| Abstract: | L.P. MANSFIELD, E. BILLETT, E. OLSEN AND S.J. FORSYTHE. 1996. The lipopolysaccharide antigenicity of 22 Salmonella strains (representing nine serogroups) and four non-salmonellae Enterobacteriaceae to the Salmonella genus specific monoclonal antibody M105 was analysed. The monoclonal antibody M105 reacted with all 22 Salmonella strains. Probing SDS-PAGE separated LPS molecules with MAb M105 revealed that the antibody reacted with the core region of all Salmonella serovars. However, no reaction was obtained to the long-chain LPS of serovars O ( Salm. adelaide and Salm. ealing ), C1 ( Salm. infantis, Salm. livingstone and Salm. virchow ) or Salm. arizonae . It is plausible that the presence of a second core antigenic type results in the lack of reaction between long-chain LPS and the Salmonella genus specific monoclonal antibody M105. |
