A Histo-pathological Study of various Types of Chronic Gastritis in Stray Dogs

Gastritis is a common disease in dogs. According to studies, about 40% of dogs suffering from vomiting end up with chronic gastritis or those with no digestive symptoms reveal some levels of gastric histo-pathologic lesions. Studies on dogs and cats indicate that the most prevalent form of chronic gastritis is the lymphocytic plasmocytic form associated with lymphoid follicular hyperplasia and that the lesions are more likely to be seen in antrum. In order to assess chronic gastritis forms in stray dogs that seem to be at greater risk due to their probably poor nutrition and parasitic infections, this study as the first one in Iran was conducted on the antrum and body of the stomachs of 30 stray dogs killed under a culling program in Garmsar city assessing any possible correlation with the dogʹs age and sex. After the autopsy, histo-pathologic samples were prepared from the two areas, stained and finally examined. The results revealed that 56.6% of the dogs suffer from levels of chronic gastritis with the lymphocytic plasmacytic gastritis being the most common (50%) and hypertrophic gastritis the least common (6.6%). Antrum showed more lesions than body. Statistically there was no significant correlation between age groups or sexes with the disease. The results of this study indicate that chronic gastritis is respectively more prevalent in stray dogs than it is in other dogs; whereas poor nutrition and parasitic infections might be the reason behind this.
