An in Vitro Study on the Antibacterial Activity of Kefir Milk, Labzyme, Biozyme and Some Antibiotics against Staphylococcus aureus and Escherichia colicauses Lameness in Broiler Chickens
Abstract: Bacterial chondronecrosis with osteomyelitis (BCO) is the most common cause of lameness in commercial broilers. Bacteria entering the blood via translocation from the respiratory system or gastrointestinal tract spread hematogenously to the proximal epiphyseal-physeal cartilage of rapidly growing femora and tibiae, causing BCO. We tested the hypothesis that probiotic kefir milk might attenuate bacterial translocation and thereby reduce the incidence of BCO. this study demonstrates that kefir possesses antibacterial effect against Staphylococcus aureus and Escherichia coli as compared with Labzyme, Biozyme and some antibiotics, Pencilin, Gentamycin, Tetracyclin and Newmycin. The results indicated that the Newmycin was the best significantly ( p < 0.05 ) against Staphylococcus aureus and Escherichia coli bacteria compared with others antibiotics, Labzyme, Biozyme and Kefir. Kefir was a highly significant ( p < 0.05 ) to inhibit the growth of Staphylococcus aureus and Escherichia coli bacteria as compared with Labzyme, Biozyme, Pencilin, and Tetracyclin.
