Haemonchus contortus: Enzymes. II. Fructose diphosphate aldolase

Experimental Parasitology, 1972
Abstract Soluble extracts were prepared from adult male and female Haemonchus contortus by differential centrifugation. This extract was fractionated DEAE-cellulose, CM-cellulose, and by sucrose-density-gradient centrifugation. A 20-fold purification from the crude soluble extract was achieved resulting in a preparation having an activity of 5.46 ...

Hybridization of Australian Haemonchus placei (place, 1893), Haemonchus contortus cayugensis (Das & Whitlock, 1960) and Haemonchus contortus (Rudolphi, 1803) from Louisiana

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.

Variability in Haemonchus contortus larvae

2021
Coprological analysis allow the identification of parasitism of ruminants by trychostrongylid but not to species level. In order to know species implicated eggs must be cultured and larvae must develop on coproculture and mature to infective stage of L3.
