Experimental cryptosporidiosis in broiler chickens.
TLDR
Weight gains for IT-inoculated birds were lower than controls from 14 to 21 DAI, although weight gains for the 5-week period were not significantly different, and effects of C. baileyi on immune responses were examined. Expand
EFFECTS OF COCCIDIAL AND MYCOPLASMAL INFECTIONS ON CAROTENOID-BASED PLUMAGE PIGMENTATION IN MALE HOUSE FINCHES
TLDR
Observations found that captive male House Finches experimentally infected with Isospora spp. Expand
Cultivation of Cryptosporidium baileyi: studies with cell cultures, avian embryos, and pathogenicity of chicken embryo-passaged oocysts.
TLDR
Sporozoites of Cryptosporidium baileyi did not undergo development in primary cell cultures from either avian or mammalian hosts, or in mammalian cell lines, as evidenced by the lack of gross lesions or death. Expand
Experimental Cryptosporidium infections in chickens: oocyst structure and tissue specificity.
TLDR
Oocysts of an avian isolate of Cryptosporidium were used to inoculate 21 chicks orally and 7 chicks intratracheally to determine the tissue specificity of this organism and cryptosporidia were found in the cloaca, bursa of Fabricius, terminal portion of the colon, and cecum of chicks that were positive for developmental stages.

Isolation and partial characterization of the insulin binding sites of Tetrahymena pyriformis.
TLDR
Not the isolation of a mammalian-like receptor protein, but a ciliary membrane protein (62-67 kDa) that is immunologically similar to insulin is reported that may function as both precursor to a soluble form and membrane-bound binding site/receptor as has been suggested for Euplotes pheromones and mammalian growth factors such as transforming growth factor a and epidermal growth factor.

MOLECULAR PHYLOGENY OF THE OTHER TISSUE COCCIDIA: LANKESTERELLA AND CARYOSPORA
Nearly complete sequences were obtained from the 18S rDNA genes of Eimeria falciformis (the type species of the genus), Caryospora bigenetica, and Lankesterella minima. Two clones of the rDNA geneExpand
Intracellular insulin binding in Tetrahymena pyriformis.
TLDR
It is unlikely that a cell surface structure similar to a mammalian insulin receptor exists in T. pyriformis, and several differences in protein composition between control and insulin-exposed ciliary membrane extracts, especially in the 30-50 kDa range are revealed. Expand
Experimental infections in domestic ducks with Cryptosporidium baileyi isolated from chickens.
TLDR
Results of this study indicate that ducks are more resistant to experimentally induced respiratory cryptosporidiosis caused by C. baileyi than are chickens and turkeys. Expand
Conventional and confocal microscopic studies of insulin receptor induction in Tetrahymena pyriformis.
TLDR
It is confirmed that T. pyriformis does bind insulin and that prior exposure to insulin increases the binding capacity for insulin in what may be a concentration-dependent manner. Expand
