Anti‐ Vibrio activity of Pseudoalteromonas xiamenensis STKMTI.2, a new potential vibriosis biocontrol bacterium in marine aquaculture

Abstract

Vibriosis is a prevalent disease in almost all mariculture species worldwide. The pathogens causing this disease can survive freely in water regardless of the host and can very easily infect marine organisms in warm water (Klesius & Pridgeon, 2011). They cause the death of shrimp and marine fish (Istiqomah et al., 2020), which in turn leads to severe economic losses and becomes a major public health problem. These causative bacteria are classified as Gram-negative and opportunistic pathogens that infect the marine organisms when the host is under stress. Clinical signs of infected fish include anorexia, eyes opacity, pigmentation of the fish skin, skin ulcers, lesions in the muscle, exophthalmia, ulcers in the eye, fin rot, and swollen intestines (Mohamad et al., 2019;Zhang et al., 2014).Vibriosis is controlled by administering quinolone, tetracycline and erythromycin. However, the application of antibiotics strengthens the antibiotic-resistant Vibrio. Vibrio spp. have become resistant to antibiotics commonly used for treatment (Isnansetyo et al., 2009). Vibrio campbellii is resistant to oxytetracycline, ampicillin and carbenicillin (Nakayama et al., 2006). It has also been reported that some strains of V. harveyi have become resistant to more than three types of antibi-

“…However, we did not find references associating it with sole diseases, so its presence is potentially innocuous in our communities. The genus Pseudoalteromonas has been identified as a probiotic in aquaculture with anti-Vibrio activity (Handayani et al, 2021), although our study found no negative correlations between them. Finally, Thalassobius has also been described in marine RAS communities (Michaud et al, 2009), with species characterized as aerobic chemoorganotrophic marine bacteria (Pujalte et al, 2018), justifying their role in this environment.…”

“…Currently in both clinical medicine and aquaculture, antibiotics like quinolone, tetracycline, and erythromycin have been used to control vibriosis (Handayani et al 2022). Although there are many different antibiotics, the multidrug resistance problem has emerged and caused complicated cases (FB et al 2020;Li et al 2021;Yano et al 2014).…”
