OBJECTIVE To study the circulation, distribution, and genomic diversity of HPVs in common warts in Beijing area of China. METHODS Forty eight patients with pathologically diagnosed common warts were screened for the presence of HPV with HPV type-specific PCR and direct sequencing analysis. The genomic diversity of HPVs prevalent in Chinese patients was analyzed based on LCR. RESULTS Forty o...

This study was to investigate the prevalence of HEV in pig herds under different breeding environment and in abattoirs located in Beijing, China. In total 638 sera samples and 114 liver samples were collected for a serological survey and a RT-PCR assay, respectively. The average prevalence rate of HEV in pig herds in Beijing suburb were 47.5-100%. Seropositive rate was 76.6% for pig herds of la...

The N and W-Beijing families of Mycobacterium tuberculosis are phylogenetically closely related. The ability of the W-Beijing family to rapidly cause widespread disease is well described; however, few outbreaks involving the N family have been reported outside the New York City, N.Y., area. During 2002 to 2003, Seattle, Wash., experienced a rapidly expanding tuberculosis outbreak involving 38 p...

BACKGROUND Multi Drug Resistant Tuberculosis (MDR TB) is a threat to global tuberculosis control. A significant fitness cost has been associated with DR strains from specific lineages. Evaluation of the influence of the competing drug susceptible strains on fitness of drug resistant strains may have an important bearing on understanding the spread of MDR TB. The aim of this study was to evaluat...

To the Editor: We read with interest the discussion between de Steenwinkel et al. and Werngren (1) regarding the high mutation frequencies de Steenwinkel et al. reported for some Mycobacterium tuberculosis strains (2). We investigated the effect of rifampin exposure on the growth of these strains in detail. We share Werngren’s surprise at the extraordinary mutation frequencies observed for the ...
