NO. IO COCKROACHES—ROTH AND WILLIS 65 
gastroenteritis as all known species of Salmonella are pathogenic for 
warm-blooded animals, including man (Breed et al., 1948). 
Experimental vectors —Nauphoeta cinerea, Periplaneta australasiae, 
and Supella supellectilium, Australia (Mackerras and Pope, 1948) : 
This organism was recovered from the feces or guts of these cock- 
roaches. The longest invasions lasted 20 days in N. cinerea and 30 
days in S. supellectilium. 
Salmonella sp. (Type Kentucky) 
Synonymy.—Salmonella kentucky. 
Disease.—Isolated from chicken with coccidiosis and ulcerative 
enteritis ; also found in many species of fowl and in hogs and man. 
Natural vectors—Periplaneta americana, U.S.A. (Eads et al., 
1954): Organism isolated from cockroaches captured in sewer man- 
holes. 
Salmonella sp. (Type Kottbus) 
Synonymy.—Salmonella kottbus. 
Disease.—Acute gastroenteritis. 
Experimental vectors——Periplaneta australasiae, Australia (Mac- 
kerras and Pope, 1948): Three cockroaches were contaminated in 
the laboratory during tests with other species of Salmonella. The 
invasion lasted 18 days in one cockroach. 
Salmonella sp. (Type Meleagris) 
Synonymy— Salmonella meleagridis Brunner and Edwards. 
Disease.—I\solated from man, fowl, snakes. 
Natural vectors—Periplaneta americana, U.S.A. (Eads et al., 
1954): Organism isolated from cockroaches captured in sewer man- 
holes. 
Salmonella sp. (Type Montevideo) 
Synonymy.—Salmonella montevideo. 
Disease.—Organism isolated from humans, from an ape with fatal 
enterocolitis, and from chickens and powdered eggs. 
Experimental vectors.—Periplaneta americana, U.S.A. (Jung and 
Shaffer, 1952): The organism survived in the gut fairly regularly 
and persisted for at least 7 days when the insects had ingested feces 
containing approximately 10* or more viable S. montevideo (strain 
B-33). A second strain of this organism (5327) had less ability to 
persist in the cockroaches’ guts.
