Identification and epidemiological relationships of Aeromonas isolates from patients with diarrhea, drinking water and foods.

摘要: A collection of Aeromonas isolates obtained over a three-year period in the same geographic area (Leon, NW Spain) was characterized by (GTG)₅-PCR fingerprinting, amplified fragment length polymorphism (AFLP) analysis and gyrB gene sequence analysis. The originated from human diarrheal stools (29 isolates), potable water (13 rabbit meat isolates) marine fish (5 isolates). distribution species varied with strain source. caviae HG4 media HG5 were predominant clinical isolates, respectively, whereas motile salmonicida HG3 strains most frequently found meat. Molecular typing revealed several genotypic relationships among specific isolate subsets: (i) two clones A. persisted drinking study period, (ii) different patients harbored identical or closely related during months, (iii) clonal relatedness observed sets isolates. first these comprised nine other one included HG4. latter finding suggests that transmission studied region followed waterborne route. Interestingly, three to recovered four days June 2006 non-related without underlying medical conditions tested negative for enteric pathogens. data imply through contaminated group can produce disease humans.
