Nine structural genes (furA, katG, inhA, kasA, Rv0340, iniB, iniA, iniC, and efpA) and two regulatory regions (the oxyR-ahpC intergenic region and the promoter of mabA-inhA) in 87 isoniazid (INH)-monoresistant and 50 INH-susceptible Mycobacterium tuberculosis isolates collected from five provinces of China were analyzed by sequencing. Eighty-two (94.3%)(More)
The interleukin (IL)-17 gene plays a key role in host defence against infections from microbes, including Mycobacterium tuberculosis. Genetic factors contribute to host defence. However, whether genetic variation in IL-17 is associated with altered susceptibility to tuberculosis is unknown. A total of 596 pulmonary tuberculosis (PTB) patients, 176(More)
Genetic factors play important roles in the development of tuberculosis (TB). SP110 is a promising candidate target for controlling TB infections. However, several studies associating SP110 single nucleotide polymorphisms (SNPs) with TB have yielded conflicting results. This may be partly resolved by studying other genes associated with SP110, such as(More)
Levels of IL-18 were significantly lower in women with recurrent miscarriage (RM) than those without idiopathic RM. IL-18 promoter single nucleotide polymorphisms were previously identified to have an impact on IL18 gene transcription activity and influence the level of IL-18 protein production. The aim of this study was to evaluate whether IL-18 gene(More)
Ethanol production from corncob residues (CCR) pretreated by different methods was studied. The structure features of these CCR were analyzed by Fourier transform-infrared spectrum (FT-IR), X-ray diffraction (XRD), and field emission scanning electron microscope (SEM). Simultaneous saccharification and fermentation (SSF) was performed by adding crude(More)
OBJECTIVE To examine the global effects of Mycobacterium tuberculosis (M. tuberculosis) infection on macrophages. METHODS The gene expression profiling of macrophage U937, in response to infection with M. tuberculosis H(37)R(a), was monitored using a high-density cDNA microarray. RESULTS M. tuberculosis infection caused 463 differentially expressed(More)
A new PCR-reverse dot blot hybridization (RDBH) assay was developed for the rapid identification of Mycobacterium species in clinical isolates. The assay, which targets the 16S rRNA, was evaluated for 27 mycobacterial reference strains and 340 clinical isolates that were simultaneously identified by DNA sequencing and conventional methods, including growth(More)
Mutations in the 81-bp rifampin resistance determining region (RRDR) and mutation V176F locating at the beginning of the ropB gene were analyzed by DNA sequencing of 86 Mycobacterium tuberculosis clinical isolates (72 resistant and 14 sensitive) from different parts of China. Sixty-five mutations of 22 distinct kinds, 21 point mutations, and 1 insertion(More)
