Article Synopsis
- * 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].

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.
[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.
