Haemophilus pleuropneumoniae serotypes--cross protection experiments 总被引:19,自引:0,他引:19
R Nielsen 《Nordisk veterinaermedicin》1984,36(7-8):221-234
Pigs vaccinated with a killed 6-hour culture of Haemophilus pleuropneumoniae serotype 2 with Freund's incomplete adjuvant were not protected against challenge with serotypes 1, 5, 6 or 8. Equivalent results were obtained when pigs were vaccinated with serotypes 4 or 5 and challenged with serotype 2. In earlier studies of immunity induced by intranasal immunization with live H. pleuropneumoniae organisms, it was clearly shown that intranasal inoculation with one serotype of H. pleuropneumoniae would induce a strong immunity to both homologous and heterologous serotypes (Nielsen 1979). The present study has shown that cross immunity is not obtained with parenteral immunization. The results strongly suggest that the immune response of the pig to parenteral vaccination is different from the response seen after natural infection, and indicate that an important part of the defence mechanism against H. pleuropneumoniae infection is a local immune-barrier which is effective in preventing the bacterium from penetrating the mucosa. In earlier vaccination experiments 90 per cent of vaccinates were protected against homologous challenge (Nielsen 1976). In the present work a vaccine containing serotypes 1 through 6 was fully protective against serotypes 2 and 3 and also against serotype 8, which shares antigenic determinants with serotypes 3 and 6. These results indicate that the protection obtained by parenteral immunization is serotype-specific. Vaccines must therefore contain the serotypes existing in the swine population. 相似文献
