“…Indeed, the implementation of efficient vaccination programmes in Norway during the nineties is nowadays considered a remarkable example of how alternative disease control methods can sharply reduce the use of antibiotics in intensive fish farming (Lulijwa et al, 2020 ). Presently, commercial Vibrio vaccines such as AquaVac™Vibromax™ (Wongtavatchai et al, 2010 ) and ALPHA JECT 3000 (PHARMAQ AS, Norway; see Torres-Corral et al, 2021 for an example of application) are available, which offer efficacy in vibriosis control in shrimp and finfish, respectively, under different administration methods, namely incubation of Artemia nauplii prior to shrimp feeding (AquaVac TM Vibromax TM ; see Amatul-Samahah et al, 2020 for a review on vaccination of shrimp against vibriosis) and intraperitoneal injection of adult fish (AlphaJect 3000).…”

Vibriosis Outbreaks in Aquaculture: Addressing Environmental and Public Health Concerns and Preventive Therapies Using Gilthead Seabream Farming as a Model System

Bacterial and viral diseases in aquaculture result in severe production and economic losses. Among pathogenic bacteria, species belonging to the Vibrio genus are one of the most common and widespread disease-causing agents. Vibrio infections play a leading role in constraining the sustainable growth of the aquaculture sector worldwide and, consequently, are the target of manifold disease prevention strategies. During the early, larval stages of development, Vibrio species are a common cause of high mortality rates in reared fish and shellfish, circumstances under which the host organisms might be highly susceptible to disease preventive or treatment strategies such as vaccines and antibiotics use, respectively. Regardless of host developmental stage, Vibrio infections may occur suddenly and can lead to the loss of the entire population reared in a given aquaculture system. Furthermore, the frequency of Vibrio–associated diseases in humans is increasing globally and has been linked to anthropic activities, in particular human-driven climate change and intensive livestock production. In this context, here we cover the current knowledge of Vibrio infections in fish aquaculture, with a focus on the model species gilthead seabream (Sparus aurata), a highly valuable reared fish in the Mediterranean climatic zone. Molecular methods currently used for fast detection and identification of Vibrio pathogens and their antibiotic resistance profiles are addressed. Targeted therapeutic approaches are critically examined. They include vaccination, phage therapy and probiotics supplementation, which bear promise in supressing vibriosis in land-based fish rearing and in mitigating possible threats to human health and the environment. This literature review suggests that antibiotic resistance is increasing among Vibrio species, with the use of probiotics constituting a promising, sustainable approach to prevent Vibrio infections in aquaculture.

“…Previous research on immunization trials against infectious diseases in shrimp required an incubation period ranging from 2 to 15 days after vaccine injection and prior to virus challenge to achieve optimum antiviral effectiveness (Amatul-Samahah et al, 2020). In preliminary Experiment 1 using an interval of 8 days between insect-cell homogenate injection and YHV-1 challenge, the Kaplan-Meier log-rank survival analysis revealed a significant difference (p<0.001) between the negative control Group A and both the YHV-1 challenged groups B (positive control) and C (YHV vaccination).…”

Shrimp vaccination with insect-adapted yellow head virus (YHV) extends survival upon YHV challenge

This short paper on yellow head virus Type-1 (YHV-1) describes preliminary research worthy of further study. YHV-1 disease outbreaks can cause severe mortality in the cultivated shrimp Penaeus (Penaeus) monodon and Penaeus (Litopenaeus) vannamei. No practical preventative treatment such as vaccination has been reported. However, it has been shown that C6/36 mosquito cell cultures can adapt to YHV-1 and become persistently immunopositive for the virus after 30 split-cell passages or more. Shrimp injection with homogenates from low passages caused yellow head disease (YHD) but from high passages did not, even though injection resulted in immunopositive hemocytes in the injected shrimp. This suggested YHV-1 attenuation during insect cell passaging and the possibility of using cell homogenates as a vaccine to protect shrimp against virulent YHV-1. To test this hypothesis, we injected shrimp with 30th passage homogenates to test for protection against YHD upon subsequent challenge with virulent YHV-1. Results confirmed earlier work that hemocytes of the shrimp injected with YHV-1 positive insect homogenates became both RT-PCR positive and immunopositive for YHV-1 but exhibited no mortality. Similarly, there was no mortality in the control group injected with homogenate from YHV-1 negative insect cells. When subsequently challenged with YHV-1, shrimp in the positive control group injected with homogenate from naive insect cells gave 100 percent mortality within 7 days post-challenge while total mortality in the group injected with YHV-1 homogenate did not occur until day 9 post-challenge. Kaplan-Meier log-rank survival analysis revealed that survival curves for the two groups were significantly different (p<0.001) and that the mean survival time for the test group (6.5 days) was significantly longer than that in the positive control group (5.4 days). The results confirmed that shrimp injection with YHV-1 immunopositive insect-cell homogenate gave transient resistance to YHV infection and that further research into the possible use of insect cell lines to produce shrimp antiviral vaccines is warranted.

“…Shrimp aquaculture has been plagued by disease and epizootics caused by bacterial (e.g., vibrio) and viral (e.g., white spot syndrome virus) pathogens over the last few decades (Naylor et al, 2021;Dhar et al, 2022;Rowley, 2022). To counter these, improvements in shrimp health have been pursued including development of antimicrobials but with their adverse consequences for the development of antibiotic resistance (Chi et al, 2017;Thornber et al, 2020;Sharma et al, 2021), vaccines (Rowley and Pope, 2012;Amatul-Samahah et al, 2020), biofloc technology pathogens of these animals. In response to evidence that probiotic administration results in significant improvement on growth and feed conversion (e.g., Balcázar et al, 2007), we also investigated whether delivery of a commercial strain of L. plantarum used in probiotic preparations for humans in feed has any effect on the growth potential of P. vannamei.…”

Antagonistic Activity of Lactic Acid Bacteria Against Pathogenic Vibrios and Their Potential Use as Probiotics in Shrimp (Penaeus vannamei) Culture

et al. 2022

Probiotic use in aquaculture settings can be an approach for disease control and dietary supplementation. We assessed the antagonistic effect of culture supernatants of lactic acid bacteria on the growth of known shrimp pathogens, Vibrio (Listonella) anguillarum, Vibrio alginolyticus, and V. harveyi, using a quantitative microplate bioassay. Supernatants from Lactobacillus curvatus subsp. curvatus, L. plantarum, and Pediococcus acidolactici significantly inhibited the growth of these vibrios. The active component(s) were heat stable (> 100°C) and resistant to freeze-thawing. Most of this inhibitory activity was brought about by the production of an acid pH; however, there was evidence for other factors playing a role. In the search for novel probiotic bacteria, an organism was isolated from the gastrointestinal tract of healthy whiteleg shrimp (Penaeus vannamei)—identified tentatively as Carnobacterium maltaromaticum. This isolate, however, had less potent vibriocidal activity than the lactic acid bacteria and reduced shrimp survival at a dose of 1 × 107 bacteria/shrimp. During a 28-day feeding trial, juvenile P. vannamei fed with L. plantarum supplemented diets showed no gross changes in growth parameters compared with the control. We suggest that lactic acid bacteria could be incorporated into biofloc formulations to purge the growth of pathogenic vibrios in pond settings, rather than being fed directly to shrimp.
