Abstract
AIMS
To develop an assay for rapid screening of bacterial adhesion to various groups of biomolecules present in fish mucus.
METHODS AND RESULTS
A novel assay was developed for investigation of bacterial adhesion to various groups of mucus biomolecules from fish. Lipid-, protein-, carbohydrate- and nucleic acid-rich constituents of mucus were separated using isopycnic density gradient centrifugation techniques. Separated mucus fractions were assayed for bacterial adhesion using a blotting apparatus. The assay was validated using Vibrio vulnificus and skin mucus from hybrid tilapia.
CONCLUSIONS
A novel assay was developed for the screening of bacterial adhesion to major groups of mucus biomolecules. Adhesion of V. vulnificus MLT403 positively correlated with lipid- and protein-rich mucus constituents and negatively correlated with carbohydrate-rich mucus constituents.
SIGNIFICANCE AND IMPACT OF THE STUDY
The assay can be used as an initial approach in a systematic identification of mucus constituent(s) exhibiting the most favourable adhesion properties for bacteria.
