The serum is tested by means ofcomplement fixation and agghitination reactions. Theanimals can also be tested by means of mallein (madefrom glanders bacilli), the injection of mallein being fol-lowed by a typical febrile reaction.

In man the infection occurs in two forms: the bubonic,involving the lymph-glands; the pneumonic, in\olv-ing the lungs. The disease is spread directly from manto man, especially in the pneumonic form, and alsofrom rats, ground squirrels, and other rodents to the latter case infection is usually intermediate through 180 APPLIED BACTERIOLOGY FOR NURSES fleas infesting these rodents.
