| molecular evolution analysis and geographic investigation of severe acute respiratory syndrome coronavirus-like virus in palm civets at an animal market and on farms. | massive numbers of palm civets were culled to remove sources for the reemergence of severe acute respiratory syndrome (sars) in guangdong province, china, in january 2004, following sars coronavirus detection in market animals. the virus was identified in all 91 palm civets and 15 raccoon dogs of animal market origin sampled prior to culling, but not in 1,107 palm civets later sampled at 25 farms, spread over 12 provinces, which were claimed to be the source of traded animals. twenty-seven novel ... | 2005 | 16140765 |
| molecular epidemiology of sars-associated coronavirus, beijing. | single nucleotide variations (snvs) at 5 loci (17564, 21721, 22222, 23823, and 27827) were used to define the molecular epidemiologic characteristics of severe acute respiratory syndrome-associated coronavirus (sars-cov) from beijing patients. five fragments targeted at the snv loci were amplified directly from clinical samples by using reverse transcription-polymerase chain reaction (rt-pcr), before sequencing the amplified products. analyses of 45 sequences obtained from 29 patients showed tha ... | 2005 | 16229772 |
