Clinical observations on eperythrozoonosis.

Abstract

Eperythrozoonosis was diagnosed in 23 herds of swine. Icterus and anemia were the major diagnostic criteria, with low packed cell volumes confirming the clinical impression of anemia. Indirect hemagglutination titers provided an indirect measure of infection rates and appeared to correlate positively with severity of signs. Treatment with oxytetracycline and arsanilic acid controlled the disease, but only when combined with efforts to limit transmission of the causative organism through control of lice.
