A case report of spontaneous abortion caused by Brucella melitensis biovar 3.

Background: Brucellosis is a worldwide zoonotic disease caused by Brucella spp. Brucella invades the body through the skin mucosa, digestive tract, and respiratory tract. However, only a few studies on human spontaneous abortion attributable to Brucella have been reported.

[RelE toxin protein of Mycobacterium tuberculosis induces growth inhibition of lung cancer A-549 cell].

Objective: To investigate whether the RelE toxin protein of mycobacterium tuberculosis has a growth inhibition effect on lung cancer A-549 cell.

Methods: The complete open-reading frame sequences of RelE, RelB and RelBE genes were amplified by PCR with using M. tuberculosis H37Rv genomic DNA as the template.

[Effect of transfected Rv0901 gene on the activity of mice macrophages].

Objective: To test the effect of Rv0901 gene of Mycobacterium tuberculosis on the activity of mice macrophages.

Methods: Peritoneal macrophages of mice were isolated and transfected with pcDNA3. 1 or pcDNA3.

[Molecular cloning and expression of hypothetical proteins Rv1494 and Rv1495 of M.tuberculosis H37Rv strain].

Objective: The mechanism by which M.tuberculosis persists and survives in host macrophage is not fully understood, however, the M. tuberculosis chromosome-encoded TA loci perform functions possibly of signaling to these processes.
