Abstract:
:Vibrio vulnificus is an oyster-associated bacterial pathogen that causes life-threatening fulminating septicemia and necrotizing wound infections in humans. The capsular polysaccharide of V. vulnificus (VvPS) is critical for virulence. Previously we showed that active immunization of mice with a VvPS-tetanus toxoid (VvPS-TTa) conjugate vaccine conferred significantly higher protection against subsequent lethal challenge than immunization with VvPS alone. In the current study, we examined the utility of immunoprophylaxis or immunotherapy with hyperimmune antisera elicited by VvPS-TTa and VvPS-TTb conjugate vaccines prepared by different synthetic schemes. First we demonstrated that the Ribi adjuvant significantly enhanced the murine antibody response (P < or = 0.02) to both conjugates. Subsequently, high-titered polyclonal antisera were raised to VvPS-TTa and VvPS-TTb conjugate vaccines by using Ribi adjuvant or Freund's adjuvants. Antisera were observed to have protective effects when administered before and after acute lethal infection. All animals receiving prophylactic antisera intraperitoneally 24 h before lethal challenge with homologous carbotype 1 were protected, while 73 to 100% of control mice succumbed. Immunotherapy was also effective, with survival rates of 60 to 73% seen among mice when antisera were administered 2 h after bacterial challenge, at a time when symptoms of infection were already apparent. The protective effect of capsular antiserum appeared to be serotype specific. Antisera to the, carbotype 1 VvPS-TTa vaccine did not confer cross-protection against lethal challenge with carbotype 2 V. vulnificus despite partial structural similarity and a weak serological cross-reaction between the two carbotypes. Immune globulins induced by a potential multivalent VvPS conjugate vaccine composed of clinically prevalent carbotypes may have utility in the management of V. vulnificus infections and deserve further evaluation.
