title: Aeromonas species in clinical microbiology: significance, epidemiology, and speciation.
abstract: Over a one-year period, 32 strains (31 clinical, 1 environmental) of Aeromonas sp. were recovered. Chief sources of isolation were the gastrointestinal tract (48%), wounds (19%), and blood (13%). Gastrointestinal isolates were most often recovered from young (less than 5 yrs) children with diarrhea; wound or blood isolates were recovered more often from an older (avg. 56 yrs) population with one of several underlying disorders. Regardless of body site of isolation, most strains of Aeromonas appeared to be community acquired and not nosocomially transmitted. Over 70% of all isolates recovered during this year period were isolated during summer or fall months, suggesting a seasonal distribution of this microorganism. Speciation of Aeromonas isolates revealed A. hydrophila to be the predominant species isolated from clinical specimens, although significant percentages of other Aeromonas sp. were also recovered from clinical material.
