This study was attempted to survey on the prevalence of canine heartworm(Dirofilaria immitis) infections among 206 dogs (male 92, female 114) in Daejeon area from March to December 2003. Blood samples taken from dogs were examined for the presence of D immitis microfilaria by the modified Knott`s test and an antigen test(AGENTM canine heartworm). The result obtained from this experiment were summarized as follows; 1. Eighteen(8.7%) of the 206 examined dogs were microfilaria positive, while twenty five dogs(12.1%) were antigen test positive. 2. The infection rates of heartworm in dogs at the age of <2, 2~4 and >5 were 3.8%, 18% and 25%, respectively. 3. The infection rates of heartworm in dogs by housing of indoor and outdoor were 3.3% and 36.4%, respectively. 4.

Japanese enceplvlitis virus(JEV) antibodies in sera were detected by the haemagglutination inhibition test. The prevalence rates of JEV antibodies were 99.1%, 54.0%, 63.0% and 98.7% in cattle, pigs, chickens and dogs, respectively. In case of cattle and dogs, the monthly antibody-positive rates were as high as 85.7-100.0% and there were no differences among six months. In case of pigs, the monthly antibody-positive rate showed the lowest in April(6.4%) and the highest in July(100.0%) and it remained above 50% during the summer-time. In case of chickens, the monthly antibody-positive rate was 100.0% in July & August, 80.5% in June, 40.0% in May, 7.5% in September and 5.0% in April in order and there were distinct differences in seasons.
