葡萄球菌

Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.

The results indicate that (1) After acclimation and induction, Phosphorus Accumulating Organism not only has the characteristics of denitrification, but also has the characteristics of takeup phosphate in aerobic;(2) Denitrifying phosphate accumulating bacteria using NO3- as electron acceptor indeed existed in the conventional enhanced biological phosphorus removal system;(3) The facultative anaerobe seperated during the process of acclimation are Corynebacterium, Pseudodiphtheria corynebacterium, Staphylococcus and Moraxella; all of which can be functioned as denitrifying phosphorus accumulating to various degree.

试验结果表明：(1)好氧聚磷菌经驯化诱导后不但具有反硝化产氮特性，而且具有好氧聚磷特性；(2)在传统的A2O 工艺中存在有以NO3-为电子受体的反硝化聚磷菌；(3)在驯化过程中分离到的兼性厌氧微生物有棒状杆菌属、假白喉棒杆菌、葡萄球菌属及莫拉氏菌属，且都有不同程度的反硝化聚磷功能。

Three classes, forty-eight in total, of pyrazole compounds, imidazolo[1,2-b] pyrazoles, dipyrazolylmethanones and pyrazolyloxadiazoles, have been synthesized, and they have been fully characterized by modern spectroscopic methods, two of which were further confirmed by X-ray diffraction. Most of these compounds have been evaluated for the inhibitions of Gram-positive bacterium represented by Staphylococcus aureus and Gram-negative bacterium represented by Klebsiella pneumoniae.

论文合成了咪唑并[1，2-b]吡唑类、二吡唑基甲酮类和吡唑连噁二唑类共三类48个化合物，使用了现代结构测试手段对所合成的化合物进行了结构表征，其中两个化合物经过了X-Ray射线衍射分析，并对其中大部分化合物进行了以金黄色葡萄球菌和肺炎克雷白杆菌为代表的革兰氏阳性菌和革兰氏阴性菌的初步抑菌活性测试。

Antibiotic susceptibility tests were carried out by K-B diffusion method on 41 vibrio strains isolated for one year both from farming seawater (18 strains) and digestion guts (23 strains) of the cobia, Rachycentron canadum . We chose 10 different species of antibiotics and refered to NCCLS performance standards for antimicrobial susceptibility testing, while taking Staphylococcus aureus ATCC25923 and Esсheriсhia coli ATCC25922 to control the test.

选用常用的10种抗生素，通过纸片扩散法（Kirby-Bauer纸片扩散法，简称K-B法），参照NCCLS抗生素敏感试验操作标准，并以金黄色葡萄球菌 Staphylococcus aureus ATCC25923和大肠埃希菌Esсheriсhia coli ATCC25922为质控菌株，对周年监测分离自养殖军曹鱼水体及肠道的41株优势弧菌（水体菌18株，肠道菌23株）进行了药物敏感性研究。
