Sanitary-bacteriological estimation of ctenophore in the Caspian and Black seas
Bacteriological studies of ctenophore showed that various microflora was separated from Mnemiopsis leidyi and Beroe ovata: Aeromonas hydrophila, Vibrio alginolyticus, Pseudomonas aeruginosa characteristic of the Black Sea; various pseudomonas, vibrios and acinetobacters typical of the Caspian Sea. The Black Sea A. hydrophila and P aeruginosa that exhibited markers of pathogenicity (photolytic, hemolytic, lecithinase activity, as well as DNAases) turned out to be virulent for fish and mice. It was established that during Beroe adaptation to Caspian water the Black Sea microflora was replaced by the Caspian one. Thus, when it is necessary to acclimatize Beroe ovata to Caspian water, ctenophore should be put in two-three weeks quarantine followed by control bacteriological examination.
