Surveillance of the mutation of gene encoding Vi antigen of Salmonella typhi isolated in Vietnam during 1995 and 2005

Background: Salmonella typhi (S.typhi) is the major cause of human typhoid fever outbreaks. In fact, there were various typhoid fever outbreaks that occurred in China, and India that was caused by S.typhi strain without Vi antigen. Objective: To determine whether the S.typhi strains with mutation of gene encoding Vi antigen exists in Vietnam and the rate of mutation (if they exists). Subject and methods: 450 S.typhi isolates were collected in the Northern, Central and Southern Region of Vietnam during 1995 and 2005. The isolates were analyzed by the PCR method in order to detect mutants by using 2 primer pairs of tviB and DE. Results and Conclusion: There was no clear evidence on the relationship between the widely used Typhi Vi vaccine in Vietnam and the existence and spread of the mutation of gene encoding Vi antigen of S.typhi. 30 out of 450 isolates mutated losing the gene encoding of Vi antigen, making it 6.67%. These isolates were spread out between 1995 and 2005 throughout the Northern, Central and Southern Regions of Vietnam, with a peak in 1999. A noteworthy point was the rate of mutation of S.typhi losing the gene encoding of Vi antigen in Vietnam during the period of study. However, the mutation rate of S.typhi in Vietnam was still higher than the ratio of similar mutations being published in the other countries worldwide and higher than the recommended level of the World Health Organization.

Investigating favorable factors and treatment responses in the patients with biliary ascariasis who admitted to Hue Central Hospital

Between 1990 to 1994, 217 patients were diagnosed with biliary ascariasis by ultrasonography. It was showed that biliary ascariasis is a pathological condition with excess incidence. Treatment in complicated or pregnant cases is difficult and costly. Some factors, especially female gender, pregnancy, and pH level of biliary fluid can influence favorably to the migration of ascarid. Ascarid infection density does not affect to the relapse frequency. Use helminthics early with single dose can provide the pain relief rapidly, reduce the rate of complication and avoid overuse the anti-spasmodics. The patients with history of biliary asariasis relapses should be followed-up and treated actively.
