motile members of the genus Aeromonas, are among the most common and troublesome diseases of fish raised in ponds and recirculating systems. The widespread distribution of these bacteria in the aquatic environment and the stress induced by intensive culture practices predisposes fish to infections. Motile aeromonad infections have been recognized for many years and have been referred to by vari...
Mesophilic aeromonads are being increasingly reported pathogen of humans and lower vertebrates. Water and foods are considered to be the chief source of Aeromonas spp. At present there are several techniques available for the detection of Aeromonas spp. from water and foods. However, there is still need to develop immunodiagnostics for rapid detection of Aeromonas spp. irrespective of their spe...
Aeromonad virulence remains poorly understood, and is difficult to predict from strain characteristics. In addition, infections are often polymicrobial (i.e., are mixed infections), and 5-10% of such infections include two distinct aeromonads, which has an unknown impact on virulence. In this work, we studied the virulence of aeromonads recovered from human mixed infections. We tested them indi...
16S rRNA gene (rrs) is considered of low taxonomic interest in the genus Aeromonas. Here, 195 Aeromonas strains belonging to populations structured by multilocus phylogeny were studied using an original approach that considered Ribosomal Multi-Operon Diversity. This approach associated pulsed-field gel electrophoresis (PFGE) to assess rrn operon number and distribution across the chromosome and...
The diarrheal mechanisms in Aeromonas enteritis are not completely understood. In this study we investigated the effect of aeromonads and of their secretory products on ion secretion and barrier function of monolayers of human intestinal cells (HT-29/B6). Ion secretion was determined as a short-circuit current (I(SC)) of HT-29/B6 monolayers mounted in Ussing-type chambers. Transepithelial resis...
