Immunogenicity and Efficacy of a Rough Brucella suisVaccine Delivered Orally or Parenterally to Feral Swine

Abstract: Brucella suis strain 353-1 is a stable vaccine strain that is clinically safe, does not cause positive serologic responses on conventional brucellosis surveillance tests, and induces humoral and cellular immunity in swine after vaccination. In this study, we evaluated tissue clearance and immunologic responses after oral or parenteral vaccination of feral swine with 1.9 x 10 10 colony-forming units (CFU) of strain 353-1, and compared efficacy of vaccination and control treatments in protecting against infectio… Show more

“…We observed no renal lesions, aside from multifocal hemorrhages, in porcine fetuses infected with B. suis bv 2, although suppurative or lymphocytic interstitial nephritis has been reported in bovine fetuses infected with B. abortus or the B. abortus RB51 vaccine, respectively, 13,38,48 as well as in safety and efficacy vaccination studies using a natural rough mutant of B. suis (strain 353-1) in 6-wk-old pigs. 34,43 Experimental B. melitensis infection in caprine fetuses can cause necrosis of glomeruli and renal hemorrhages, and Brucella immunoreaction has been observed in glomeruli, tubules, and interstitium of both ovine and caprine fetuses. 24,28 We observed interstitial hemorrhages in aborted porcine fetuses, but not necrosis.…”
