The use of an enzyme-linked immunosorbent assay (ELISA) as a means of detecting dermone-crotoxin-producing strains of Pasteurella multocida was investigated. The assay was evaluated as a means to identify toxigenic P. multocida isolates recovered from nasal secretions of swine with atrophic rhinitis. The sensitivity and specificity of the ELISA for detecting dermonecrotoxin-producing P. multocida strains were compared to those of mouse-inoculation and cytotoxicity assays. The ELISA was highly sensitive and more specific than animal inoculation or tissue culture assay and is thus a more effective method for screening swine herds for the presence of toxigenic strains of P. multocida. The ELISA is a rapid, effective, economical way to identify toxigenic P. multocida isolates.

Background and Aim: The current vaccination for peste des petits ruminants virus (PPRV) is stalled by myriad challenges and continuous endemicity of pneumonia due to fulminant bacterial complication in goats. The present study evaluated the protective effect of intranasal PPRV linage 1 and bacterine vaccinations. Materials and Methods: Twelve West African Dwarf (WAD) goats aged 6 months were randomly grouped and vaccinated within 2 weeks using a combination of PPRV lineage 1 vaccine (Nig/75), and bacterin from Mannheimia haemolytica (Mh) or Pasteurella multocida intranasally. The goats were observed for 3 weeks post-vaccination before comingled with a known infected WAD goat with apparent clinical signs of peste des petits ruminants and further observed clinically for 5 weeks post-infection (PI). Blood samples were taken for hematology while sera were assayed for antioxidants (glutathione peroxidase, glutathione transferase, and superoxide dismutase) activities and pro-oxidants (malondialdehyde content, reduced glutathione, hydrogen peroxide generation, and myeloperoxidase) using spectrophotometric methods. Data were subjected to parametric statistics at α=0.05 using GraphPad Prism version 21. Results: Clinically, there were pyrexia, oculonasal discharge, diarrhea, anemia, leukopenia, and increased pro-oxidants in the unvaccinated goats, while moderate neutrophilia and leukocytosis were observed in PPRV and bacterin vaccinated goats. Two unvaccinated goats were weak and euthanized at 13 and 28 days PI. The goats vaccinated with PPRV and Mh showed better response clinically and biochemically. Conclusion: The mucosal vaccination of goats with PPRV vaccine and bacterine will protect against exposure and culminate in the development of protective mucosal, humoral, and cell-mediated immune responses. This vaccination strategy will provide framework needed in the prevention and control of endemic caprine pneumonia in Nigeria.

Capsular type A and D strains of Pasteurella multocida are the main epidemic serogroups in pigs in China. In this study, we preliminarily evaluated the immune protective efficacy of the two traditional vaccines, an inactivated C44-1 aluminum-hydroxide-gel-adjuvanted (Alh–C44-1) vaccine and a live EO630 vaccine, against currently circulating strains of P. multocida in a mouse model. Mice immunized twice with conventional vaccines generated higher antibody titers, and significantly higher levels of IgG were observed in the mice inoculated with the inactivated Alh–C44-1 vaccine on day 35 (p < 0.05) than those with the live EO630 vaccine. The mice immune protection test showed that the vaccination groups had a 57% or 71% protection effect against the serogroup B strain, but had no protective effect against epidemic strains. In conclusion, our study found that the widely used traditional P. multocida vaccines in China provide good protection against homologous strains, but could not provide cross-protection against heterologous strains in a mouse model.
