Ten thin blood smears from mourning doves (Zenaida macroura) infected with Haemoproteus maccallumi were examined by each of two observers using identical techniques and microscopy in an attempt to delineate the factors necessary to provide an accurate estimate of the number of parasites/n erythrocytes. The number of erythrocytes examined must be actually(More)
Sarcoptic manage caused by Sarcoptes scabiei is responsible for epizootic disease in populations of wild canids in North America, Europe and Australia, wild cats in Europe and Africa, wild ungulates and wild boars in Europe, wombats and koalas in Australia, and great apes and various wild bovids in Africa. Although short-term mortality may appear(More)
Tetrameres (Tetrameres) tinamicola sp. n. is described from the crested tinamou, Eudromia elegans, of Argentina. The new species is most similar to other alate species of the subgenus Tetrameres, but it can be differentiated on the basis of its large size, length and structure of the left spicule, and arrangement of the 5 subventral and 3 sublateral pairs(More)
An epizootic of sarcoptic mange in coyotes from south Texas, Canis latrans , was studied over a 7-yr period, 1975 through 1981. From a four-county area centered in Webb County, Texas the epizootic radiated centrifugally to include a 27-county area. The disease progressed from initial, scabby encrustations on the ischium and fore and hind legs to severe,(More)
Two hundred thirty-one mallards (Anas platyrhynchos) collected during 1989-91 on the Southern High Plains of Texas were examined for macroscopically detectable Sarcocystis spp. Only eight adult mallards were infected. Based on small quantified tissue samples, five, one, and two birds had light, medium, and heavy infections, respectively. Prevalences were(More)
Seven species of helminths and six species of arthropods are reported from 23 of 40 brown pelicans, Pelecanus occidentalis, collected from various localities in Puerto Rico. Helminth parasites include three nematodes (Contracaecum multipapillatum, Contracaecum mexicanum, and Eustrongylides sp.), three trematodes (Galactosomum darbyi, Mesostephanus(More)
