Özet
The intensive use of antibiotics in aquaculture has resulted in increased resistance
among fish pathogens, and this situation has led researchers to investigate the antibacterial
properties of natural resources. The present study focused on an essential oil isolated from
the leaves of Eucalyptus camaldulensis as a potential antibacterial that could be used against
Aeromonas caviae. Eighteen compounds were identified in the essential oil, representing
86.68 % of the total oil. The components were found to be p-cymene (20.09%), βphellandrene (18.61%), α-phellandrene (7.50%), α-terpineol (6.02%), terpinen-4-ol
(5.50%), Crypton (5.36%), spathulenol (4.26%), linalool (3.56%), 1,8-cineole (2.77%),
farnesol (2.31%) Cumin aldehyde (2.13%), limonen (2.12%), α-thujene (1.94%), fellendral
(1.13%), γ-terpinene (1.10%), sabinene (0.97%), α-pinene (0.68%) and α -terpinen (0.63%).
The antibacterial efficiency of essential oils against Aeromonas caviae was determined
using Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal
Concentration (MBC) values, ranging from 200 µg/ml to 400 µg/ml respectively. Our
findings revealed the potential of essential oils isolated from Eucalyptus (Eucalyptus
camaldulensis) as a natural antibacterial agent that could efficiently contribute to the
control of Aeromonas caviae infection in fish.
