Even though the last review about the taxonomy, pathogenicity and infections produced by Aeromonas was published fairly recently, in 2010, eight new species have since then been incorporated into the genus. Interestingly during this period the species Aeromonas dhakensis, that resulted from the reclassification of Aeromonas aquariorum and Aeromonas hydrophila subsp. dhakensis, became a relevant clinical species when sequences of housekeeping genes were used for identification. This species prevailed in Malaysia above the typical dominating clinical species Aeromonas caviae and Aeromonas veronii, or showed an almost equal frequency in Australia or Taiwan. The most frequent clinical presentation remained gastroenteritis, and arguments in favour of considering Aeromonas a true enteropathogen are provided. Other common presentations like wound and soft tissue infections have continued to be reported and seemed to prevail in European studies, while bacteraemia affecting patients that have hepatobiliary disease or cirrhosis continued to be dominating in Asia (Thailand, Taiwan etc). New cases of necrotizing fasciitis, pneumonia after near drowning and infections after leech therapy have also been reported during this period. This chapter pretends to make clinicians more familiar with the infections produced by these bacteria providing tools for their correct identification read more ...
