There have more than toxic microbial and viruses in the list of bioweapon for the bioterrorism and biowar. The fights for bioterrorism and biodisaster are activities of society and community. Individuals and community have responsibilities to protect, fight, and reduce the damage timely and effectively to bioterrorism. The professional facilities are responsible for investigating, isolating the germs, toxics and implementing the effective solutions for management of outcomes of bioweapon.

In the year 2003, 525 specimens seem to be infected with Dengue fever/Dengue haemorrhagic fever in the Northern Vietnam were sent to the National Institute of Hygiene and Epidemiology, those specimens with IgM, IgG antibodies against Dengue virus was 85 cases (16.2%). In 2003, the number of Dengue fever/Dengue haemorrhagic fever was sporadic distributed in some provinces. Owing to active prevention of Dengue fever/Dengue haemorrhagic fever, so Dengue virus type 2 discovered early in Ha Tay, Thanh Hoa, Nghe An and Tay Nguyen provinces; Dengue virus type 1 in Ha Noi, Nghe An, Tay Nguyen provinces and Dengue virus type 4 in Ha Tinh, Thanh Hoa, and Tay Nguyen provinces

With the development of biomolecular technology, more human papillomavirus (HPV) types have been found to be related with various diseases. High-risk HPV 16, 18, 31, 33, 45, 52, and 61 have shown causal relationship with cancers of the cervix, vulva, vagina, penis, anus, oral cavity, and oropharynx. Low-risk HPV 6 and 11 have shown causal relationship with genital warts. HPV may also cause cancer of the larynx. However, the relationships between HPV and esophagus and lung cancers are still controversial.

The research on intracellular trafficking of adenovirus has been described mainly through observations of subgroup C adenoviruses in transformed cell lines. The basic elements of the trafficking pathway include binding to receptors at the cell surface, internalization by endocytosis, lysis of the endosomal membrane, escape to the cytosol, intracellular trafficking along microtubules, nuclear pore docking, and viral genome translocation into the nucleus. More than 80% of the adenovirus genome is delivered to the nucleus in a highly efficient manner in approximately 1 h. However, exceptions to this trafficking pattern have been noted, including: variations based on target cell type, cell physiology, and adenovirus serotype. This review summarizes mechanism of adenovirus infection pathway and intracellular trafficking, providinging a foundation for the development of clinical adenoviral vector.

OBJECTIVETo investigate the distribution of Hepatitis B virus genotypes and subgenotypes among patients with chronic hepatitis B in Xinjiang Uighur.

METHODSThe HBV genotypes and subgenotypes were analyzed by PCR-restriction fragment length polymorphism in 109 patients with chronic hepatitis B.

RESULTSTwo HBV genotypes, genotype C (45.9%) and genotype C/D (29.4%) were prevalent, genotype B (8.3%) and genotype D (16.5%) were also found in Xinjiang Uighur. Genotype C had two subgenotypes, C1 (54%) and C2 (46%). Genotype B had only one subgenotype, i.e. Ba. The subgenotype C2 was associated with cirrhosis and hepatocellular carcinoma.

CONCLUSIONIn Uygurs, the most common HBV genotypes were C and C/D, and the subgenotype C2 was associated with cirrhosis and hepatocellular carcinoma.

OBJECTIVETo evaluate the susceptibility of Aedes albopictus and Culex pipiens quinquefasciatus to oral infection with bat Japanese encephalitis virus isolates (GD1 and HN2 strains).

METHODSAedes albopictus and Culex pipiens quinquefasciatus were infected orally by GD1 and HN2 strains of bat Japanese encephalitis virus. TaqMan real-time PCR was used to detect the virus and monitor the changes in the viral loads in Aedes albopictus and Culex pipiens quinquefasciatus at a 2-day interval, starting from 4 days till 20 days after the infection.

RESULTSThe infected Aedes albopictus and Culex pipiens quinquefasciatus were found positive for the Japanese encephalitis virus from day 4 to day 20. Both Aedes albopictus and Culex pipiens quinquefasciatus were susceptible to infection by GD1 and HN2 strains, but the latter showed a greater susceptibility. The HN2 strain virus appeared to have a greater virulence than the GD1 strain.

CONCLUSIONAedes albopictus and Culex pipiens quinquefasciatus can carry GD1 and HN2 strains of bat Japanese encephalitis virus isolates.
