The developmental lipidome of Haemonchus contortus

International Journal for Parasitology, 2018
Lipids 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 ...

Resistance of Haemonchus contortus to thiophanate

Research in Veterinary Science, 1980
The occurrence of a field strain of Haemonchus contortus which was resistant to thiophanate and susceptible to thiabendazole and levamisole is reported. The LD95 of thiophanate for the strain was found to be 156.1 mg/kg and its resistance factor was 6.7.

Pyruvate kinase in Haemonchus contortus larvae

Comparative Biochemistry and Physiology, 1968
Abstract 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.

Development and Survival of Haemonchus contortus on Pasture

American Journal of Veterinary Research, 1974
SUMMARY A study was made of the development and the survival of Haemonchus contortus eggs and larvae on a bluegrass pasture at Urbana, IL, during 1967–1969. A total of 296 experiments was done. In 148, unembryonated eggs in fresh sheep fecal pellets were placed on the pasture, and vegetation, pellets, and soil were examined periodically for infective ...

Inheritance of Cambendazole Resistance in Haemonchus contortus

American Journal of Veterinary Research, 1981
SUMMARY Fourth-molt larvae (M4) of cambendazole-resistant (CBZ-R) and cambendazole-susceptible (BPL) strains of Haemonchus contortus were recovered from donor lambs and inoculated orally into source lambs to effect mating in a 2nd lamb. Eggs produced by these parasitic matings were collected, cultured, and inoculated into lambs to compare the ...

Immunity to Haemonchus contortus and Vaccine Development

2016
Sheep are capable of developing protective immunity to Haemonchus contortus through repeated exposure to this parasite, although this immune protection is the result of a complex interaction among age, gender, physiological status, pregnancy, lactation, nutrition and innate and adaptive immunity in the host animal.

Haemonchus contortus: Cloning and characterization of serpin

Experimental Parasitology, 2010
The serpin gene of Haemonchus contortus (hc-serpin) was cloned and characterized in this study. Specific primers for rapid amplification cDNA ends (RACE) were designed based on the expression sequence tag (EST, BM173953) to amplify the 3'- and 5'-ends of hc-serpin. The full length of the cDNA of this gene was obtained by overlapping the sequences of 3'-

Localisation of serotonin and dopamine in Haemonchus contortus

International Journal for Parasitology, 2011
Serotonin and dopamine play important roles in the biology of nematodes where they exert their effect on feeding, locomotion and reproductive behavior. Haemonchus contortus, a parasitic nematode which infects small ruminants, is responsible for considerable economic losses in agriculture.
