The term “probiotic” was firstly used to denominate microorganisms that have effects on other microorganisms. Antibiotics are used extensively because diseases are the most important factor limiting production and trade in aquaculture. Intensive use of antibiotics causes resistance to antibiotics, adverse effects on human health and many damages in the ecosystem.
In aquaculture, research on the use of probiotics to stabilize the bacterial populations in the water, reduce pathological bacterial load and improve water quality is increasing and the use of probiotics is widespread. Probiotics are single or mixed live microorganism cultures or metabolites there of which promote the development of the intestinal microflora of the host organisms, cause recovery and rapid growth in the oral cavity, gastrointestinal system, upper respiratory tract. On the other hand, probiotics help to detoxify potentially harmful compounds in foods and feed them by feeding them with amylases and proteases, digesting potentially inaccessible elements in the diet, stimulating the production of vitamins and the congestive immune system. For these reasons it is important to identify antibiotic resistant strains and use them in aquaculture. In this study, 13 antibiotics (Kanamycin-K30, Penicillin-P10, Ampicillin- AM10, Erythromycin-E15, Clindamycin-DA2, Rifampin- RA5, Methicillin-ME5, Enrofloxacin-ENR5, Florfenicol- FFC30, Ciprofloxacin-CIP5, Nitrofurantoin-F300, Methicillin-ME5, Trimethoprim/ Sulphamethoxzole- SXT25) and 4 probiotic bacteria (Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus fermentum, Lactobacillus paracasei) were used.
