The human and animal pathogens
Yersinia pestis
, which causes bubonic and pneumonic plague, and
Yersinia pseudotuberculosis
and
Yersinia enterocolitica
, which cause
gastroenteritis
, share a type 3 secretion system which injects effector proteins, Yops, into host cells. This system is critical for virulence of all three pathogens in tissue infection. Neutrophils are rapidly recruited to infected sites and all three pathogens frequently interact with and inject Yops into these cells during tissue infection. Host receptors, serum factors, and bacterial adhesins appear to collaborate to promote neutrophil-
Yersinia
interactions in tissues. The ability of neutrophils to control infection is mixed depending on the stage of infection and points to the efficiency of Yops and other bacterial factors to mitigate bactericidal effects of neutrophils.
Yersinia
in close proximity to neutrophils has higher levels of expression from
yop
promoters, and neutrophils in close proximity to
Yersinia
express higher levels of pro-survival genes than migrating neutrophils. In infected tissues, YopM increases neutrophil survival and YopH targets a
SKAP2
/SLP-76 signal transduction pathway. Yet the full impact of these and other Yops and other
Yersinia
factors on neutrophils in infected tissues has yet to be understood.
