Abstract

In this research, extraction, purification and inactivation of ESCHERICHIA COLI (E. coli) LIPOPOLYSACCHARIDE (LPS) were performed with the aim of investigating the effects of inactivated and intact form of LPS on CHICKEN humoral immune response stimulation. Also, the possibility of application of this outer part of cell wall for specific induction of humoral immune response to its reference bacteria was evaluated. The LPS was extracted using Ethylene diamine tetraacetic acid (EDTA). Four doses (10, 25, 50 and 100 mg) of inactivated and intact form of LPS and 100 mL of %20 sheep red blood cell (SRBC) were injected to eight groups of broiler CHICKENs (N=4). The humoral immune responses were evaluated five and 10 days after treatment by haemagglutination assay. The effects of LPS on induction of humoral immune response to the reference bacteria were measured using in-house ELISA. Injection of 10 and 25 mg of LPS significantly (P<0.05) induced the humoral immune response. The inactivated LPS only induced immune responses 10 days after the injection of 100 μg. No significant difference existed between the various groups in antibody titer against E. coli (P<0.05). It is possible to take advantage from ESCHERICHIA COLI LIPOPOLYSACCHARIDE in poultry immunization. Also, evaluation of the side effects and changes of inactivation methods may show the capability of LPS application in animal immunization. In addition, using LPS as a vaccine for E. coli is not suggested.
