Abstract
A 79-year-old Japanese immunocompetent woman was admitted with high fever and left hip pain. T2-weighted magnetic resonance imaging showed fluid retention around the left hip. Salmonella enterica subspecies arizonae (S. arizonae) was detected in the puncture fluid of the left hip joint. After treatment with antimicrobials, the patient recovered well. Human infections with S. arizonae have been reported mostly in the southern United States, where contact with reptiles is common. Since 2000, only 6 cases of S. arizonae infection have been reported in Japan, non- endemic area. Although the patient had a history of reptile-contaminated food intake, the relation between the history of reptile-contaminated food intake and S. arizonae infection was unclear. Further accumulation of cases is important to elucidate the pathogenesis of S. arizonae infection in non-endemic areas.
