The Genus Aeromonas : Biochemical Characteristics ...

The genus Aeromonas has undergone a number of taxonomic and nomenclature revisions over the past 15 years. Although originally placed in the family Vibrionaceae (), which also included the genera Vibrio, Photobacterium, and Plesiomonas, subsequent phylogenetic investigations indicated that the genus Aeromonas is not closely related to vibrios but rather forms a monophyletic unit in the γ-3 ...

Aeromonas Species - Infectious Disease and Antimicrobial ...

MICROBIOLOGY. Aeromonads, belonging to the genus Aeromonas, family Aeromonadaceae, are oxidase-producing gram-negative rods, grow on MacConkey agar and ferment carbohydrates.Separation from Vibrio species depends on resistance to the O/129 compound, no growth in 6% sodium chloride and absence of ornithine decarboxylase (except in A. veronii biovar veronii) ().
