Catecholamines during development of the parasitic nematode, Haemonchus contortus.
1. Catecholamines from infective larvae of Haemonchus contortus were extracted, separated on HPLC, and measured on an electrochemical detector. DOMA 18 ng/100,000 larvae: NE 6 ng: E 1 ng: DA 1 ng 2. Levels of norepinephrine decreased below detection level rapidly after gassing with CO2. 3. Levels of 3,4-dihydroxymandelic acid (DOMA), a metabolite of norepinephrine, increased when exsheathment took place in tap water rather than buffer.
