PhD thesis, Universiti Sains Malaysia.
Abstract
Four experiments were carried out to evaluate the in vitro and in vivo used of
Lactobacillus acidophilus as a biocontrol agent against some common fish pathogenic
bacteria (Staphylococcus xylosus, Aeromonas hydrophila gr.2 and Streptococcus
agalactiae) and its effects on growth performance, hematological parameters, and
histopathology of African catfish, Clarias gariepinus. In the first experiment, the
antimicrobial activity of L. acidophilus against common fish pathogenic bacteria was
studied in vitro. In the second experiment, 2 experimental diets were formulated
comprising of a control (non-probiotic diet) and a L. acidophilus supplemented at a
concentration of 3.01 x107 colonies per gram of diet (probiotic diet).
