| Abstract: | Present study was performed to validate the potential of mangrove, Excoecaria agallocha leaves against
Aeromonas hydrophila isolated from infected marine ornamental
fish, Amphiprion sebae.
Infected ten fish samples were collected from the marine ornamental fish
hatchery and the bacteria was isolated and identified as Aeromonas hydrophila. Antibiotic resistance characterization was
performed with commercial antibiotics. In vitro antibacterial activity
of methanol and acetone extract of Excoecaria
agallocha and their minimum
inhibitory concentration (MIC) were assessed. Healthy Amphiprion sebae when challenged with the Aeromonas hydrophila,
resulted in the development of clinical signs, those observed in the hatchery. The methanol extract of Excoecaria
agallocha leaf was administrated
with live A. hydrophila, decreased the percentage of mortality in the
experimental groups. The
phytochemical screening of the extract showed
the presence of alkaloids, phytosterols, fixed oils and fats, tannins,
phenolic compounds, proteins, free amino acids, gums, mucilage, flavonoids and
lignin. The
results revealed that the Excoecaria
agallocha leaves have the
potential to control the Aeromonas
hydrophila diseases in marine ornamental fish, Amphiprion sebae. |
