Title: Influence of immunisation with enteropathogenic and non-enteropathogenic Escherichia coli on the occurrence of loop dilation in rabbits. Author: Molenda J, Kozyrczak J, Skurski A, Zwierzchowski J, Staroniewicz Z. Journal: Res Vet Sci; 1983 Jan; 34(1):1-4. PubMed ID: 6340171. Abstract: The protective effects of high levels of O115 antibodies and K88 antibodies in the sera of hyperimmunized rabbits on the intestinal loop dilation elicited by live cultures of Escherichia coli O115: K88:H39 and its enterotoxins were examined. K88 antibodies did not prevent fluid accumulation when live E coli O115:K88:H39 or its enterotoxins were injected into ligated loops in rabbits actively immunised with K12:K88 or when K88 antiserum was mixed directly with the challenge shortly before injection into the loops. In two of six rabbits immunised with heat-killed O115 E coli the live strain failed to elicit a fluid response and in two others the response was reduced. In all cases the O115 antiserum inhibited the fluid response evoked by the live, homologous bacteria, but not by enterotoxin preparations, when the serum was mixed directly with the challenge before injection.[Abstract] [Full Text] [Related] [New Search]
