Interpretive Summary: Salmonella enterica subsp. enterica outbreaks have been caused by a wide variety of foods, indicating broad survival strategies for the organism. Likewise it is easily found in the environment among water, sediment, and wildlife. Serotype designation in Salmonella is based on antisera reactions to O- (lipopolysaccharide) and H- (flagellar) antigens, with isolates often containing more than one variety of each type of antigen. Strains RM11060 (serotype 6,8:d:-) and RM11065 (serotype 6,8:-:e,n,z15) were isolated from water and coyote feces, respectively during an environmental survey of Central California for foodborne pathogens (1). These two serotypes were encountered often during this survey, with serotype 6,8:d:- found in water samples, and 6,8:-:e,n,z15 found in soil, sediment, and wildlife samples. Both serotypes belong to the C2 serogroup, which includes serovars often implicated in outbreaks such as Newport and Muenchen. Subsequent surveys indicate that serotype 6,8:d:- is endemic to the region.
Technical Abstract: Salmonella enteric subsp. enterica strains RM11060, serotype 6,8:d:-, and RM11065, serotype 6,8:-:e,n,z15, were isolated from environmental sampling in Central California in 2009. We report the complete genome sequences and annotation of these two strains. These genomic sequences are distinct and will provide additional data to our understanding of Salmonella enterica genomics.
