Phytobiotics and Their Antibacterial Activity Against Major Fish Pathogens. A Review

Abstract This review focuses on the characteristic of major fish bacteria, antimicrobial resistance and antibiotic substitution in aquaculture. Nowadays aquaculture represents fastest growing industry leading to use intensive semi-intensive methods resulting outbreaks bacterial diseases. Antibiotics are used treat prevent these diseases, which can cause an increase resistance. Many antibiotics applied were originally human medicine many countries do not have strict limits for their application. Annually, more than 700 000 people worldwide die from infections caused by bacteria resistant even though European rules antibiotics, death rate 33 per year. One options how resolve this problem is replacement with bioactive compounds plant origin that exhibit strong inhibitory activity against pathogenic bacteria.
