Immunoprotection in goats against Haemonchus contortus after immunization with cysteine protease enriched protein fractions.
Haemonchus cysteine proteases, because of their apparent critical function in worm physiology, are considered important candidates in the immunological control of haemonchosis in sheep. Only limited information is, however, available on the immunoprotective properties of these molecules in goats. In the present study cysteine proteases of Haemonchus contortus adult worms isolated from a goat st...
متن کاملGenetic variability in cysteine protease genes of Haemonchus contortus.
To increase the existent genetic variability in cysteine proteases, a polymorphism study was performed in Haemonchus contortus by comparing 2 different strains of the parasite: North American (NA) and Spanish (SP) strains. For this purpose, the polymorphism of 5 previously reported genes (AC-1, AC-3, AC-4, AC-5 and GCP-7) were analysed by PCR-SSCP and sequencing procedures. Based on the SSCP re...
متن کاملImmunoprotection in sheep against Haemonchus contortus using its thiol-purified excretory/secretory proteins
Excretory/Secretory antigen was prepared by culturing live adult worms of Haemonchus contortus in RPMI 1640 medium at a concentration of 50 worms per mL in a culture-flask at 37 ˚C for 24 hr and the culture supernatant was used as antigen. The E/S antigen was purified by thiol-sepharose affinity chromatography. On western blot analysis, it was demonstrated that thiol-purified antigen showed a s...
متن کاملIn vitro anthelmintic effects of Spigelia anthelmia protein fractions against Haemonchus contortus
Gastrointestinal nematodes are a significant concern for animal health and well-being, and anthelmintic treatment is mainly performed through the use of chemical products. However, bioactive compounds produced by plants have shown promise for development as novel anthelmintics. The aim of this study is to assess the anthelmintic activity of protein fractions from Spigelia anthelmia on the gastr...
