Immune response of rabbits immunized by killed whole cell sonicated E. coli 0157 antigen and crude Klebocin

Abstract

This present research was aimed to estimate the immune responses of rabbits immunized by KWCSA-E.coli 0157 and Klebocin during the period from November-2016 to May-2017. Thirty rabbits of both genders were randomly divided into six equal groups (5 animals for each group). Three types of tests were performed which were Skin Test (The delayed type hypersensitivity (DTH)), Tube Agglutination Test and ELISA. The Skin Test was performed at 18 days post immunization. The results showed an elevation in the means of erythema at 24hr of the 1st, 2nd, 3rd,4th and 5th groups which were 9.70, 8.90, 8.20, 6.00± 0.15 and 5.60 mm respectively. There was also a significant increasing (P
