Chinese scientists first finish genome-sequencing of SARS virus
Chinese scientists have become the first to complete the genome-sequencing o
f the severe acute respiratory syndrome (SARS) virus.
The breakthrough was achieved by the Beijing Genomics Institute of the Chine
se Academy of Sciences (CAS), which cooperated with the Microbe Epidemic Ins
titute of the Military Medicine Academy of Sciences.
On April 16, the World Health Organization (WHO) officially identified the c
orona virus as the cause of SARS. On this basis, scientists from both organi
zations also joined hands and efforts with Xie He Hospital and other clinics
, successfully developing a specific enzyme link immunoabsorbent assay for r
apidly testing SARS.
Kang Le, director of the biological bureau of the CAS, said this specific as
say would be mainly developed and produced at the Beijing Genomics Institute
.
Dr. Dong Wei, with the institute's genotyping group, said the test has been
put into use at all Beijing's designated hospitals for SARS, and in one week
, it could meet all of the country's requirements.
Yang Huanming, director of the Beijing Genomics Institute, said the assay is
accurate, sensitive, rapid, and convenient as well aseconomical. One assay
plate can test a total of 96 samples at the same time.
Most importantly, Yang said, the results can be known after one hour.
Scientists said once people get infected with SARS, their body would produce
specific antibody-countering virus proteins. The way the test works is this
virus proteins combine with specific antibodies and, through the enzyme lin
k reaction, the assay changes color, showing the virus is present.
Experts pointed out that the test will provide an accurate, reliable and rap
id as well as economical diagnosis means for controlling the disease's sprea
d. It will also play an important role in the prevention and diagnosis of SA
RS.
