| [human coronavirus-nl63 was detected in specimens from children with acute respiratory infection in beijing, china]. | a new human coronavirus, hcov-nl63, was identified recently from two dutch children with acute respiratory infection (ari) by two scientists in the netherlands in 2004. to investigate if this newly discovered virus is associated with acute respiratory infections in pediatric patients in beijing, tests were developed to detect hcov-nl63 gene fragments from throat swab and nasopharyngeal aspirates collected from children in outpatient and inpatient departments with ari in beijing from dec. 2003 to ... | 2006 | 16624059 |
| 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 |
| genetic variation of sars coronavirus in beijing hospital. | to characterize genetic variation of severe acute respiratory syndrome-associated coronavirus (sars-cov) transmitted in the beijing area during the epidemic outbreak of 2003, we sequenced 29 full-length s genes of sars-cov from 20 hospitalized sars patients on our unit, the beijing 302 hospital. viral rna templates for the s-gene amplification were directly extracted from raw clinical samples, including plasma, throat swab, sputum, and stool, during the course of the epidemic in the beijing area ... | 2004 | 15200810 |
| real-time polymerase chain reaction for detecting sars coronavirus, beijing, 2003. | during the 2003 severe acute respiratory syndrome (sars) outbreak, a real-time quantitative polymerase chain reaction, which targets the nucleocapsid gene at the 3' end of the viral genome, was established to detect and identify the sars-associated coronavirus. we describe the use of this assay to screen >700 clinical samples. | 2004 | 15030701 |
