Emerging Infections: Microbial Threats to Health in the United States
DIAGNOSIS
identification of the organism in patient's feces or in wound secretions
INFECTIOUS AGENT
Aeromonas hydrophila, A. veronii (biovariant sobria), A. caviae
other species of Aeromonas (A. jandaei, A. trota, A. schubertii, and A. veronii biovariant veronii) have also been associated with human disease
the natural habitats of Aeromonas bacteria are water and soil
MODE OF TRANSMISSION
ingestion of contaminated water
entry of organism through a break in the skin
DISTRIBUTION
presence of organism in clinical specimens has been documented in the Americas, Africa, Asia, Australia, and Europe
distribution is worldwide
INCUBATION PERIOD
undefined; probably 12 hours to several days
organism may persist for weeks to months in gastrointestinal tract
TREATMENT
antibiotics: trimethoprim-sulfamethoxazole, the quinolones, aminoglycosides, and tetracyclines
organisms tend to be resistant to penicillins and cephalosporins
PREVENTION AND CONTROL
proper treatment of drinking water and monitoring of well water
predisposed individuals should avoid aquatic environments
FACTORS FACILITATING EMERGENCE
predisposition (e.g., immunosuppression)
improved technology for detection and differentiation
increased awareness
Borrelia burgdorferi
DISEASE(S) AND SYMPTOMS
Lyme disease
distinctive skin lesion (erythema migrans) at site of tick bite that
