† Micrococcus nigrofaciens Northrup
Source.—Diseased June beetle larvae.
Experimental infection.—Periplaneta americana, U.S.A. (Northrup, 1914): Three of four adults were infected by feeding them bread saturated with a broth culture of the Micrococcus. After 11 days the tarsi of the cockroaches became infected, and the hind legs split and broke off. Antennae and setae also were affected and micrococci were recovered from the feces.
