Normal serum bactericidal activity study were carried out against nine bacterial species (Mannheimia haemolytica, Staphelococcus aureus, Arcanobacterium pyogenes, Streptococcus pyogenes, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Bacillus subtilis, Moraxella ovis) isolated from pneumonial lungs in sheep by the use of a normal non immunized serum collected from normally healthy sheep, cattle, horses. All species of bacteria were resistant for serum effect except B. subtilis and Pseudo. aeruginosa which were sensitive for all types of serum, while Moraxella ovis was sensitive for horse serum only, but Pseudomonas aeruginosa and Bacillus subtilis were resistant to complement free serum.
