Abstract

Cold haemagglutinin disease (CHD) was diagnosed in two newborn French bulldog pups. Necropsy revealed cyanosis and necrosis, formation of crusts on all anatomic extremities and amputation of the lower parts of the hind limbs. Histologically, cutaneous necrosis was found on the limbs of both animals, with blood vessel thrombosis, hemorrhages and predominantly neutrophilic infiltration, which affected the periosteum of the metatarsal bones. The surfaces of the necrotic areas were covered with thick crusts with Gram positive bacterial colonies. In the spleen and liver erythrophagocytosis was present. Lung congestion, alveolar edema and thrombosis of pulmonary artery branches, cerebral and chorioidal vessels were present. Immunohistochemicaly, lymphocytes and plasma cells in necrotic tissue were positive for IgM. Bacteriological examination of swabs from necrotic areas revealed the presence of Staphylococcus aureus. The diagnosis of CHD was based on macroscopic and histopathologic findings, which were identical to those described in literature and were supported by immunohistochemical reactivity to IgM.
