In this study the researchers examined the anti-bacterial resistance of the bacterial infection, Pseudomonas aeruginosa, in Nile Tilapia, Oreochromis niloticus AND they tried Levamisole in the fish food, to check the result after challenged infection with the Pseudomonas.
They find that many strains of Pseudomonas were resistant to antibiotics and that the anti-worm medication Levamisole , with750mg/kg fish food, improved survival rate drastically! A now potential choice to combat bacterial infections?

I recommend this study for all importers of ornamental fish!!!
Why? It might have a serious impact on our fish industry due to strict quarantine regulations that can be implemented in your country!
This study reports the results of a nationwide parasitological survey that was conducted from 2019 to 2022 to investigate the potential introduction of monogenean parasites into India via the ornamental fish trade. A total of 619 individual exotic ornamental fish representing 27 teleost species from nine families were collected from major aquaria markets and examined for monogeneans. 26 monogenean species from 12 known genera were detected and identified in 17 of the 27 fishes examined.
