OBJECTIVE To study the pathogen distribution and drug-resistance status of Gram-negative bacillary pneumonia and draft preventive and control measures.METHODS The sputum and lower respiratory tract secretion of 268 patients with Gram-negative bacillary pneumonia were cultured to detect pathogens.Susceptibility test was performed.Then the results were analyzed retrospectively.RESULTS Detection rates of Pseudomonas aeruginosa rated the top one,reaching 29.9%;then was Klebsiella pneumoniae,accounted for 19.4%;Acinetobacter baumannii ranked the third,accounted for 15.3%.The drug-resistance supervision manifested that the resistant rate of Gram-negative bacteria to ampicillin was the highest,reached 81.6-94.7%;that to imipenem was the lowest,reached 0-2.5%.And extensive-spectrum beta-lactamases(ESBLs) occurred with 30.0%.CONCLUSIONS The higher drug-resistance to common antibiotics occurs in Gram-negative bacillary pneumonia in our hospital.Clinical microbiology department should monitor pathogens well to provide the evidence for infection controlling.

OBJECTIVE To formulate the effective measurement to prevent and control nosocomial infection in blood transfusion department.METHODS The hidden danger of nosocomial infection in our hospital was investigated to formulate the practicable strategy of precaution and control.RESULTS Management status in blood transfusion department occurred several administration shortages such as unreasonable overall arrangement,flaw regulatory regime,weak precaution consciousness,nonstandardized contamination zonation,deficient management of medical garbage disposal,etc.CONCLUSIONS Executing strictly laws and regulations,establishing relevant rules and carrying on standardized administration are essential for prevention and control of nosocomial infections in blood transfusion department and for assurance of biosafety.

OBJECTIVE To investigate distribution status and drug-resistance of pathogens from infected urinary tract and offer scientific evidence for reasonably clinical usage of antibiotics.METHODS A total of 336 strains of pathogenic bacteria isolated from urinary tract infection from 2003 to 2007 were identified,and antibiotic susceptibility test was performed by K-B methods.RESULTS The total isolating rate of Gram-negative bacilli was 78.3%.And that of Gram-positive cocci was 16.4%.Escherichia coli accounted for 64.9%,ranking the first.Except for 100% sensitive to vancomycin in Gram-positive cocci and 100% sensitive to imipenem in Gram-negative bacilli,all pathogens were resistant to the other antibiotics in different degrees.The detection rate of extensive-spectrum beta-lactamases(ESBLs) producers in E.coli and Klebsiella pneumoniae were 25.7% and 28.0%,respectively.CONCLUSIONS The drug-resistance of pathogenic bacteria from infected urinary tract emergs in Yinshan County.We should adopt effective measurement to prevent and control it.
