Question:  Elaeophora schneideri is hosted in what deer that is named for its large ears?

Context paragraphs:
Fennec fox: The fennec fox or fennec ("Vulpes zerda") is a small nocturnal fox found in the Sahara of North Africa.  Its most distinctive feature is its unusually large ears, which also serve to dissipate heat.  Its name comes from the Arabic word فنك ("fanak"), which means "fox", and the species name "zerda" comes from the Greek word "xeros" which means dry, referring to the fox's habitat.  The fennec is the smallest species of canid.  Its coat, ears, and kidney functions have adapted to high-temperature, low-water, desert environments.  In addition, its hearing is sensitive enough to hear prey moving underground.  It mainly eats insects, small mammals, and birds.

Papillon (dog): The Papillon (] , ""butterfly[-eared]""), also called the Continental Toy Spaniel, is a breed of dog of the Spaniel type.  One of the oldest of the toy spaniels, it derives its name from its characteristic butterfly-like look of the long and fringed hair on the ears, the French word for "butterfly" being "papillon".  A Papillon with dropped ears is called a Phalène (French for "moth").  The small head is slightly rounded between the ears with a well defined stop.  The muzzle is somewhat short, thin tapering to the nose.  The dark, medium-sized, round eyes have thin black rims, often extending at the junction of the eyelids towards the ears.  The large ears can either be erect or dropped with rounded tips.  The teeth meet in a scissors bite.  The long tail is set high carried over the body, and covered with long, fine hair.  Dewclaws are sometimes removed.  The straight, long, fine, single coat has extra frill on the chest, ears, back of the legs and the tail.  Coat color is white with patches of any color.  A mask of a color other than white covers both ears and eyes from back to front.

Pack rat: A pack rat or packrat, also called a woodrat, can be any of the species in the rodent genus "Neotoma".  Pack rats have a rat-like appearance with long tails, large ears and large black eyes.  Compared to deer mice, harvest mice and grasshopper mice, pack rats are noticeably larger and are usually somewhat larger than cotton rats.

Panotti: The Panotti (also Panotii and Panotioi, from the Greek words πᾶν and οὖς for "all ears") were a mythical race of people, described as possessing large ears that covered their entire bodies.

Permyak Salty Ears: Permyak Salty Ears (Russian: Пермяк солёные уши ) is a 2006 urban sculpture by Rustam Ismagilov in the city of Perm, Russia.  The sculpture consists of two parts - the figure of the photographer and a round frame with large ears, in which those who wish to pose for a photograph can put their faces.

Elaeophora: Elaeophora is a genus of parasitic nematodes which live attached to the interior surfaces of major arteries, veins and/or heart chambers in various large mammal hosts.  Infestation with "Elaeophora" species is referred to as elaeophorosis.  The species of "Elaeophora" have been found in Africa, Asia, Europe, and North America.  Despite the fact that they produce aneurysms in the arteries and heart of their hosts which measure up to 2 cm in diameter, overt clinical symptoms of infestation are seldom reported, with the notable exception of "E. schneideri" infestation in sheep, elk, and moose.

Mule deer: The mule deer ("Odocoileus hemionus") is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule.  There are believed to be several subspecies, including the black-tailed deer.

Macrotus: Macrotus is a genus of bats in the Neotropical family Phyllostomidae.  This genus contains two species, "Macrotus californicus" commonly known as California Leaf-nosed Bat and "Macrotus waterhousii" commonly known as Mexican or Waterhouse's Leaf-nosed Bat.  The range of this family includes the warmer parts of the southwestern United States, Mexico, Central and South America, and the Bahama Islands.  Characteristic for the genus are large ears and the name giving triangular skin flap above the nose, the "leaf".  The California Leaf-nosed Bat inhabits the arid deserts of the southwestern United States as far north as Nevada, south to Baja California and Sonora, Mexico.  The California Leaf-nosed Bat is of medium size, with a total length between 9 and 11 cm Its most distinctive features are the large ears, connected across the forehead.  The body is pale grayish brown dorsally with whitish under parts.  The pelage (fur) on the body is silky, the hairs on the back about 8 mm, on the front about 6 mm long.  The posterior base of the ears are covered with hair of a woolly texture while the interior surface and most of the anterior border shows scattered long hairs.  The flight membranes are thin and delicate; the wings are broad and the tail is slightly shorter that the long hind limbs and extends several millimeters beyond the uropatagium (see Bat).  "Macrotus waterhousii" is also a big eared Bat which has ranges from Sonora to Hidalgo Mexico, south to Guatemala and the Greater Antilles (excluding Puerto Rico) and Bahamas.  This species roosts primarily in caves, but also in mines and buildings.  This species is also insectivorous (see insectivore), primarily consuming insects of the order Lepidoptera and Orthoptera.  The mating and parturition times of M. "waterhousii" vary from island to island with 4–5 months gestation.

Elaeophora schneideri: Elaeophora schneideri (arterial worm; cause of elaeophorosis, aka "filarial dermatitis" or "sorehead" in sheep; or "clear-eyed" blindness in elk) is a nematode which infests several mammalian hosts in North America.  It is transmitted by horse-flies.  Infection in the normal definitive hosts, Mule deer or Black-tailed deer, seldom produces clinical symptoms.  In other hosts, such as sheep, elk, moose, and goats, infection with "E. schneideri" leads to elaeophorosis.  Symptoms of elaeophorosis include necrosis of the muzzle, ears, and optic nerves; lack of coordination (ataxia); facial or lower limb dermatitis; horn deformities; blindness; and death.

Indo-Brazilian cattle: Indo-Brazilian cattle are a Zebu beef breed developed in Brazil from Gir, Kankrej and Ongole Cattle brought from India.  While this is nearly the same mixture which produced the American Brahman, the two breeds differ in appearance, with the Indo-Brazilian having much longer ears which hang down lower, like the Nelore.  Indo-Brazilian cattle have good heat and parasite resistance and thrive in the tropics.  They are white to dark grey in colour with short horns and very large ears.  They have the typical Zebu shoulder hump.
