[Cloning and Bioinformatics Analysis of Toxoplasma gondii ROP21 Gene].

The full-length gene sequence of Toxoplasma gondii ROP21 (TgROP21) gene was amplified with PCR. The signaling peptide and transmembrane domain of TgROP21 protein were predicted by SignaIP and TMHMM online predictive sites, and the hydrophilicity and antigenic index of this protein were ananlyzed with DNAStar software. Meanwhile, the functional domains and tertiary structure were modeled by combined use of ExPASY and PRODATA online sites.

[The evolution of detection strategy for tuberculosis (TB)].

As one type of chronic respiratory infectious disease, the detection of tuberculosis (TB) is the most important aspect to control, prevent and treat TB. With the constant improvement of cognition of TB and development of related test methods, the evolution of detection strategy for tuberculosis went through three stages, that is spontaneous discovery stage, positive discovery stage, and integrated stage of primary passive discovery and supplementary positive discovery. At present, the detection for TB ought to be an integrated detection strategy of primary passive discovery and supplementary positive discovery.
