MICROSPIRA SCHUYLKILLIENSIS 555 



The most characteristic lesions follow the injection of 

 cultures into the pectoral muscles of pigeons. At death 

 the inoculated muscle is swollen, necrotic, and the over-lying 

 tissues are edematous. The bacteria are found in large 

 numbers in the vicinity of the seat of the inoculation, 

 and in relatively small numbers in the blood and internal 

 organs.
