Immunoglobulins and their relative neutralizing efficiency in cattle immunized with infectious bovine rhinotracheitis ? Parainfluenza-3 (IBR-PI-3) virus vaccine

Abstract: The localization of anti-IBR and anti-PI-3 activity in the serum and nasal secretory immunoglobulins following intranasal immunization of cattle with a mixed vaccine (IBR-PI-3, MLV, TCO) was studied and was found to reside in the nasal secretory IgA, serum IgM and IgG fractions. The computation of their relative virus neutralizing efficiencies from kinetic data revealed their order of neutralizing efficiencies to be IgM greater than IgA greather than IgG.

“…The results reported here are in keeping with earlier findings (6) and with general views on the character of the course of the immune response. The present evidence, including comparison of the dynamics of antiviral antibody production in infected and vaccinated calves, indicates further possible applications of new immunodiagnostic methods.…”

“…The study is also consistent with the study conducted thirty years ago by Morgan et al (1981) where IgA was shown to be the major immunoglobulin in upper respiratory tract secretions of ruminants as it is in other species studied (Morgan et al, 1981). In addition, several studies conducted on neutralizing activity in the NS of cattle following either natural or intranasal exposure to live PI-3 virus or mixed live vaccine comprising PI-3 and IBR viruses is almost exclusively associated with IgA (Morein, 1970 andMukkur et al, 1975).…”
