An Atlas of Salmonella in the United States, 1968-2011
About the Atlas
An Atlas of Salmonella in the United States, 1968-2011 [PDF - 248 pages] summarizes 42 years of laboratory-confirmed surveillance data on Salmonella isolates (pure strains separated from specimens with more than one bacteria) from humans.
- Analyses by age, sex, geography, and season
- Reports of Salmonella isolates from animals and related sources (e.g., environment and feeds)
This is the first time CDC has posted these data online in a downloadable format in its entirety or in 32 individual Salmonella serotype reports.
The Importance of Serotyping Salmonella
Scientists classify types of Salmonella into serotypes by identifying the structures on the bacteria’s surfaces. Since the 1960s, public health scientists in the US have used serotyping to link Salmonella cases with similar bacteria and likely to be related. Serotyping has been the core of public health monitoring of Salmonella infections since then. Now, scientists also use DNAtesting to further divide each serotype into more subtypes.
Additional Serotype Reports
In addition to the Salmonella Atlas, CDC has produced annual reports for National surveillance forSalmonella infections by year for 2007, 2008, 2009, 2010, and 2011. These reports contain a description of national surveillance [PDF - 12 pages] and summary data tables not contained in the Atlas.
