Abstract :

The present study was done to evaluate serum bactericidal activity of fresh serum samples of buffalo on staphylococcus aureus. Between November 2002 and May 2003, 78 serum samples were collected from buffalos in Ahwaz slaughterhouse .The bactericidal assay was performed by incubating dilutions of test strains with equal volumes of fresh or heat inactivated buffalo serum samples for one hour at 37°C .Bacterial count performed by pour plate method and the diminution of the bacteria as a result of bactericidal effect of fresh serum was calculated. The results showed that there was not any statistical difference (p<0/05 ) between fresh serum bactericidal activity of buffalos with different sex or age but there was a statistical difference between fresh and heat inactivated serums.
