text: A Handbook of Veterinary Parasitology was first published in 1978. Practitioners, teachers, and students of veterinary medicine and animal technicians will find this handbook extremely useful in their work. It provides a quick and easy reference for the identification and control of parasites and parasitic disease in the domestic animals of North America. The information given about each parasite includes habitat, distribution, life cycle, transmission, signs and pathogenicity, and control. Some of the commonly used laboratory techniques and diagnostic procedures are outlined, a host-parasite listing is provided, and there is additional information in the appendix about some of the parasiticides and chemotherapeutic agents which are mentioned in the text.

  PART I Protozoans
  PART I Protozoans
  (pp. 3-40)
  Disease: Babesiosis (bovine), Texas fever, red water fever, piroplasmosis.
  Host: Cattle, deer.
  Habitat: Erythrocyte.
  Identification: Trophozoites usually pyriform, may be round or oval, characteristically in pairs. Size is 2-3 µ in diameter and 4-5 µ long.
  Distribution and importance: Until eradication was a major cattle disease in the southern U.S. It is important to the U.S. because of possible introduction from Mexico.
  Life cycle: The trophozoite stage occurs in the erythrocyte where it multiplies by binary fission, budding, or schizogony. Reproductive stages are liberated from the erythrocyte and invade additional cells. Large numbers of erythrocytes may be parasitized.
  Transmission: In...

  PART II. HELMINTHS
  A. Nematodes
  A. Nematodes
  (pp. 43-109)
  Disease: Aelurostrongylosis.
  Host: Cat. Intermediate hosts are snails and slugs.
  Habitat: Lung parenchyma and terminal bronchioles. Eggs are found in alveolar ducts and alveoli, often in small nodules.
  Identification: Worms seldom recovered intact because they are deeply embedded in the parenchyma. Adults may be 10 mm. long; eggs are about 80 x 70 μ.
  Distribution and importance: Widely distributed throughout North America; not considered of marked clinical significance.
  Life cycle: Eggs hatch in the air passages, and larvae are passed in feces. After entering a mollusc, larvae become infective in about 18 days. A wide variety of snails and slugs...

  Disease: Anoplocephaliasis.
  Host: Horses, donkeys.
  Habitat:A. magna:Small intestine, occasionally stomach.A. perfoliata:Small and large intestine and cecum. It frequently occurs in colonies around the ileocecal valve.P. mamillana:Small intestine, occasionally stomach.
  Identification:A. magna:To 80 cm. long; scolex pronounced. Egg is 50-60 μ.A. perfoliata:To 8 cm. long; small head with lappets posterior to each sucker. Egg is 65-80 μ.P. mamillana:To 4 cm. long; suckers slitlike. Egg is 50 μ.
  Distribution and importance:A. magna:Cosmopolitan; not generally considered very important.A perfoliata:Heavy infections may significantly interfere with function of the...

  C. Trematodes
  C. Trematodes
  (pp. 128-141)
  Disease: Alariasis.
  Host: Dog. Various carnivores serve as hosts for other species.
  Habitat: Small intestine, often in duodenum.
  Identification: To 6 mm. long and about 2 mm. wide. At each side of the anterior end is a small earlike structure that is helpful in identification. The golden-brown egg is large, to 134 μ long and about 70 μ wide, and contains circular granular structures. The cercaria has a bifurcate tail.
  Distribution and importance: Essentially nonpathogenic as far as is known. However, the eggs are frequently seen on flotation fecal examination and may cause the veterinarian some concern.
  Life cycle: The...

  D. Acanthocephalans
  D. Acanthocephalans
  (pp. 142-144)
  Disease: Porcine acanthocephaliasis.
  Host: Pig.
  Habitat: Small intestine.
  Identification: Pseudosegmented appearance and often pale reddish. The adult may be 35 mm. long or more and 4-10 mm. wide; the cuticle is transversely wrinkled. A small proboscis extends from the anterior end and bears about 6 rows of transverse hooks. The egg is 100 x 65 μ and has 4 shells; the 2nd is brown and pitted.
  Distribution and importance: Generally found throughout the central and southern U.S. Its major significance is the damage to intestine that otherwise would be used for casings.
  Life cycle: The adult attaches to the intestinal...

  PART III. ARTHROPODS
  A. Arachnids
  A. Arachnids
  (pp. 147-171)
  Disease/Infestation: Argasid acariasis.
  Host: Chicken, turkey, and wild birds.
  Habitat: Adults and nymphs are active at night and hide during the day in cracks and crevices, under boards and tree bark. When a blood meal is desired, the host is attacked for only a short time. Larvae may attack day or night.
  Identification: Adults are at least 7 mm. long and 5 mm. wide. They are usually reddish-brown, but engorged ticks are slate-blue. Sexual dimorphism is slight. The ticks are flat and leathery, and the integument is wrinkled, bearing many minute setae. There is no shield (scutum).
  Distribution and importance:...

  B. Insects
  (pp. 172-196)
  Host: Man and many other species of warm-blooded animals.
  Habitat: Male mosquitoes are not bloodsuckers. They feed on nectar, plant juices, and other liquids. Female mosquitoes can pierce the skin of many kinds of animals and feed on blood. The female of bloodsucking species normally requires a blood meal before oviposition. Time of feeding is a species characteristic as is place of feeding. Some species feed indoors, and others feed outdoors. Habitats vary from large swampy areas, ponds, and lakes to tree holes, hoof tracks, discarded cans, and water barrels. The natural flight area of an adult is usually less...

  C. Linguatulids
  C. Linguatulids
  (pp. 197-198)
  Disease/Infestation: Linguatulosis.
  Host: Dog, fox, wolf.
  Habitat: Nasal and respiratory passages.
  Identification: This peculiar group of wormlike arthropods is related to the mites. The adults are internal parasites of nasal and respiratory organs of vertebrates. They are frequently tongue shaped and have an annulated cuticle which makes the body appear segmented. The female is 8-13 cm. long and the male, 1.2-2.0 cm. long. The yellow egg, about 90 × 70 μ, is oval and contains a larva bearing 4 hooklike structures. The head is not distinctly separated from the body. The anterior end has 5 ventral protuberances. The median opens...
