鲍曼不动杆菌（Acinetobacter baumannii）广泛存在

Acinetobacter baumannii (Acinetobacter baumannii) widely found in water and soil nature, hospital environment and human skin, respiratory, gastrointestinal and urogenital tract, are opportunistic pathogens. Bacteria is an important pathogen of nosocomial infections, mainly caused by respiratory infections, can also cause bacteremia, urinary tract infections. There is a rising trend of resistance to commonly used antibiotics rate, and cause serious concern of clinicians and microbiologists. <br>The wild-type P. aeruginosa obtained from the ATCC purchase, is provided by Roche to the HDB for its project study. Further four deletion mutant strain is derived from the strain ATCC gene,

Acinetobacter baumannii is widely found in natural water and soil, hospital environments and in the human skin, respiratory tract, digestive tract and genitourinary tract. The bacteria is an important pathogen of hospital infection, which mainly causes respiratory infection, but also causes bacteremia, urinary system infection and so on. The rate of resistance to commonly used antibiotics has been increasing year by year, and has aroused serious concern among clinicians and microbiologists.<br>The copper-green pseudomonas wild type was purchased by ATCC and provided by Roche to HDB for its project research use. The other four mutant strains were obtained by the gene deficiency of the ATCC strain.

Acinetobacter baumannii widely exists in water and soil, hospital environment, human skin, respiratory tract, digestive tract and urogenital tract, and belongs to opportunistic pathogens. It is an important pathogen of nosocomial infection, which mainly causes respiratory tract infection, bacteremia and urinary tract infection. The drug resistance rate of commonly used antibiotics is increasing year by year, which attracts the attention of clinicians and microbiologists.<br>The wild type of Pseudomonas aeruginosa was purchased by ATCC and provided by Roche company to HDB for its project research. The other four mutants were obtained from the deletion of ATCC gene,<br>
