screening of cathepsin L1/cathepsin L2 mimotopes and use of an M13 phage random 12-mers peptide library to evaluate their immunogenicity in sheep. Immunization of sheep with clones showing positive reactivity to rabbit cathepsin L1/L2 antiserum results in decrease in worm burdens after challenge. A significant reduction in worm size and burden is observed for those sheep immunized with clone 1. Animals receiving clone 20, show a significant reduction in egg output. Immunization induces a reduction of egg viability ranging from 58% to 82%. Vaccinated animals produce clone-specific antibodies which are boosted after challenge with metacercariae of Fasciola hepatica |

a monoclonal antibody (MoAb) against recombinant Fasciola gigantica cathepsin L1H (rFgCatL1H) is produced by hybridoma technique using spleen cells from BALB/c mice immunized with recombinant proFgCatL1H (rproFgCatL1H). This MoAb is an immunoglobulin (Ig)G1 with kappa light chain isotype. The MoAb reacts specifically with rproFgCatL1H, the native FgCatL1H at a molecular weight (MW) 38-48 kDa in the extract of whole body (WB) of metacercariae and newly excysted juvenile (NEJ) and cross-reacted with rFgCatL1 and native FgCatLs at MW 25 to 28 kDa in WB of 2- and 4-week-old juveniles, adult, and adult excretory-secretory (ES) fractions by immunoblotting and indirect ELISA. It does not cross-react with antigens in WB fractions from other parasites. FgCatL1H and its MoAb may be used for immunodiagnosis of both early and late fasciolosis in ruminants and humans |

analysis of the diagnostic values of the three different clades of cathepsin Ls, FhCL1, FhCL2, and FhCL5, from adult flukes in an ELISA, test of sera from sheep and cattle naturally infected with Fasciola hepatica, of cross-reactive antibodies, overview. For sheep sera, the sensitivity is 100% for the three rFhpCLs, while for cattle sera, the highest sensitivity is obtained using rFhpCL2 (97%), being equal for both rFhpCL1 and rFhpCL5 (87.9%), after adjusting cut-offs for maximum specificity |

recombinant proFgCatL1H protein expressed from Pichia pastoris is mixed with Freund's adjuvants and used to subcutaneously immunize mice, the mice are then challenged with metacercariae of Fasciola gigantica. The percentage of worm protection in the rproFgCatL1H-vaccinated mice compared to the non-immunized and adjuvant control mice are approximately 62.7% and 66.1%, respectively. Anti-rproFgCatL1H antisera collected from vaccinated mice react specifically with rproFgCatL1H and other cathepsin L isoforms of Fasciola gigantica, but the antibodies do not crossreact with antigens from other trematode and nematode parasites, including Eurytrema pancreaticum, Opisthorchis viverrini, Fischoederius cobboldi, Cotylophoron cotylophorum, Gigantocotyle explanatum, Paramphistomum cervi, and Setarialabiato papillosa |
