Abstract

Vibrio infections are a major impediment to the sustainable expansion of the aquaculture industry worldwide. Early detection of vibriosis in aquaculture systems can protect not only fishes but also save economy. A novel Aquapatho kit was engineered for the specific detection of Vibrio bacteria in water samples, utilizing a selective medium that enhances the growth of Vibrio species while inhibiting other bacterial growth. This selective medium facilitates the identification of active Vibrio bacteria by inducing a color change to red/orange. The kit’s efficacy was initially tested using two Vibrio species, Vibrio cholerae and Vibrio parahaemolyticus, along with two negative control bacteria, Escherichia coli and Bacillus cereus. Subsequent validation was conducted on water samples from aquaculture ponds and biofloc-based aquaculture farms. The kit effectively quantified Vibrio concentrations for both tested species in the aquaculture environments, while the negative controls did not elicit a response. Thus, this kit demonstrates high specificity and reliability for detecting Vibrio bacteria in aquaculture settings.
