First insights of the Danube sturgeon (Acipenser gueldenstaedtii) skin adherent microbiota

This study assesses the microbial composition associated with the skin of Acipenser gueldenstaedtii, emphasizing species that are adherent. Various growth media were employed to cultivate samples collected from a group of 12 sturgeons from the same batch, revealing a diverse and atypical bacterial population. Notably, Ralstonia pickettii is documented here for the first time, as there have been no prior associations reported between this species and either wild or aquaculture sturgeon populations, to the best of our knowledge. The identification of presented adherent and non-adherent species raises questions and concerns regarding the existing microbial communities in sturgeons.
