| northern bobwhites as disease indicators for the endangered attwater's prairie chicken. | because of limited access to the endangered attwater's prairie chicken (tympanuchus cupido attwateri), we used a related species, the northern bobwhite (colinus virginianus), as a surrogate for disease evaluation. free-living northern bobwhites (n = 62) on the attwater prairie chicken national wildlife refuge (near eagle lake, texas, usa) were examined during spring and fall 1993 for helminthic endoparasites and specific antibodies against the infectious agents responsible for nine infectious di ... | 1998 | 9577783 |
| reticuloendotheliosis in captive greater and attwater's prairie chickens. | reticuloendotheliosis in captive greater (tympanuchus cupido pinnatus) and attwater's (t. cupido attwateri) prairie chickens is reported for the first time. between september 1993 and august 1994, two adult female wild-caught greater prairie chickens housed at texas a&m university (college station, texas, usa) were observed with multiple subcutaneous nodules. both birds were euthanatized. complete necropsy examinations revealed lesions limited to the skin of each bird. histopathologic examinatio ... | 1998 | 9813849 |
| phylogenetic analyses indicate little variation among reticuloendotheliosis viruses infecting avian species, including the endangered attwater's prairie chicken. | reticuloendotheliosis virus infection, which typically causes systemic lymphomas and high mortality in the endangered attwater's prairie chicken, has been described as a major obstacle in repopulation efforts of captive breeding facilities in texas. although antigenic relationships among reticuloendotheliosis virus (rev) strains have been previously determined, phylogenetic relationships have not been reported. the pol and env of rev proviral dna from prairie chickens (pc-r92 and pc-2404), from ... | 2006 | 16497405 |
| eimeria attwateri n. sp. (apicomplexa: eimeriidae) from endangered attwater's prairie-chickens (tympanuchus cupido attwateri) in texas, usa. | abstract the attwater's prairie-chicken (apc; tympanuchus cupido attwateri bendire 1894) has been a federally listed endangered species since 1967. several captive propagation programs consisting of small populations are being used to keep this species from extinction. fecal samples were collected from apcs in april 2007 and again in august 2008 from two separate captive propagation facilities in texas after clinical signs of coccidiosis were observed. one eimeria species was observed, which we ... | 2011 | 21506827 |
| wild birds, a source of reticuloendotheliosis virus infection for the endangered attwater's prairie-chicken ( tympanuchus cupido attwateri)? | reticuloendotheliosis virus (rev) infects a wide range of avian species. since 1998, when it was first reported in a captive flock of the endangered attwater's prairie-chicken ( tympanuchus cupido attwateri; apc), rev has plagued apc recovery efforts. while rev frequently occurs in captive bird flocks throughout the world, including commercial poultry, the reservoir for initial infection of flocks is poorly understood. from 2008-2016, 412 blood samples and 216 liver samples collected from 32 spe ... | 2017 | 28192047 |
