Detection of Gastric Helicobacter-like Microorganisms in Dogs=Kuņģa helikobaktēriju noteikšana savvaļas jenotsuņiem (Nyctereut

This study was done to evaluate the prevalence of Helicobacter-like microorganisms in the stomach of feral raccoon dogs (Nyctereutes procyonoides) from the Chonbuk province at the southwest part of Korea and of domestic dogs (Canis familiaris) from Latvia. Mucosal samples were taken from several places of cardiac, fundic, and pyloric gland region of the stomach to detect Helicobacter spp. by employing urease test, brush cytology, and light histological investigation. All sampled raccoon dogs and four domestic dogs from the five sampled animals showed positive urease test and presence of tightly spiraled Helicobacterlike microorganisms. A positive urease test was observed in 75.7% of all examined samples of raccoon dogs and in 67.0% of all samples of domestic dogs. Helicobacter-like microorganisms were detected in 98.5% of all examined samples of raccoon dogs and in 69.4% of samples of domestic dogs by brush cytology, and in 91.2% of all examined samples of raccoon dogs and in 68.2% of samples of domestic dogs by histological examination. Compared to gastric regions in feral raccoon dogs, the employed detection methods showed that almost all samples (100%) were positive for Helicobacter spp. in the cardiac gland region. Whereas in domestic dogs, all detection methods demonstrated 80% of positive samples in cardiac and 80% of positive samples in fundic gland region of the stomach. Urease test results were controlled after 10, 30, and 60 minutes. The amount of positive samples of raccoon and domestic dogs increased with the checking time, so it is important to check results of test after 60 minutes of reaction.
