[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.

[Natural and experimental infections of lambs with Mycoplasma ovipneumoniae].

Mycoplasma (M.) ovipneumoniae was isolated pure or mixed with bacteria from 47 lungs of lambs of 14 in 22 tested flocks. M. ovipneumoniae was obtained as pure culture in cases of mild bronchopneumonia. Experimental intratracheal or intranasal infection caused several days of rising body temperature above 39.7 degrees C. Nasal discharge, coughing, and dyspnea did not occur. M. ovipneumoniae was successfully re-isolated from nasal swabs, beginning 2 d from infection. Lobular catarrhal bronchopneumonia was established by postmortem examinations, 10-14 d from infection, and M. ovipneumoniae was re-isolated from the lungs. Histological patterns of lungs were characterised by interstitial cell reactions.

[The reproduction of eperythrozoonosis of swine by animal experiments after splenectomy].

An account is given in this paper of equipment, techniques, clinical tests, and investigations for laboratory diagnosis required for an animal experiment on splenectomised store pigs suspicious of eperythrozoonosis (EEZ). The clinical, bacterioscopic, haematological, and biochemical data recorded from the experiment on splenectomised store pigs with suspicion of EEZ were helpful in reproducing both symptoms indicative of EEZ and relevant parameters of laboratory diagnosis. The diagnosis of EEZ, made in the first place on the basis of clinical, bacterioscopic, and haematological findings, was thus confirmed. Conclusions of general validity for users of animal experiments for EEZ diagnosis were also drawn and will prove helpful in establishing safe diagnosis in dubious cases. The animal experiment proved useful in following up the interactions between all parameters checked, which will contribute, no doubt, to better understanding of the pathophysiological processes associated with this disease.
