“…No reports are available on the use of ENR for the treatment of francisellosis in Nile tilapia ( O. niloticus ), making this study the first to highlight that finding. Another study demonstrated the success of ENR treatment against Vibrio alginolyticus in Nile tilapia ( O. niloticus ) at a dose of 50 mg/kg of LW (El‐Gohary et al, 2020). In addition, studies have been conducted on the beneficial effects of ENR against bacterial pathogens in various fish species, including Aeromonas salmonicida infections in rainbow trout (Bowser et al, 1994) and Renibacterium salmoninarum and Aeromonas salmonicida infections in salmonids (Hsu et al, 1994, 1995).…”

Outbreaks of infections by Francisella orientalis represent one of the main obstacles to Nile tilapia (Oreochromis niloticus L.) farming. It is responsible for acute mortality in fingerlings and juveniles. The main control measure available is oral antibiotic therapy. This study compared the therapeutic efficacy of the antibiotics enrofloxacin and oxytetracycline, the most commonly used antimicrobial, against francisellosis in juvenile Nile tilapia (O. niloticus). Fish were challenged with a virulent isolate of F. orientalis and treated with medicated feed containing one of two doses of oxytetracycline (100 or 300 mg/kg of live weight (LW)) or 10 mg/kg of LW of enrofloxacin. The positive and negative control groups received feed without antibiotics; the negative control group was unchallenged. The results showed that enrofloxacin at a dose of 10 mg/kg of LW is effective against francisellosis in juvenile Nile tilapia (O. niloticus). Treatment with oxytetracycline did not eliminate the pathogen from the infected host, and the surviving fish became carriers. Enrofloxacin was able to cure the fish of infection with F. orientalis. This study suggests that enrofloxacin is a better option for treating francisellosis in Nile tilapia (O. niloticus L.). It controls mortality and avoids the carrier state in the fish, thus reducing the possibility of recurrence in the affected batches.

“…The most frequently utilized antibiotics are tetracycline and quinolone antibiotics, as well as sulfonamides, which are typically potentiated with trimethoprim. El-Gohary et al [ 19 ] reported that the mortality rate of infected Nile tilapia fish ( Oreochromis niloticus ) by V. alginolyticus was reduced after being treated with florfenicol (25 mg/kg), enrofloxacin (50 mg/kg), and oxytetracycline (50 mg/kg) for 7 days. In another study, orally administered 10 and 20 mg/kg of florfenicol, 25 mg/kg of oxolinic acid, and 25 mg/kg of flumequine were found to help lower cumulative mortality in lumpfish ( Cyclopterus lumpus ) infected by V. anguillarum [ 20 ].…”

Vibriosis is one of the most common diseases in marine aquaculture, caused by bacteria belonging to the genus Vibrio, that has been affecting many species of economically significant aquatic organisms around the world. The prevention of vibriosis in aquaculture is difficult, and the various treatments for vibriosis have their limitations. Therefore, there is an imperative need to find new alternatives. This review is based on the studies on vibriosis, specifically on the various treatments and their limitations, as well as the application of nanoparticles in aquaculture. One of the promising nanoparticles is graphene oxide (GO), which has been used in various applications, particularly in biological applications such as biosensors, drug delivery, and potential treatment for infectious diseases. GO has been shown to have anti-bacterial properties against both Gram-positive and Gram-negative bacteria, but no research has been published that emphasizes its impact on Vibrio spp. The review aims to explore the potential use of GO for treatment against vibriosis.

“…Antibiotics are the most commonly used method to control V. alginolyticus . The drug sensitivity test of V. alginolyticus infected tilapia showed that treatment with florfenicol, enrofloxacin or terramycin could reduce the mortality of infected Nile tilapia [ 92 ]. What is more, the results of another drug sensitivity test on V. alginolyticus identified in the hippocampus cultured in eastern China showed that it was highly sensitive to doxycycline and tetracycline as well [ 12 ].…”

It is estimated that vibriosis account for about half of the economic losses in Asian fish culture. Consequently, the prevention and control of vibriosis is one of the priority research topics in the field of Asian fish culture disease. Relevant measures have been proposed to control some Vibrios that pose a threat to Asian fish culture, but there are currently only a few effective vaccines available to combat these Vibrios. The purpose of our review is to sum up the main prevention methods and the latest control strategies of seven Vibrio species that cause great harm to Asian aquaculture, including Vibrio harveyi, Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio mimicus, Vibrio anguillarum, Vibrio alginolyticus and Vibrio cholerae. Strategies such as antibiotics, probiotics, bacteriophages, antimicrobials from plants and other natural sources, as well as vaccines, are compared and discussed here. We expect this review will provide some new views and recommendations for the future better prevention and control of vibriosis in Asian fish culture.
