Across
- 2. horn/face fly of cattle; bigger issue in cattle - reproduce in manure, but can affect horses house near cattle too; cs - ventral midline dermatitis, fairly focal lesions with wheals/crusts, non pruritic
- 4. vector for habronema muscae, stomoxys calcitrans
- 6. vector for onchocerca cervicalis that causes dermatitis in cattle/horses due to hypersensitivity of dying microfilaria; CS - diamond shaped lesions/bulls eye on head, ocular lesions (uveitis, conjunctivitis, keratitis) due to aberrant migration, ventral midline dermatitis; non seasonal/nonpruritic; tx - ivermectin
- 7. cochliomyia hominivorax; eradicated from US by releasing sterile males(reportable); CS- myiasis: eggas laid in wounds, may see metallic blue-green fly leaving wound
- 14. most economically important in swine; severely pruritic, hyperkeratotic ear lesions; decreased growth, dec milk production (cow), hide damage; horse- around the neck and ears; ZOONOTIC & REPORTABLE; tx - ivermectin
- 15. cat disease transmitted by dermacentor that rapidly progresses and almost 100% fatal causing dark urine, icterus, fever, prolonged CRT DIC and anemia characterized by ring shaped organism in RBC or schizonts in organ
- 17. cattle, (+dogs/horses) malaria like parasite transmitted by boophilus ticks. causes RBC destruction. greyhounds and pibbles are predisposed
- 18. cats and dogs become infected by close contact with rodents (esp rabbits) ZOONOTIC, CS are depression, fever, anorexia, lymphadenopathy, oral ulceration
- 20. lay term for culicoides hypersensitivity type 1 due to the saliva of the gnat; common in warm months (seasonal) and worsens with age. vector for blue tongue & onchocerca. tx - dec exposure and steroids
- 22. warble/heel fly attaches eggs to hairs on feet of cattle/horses, L1 burrows/hatch into skin; bovis migrates to epidural fat of SC; lineatum migrates to esophagus; both cause nodules with a pore on the top; tx - ivermectin in early fall
- 23. disease caused by ehrlichia ruminantium transmitted by amblyomma causing fatal encephalitis in sheep/goats/cattle
- 24. dictyocaulus viviparous in horses; dx w/tracheal wash, baermann fecal analysis; tx - fenbendazole/ivermectin/levamisole/albendazole
- 25. cattle disease causing extra vascular hemolysis with no hemoglobinuria. new additions to herd are weak, depressed, staring into space, pale/icteric
- 26. clinical signs are the same as ehrlichia but are gone in 2 weeks, transmitted by dermacentor aka rickettsia rickettsii
- 27. cattle are IH, prevent by eliminating carnivore feces from the area; s. hirsuta (cat), hominis (human), cruzi (dog); lifecycle - carnivore eats cow with cysts in muscle which form sporocysts shed in feces, eaten by cows which then hatch and invade muscle in form of cysts in 10 weeks
Down
- 1. lay term for habronema muscae = stomach worm; larvae migrate and emerge creating granulomatous lesions (eye, genitalia, lower extremities), gastritis, eosinophilic granulomas
- 3. vector for trypanosomiasis; nagana in cattle & sleeping sickness in humans
- 5. transmitted by ixodes from usually white-footed mouse, humans have CLM, dogs get arthritis, lymphadenopathy, fever and anorexia aka borrelia burgdorferi
- 6. equine mange mite that causes lesions near the foot and fetlock (esp draft horses) - see on head/neck/withers; dx - skin scrape; only form of manage that isn’t reportable; causes colic/death in horses
- 8. species affected by oestrus ovis - a fly that deposits larvae in nostrils causing sneezing/head shaking/nose rubbing/nasal discharge/stridor; cytology - eosinophils and mast cells; tx ivermectin
- 9. 6 legged, type of lice in cows, hematopinus; causes severe anemia in calves 2-7mo; dx via skin scrape
- 10. aka foothills abortion, transmitted by ornithodoros coriaceus; aborted fetus shows enlarged lymph nodes/spleen, destructive lesion to thymus
- 11. transmitted by a soft tick found in swine that causes fever, inappetance, hemorrhages in skin of ears, acute death
- 12. melophagus ovinus, have 6 legs - wingless flies and adults feed on blood; CS - pruritis, stained wool, potentially anemia
- 13. the definitive host for a horse lung worm (d. arnfeldi), seen in horses housed near these animals
- 16. transmitted by amblyomma and rhipicephalus causing fever, anorexia, edema of limbs, joint pain, depression, oral vesicles, petechiae, aqueous flare, hypoALB inc ALP
- 19. neospora caninum causes what in cattle 4-6months of gestation; dog is DH; usually see autolysis of fetus with granulomas in the brain
- 21. “eye worm” spread by musca autumnalis (facefly of horse); tx - removing manually then add 10% levamisole drops
