ABSTRACT
Campylobacter jejuni causa principalmente enteritis disenteriforme; los casos debidos a C. fetus son raros, mayormente bacteriemiaen inmunosuprimidos. Presentamos dos casos de enfermedad diarreica con bacteriemia, ambos con hemorragia digestiva,debida a C. jejuni, un caso inusual de infección de anerurisma de la arteria femoral y un caso de bacteriemia recurrente conprobable foco en marcapasos en un anciano sin otro factor de inmunosupresión, los dos últimos debidos a C. fetus. Todos lospacientes tuvieron evolución favorable. Recomendamos prestar atención a los hemocultivos que resulten positivos para efectuarlos subcultivos adecuados para recuperar, identificar y determinar la sensibilidad a los antimicrobianos de este tipo de bacterias microaerofílicas.
Campylobacter jejuni often causes enteritis; cases due to C. fetus are rare: it causes mostly bacteremia in patients with immunosuppression.We present two cases of diarrheal disease with bacteremia, both with gastrointestinal bleeding due to C. jejuni, an unusual case ofC. fetus infection of an aneurysm in the femoral artery, and one case of recurrent C. fetus bacteremia with probably focus in apacemaker in an elderly patient without another cause of immunosuppression. All patients had a favorable evolution. We recommendspecial attention to the positive blood cultures in order to recover and identify this type of microaerophilic bacteria, and determineantimicrobial susceptibility.
