[Aeromonas spp bacteremia: study of 12 cases and review of the literature]

Abstract

Twelve cases of Aeromonas spp. bacteremia are here reviewed in adult patients occurred at our institution during a 6-year period. Three cases corresponded to patients with hematological disease and four had a solid neoplasm. The source of infection in seven patients was extra-nosocomial; infections in the five remaining patients were considered to be acquired in the hospital. In seven patients, potential portals of entry were found. The usual clinical presentation was febrile syndrome in all cases and only in two patients did the clinical picture evolve to fulminant septic shock. Speciation of microorganisms was determined in only four cases: 2 A. hydrophilia, 1 A. caviae, and 1 A. veronii. Most isolates were susceptible to aminoglycosides, cotrimozazol, phosphomycin, and quinolonos, and resistant to ampicillin. Three patients (25%) died as a result of the infection. Aeromonas spp. bacteremia represented 0.12% of blood cultures in our hospital and occurs in immunosuppressed patients although it may be reported in previously healthy individuals.
