Pyruvate kinase in Haemonchus contortus larvae
Comparative Biochemistry and Physiology, 1968Abstract 1. 1. By using an indirect assay procedure, pyruvate kinase was detected in Haemonchus contortus extracts. 2. 2. The level of activity detected in H. contortus was considerably lower than that detected in rat liver and the significance of these findings in relation to fermentative metabolism in parasites is discussed.

Carbohydrate epitopes on Haemonchus contortus antigens
Parasitology Research, 1996Extracts of infective larvae and adults of the trichostrongylid Haemonchus contortus were studied for the presence of carbohydrate moieties. Several different lectin-binding sites were demonstrated in both stages using a panel of nine lectins. The carbohydrate specificity of the lectins used strongly suggests that alpha-D-mannose, alpha-D-glucose, and ...

The developmental lipidome of Haemonchus contortus
International Journal for Parasitology, 2018Lipids play crucial roles in the biology of organisms, particularly relating to cellular membranes, energy storage, and intra- or inter-cellular signalling. Despite the recent expansion of the lipidomics field, very little is known about the biology of lipids in metzoan pathogens, and, to date, there has been no global lipidomic study of a parasitic ...

Extracellular Matrix Degradation by Haemonchus contortus
The Journal of Parasitology, 1996To better understand the in vivo function of secreted cysteine proteases of Haemonchus contortus, the ability of live parasites to degrade connective tissue was investigated using [3H]proline-labeled extracellular matrix produced by smooth-muscle cells (R22).

Haemonchus contortus microtubules are cold resistant
Molecular and Biochemical Parasitology, 2014Haemonchus contortus is an important nematode of livestock that is present in most parts of the world. The life cycle comprises free living stages (egg, L1, L2 and L3 larvae), and parasitic stages (L4, adult and egg) in a ruminant. Microtubules are filamentous structures which are made from polymerization of α- and β-tubulin. In vitro polymerization of

Haemonchus contortus transthyretin domain-containing protein (HcTTR) with 136 amino acids belongs to a transthyretin-like (TTL) family member. In our previous study, it was reported that HcTTR was a novel antagonist of the goat cytokine Interleukin 4 (IL-4), and was involved in the regulation of host immune responses, implying that it might be applied ...

Levamisole binding sites in Haemonchus contortus
International Journal for Parasitology, 1998Larval and adult extracts from isolates of Haemonchus contortus were assayed for specific [3H]levamisole binding activity. All of the tissue preparations displayed [3H]levamisole binding sites. The sensitive isolate SE and resistant isolate RJ showed no differences in larval and adult binding data. Larval SE extracts had higher receptor density (Bmax =

International Journal for Parasitology, 1981
Abstract There were distinct ecotypie differences in the ability to develop to third stage larvae at a constant 11 or 13°C for two weeks. H. conforms cayugensis could develop at both 11 and 13°C; H. contortus from Louisiana could develop at 13°C but not 11°C and H. placei could not complete development at either temperature.
