Helicobacter species have commonly been isolated from the gastric mucosa of humans and animals, however have not been known its association with clinical signs. This study was aimed to detect and identify Helicobacter species in the canine stomach by urease test and polymerase chain reaction(PCR). A total of 87 dogs in Kangwon and Kyunggi areas from August, 1998 to June, 1999 were examined. The detection rate of Helicobacter species by urease test for fundal biopsy samples was 83.9%, and positive rate was increased as incubation time was increased. Helicobacter species was detected in the seventy seven dogs(88.5%) of total 87 dogs by PCR. The fifty five strains of the 77 strains of Helicobacter species were identified as H heilmannii and the three strains were identified as H felis by PCR, but the nineteen strains were not identified.

Helicobacter species have been identified in or isolated from domestic carnivores, but their prevalence in different population of animals and their clinical significance are still unknown. This study was peformed to evaluate the prevalence of Helicobacter in clinically healthy dogs by urease test, culture, morphological examination and polymerase chain reaction (PCR) technique. Tissue samples from 70 dogs in Kangwon and Kyunggi areas from August 1998 to April, 1999, were examined. The detection rates of Helicobacter by urease activity of tissue-samples were 84.6%, 61.3% and 4.8 % in the fundus, the antrum and the duodenum, respectively. One strain of Helicobacter was isolated from the duodenum. It was identified as H canis by biochemical and morphorogical examination. The detection rates of Helicobacter by histological examination were 92.3%, 79.0% and 4.8% in the fundus, antrum and the duodenum, respectively. Helicobacter organisms were colonized more in the gastric pits than in the surface of epithelium, the gastric gland or the parietal cell. Although most of dogs were colonized with Helicobacter in tissue, gross lesions and specific histopathological lesions caused by Helicobacter in these tissues were not observed. The detection rate of Helicobacter by PCR was 78.6%. The histological examination was more sensitive than urease test, culture or PCR technique for the detection of Helicobacter.
