Brazil is one of the world’s leading producers Nile tilapia, Oreochromis niloticus. However, industry faces a major challenge in terms infectious diseases, as at least five new pathogens have been formally described last years. Aeromonas species are Gram-negative anaerobic bacteria that often fish causing Motile Septicemia (MAS). In late December 2022, an epidemic outbreak was reported farmed t...

AIMS To evaluate the relationship between the genomospecies, phenotypic profile and pathogenicity for carp of 37 motile Aeromonas strains. METHODS AND RESULTS Aeromonas strains were identified to genomospecies level by the 16S rDNA restriction fragment length polymorphism (RFLP) method and characterized phenotypically by the API 20E and API Zym systems and by conventional tube or plate method...

Motile aeromonads isolated from the intestines of farm-raised freshwater fish such as Catla catla, Labeo rohita and Ctenopharyngodon idella have been characterized to species level. Morphological and physiological grouping revealed 61% Aeromonas hydrophila, 30% Aeromonas caviae, 7% Aeromonas sobria and 2% which remained unidentified. Hemolytic activity was detected mostly in A. hydrophila, whil...

Aeromonas aquariorum, a recently described species, is associated with a variety of human diseases. We present here the first genome sequence of A. aquariorum strain AAk1, which was isolated as the sole pathogen from the blood of a patient with septicemia and necrotizing fasciitis.
