Among which 70 were Gram-negative bacteria ( GNB ) and 9 were Gram-positive bacteria . The dominant bacterium was Pseudomonas aeruginosa in patients with VAP .

其中革兰阴性杆菌70株，革兰阳性球菌9株，VAP居首位的细菌是铜绿假单胞菌。

Small GTPase proteins play a pivotal role as important molecular switches , containing four guanine nucleotide ( GTP / GDP ) binding ( GNB ) domains and an effectors domain .

小GTPase蛋白作为重要的分子开关其结构域主要包括4个鸟苷酸（GTP/GDP）结合域及1个效应区。

The main VAP pathogenic bacterium in RICU was gram negative bacilli . As the time goes , the rates of the drug fast of some GNB strains of bacterium is increasing .

RICU呼吸机相关性肺炎病原菌主要以革兰阴性杆菌为主，随着时间变化，部分GNB菌株耐药率出现不同程度的上升。

To explore if the method comprising Limulus amoebocyte lysate ( LAL ) test and enumeration of total Gram-negative bacteria ( GNB ) can be used for screening of irradiated chicken .

CONCLUSIONS The major pathogens in VAP are GNB and there are often multiple drug-resistant . It is suggested that the adequate initial empiric antimicrobial treatment should base on the surveillance of etiology and resistance .

结论VAP的病原菌构成以GNB为主且呈现出多重耐药现象，适当的最初经验性抗菌治疗应依据于病原学和耐药性的监测结果。

Lipopolysaccharides ( LPS ) is an integral part of the outer membrane of all Gram-negative bacteria ( GNB ) and is considered to be the primary trigger of pathophysiologic events in sepsis .

脂多糖（LPS）是革兰阴性菌（GNB）细胞壁的主要成份，是GNB所致脓毒症多种病理生理反应的第一触发因子。

Objective To analyse the resistance retes of 200 gram-negative bacteria ( GNB ) strains from clinical isolates in 1998 and 1999 . Methods The E test was used to detect the MIC of 13 antibiotics in 200 GNB strains .
