Plain-English summary

A 5.5-year-old Siamese cat was brought to the vet because it had not been eating and seemed very tired for three days. During the exam, the vet noticed that the cat was depressed, dehydrated, had a fever, and showed signs of pale gums and a heart murmur. X-rays of the chest showed serious lung problems and enlarged blood vessels. Unfortunately, despite being hospitalized, the cat developed trouble breathing and passed away. A postmortem examination revealed that the cat was infected with a parasite called Cytauxzoon felis, which is known to cause serious illness in cats.

Abstract

A 5.5-year-old Siamese presented for evaluation of a three-day history of anorexia and lethargy. Upon physical examination, the cat was depressed, dehydrated, pyrexic, had injected conjunctiva and sclera, pale mucous membranes, and a grade II/VI systolic heart murmur. Thoracic radiographs revealed moderate to severe, diffuse, bronchointerstitial pulmonary changes with enlarged and tortuous pulmonary vessels. With continued hospitalization, the cat became dyspneic and died. The postmortem cytopathological examination of the liver, spleen, and lung impressions revealed reticuloendothelial cell infection with Cytauxzoon felis.
