Salmonella enteritidisprimary bacteremia in previously healthy patient from Taiwan: case report.
BACKGROUND
Diseases caused by invasive nontyphoidalSalmonellastrains present with various extraintestinal manifestations, including bacteremia. Factors affecting the incidence includeSalmonellaserotype, geographic location, and host factors.


METHODS
We present an unusual case ofSalmonella enteritidisprimary bacteremia in a patient without any risk factors and originating from a region with the lowest burden of invasive nontyphoidalSalmonellainfections. We observed an incomplete clinical response to the treatment with a third-generation cephalosporin, despite thein vitrosusceptibility of the strain.


CONCLUSIONS
The diagnosis ofSalmonellabacteremia was far from expected in our previously healthy patient from Taiwan, without any preceding diarrhea and the lack of marked response to therapy with ceftriaxone. Making the diagnosis was a challenge, requiring wide range of laboratory, imaging, and consultative work to rule out alternative diagnoses and complications.


CONCLUSIONS
InvasiveSalmonellainfections are uncommon in our clinical practice at the present. Air transportation, intensive migration processes, and changes in climate are able to change the burden of infectious diseases dramatically in the near future. That fact along with the raising antibacterial resistance among invasive nontyphoidalSalmonellastrains make imperative the profound understanding of the epidemiology and pathophysiology of those infections.
