Vibrio gallaecicus sp. nov. isolated from cultured clams in north-western Spain.

Abstract A group of three motile facultative anaerobic marine bacteria were isolated from cultured Manila clams (Ruditapes philippinarum) in Galicia, north-western Spain. The strains were characterized phenotypically and genotypically. Phylogenetic analysis of the 16S rRNA gene and four housekeeping genes, RNA polymerase α-chain (rpoA), RecA protein (recA), the α-subunit of bacterial ATP synthase (atpA) and the uridine monophosphate (UMP) kinase (pyrH), indicated that these strains were closely related to the Vibrio splendidus clade. The amplified fragment length polymorphism (AFLP) fingerprints, DNA–DNA hybridizations and phylogenies of the housekeeping and 16S rRNA gene sequences showed t…
