An epidemic among English sparrows due to Bacillus cloacae, T. II. Glenn 

 (Jour. Infect. Diseases, 6. {1909), No. 3, pp. 339-3.'i5) .—"^^ bacillus isolated 

 from the blood of sparrows during an epidemic among these birds was the 

 probable cause of their death, since it was obtained in pui'e culture from all 

 that died, and similar symptoms were produced in pigeons inoculated with it. 

 By passing the bacillus through animals, its virulence was increased so that it 

 became pathogenic for guinea pigs and rabbits. So far as can be determined 

 from the description given by other observers this bncillus resembles very 

 closely certain bacteria isolated by them in bird epidemics and called by them 

 B. eoli or coli-like organisms. The bacillus found in sparrows gives all the 

 cultunil characteristics o/ B. elonew, a member of the proteus group."
