Lectin, hemolysin and protease inhibitors in seed fractions with ovicidal activity against Haemonchus contortus Lectina, hemolisina e inibidores de protease em frações de sementes com atividade ovicida contra Haemonchus contortus
Bioactive molecules of plant species are promising alternatives for the chemical control of gastrointestinal nematodes in ruminants. Extracts of native and exotic seed species from Brazil’s semi-arid region were tested in vitro in an egg hatch assay and the bioactivity of their proteins was investigated. Each seed species was subjected to three extractions with three types of solvents. All the ...
متن کاملImmunoprotection 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 کاملOvicidal and larvicidal activity of Cassia alata leaf acetone extract and fractions on Haemonchus contortus: in vitro studies.
CONTEXT The failure of modern anthelmintics to control nematode parasites of sheep and goats is a reality on many farms in the tropical/subtropical regions of the world. This necessitates chemotherapeutic control alternatives and plant secondary metabolite with activity is one of those potential solutions. OBJECTIVE This study was design to evaluate the efficacy of solvent: solvent fractions ...
متن کاملIn Vitro Ovicidal and Larvicidal Activities of Stem Bark of Terminalia glaucescens (Combretaceae) against Haemonchus contortus
Objectives: To evaluate the in vitro activity of aqueous and methanolic extracts of stem bark of Terminalia glaucescens on the eggs and larval stages of Haemonchus contortus of sheep. Methods: The eggs were exposed for 24 hours in five different concentrations (625, 1250, 2500, 3750 and 5000 μg/ml) of methanol, hot water (decoction) and cold water extracts at room temperature (25 ̊C). Distilled ...
متن کاملAnthelmintic activity of Cymbopogon citratus against Haemonchus contortus.
Parasitic nematodes are of major economic importance in livestock. An alternative for the control of parasites is phytotherapy. This study evaluated the efficacy of Cymbopogon citratus decoction (CcD), C. citratus essential oil (CcEo) and citral against Haemonchus contortus using in vitro egg hatch test (EHT) and larval development test (LDT) and an in vivo test using a Meriones unguiculatus (g...
