Results: The proportion of Gram-negative bacilli rose obviously, so did the opportunistic pathogen's and Yeasts detected rate. Most drug sensitive tests showed the drug-fast rate turned to be high. Escherichia coli, Salmonella and Citrobacter resistant and so on to fluoroquinolones was 57%~97%. These bacteria to imipenem showed excellent activity. Meticillin-resistant-staphylococcus resistant to ciprofloxacin, norfloxacin, clindamycin, tetracycline, erythromycin, cefazolin and ampicillin were 40.9%, 42.4%, 63.6%, 72.2%, 85.9%, 100.0% and 100.0%, respectively Streptococcus and Enterococcus resistant to major β-lactams-penicillin, aminoglycosides, macrolides, tetracyclines and sulfonamides were between 36.0% to 100.0%.

结果：革兰阴性杆菌比例显著升高，条件致病菌和酵母样真菌检出机会显著增多；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和枸橼酸杆菌等革兰阴性杆菌对喹诺酮类药物的耐药率达57%~97%，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、头孢唑啉和氨苄西林的耐药率分别为40.9%、42.4%、63.6%、70.2%、85.9%、100.0%和100.0%；链球菌和肠球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物均呈高度耐药，耐药率在36%~100%。

To Dec. 2003 years in Yuxi city People's Hospital. RESULTS: The proportion of G－ bacilli were much. The opportunistic pathogen's and Yeasts detected rate rose obviously. Most drug sensitive tests showed the drug-fast rate turned to be high. Escherichia coli, Salmonella and Klebsiella and so on to fluoroquinolones was 50～97.7%. These bacteria to imipenem showed excellent activity. MRS resistant to ciprofloxacin, norfloxacin, clindamycin, tetracycline, erythromycin, gentamycin, trimeth/sulfa and cefazolin were above 50%. Streptococcus resistant to major β-lactams-penicillin, aminoglycosides, macrolides, tetracyclines and sulfonomides were highness.

结果：G－杆菌比例居多，条件致病菌和酵母样真菌检出机会显著增高；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和克雷伯菌等G－杆菌对喹诺酮类药物的耐药率在50％～97.7％，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、庆大霉素、复方新诺明和头孢唑啉的耐药率均在50％以上，链球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物呈高度耐药。

Furthermore, 13 Italian durum and 20 bread wheat cultivars and 11 Chinese wheat cultivars were also tested at seedling stage with 10 Italian isolates of pathogen.

在田间成株抗性监测中，12.2％和58.9%的硬粒小麦品种和面包小麦品种分别表现抗病或中抗；在苗期抗性鉴定中，参试的很多中国品种对大部分意大利菌株表现免疫、近免疫或高抗。

The endogenous level of IFN-γis an important index of body's cellular immune status. The quantitative determination of IFN-γconcentrations has very significant theorical and practical values in immune mechanism research,immune function assay,the efficacity evaluation of vaccine,transplant operation,hypersensitive reaction and intracellular pathogen diagnosis.

研究表明，内源性IFN-γ水平的高低在很大程度上可以反映机体的细胞免疫状态，因此对样本中的IFN-γ进行定量分析，在免疫机制研究、免疫功能分析、疫苗免疫效果评估、器官移植、过敏反应以及多种胞内病原感染的诊断等方面都具有极其重要的理论价值和应用价值。
