Biochemical profile of liver of Indian major carp (Labio rohita) exposed to immunostimulant and bacterial infection

ABSTRACT

The efficacy of oral feeding diet (supplement) Aqua Fix was studied  on the biochemical changes in liver and immune response with  regard to biochemical profile against aeromoniasis in L.rohita. Three groups(A,B,C) of six months old fish were employed; groups A and B were treated with Aqua Fix  for 4 days, on day 5 fish of group B and C were infected with Aeromonas hydrophila @ 10^-6CFU/fish(fish of  group C were fed with normal diet for 4 days).Controls (group D) were untreated and uninfected. Necropsies were made on day 1, 2,3,4,7 and 15 after infection in fish of group B and C; fish of group A and D were also necropsied on same designated days. Liver protein, carbohydrate, DNA and RNA were estimated following standard methods and results were subjected to statistical analysis and found that the immunostimulant modulated immunity to enhance the level of protein, carbohydrate, DNA and RNA in liver. Stress caused by aeromoniasis led to the decrease of all the above biomolecules in fish  which received infection (group C) .

Key words: Liver, Immunostimulant , Aeromonas hydrophila , Labeo rohita.
