Which company markets Melarsomine as Immiticide in order to treat a small thread-like worm that causes filariasis in dogs, mainly, but also cats, ferrets, bears, sea lions, and coyotes?
Melarsomine Melarsomine (melaminylthioarsenate) is a trypanocidal agent. In the U.S., it is marketed under the trade names "Immiticide" (Merial) and "Diroban" (Zoetis), and is approved by the FDA's Center for Veterinary Medicine for the treatment of adult heartworm ("Dirofilaria immitis") infection in dogs. It is not approved for treatment in cats, or dogs in late-stage infection.
Envenomation Envenomation is the process by which venom is injected into some animal by the bite (or sting) of a venomous animal. Many kinds of animals, including mammals (e.g., the northern short-tailed shrew, "Blarina brevicauda"), reptiles (e.g., the king cobra), spiders (e.g., black widows), and insects (e.g., wasps, honey bees, ants and caterpillars), employ venom for hunting and for self-defense. Most venoms are administered by biting the skin of the victim, but some venoms are applied externally, especially to sensitive tissues such as those that surround the eyes. In some reptiles, such as the Gila monster, venom in the saliva enters prey through bites of grooved teeth, but many animals have specialized organs such as hollow teeth (fangs) and tubular stingers that penetrate the prey's skin after which muscles attached to the attacker's venom reservoir forcibly squirt venom deep within the victim's body tissue. Death may occur as a result of bites or stings. The rate of envenoming is described as the likelihood of venom successfully entering a system upon bite or sting.
