Abstract/OtherAbstract:
Laboratory findings in an adult bull terrier presented with a history of anorexia and weight loss included the following: severe anaemia, leukocytosis, neutrophilia, lymphopaenia, thrombocytopaenia, Ehrlichia canis morulae in monocytes, hypergammaglo-bulinaemia, a bleeding tendency, icterus and proteinuria. In addition, a high Haemobartonella canis parasitaemia, non-encapsulated yeasts on urinalysis and a localised Demodex canis infestation were present. Treatment for ehrlichiosis was initiated but the dog died. Lesions found were a severe cryptococcal granulomatous pneumonia and cryptococcal colonies in the lungs, bronchial lymph nodes, kidneys, liver, spleen, heart, meninges, eyes and thoracic cavity. In addition, hyphal forms resembling Filobasidiella neoformans, the teleomorph of Cryptococcus neoformans, were seen in lung fine needle aspiration smears, impression smears and lung sections. C. neoformans was cultured from urine, lung and liver. Lung and kidney also yielded Salmonella typhimureum. Cortical atrophy with T-cell depletion of lymph nodes as well as splenic lymphoid follicular atrophy, typical of chronic ehrlichiosis-induced cell mediated immunosuppression, could have predisposed to the fatal disseminated cryptococcis.
