A microbial ecosystem is a complex community of multiple bacterial interactions. The potential role of gut microbiota in human health has already attracted the attention of many researchers. Dysregulation of the gut microbial community has been suggested to be closely associated with the progression of various chronic diseases.

- * Milk was treated with NaOH and mycobacteria were isolated using L-J medium, followed by identification through PCR and gene analysis, revealing it to be Mycobacterium elephantis.
- * The identified strain showed resistance to some antibiotics while being sensitive to several others, marking the first report of M. elephantis isolation from cow milk in China.
[Study on the identification characteristics of rRNA genes on Yersinia pestis].
Zhonghua Liu Xing Bing Xue Za Zhi
April 2011
Objective: To study the identification characteristics of rRNA genes on Yersinia (Y.) pestis.
Methods: By means of comparative genomics, we compared the rRNA genome sequences of nine completely sequenced strains of Y.
Objective: To investigate the molecular characteristics of phage-type 6b isolates emerging in 1998-2001 cholera epidemics in Sichuan province.
Methods: Isolates were analyzed by phage-typing, pulsed field gel electrophoresis (PFGE) and ompW gene sequencing.
Results: All phage-type 1b and 6b isolates in Sichuan province from 1998 to 2001 were toxigenic.
[Study on the application and evaluation of methods for gene and antigen detection in plague surveillance program].
Zhonghua Liu Xing Bing Xue Za Zhi
May 2007
Objective: To apply and evaluate new methods regarding specific gene and antigen detection in plague surveillance program.
Methods: 1798 samples from natural foci of plague were tested, using internal quality control multiple-polymerase chain reaction, F1 antigen marked by immuno chromatographic assay and enzyme linked immunosorbent assay. Culture of Yersinia pestis and reverse indirect hemagglutination assay were used as reference diagnostic methods.
[Use of variable-number tandem repeats to examine genetic diversity of Bacillus anthracis].
Zhonghua Liu Xing Bing Xue Za Zhi
August 2006
Objective: To study the genotyping of Bacillus anthracis based on multiple-locus variable-number tandem repeats(VNTR) in the B. anthracis genome.
Methods: We selected 13 VNTR loci (which cited from published articles) to study 88 strains of B.
