Abstract

Pulmonary and serum antibody responses were evaluated in eight calves vaccinated [four intrapulmonary-right diaphragmatic lobe (IP) and four subcutaneous (SC)] with Pasteurella haemolytica Al (Ph-1) impregnated agar beads and eight respective sham-vaccinated calves. Experimental and sham groups were challenged in both diaphragmatic lobes with Ph-1 34-37 d after vaccination (DAV) and necropsied 6 d after challenge (DAC; 40-43 DAV). IgG antibodies contained in fluids from the diaphragmatic lobes of vaccinated calves had different patterns of antigen specificity compared with IgG antibodies in analogous sera. Using ELISA, anti-Ph-1 IgA and IgG antibody concentrations were significantly higher (P < 0.05) in lung lavage fluids from the IP group before and after challenge compared to the SC and sham groups. The IP and SC groups developed IgA, IgG and IgM antibody titers in nonvaccinated lung lobes after vaccination and challenge. The IP and SC groups exhibited significantly (P < 0.05) smaller pulmonary lesions than the sham groups and pulmonary IgG and IgA antibodies were associated with increased protection.
