background: the number of reported cases, infected with carbepenem resistant acinetobacter baumannii (crab) and multi-drug resistant (mdr) acinetobacter species had gradually increased in most pla general hospital wards from april to june in 2007. objectives: we have described the investigation of an outbreak of crab and mdr acinetobacter in pla general hospital, beijing. the prospective and re...

Allelic variation among Helicobacter pylori vacA occurs in the signal and middle region of the gene. The aim of the study was to investigate alleleic variation of vacA among H. pylori strains from three regional areas of China and the relationship between vacA alleles and PUD. DNA extracted from 88 clinical isolates of H. pylori was analyzed by type-specific PCR and reverse hybridization line p...

To investigate the molecular characterization of multidrug-resistant tuberculosis (MDR-TB) isolates from China and the association of specific mutations conferring drug resistance with strains of different genotypes, we performed spoligotyping and sequenced nine loci (katG, inhA, the oxyR-ahpC intergenic region, rpoB, tlyA, eis, rrs, gyrA, and gyrB) for 128 MDR-TB isolates. Our results showed t...

The standard 15- and 24-locus variable-number tandem repeat (VNTR) genotyping methods have demonstrated adequate discriminatory power and a small homoplasy effect for tracing tuberculosis (TB) transmission and predicting Mycobacterium tuberculosis lineages in European and North American countries. However, its validity for the definition of transmission in homogenous M. tuberculosis populations...

With its airborne transmission and prolonged latency period, Mycobacterium tuberculosis spreads worldwide as one of the most successful bacterial pathogens and continues to kill millions of people every year. M. tuberculosis lineage 1 is inferred to originate ancestrally based on the presence of the 52-bp TbD1 sequence and analysis of single nucleotide polymorphisms. Previously, we briefly repo...
