Isolation of bacteriophage 14-lysogenized Salmonella from the freshwater aquarium snail Apullaria

Abstract

A naturally occurring Salmonella mikawasima serologically converted by phage 14 (6,7,14:y:e,n,z15) has been isolated for the first time. An S. tennessee variant seroconverted by phage 14 (6,7,14:z29:-) was also isolated. The source of these salmonellae was the common freshwater aquarium snail Ampullaria. Phage 14 prepared from these serovariants was lytic for S. bovis morbificans (6,8:r:1,5) and for S. hadar (6,8:z10:e,n,x).
