GasparYR 2004 T1 Aeromonas molluscorum sp. nov., isolated from bivalve molluscs JF International Journal of Systematic and Evolutionary Microbiology, VO 54 IS 6 SP 2073 OP 2078 DO https://doi.org/10.1099/ijs.0.63202-0 PB Microbiology Society, SN 1466-5034, AB Five Aeromonas strains (848TT, 93M, 431E, 849T and 869N), which were isolated from bivalve molluscs and were recognized previously by numerical taxonomy as members of an unknown Aeromonas taxon, were subjected to a polyphasic taxonomic study. DNA–DNA hybridization experiments showed that DNA of strain 848TT was <70 % similar (27–45 %) to that of the type/reference strains of the current Aeromonas hybridization groups (HGs), but 93 % similar to that of strain 93M. The DNA G+C content of the five strains ranged from 59·0 to 59·4 mol%. 16S rRNA gene sequence analysis confirmed that the strains belonged to the genus Aeromonas and showed high similarity to Aeromonas encheleia. Amplified fragment length polymorphism fingerprinting clustered the novel strains in a homogeneous group with low genotypic relatedness to other Aeromonas species. Useful phenotypic features for differentiating the five isolates from other Aeromonas species include their negative reactions in tests for indole production, lysine decarboxylase, gas from glucose and starch hydrolysis. From the results of this study, the name Aeromonas molluscorum sp. nov. is proposed for these strains, with the type strain 848TT (=CECT 5864T=LMG 22214T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63202-0
