| Abstract: | The present paper compares the fluorescence-serological detection of M. hyopneumoniae and M. hyorhinis in frozen sections with cultural procedures. In 161 lungs of swine the agent of enzootic pneumonia, M. hyopneumoniae, was found almost exclusively in frozen sections (22 times). Only one strain was cultivable. M. hyorhinis was detected 59 times by culture but only 18 times in the sections. For the detection of M. hyopneumoniae therefore the fluorescence-serological investigation of lung sections is the preferable method. |
