*{+}Background:+* _Salmonella enterica_ subsp. _enterica_ serovar Agona (antigenic formula 1,4,\[5\],12:f,g,s:\[1,2\]) is a serovar of the O:4 (B) serogroup. _S._ Agona is among the 15{^}th^ most common serovars in humans the U.S., and the 4{^}th^ most common serovar in clinical non-human sources. This serovar was first isolated from cattle in Ghana in 1952, since then numerous [outbreaks|http://www.cdc.gov/salmonella/agona-papayas/index.html] in the U.S. and [Europe|http://www.ncbi.nlm.nih.gov/pubmed/20950515] have occurred. Multi Locus Sequence Typing (MLST) has identified only four sequence types. Genome sequencing of 72 strains from multiple countries and sources was recently reported by [Zhou et al., 2013|http://www.plosgenetics.org/article/info%3Adoi%2F10.1371%2Fjournal.pgen.1003471].  

Animal reservoir: Different animal species, including turkey, swine and cattle are reservoirs of S. Agona.

Geographical distribution: Serovar Agona is among the most common serovars in North and South America, Europe, and Asia. In China, it is among the 10th most common serovars.

Outbreaks: Outbreaks linked to Salmonella Agona have been associated with different foods, including cereal, meat and fruits.
