Yersinia

A genus of bacteria in the Enterobacteriaceae family. The bacteria appear as gram-negative rods and share many physiological properties with related Escherichia coli. Of the 11 species of Yersinia, Y. pestis, Y. enterocolitica, and Y. pseudotuberculosis are etiological agents of human disease. Yersinia pestis causes flea-borne bubonic plague (the black death), an extraordinarily acute process believed to have killed over 200 million people during human history. Enteropathogenic Y. pseudotuberculosis and Y. enterocolitica typically cause mild chronic enteric infections. The remaining species either promote primary infection of fish (Y. ruckeri) or exist as secondary invaders or inhabitants of natural environments (Y. aldovae, Y. bercovieri, Y. frederiksenii, Y. intermedia, Y. kristensenii, Y. mollaretii, and Y. rohdei).

The predominant cause of acute Yersinia infection among children <5 years of age was bioserotype 3/0:3 (Table); 41 of 43 patients were infected with this bioserotype.
Compared with the 2013-2015 average annual incidence, the 2016 incidence of confirmed Campylobacter infections was lower, incidences of confirmed Shiga toxin-producing Escherichia coli (STEC), Yersinia, and Cryptosporidium infections were higher, and incidences of confirmed or CIDT positive-only STEC and Yersinia infections were higher.

Among the less common bacterial illnesses, Yersinia infections decreased by 49 percent, and Shigella infections declined by 35 percent.

During 1996-2007, 1,903 Yersinia infections were reported in FoodNet sites.
In 2011, FoodNet expanded surveillance to include the collection of epidemiologic and pertinent laboratory data on both culture-confirmed and positive CIDT reports of Campylobacter, Salmonella, Shiga toxin-producing Escherichia coli (STEC), Shigella, Vibrio, and Yersinia infections.
