Despite the efforts of thousands of parasitologists, remarkably few 
parasites appear to have been driven to extinction. Job Security Rules OK!

In the northern part of NSW, Australia, 2 formerly pathogenic nematode 
parasites of sheep, Oesophagostomum columbianum and Dictyocaulus filaria 
appear to have been eradicated by control programs largely directed against 
other species, as well as partial eradication, on a farm-by-farm basis, of 
the dreaded Haemonchus contortus, using closantel. See Barger, Hall & Dash 
(1991) Australian Veterinary Journal 68:347-348.
