Synergism between ivermectin and the tyrosine kinase/P-glycoprotein inhibitor crizotinib against Haemonchus contortus larvae in vitro [PDF]

, 2016
Anthelmintic resistance is a major problem in parasitic nematodes of livestock worldwide. One means to counter resistance is to use synergists that specifically inhibit resistance mechanisms in order to restore the toxicity, and hence preserve the ...

Ecology of Haemonchus contortus eggs and larvae on a pasture in Chechen Republic

Российский паразитологический журнал, 2016
Features of ecology and biology of Haemonchus contortus eggs and larvae on a pasture in Chechen Republic are investigated. H. contortus larvae reach infective stage in spring and autumn during 7–13 days and in summer during 7–9 days.

Possible mechanisms of host resistance to Haemonchus contortus infection in sheep breeds native to the Canary Islands [PDF]

, 2016
Haemonchus contortus appears to be the most economically important helminth parasite for small ruminant production in many regions of the world. The two sheep breeds native to the Canary Islands display distinctly different resistant phenotypes under ...

The genome and developmental transcriptome of the strongylid nematode Haemonchus contortus [PDF]

, 2013
Background: The barber's pole worm, Haemonchus contortus, is one of the most economically important parasites of small ruminants worldwide. Although this parasite can be controlled using anthelmintic drugs, resistance against most drugs in common use has

Comparison of Metabolomic Signatures Between Low and Heavy Parasite Burden of Haemonchus contortus in Meat Goats Fed with Cynodon dactylon (Bermudagrass) and Crotalaria juncea L. (Sunn Hemp)

Metabolites
Background/Objectives: Animal health remains a critical issue that directly impacts economic sustainability through animal welfare and production. In small ruminants, the gastrointestinal parasite Haemonchus contortus can lead to anemia and possibly ...

In vitro studies of the anthelmintic activity of Picrolemma sprucei Hook. f. (Simaroubaceae) Estudos in vitro da atividade anti-helmíntica de Picrolemma sprucei Hook. f. (Simaroubaceae)

Acta Amazonica, 2006
1300 ppm (1.3 g / L), water and ethanol extracts prepared from stems or roots of Picrolemma sprucei Hook. f. were lethal (85-90 % mortality) in vitro to Haemonchus contortus (Barber Pole Worm) larvae, a gastrointestinal nematode parasite found in ...

In vitro effects of three woody plant and sainfoin extracts on two parasitic stage of 3 parasitic nematode species [PDF]

, 2004
Most studies on the effects of tanniferous plants on nematodes have examined forages but have neglected the woody plants. Therefore, in vitro effects of extracts from 3 woody plants (Rubus fructicosus, Quercus robur, Corylus avellana) have been tested on
