| potential natural exposure of mississippi sandhill cranes to aflatoxin b1. | a survey was conducted to determine if carcinogenic mycotoxins were present in foods consumed by mississippi sandhill cranes (grus canadensis pulla). samples of field corn (zea mays) (n = 111) and chufa (cyperus esculentus) (n = 20), obtained in 1987, 1988 and 1989 on the mississippi sandhill crane national wildlife refuge (mscnwr) and nearby private lands were analyzed for aflatoxin b1(ab1), ochratoxin a and sterigmatocystin using thin layer chromatography. chufa samples were negative for all t ... | 1991 | 1758031 |
| presumed reactive polyarthritis and granulomatous vasculitis in a mississippi sandhill crane (grus canadensis pulla). | a 1.5-year-old female mississippi sandhill crane (grus canadensis pulla) was presented and managed for a polyarthritis of the intertarsal and tarsophalangeal articulations. results of aerobic bacterial cultures, mycoplasma species culture, and polymerase chain reaction testing of articular fluid did not identify any causative organisms. results of radiographs and cytologic examination of articular fluid were consistent with an inflammatory, nonerosive polyarthritis. the arthritis did not improve ... | 2013 | 24640933 |
| integrating microsatellite and pedigree analyses to facilitate the captive management of the endangered mississippi sandhill crane (grus canadensis pulla). | the minimization of kinship in captive populations is usually achieved through the use of pedigree information. however, pedigree knowledge alone is not sufficient if pedigree information is missing, questionable, or when the founders of the captive population are related to one another. if this is the case, higher levels of inbreeding and lower levels of genetic diversity may be present in a captive population than those calculated by pedigree analyses alone. in this study, the genetic status o ... | 2012 | 21604289 |
| environmental contaminants in nonviable eggs of the endangered mississippi sandhill crane (grus canadensis pulla). | our objectives were to determine if concentrations of environmental pollutants and microbial contamination in nonviable eggs of the endangered mississippi sandhill crane (grus canadensis pulla) contributed to egg failure. six eggs collected in 1990 and four in 1991 contained only background levels of organochlorine pesticides and polychlorinated biphenyls (pcbs), and tests for microbial contamination were all negative. two eggs contained late dead embryos, but neither revealed obvious abnormalit ... | 1994 | 24213965 |
