Moxidectin is an anthelmintic drug used in animals to prevent or control parasitic worms , such as heartworm and intestinal worms, in dogs, cats, horses, cattle, sheep and wombats. [4] Moxidectin kills some of the most common internal and external parasites by selectively binding to a parasite's glutamate-gated chloride ion channels.
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
In the human host, Loa loa larvae migrate to the subcutaneous tissue, where they mature into adult worms in approximately one year, but sometimes up to four years. Adult worms migrate in the subcutaneous tissues at a speed of less than 1 cm/min, mating and producing more microfilariae. The adult worms can live up to 17 years in the human host. [5]

[ 24 ] [ 25 ] [ 26 ] Further testing confirmed aminorex in human and canine urine, meaning that both humans and dogs also metabolize levamisole into aminorex ...
