| 英文描述 | DIROFILARIA IMMITIS is the common canine heartworm in North America, but ANGIOSTRONGYLUS VASORUM can affect domestic dogs in many parts of the world. Heartworm occurs in cats, and clinical signs can be acute or chronic; coughing or dyspnea may indicate heartworm disease in cats. Adult heartworms live in the pulmonary arteries and right heart causing signs of pulmonary artery disease and right heart failure. May also cause syndromes of liver disease and hemoglobinuria, renal disease and proteinuria, allergic pneumonitis and eosinophilia. Occult dirofilariasis may account for 10-67% of all canine infections. Dx depends on signs, radiology, echocardiography, and adult heartworm antigen tests. Aberrant nematode migrations can occur to other parts of the body. Microfilaria can be seen in dogs under 6 months old due to transplacental migration. Skin disease associated with heartworm infection has been described. |
