8. A client was out hunting with her Cooper’s hawk, which caught a mourning dove. After taking the mourning dove from her hawk, she noted the lesions below. She said she has fed several other doves with similar lesions to her hawk before, but has become concerned, as he seems to need greater amounts of food to keep him at hunting weight than usual. What is likely going on in this dove (4 rule outs), how would you definitively diagnose, is it a concern for her hawk, how would you treat it if it is?
|
a. Trichomonas gallinae, poxvirus, candidiasis, capillariasis, vitamin A def

9. A client who fancies himself a gamebird aficionado contacts you because he has lost several wild turkeys (some of which had passed sulfur yellow feces). His bobwhite quail and Hungarian partridges are fluffed up and not eating as well. His recently added ring-necked pheasants are fine. On necropsy you find the following gross lesions involving the liver and cecal plug. What is your tentative diagnosis? What should he do to treat the sick birds and also manage the flock long term?
|
Histomoniasis is capable of causing catastrophic losses in the wild turkey. Histomonas meleagridis, utilizes cecal worm, Heterakis gallinarum (nematode), as a vector for entry into the bird hosts. The disease commonly called blackhead. Earthworms feed on fecal-contaminated soil that contains cecal worm eggs infected with histomonads. The cecal worm larvae and histomonads are stored in the body of the earthworm and are transmitted. However, earthworms are not required for the life cycle; cecal worm larvae that contain histomonads may be ingested. Turkey, grouse, chicken, and partridge develop severe disease and suffer high mortality rates. Disease is less severe in Hungarian partridge and bobwhite quail. In contrast, pheasant and some other species often do not exhibit signs of disease, but they instead become carriers that maintain the disease cycle. Wild turkeys affected with this disease often are listless, have an unthrifty appearance of ruffled feathers, and stand with drooped wings. The birds may appear depressed, and their feces are often sulfur-yellow in color. This fecal coloration generally occurs early in the disease and, combined with other field signs, it is highly suggestive of histomoniasis. The primary gross lesions seen upon necropsy of infected birds are numerous large, pale grey, discrete circular crater-like areas of necrosis or tissue death within the liver and thickened caecal walls that often also become ulcerated and hemorrhagic. The lumen of the ceca may also be obstructed by aggregations of yellowish necrotic debris referred to as cecal cores. Elimination of pheasant carriers would be important and removal of top soil. Because chickens are often carriers of H. gallinarum (cecal worms), and often shed histomonads, spreading uncomposted chicken manure onto fields can distribute cecal worm eggs to wild and susceptible species. So do not do that!
