Summary: | Abstract
The mechanisms through which brown‐marbled grouper accomplishes resistance to infection, particularly against
Vibrios
, are not yet fully understood. In this study, brown‐marbled grouper fingerlings were experimentally infected with
Vibrio parahaemolyticus,
to identify disease resistance grouper, and the serum proteome profiles were compared between resistant and susceptible candidates, via two‐dimensional gel electrophoresis (2‐
DE
). The results showed that putative parvalbumin beta‐2 subunit I, alpha‐2‐macroglobulin, nattectin and immunoglobulin light chain proteins were among proteins that significantly overexpressed in the resistant fish as compared to the susceptible group of fish, whereas apolipoprotein E and immunoglobulin light chain proteins were observed to be differentially overexpressed in the susceptible fish. Further analysis by peptide sequencing revealed that the immunoglobulin light chain proteins identified in the resistant and susceptible groups differed in amino acid composition. Taken together, the results demonstrated for the first time that putative parvalbumin beta‐2 subunit I, alpha‐2‐macroglobulin, nattectin and immunoglobulin light chain are among important proteins participating to effect disease resistance mechanism in fish and were overexpressed to function collectively to resist
V. parahaemolyticus
infection. Most of these molecules are mediators of immune response. |
