YERSINIA INFECTIONS : CLINICAL ASPECTS

Both Y.enterocolitica and  Y. pseudotuberculosis cause  acute  mesenteric lymphadenitis, a syndrome  involving  fever and  abdominal  pain that often mimics acute  appendicitis.Y. enterocolitica also produces awidervarietyof manifestations. Themost common of these is an enterocolitis, which usually occurs in children. It is characterized by fever, di- arrhea, and abdominal pain. It also causes enteric fever, terminal ileitis, and a polyar- thritic  syndrome  associated  with  its  diarrheal  manifestations.  Few  laboratories  in  the United States routinely screen stools for Yersinia, because yield has been low and good selective media are not available.

The role of antimicrobial therapy in the enteric Yersinia infections is uncertain, be-cause they are usually self-limiting. Y. pseudotuberculosis is susceptible to ampicillin, cephalosporins, aminoglycosides, tetracyclines, and chloramphenicol, butY. enterocoliticais  usually  resistant  to  penicillins  and  cephalosporins  through  the  production  of lactamases.
