The potential of controlling gastrointestinal parasitic infections in tropical small ruminants using plants high in tannins or extracts from them
A series of previous studies with quebracho tannin (QT) had shown that the tannin was effective at reducing the worm burden of temperate sheep infected with Haemonchus and Trichostrongylus. The potential of using tanniniferous browse plants available in the tropics as a means to reduce or control nematode infections of small ruminants was, therefore, investigated. Leaves of different browse tre...
متن کاملIn vitro anthelmintic activity of Tunisian fabacae (Hedysarum coronarium L., ecotype Bikra 21) against Haemonchus contortus
The use of bioactive tanniniferous plants was suggested as an alternative to control gastrointestinal nematodes (GIN) infections in small ruminants. This study aimed to evaluate the anthelmintic effect of acetonic extract of Hedysarum coronarium (Ecotype Bikra 21, sulla) as fresh or dried biomass (hay) in the infective larvae (L3) of Haemonchus contortus. The larval exsheathment assay (LEA) was...
متن کاملAdvances in the diagnosis of key gastrointestinal nematode infections of livestock, with an emphasis on small ruminants.
Parasitic nematodes (roundworms) of livestock have major economic impact globally. In spite of the diseases caused by these nematodes and some advances in the design of new therapeutic agents (anthelmintics) and attempts to develop vaccines against some of them, there has been limited progress in the establishment of practical diagnostic techniques. The specific and sensitive diagnosis of gastr...
متن کاملIn vitro anthelmintic activity of some Mediterranean plants against Haemonchus contortus infective stage
The use of bioactive tanniniferous plants seems a promising alternative to control infections parasitic nematodes of the gastro intestinal tract in small ruminants. Both in vitro and in vivo studies, have confirmed the anthelmintic properties of several forage legumes, or tropical and browse plants. The aim of the present study was to evaluate the in vitro anthelmintic (AH) effect of 3 Tunisian...
