|Abstract: ||Microbiological assessment of vibriois infected
blue damsel, Pomacentrus caeruleus reared in captivity in marine aquaria led to
isolation of five distinct Vibrio species. Cultural, morphological and
biochemical characteristics of these isolates identified them as Vibrio
alginolyticus (29.4%), V. vulnificus (26.8%), V. fluvialis (15.3%), V. pelagius (9.1%) and V. anguillarum (19.4%). Predominant Vibrio alginolyticus and V.
tested for pathogenicity and Koch postulate by experimentally infecting
apparently healthy blue damsels, P.
caeruleus. The lethal dose (LD50) was
1.36×106 and 3.44×106 CFU/g
fish (colony forming units) for V. alginolyticus and V. vulnificus respectively. All
the vibrios were highly susceptible to the broad spectrum antibiotics
Chloramphenicol (30 μg/disc), Erythromycin (15 μg/disc), Gentamycin (30 μg/disc)
and Oxytetracycline (30 μg/disc).
