Recurrent Soft Tissue Abscesses Caused by
Legionella cincinnatiensis
) gammopathy of unknown etiology. Conventional cultures remained negative, despite visible gram-negative rods on
microscopy. Broad-spectrum PCR revealed Legionella
cincinnatiensis, which was confirmed by isolation of the
organism on special Legionella medium. Infections due to
Legionella species outside the lungs are rare. L.
cincinnatiensis has been implicated in only four cases of
clinical infection; these involved the lungs in three patients and the
central nervous system in one patient. We conclude that broad-spectrum
PCR can be a valuable tool for the evaluation of culture-negative
infections with a high probability of bacterial origin and that
Legionella might be an underdiagnosed cause of pyogenic
soft tissue infection.
