Passive immunization of piglets against enterotoxigenic colibacillosis by vaccinating dams with K88ac pili bearing bacterins.
Day-old-piglets were passively immunized by vaccinating the pregnant sows with K88ac enterotoxigenic Escherichia coli (ETEC) vaccine. High level of ETEC specific antibodies was excreted in colostrum (3733.33 +/- 1152.13) and maintained a detectable level (100.00 +/- 0.00) up to 21 day post partum (DPP). The IgG was the predominant immunoglobulin followed by IgA and IgM. Piglets born of vaccinat...
متن کاملImmunization of calves against enterotoxigenic colibacillosis by vaccinating dams with purified K99 antigen and whole cell bacterins.
Pregnant cattle were either vaccinated subcutaneously with (i) a suspension of purified Escherichia coli K99 pili, (ii) a Formalin-killed whole cell bacterin containing enterotoxigenic E. coli strain B44 (O9:K30;K99:H-), or (iii) a bacterin containing six different strains of bovine enterotoxigenic E. coli (multiple-strain bacterin), or were left as nonvaccinated controls. After birth, calves w...
متن کاملOral immunization against enterotoxigenic colibacillosis in weaned piglets by non-pathogenic Escherichia coli strain with K88 (F4) colonizing factors
Experiments were focused on the prevention of diarrhoea in weaned piglets by means of enterotoxigenic strains of Escherichia coli (ETEC) with colonizing factors K88 (F4). The process of immunization consisted of intramuscular administration of ETEC strain bacterin one day prior to weaning and oral administration of a live culture of non-pathogenic E. coli strain containing colonizing factors (O...
متن کاملExperimental neonatal colibacillosis in cows: immunoglobin classes involved in protection.
Pregnant cows were vaccinated with one of four vaccine preparations to induce passive immunity in their offspring against a homologous oral challenge with Escherichia coli strain B-44. Quantitative assays of specific antibody in colostral whey from both immunized and nonimmunized dams revealed that immunoglobulin G, immunoglobulin A (IgA), and immunoglobulin M (IgM) with anti-O (somatic) activi...
