be determined. This study aimed to determine the prevalence of chronic gastritis in domestic and stray cats. The total rate was an estimated 66.6%. Thorough histopathological studies revealed no significant association between occurrence of chronic gastritis with age and sex in both stray and domestic animals. Gastritis was significantly more prevalent in antrum than body and only chronic nonspecific gastritis was diagnosed. The most common types of chronic nonspecific gastritis were atrophic (26.6%), lympho-plasmacytic (24.6%) and hypertrophic (15.3%) respectively. In chronic gastritis cases, fibrosis and lymphoid follicle was seen in 42.1% and 31.6% of the subjects respectively, but no significant association between type of nonspecific chronic gastritis, fibrosis and lymphoid follicle occurrence was seen. The prevalence of gastric erosion and ulcers in cats was 19.2% and 3.5% respectively and there was no significant association between chronic gastritis occurrence and gastric ulceration & erosions syndrome. Cytology examination showed GHLO infection rate of antrum and body 63.15% and 77.19% respectively, however there was no correlation between presence and degree of Helicobacter colonization and nonspecific chronic gastritis.
