EXERCISE LXIV. BACILLUS VULGARIS (Hauser) Migula. 
PROTEUS VULGARIS. 
GENERAL CONSIDERATIONS. Described by Hauser in 1885 as Proteus vulgaris (Ueber Faulnis Bakterien). It is widely distributed 
and is commonly found in putrefactive substances. It is one of several related species included under the old name of ‘‘Bacterium 
termo.” While in small doses and under ordinary conditions it is harmless, at times and in large doses it may be pathogenic.
