Consider to make clear in recent years, second acid is calcic - Bowman does not move bacillus clinical bacterium of single born of the same parents of the detached rate that go up and verdigris holiday comparatives, have the tendency that year after year rises, the fundamental condition pathogenic bacteria that already became the infection inside the courtyard [1] , have to a variety of antibacterial content be able to bear or endure higher property of a medicine [1, 2] , for this, we are monitored and statistic analysed my courtyard to came 1998 2004 7 years a second acid is calcic - the clinical infection condition that Bowman does not change bacillus, to 14 kinds of antibacterial content be able to bear or endure property of a medicine and be able to bear or endure medical tendency, sum up a report to be as follows now. 1 material and method all data all come from 1.1 basic materials to came on January 1, 1998 my courtyard outpatient service was mixed on December 31, 2004 the specimen sending check of inpatient, via clinical microbiology the lab is fostered and classics appraisal is second acerbity calcium - Bowman does not move bacillus to affect case of illness, with clinical and commonly used antibacterial at the same time content makes the kill that medical quick detects. 1.2 bacteria appraisal is mixed medical quick experiment uses live thing VITEK32 of Mei Li dust is full automatic the bacterial appraisal of bacterial analysis system and its form a complete set gets stuck and medical quick card undertakes detecting, 1998~2000 year use GNI appraisal gets stuck, 2001~2004 uses GNI+ card.

近年探究表明，乙酸钙-鲍曼不动杆菌临床上的分离率和铜绿假单胞菌相当，并有逐年上升的趋向，已成为院内感染的重要条件致病菌[1]，对多种抗菌药物有较高耐药性[1，2]，为此，我们监测并统计分析了我院1998年至2004年七年间乙酸钙-鲍曼不动杆菌的临床感染情况，对14种抗菌药物的耐药性及耐药趋向，现总结报道如下。1材料和方法1.1基本资料所有资料均来自于1998年1月1日至2004年12月31日我院门诊和住院病人的送检标本，经临床微生物学实验室培养并经鉴定为乙酸钙-鲍曼不动杆菌感染病例，同时以临床常用抗菌药物作药敏检测的结果。1.2细菌鉴定和药敏试验采用生物梅里埃VITEK32全自动细菌分析系统及其配套的细菌鉴定卡和药敏卡进行检测，1998~2000年使用GNI鉴定卡，2001~2004使用GNI+卡。

ASR1 is a gene from early auxin-responsive GH3 gene family, and the protein encoded by this gene is overexpressed in the mutant, which results in the following morphological phenotypes including dwarf, epinastic rosette leaves, and restrained lateral root formation, etc. Meanwhile, ASR1 may modify the plant defense signaling molecule salicylic acid in vivo, and therefore asr1 mutant is more susceptible to the infection from the pathogen Pseudomonas syringae.

ASR1属于生长素相关的GH3基因家族，它编码的蛋白质在突变体内过量表达，并造成植株矮化，莲座叶片向下卷曲，侧根发生受到抑制等形态表型的改变，同时，ASR1可能还参与了植物体对抗病信号分子水杨酸的调控或修饰过程，并使asr1突变体对病原菌丁香假单胞杆菌的侵染更敏感。

Methods From Feb 2006 to Jun 2006,188 hospitalized children in Shenzhen children s hospital, were collected deep tracheal aspirate at the time of hospitalization. The respiratory tract secretions were immediately sent for bacterial culture with 3 kinds of medium:ordinary medium, Hemophilus influenzae selective medium, Streptococcus penumoniae selective medium. Then we extracted the total nucleic acids from secretions, and detected Mycoplasma pneumoniae by single fluorescent quantitation PCR. Simultaneously, 14 respiratory tract pathogenic bacterium and Mycoplasma pneumoniae were detected by Target Enriched multiplex PCR. Amplification products were identified by the Luminex100 suspension array.
