| A panel of 13 monoclonal antibodies (MAbs) that react against outer membrane proteins of Salmonella Enteritidis was obtained. Two MAbs were classified as IgM, six were IgG2a, three were IgG3 and one was of the IgG2b isotype. The reactivity of the MAbs against different serovars of Salmonella enterica and other bacteria was investigated using an indirect ELISA. Five MAbs reacted only against Salmonella Enteritidis. Two MAbs presented crossed reactions with thermo-extracted antigens of Klebsiella pneumoniae, Citrobacter freundii and Enterobacter aerogenes. MAb 424H presented wide spectrum of reactivity, detecting antigens of Salmonella belonging to serogroups B, C, D, E and G. The detection limit of different serovars of Salmonella in a indirect ELISA with... |

| Two hybridomas secreting monoclonal antibodies (MAbs) that react with a lipoprotein (LipL32) of the outer membrane of pathogenic Leptospira were obtained. For hybridoma production, spleen cells from BALB/c mice imunized with recombinant LipL32 (rLipL32) were fused to SP2/O-Ag14 cells, selected in HAT medium and screened in an indirect ELISA. One MAb produced was of the IgG2b isotype and the other was an IgM. MAbs specificity was confirmed by indirect ELISA and immunoblotting using purified rLipL32 and whole-cell antigen preparations from Escherichia coli (E. coli) expressing LipL32 and from pathogenic and non-pathogenic serovars. Both Mabs reacted with most of the pathogenic serovars tested and none reacted with non-pathogenic Leptospira. The MAbs... |
