| molecular characterization of cryptosporidium sp. isolated from northern alaskan caribou (rangifer tarandus). | cryptosporidium sp. was found in 3 out of 49 caribou (rangifer tarandus) from northern alaska. segments of both the 18s ribosomal rna and the heat shock protein genes were amplified from the caribou isolate and compared with that obtained from an isolate from a wild white-tailed deer (odocoileus virginianus) in virginia as well as other species and isolates available from genbank. analyses showed the white-tailed deer isolate to be identical with the c. parvum cattle genotype; however, the carib ... | 2002 | 12053974 |
| prion protein genes in caribou from alaska. | prion protein genes were sequenced in free-ranging alaska caribou (rangifer tarandus grantii). caribou prion alleles are identical or nearly so to those of wapiti, white-tailed deer, and mule deer. five single-nucleotide polymorphisms were detected with substitutions at residues 2 (v-->m), 129 (g-->s), 138 (s-->n), 146 (n-->n), and 169 (v-->m). the 138n codon had been previously reported only in prion pseudogenes of other cervids. in caribou, the 138s and 138n alleles are present at frequencies ... | 2007 | 17495306 |
| dermoid cysts in caribou. | subcutaneous dermoid cysts were identified in eight wild caribou (rangifer tarandus) from widely dispersed locations in northern canada and in one wild caribou from alaska. the dermoid cysts from canadian caribou were found among 557 diagnostic specimens that had been detected by hunters and submitted by resource officers and biologists between 1 january 1966 and 15 may 2007. all of the cysts were located in the cervical region, and five of nine cysts were found in the throat area. all of the an ... | 2009 | 19395761 |
