The prevalence of coccidian parasites in passerine birds from South America.
Fecal samples were collected from 655 passerine birds representing 190 species from 13 collection sites in Guyana, Ecuador, Peru, and Argentina from August, 1990 - August, 1997 and the overall prevalence of coccidian parasites was 20.9% (137/655). Expand
Four new species of Isospora from the small tree finch (Camarhynchus parvulus) from the Galapagos Islands.
Four isosporan species are described from the small tree finch, Camarhynchus parvulus from Isabela Island on the Galapagos Archipelago, and one woodpecker finch was found to be infected with I. exigua, and a warbler finches, Certhidea olivacea was infected withI. Expand
Eimeria palumbi, a new coccidian parasite (Apicomplexa : Eimeriidae) from the Galapagos dove (Zenaida galapagoensis)
A new coccidian parasite found in Galapagos doves captured on Genovesa Island is described, which is the northeastern-most island in the archipelago and represents the only endemic columbiform species in the Archipelago. Expand
A new coccidian parasite, Isospora samoaensis, from the wattled honeyeater (Foulehaio carunculata) from American samoa
A new species of Isospora is described from the feces of the wattled honeyeater, Foulehaio carunculata from American Samoa, which consists of a large amorphous residuum composed of coarse granules and 4 randomly arranged, sausage-shaped sporozoites with a subspherical, posterior refractive body and a centrally located nucleus.

Efficacy of ionophorous anticoccidial drugs against coccidia in farm-reared pheasants (Phasianus colchicus) from Illinois.
Lasalocid at 120 ppm in the feed was the most effective, with nearly complete coccidiocidal activity against all four coccidial species, but the salinomycin-medicated pheasants gained the least of all medicated birds. Expand
The prevalence and seasonal distribution of coccidial parasites of woodchucks (Marmota monax).
The evidence presented in this study shows that the majority of first-stage larvae of Trichinella spiralis complete ecdysis within the intramulticellular niche, and some also accomplish this within the lumen of the small intestine, since the intestinal tract was perfused with fixative prior to sectioning.

Compensatory growth in broilers after withdrawal of ionophorous anticoccidial drugs.
Three polyether, ionophorous anticoccidial drugs were fed to broiler chickens in floor pens for 5 or 6 weeks, then withdrawn for 2 weeks or 1 week, respectively and there was evidence of increased feed consumption and compensatory growth in some treatments in which birds weighed more than controls prior to drug withdrawal.

Fecal samples from 237 nestling birds were collected from Daphne Major in the Galapagos archipelago and examined for coccidia, finding 3 infected nestlings had concurrent infections of Isospora temeraria, and all 3 nestlings were infected with a new species. Expand
Isospora geospizae, a new coccidian parasite (Apicomplexa: Eimeriidae) from the small ground finch (Geospiza fuliginosa) and the medium ground finch (Geospiza fortis) from the Galapagos Islands
Isospora geospizae n. sp. is described from the faeces of the small ground finch Geospiza fuliginosa and the medium ground finch Geospiza fortis from Santa Cruz Island in the Galapagos archipelago.Expand
