Question: 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?
Context: Dirofilaria repens is a filarial nematode that affects dogs and other carnivores such as cats, wolves, coyotes, foxes, muskrats, and sea lions.  It is transmitted by mosquitoes.  Although humans may become infected as aberrant hosts, the worms fail to reach adulthood while infecting a human body. Sea lions are sea mammals characterized by external ear flaps, long foreflippers, the ability to walk on all fours, and short, thick hair, big chest and belly.  Together with the fur seals, they comprise the family Otariidae, eared seals, which contains six extant and one extinct species (the Japanese sea lion) in five genera.  Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean.  They have an average lifespan of 20–30 years.  A male California sea lion weighs on average about 300 kg and is about 8 ft long, while the female sea lion weighs 100 kg and is 6 ft long.  The largest sea lion is Steller's sea lion, which can weigh 1000 kg and grow to a length of 10 ft .  Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 15 – ) at a single feeding. The California sea lion ("Zalophus californianus") is a coastal eared seal native to western North America.  It is one of six species of sea lion.  Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California.  Sea lions are sexually dimorphic; males are larger than females, and have a thicker neck and protruding crest.  They mainly haul-out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and wharves.  Sea lions feed on a number of species of fish and squid, and are preyed on by orcas and white sharks. Loa loa is the filarial nematode (roundworm) species that causes "Loa loa" filariasis.  "Loa loa" actually means "worm worm" but is commonly known as the "eye worm" as it localizes to the conjunctiva of the eye.  Loa Loa is commonly found in Africa.  It mainly inhabits rain forests in West Africa and has native origins in Ethiopia. Feeding Sea Lions is short silent film featuring Paul Boyton feeding sea lions at his Sea Lion Park at Coney Island.  Boyton is shown feeding the trained sea lions, twelve in number.  The sea lions follow Boyton up the steps of the pool and then follow him back into the water.  One of them steals food out of the basket.  The film was made by Lubin Studios on March 10, 1900. Dirofilaria immitis, the heartworm or dog heartworm, is a parasitic roundworm that is spread from host to host through the bites of mosquitoes.  The heartworm is a type of filarial worm, a small thread-like worm, that causes filariasis.  The definitive host is the dog, but it can also infect cats, wolves, coyotes, jackals, foxes, and other animals, such as ferrets, bears, sea lions and even, under very rare circumstances, humans.  The parasite is commonly called "heartworm"; however, adults often reside in the pulmonary arterial system (lung arteries), as well as the heart, and a major effect on the health for the animal is a manifestation of damage to the lung vessels and tissues.  Occasionally, adult heartworms migrate to the right heart and even the great veins in heavy infections.  Heartworm infection may result in serious disease for the host, with death typically as the result of congestive heart failure. 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. The Olivarez College Sea Lions is the collegiate men's varsity basketball team of Olivarez College - Parañaque.  It plays in the NCR-UCL Athletic Association (NCR-UCLAA) in the Philippines.  The collegiate women's varsity basketball team is called the "Lady Sea Lions", while the high school varsity basketball team is called the "Junior Sea Lions". The Point Loma Nazarene University Sea Lions (also PLNU Sea Lions) are the 11 varsity athletic teams that represent Point Loma Nazarene University, located in San Diego, California, in NCAA Division II intercollegiate sports.  Point Loma officially became an active member in the NCAA during the Summer of 2014, which signified the conclusion of their three-year transition process from the NAIA to NCAA Division II.  The Sea Lions compete as members of the Pacific West Conference for all sports.  PLNU was previously a member of the NAIA's Golden State Athletic Conference (GSAC). Capillaria feliscati (also known as Pearsonema feliscati, the cat bladder worm is a worm that affects cats, and seldom dogs.  Its main final hosts are wild carnivores (foxes, wolves, coyotes, hedgehogs, etc.).  It is a urinary tract nematode, though its occurrence is rare.  "C. feliscati" are small, delicate, yellowish, thread-like worms.  Adults are approximately between 16 and in length.
