Plain-English summary

A lethargic and weak American Staffordshire Terrier was diagnosed with a tick-borne infection called Babesia gibsoni, which caused anemia (low red blood cell count). Tests showed the presence of the parasite in the dog's blood. The study provided detailed images of the parasites inside the dog's red blood cells, helping to identify different forms of the Babesia organism. Treatment for this infection typically includes medications to eliminate the parasites and supportive care to help the dog recover. With appropriate treatment, many dogs can improve and regain their strength.

Abstract

Canine babesiosis is a tick-borne parasitic disease caused by the intraerythrocytic parasites, Babesia canis and Babesia gibsoni. A lethargic, weak, American Staffordshire Terrier (pit bull) dog, which had regenerative, normocytic, normochromic anemia, was shown by polymerase chain reaction analysis to be infected with B. gibsoni. Transmission electron microscopy of ethylenediamine tetraacetic acid-treated blood disclosed many well-preserved, intraerythrocytic babesia trophozoites. Four morphologic forms of babesia trophozoites are described (small spheres, small rods, irregular forms lacking pseudoinclusions, and large spheres having pseudoinclusions) and are compared with intraerythrocytic forms of B. canis and B. gibsoni described in other light and electron microscopic studies of in vivo and in vitro Babesia infections. This is the first detailed transmission electron microscopic study of canine B. gibsoni-infected red blood cells in North America.
