[Infection model for the reproduction of eperythrozoonosis in splenectomized SPF primary piglets]

Reported in this paper is an infection experiment in which whole blood infected with Eperythrozoon (Ep.) suis was applied to bacterioscopically Ep. suis negative SPF primary piglets for the purpose of doubtless diagnosis of eperythrozoonosis (EEZ) of swine. EEZ could thus be clinically, bacterioscopically, haematologically, biochemically, pathologico-anatomically, and histologically reproduced. Such experimental infection, on top of splenectomy of EEZ-suspicious store pigs, was found to be an additional step for adequate diagnosis on the basis of animal experiments. Immediate and reliable diagnosis of EEZ was found to be generally possible solely by clinical, bacterioscopic, and haematological examinations.
