What is Enteropathogenicity of Aeromonas species isolated from infants: A cohort study about?

The significance of Aeromonas spp. as potential enteric pathogens was evaluated in a cohort of I87 infants aged 3-I8 months during a I6-week summer period. Aeromonas spp. were isolated from I4 of the I96 (7"I %) diarrhoeal episodes detected and from eight (5"2 %) of I53 samples from paired asymptomatic infants. Carriage of bacterial enteropathogens excluding Aeromonas spp. was detected in a high proportion (23 %) of the asymptomatic children. Almost all of the seven isolates of Aeromonas sobria were enterotoxigenic, invasive and beta-haemolytic. In contrast, none of the seven Aeromonas caviae strains had these virulence-associated characteristics. The only isolate of Aeromonas hydrophila produced cytotoxic enterotoxin and was invasive. Plasmid analysis of selected strains did not correlate with these two properties or with antibiotic resistance. Nevertheless, the latter was found in an important proportion of the isolates. The diarrhoeal episodes, in which Aeromonas spp. were detected, lasted significantly longer, i.e. I7"2 days when the strains were invasive and/or toxigenic as compared with 4"3 days (P < o.ooi) in patients harbouring strains lacking both traits. These results rei
