Clinically the affected dogs showed severe respiratory distress within 48 h after arriving in the shelter. The dead were found mainly with nasal bleeding and hematemesis. At necropsy hemothorax and hemorrhagic pneumonia along with severe pulmonary consolidation was observed though histopathological analysis showed mainly hemorrhagic bronchopneumonia. Lymphoid depletion was inconsistently seen in the spleen tonsil and bronchial lymph node. Gram-positive colonies were shown in blood vessels or parenchyma of cerebrum lung liver spleen and kidney. Also Streptococcus S. equi subsp. zooepidemicus was isolated from the various organs in which the bacterium was microscopically and histologically detected. In addition approximately Kb specific amplicon antiphagocytic factor H binding protein was amplified in the bacterial isolates. In this study we reported an outbreak of canine hemorrhagic bronchopneumonia caused by S. equi subsp. zooepidemicus in an animal shelter in Yangju Korea. Keywords animal shelter canine hematemesis hemorrhagic pneumonia Streptococcus zooepidemicus Kennel cough is one of the most significant clinical problems in dogs and ubiquitous in intensively housed animal facilities such as breeding kennels and animal shelters 8 . The causes of kennel cough have been involved in the combination of microbial agents including viruses and bacteria and environmental factors such as crowded conditions and other stressors 8 . Among .
