Detection of new viral encephalitis from cerebrospinal fluids of acute encephalitis syndrome patients in north VietNam

ABSTRACT

In the year 2002, a new arbovirus strain coded 02VN208 was isolated from cerebro- spinal fluid of patients with acute encephalitis syndrom by C6/36 mosquito cell lines. It’s a virus of 50nm spherical enveloped shape with ARN genetic materia. From a part of the extended sequence,specific primer pair was designed for determining the virus strains of the patients and the mosquitoes isolated by RT-PCR . 6 viral strains belonging to the same genotype of 02VN208 viral strain were confirmed. Results suggested that it’s a new arbovirus named Namdinh virus. Further study should be developed serologically and ultra morphologically
