Abstract
A method of monitoring acute hepatopancreatic necrosis disease in shrimp is disclosed. More specifically, detection of the presence of alkaline phosphatase Phox enzyme, or, of the PiRAVP and/or the PirBVP toxins of acute hepatopancreatic necrosis disease-causing Vibrio parahaemolyticus correlates with non-virulence or virulence, respectively, of the bacterium is disclosed. Hence, an assay capable of detecting the Phox enzyme and/or the toxins could be very useful to monitor the disease in shrimp.
Claims10
A method of phenotyping Vibrio parahaemolyticus as non-virulent, the method comprising:
- utilizing presence of alkaline phosphatase Phox enzyme of V. parahaemolyticus as a marker to phenotype the V. parahaemolyticus as non-virulent.
A method of phenotyping Vibrio parahaemolyticus as non-virulent, the method comprising:
- utilizing molecules that bind to alkaline phosphatase Phox enzyme of V. parahaemolyticus to phenotype the V. parahaemolyticus as non-virulent.
An assay comprising:
- antibodies or fragments thereof that bind to the alkaline phosphatase Phox enzyme of Vibrio parahaemolyticus;
- and
- antibodies or fragments thereof that bind to PiRAVP and/or PirBVP toxin(s) of V. parahaemolyticus.
A process of phenotyping Vibrio parahaemolyticus as non-virulent, the process comprising:
- providing a sample;
- bringing the sample into contact with molecules that bind to alkaline phosphatase Phox enzyme of V. parahaemolyticus;
- and
- determining whether the alkaline phosphatase Phox enzyme of V. parahaemolyticus is present in the sample,
- wherein the V. parahaemolyticus is a non-virulent phenotype when the alkaline phosphatase Phox enzyme is present in the sample.
