摘要： The present invention relates to a high-throughput diagnostic assay for the virus causing Severe Acute Respiratory Syndrome (SARS) in humans (“hSARS virus”). In particular, the invention relates to a high-throughput reverse transcription-PCR diagnostic test for SARS associated coronavirus (SARS-CoV). The present assay is a rapid, reliable assay which can be used for diagnosis and monitoring the spread of SARS and is based on the nucleotide sequences of the N (nucleocapsid)-gene of the hSARS virus. The present method eliminates false negative results and provides increased sensitivity for the assay. The invention also discloses the S (spike)-gene of the hSARS virus. The invention further relates to the deduced amino acid sequences of the N-gene and S-gene products of the hSARS virus and to the use of the N-gene and S-gene products in diagnostic methods. The invention further encompasses diagnostic assays and kits comprising antibodies generated against the N-gene or S-gene product.

摘要： The present invention provides the complete genomic sequence of a novel human coronavirus, coined as coronavirus-HKU1 (“CoV-HKU1”), isolated in Hong Kong from a patient who had a recent history of visit to Schenzhen, China. The virus belongs to the order Nidovirales of the family Coronaviridae, being a single-stranded RNA virus of positive polarity. The invention also provides the deduced amino acid sequences of the complete genome of the CoV-HKU1. The nucleotide sequences and deduced amino acid sequences of the CoV-HKU1 are useful in preventing, diagnosing and/or treating the infection by CoV-HKU1. Furthermore, the invention provides immunogenic and vaccine preparations using recombinant and chimeric forms as well as subunits of the CoV-HKU1 based on the nucleotide sequences and deduced amino acid sequences of the CoV-HKU1.
