ABSTRACT
Objective To analyze the popular characteristic and drug resistance of Pseudomonas aeruginosa in a hospital of Guiy-ang from January 201 1 to December 2013.Methods The distribution characteristic and drug resistance of Pseudomonas aeruginosa isolated from clinical samples from January 201 1 to December 2013 were analyzed retrospectively.Results A total of 642 strains of Pseudomonas aeruginosa were isolated for three years in our hospital from January 201 1 to December 2013,there was 57.0% isola-ted from sputum specimens,and 27.9% isolated from excreta of wound.The infected endemic area distribution was made up of Or-thopedic Surgery,ICU,Geriatrics Department and Respiratory Department accounting for 22.9%,20.1%,18.8% and 1 5.9% re-spectively.Pseudomonas aeruginosa was most sensitive to polymyxin bacillosporin.The drug resistance rates to Trimethoprim,Am-picillin and Cefazolin were all 100.0%.The drug resistance rates to Ampicillin/sulbactam and Ceftriaxone were 90.0%. Conclusion Pseudomonas aeruginosa is the main cause of lower respiratory tract infections in patients and wound infection and show serious multi-drug resistant,so it is necessary to use drugs reasonably according to the drug susceptibility results.
ABSTRACT
Objective To explore the efficacy and safety of mosapride combined withpancreatic kallikrein in the treatment of diabetic neurogenic bladder(DNB).Methods According to the digital table,120 patients with DNB were randomly divided into the control group and the observation group,each group 60 cases,All patients received basic treatment,including reducing blood glucose,reducing blood pressure,nutrition nerve and regulating blood lipids,and the observation group was accepted the treatment of original enzyme plus mosapride pancreatic kinin on basis of the above treatment.The treatment time of the two groups was both 3 weeks,The effect,blood sugar,blood hpids,urodynamic,quality of life,and the incidence of adverse reactions were observed.Results The total effective rate of the observation group was 93.33％,which was significantly higher than that of the control group (65.00％) (χ2 =14.602,P ＜ 0.01) ；the adverse reaction rate of the observation group was 8,33％,which was significantly lower than that of the control group(20.00％)(χ2 =11.368,P ＜ 0.01),Conclusion Mosapride combined with pancreatic kallikrein in thetreatment of DNB has better effect,and could significantly improve the clinical symptoms and quality of life of patients.So it should be promoted and applied.
ABSTRACT
OBJECTIVE To investigate the drug resistance of ESBLs-producing Escherichia coli and Klebsiella pneumoniae in local nosocomial infection,for guiding the clinical drug resistance. METHODS ATB analysis system was used for identification of bacteria,extra-susceptibility tests were detected by K-B method. RESULTS The isolation rate of ESBLs-producing E. coli and the K. pneumoniae was 29.9% and 30.8%,respectively. The drug susceptibility was indicated the resistance rate of ESBLs producing strains to antibacterial agents except imipenem was higher than that of non-ESBLs producing strains. CONCLUSIONS Detecting drug resistance of ESBLs producing strains is of important significance for guiding the clinical rational use of antibacterials and controling the epidemics.
ABSTRACT
OBJECTIVE To investigate the distribution and drug resistance status of extended-spectrum ?-lactamases producing(ESBLs) Klebsiella pneumoniae and to provide the basis for clinic anti-infective treatment.METHODS To use ATB-expression analyzer to identify the microbe.The drug susceptibility was tested with the K-B method and the ESBLs producing strains detected by diffusion confirmed test.RESULTS Among 137 strains of identified K.pneumoniae,34.3% of them(47 strains)produced ESBLs,and most had been shown in geriatrics ward.The drug resistance rate of ESBLs producing K.pneumoniae was higher than that in non-producing ESBLs one.So imipenem should be considered to be a preferred antibiotic when used on K.pneumoniae seriously infected cases.CONCLUSIONS The drug resistance of K.pneumoniae is a serious problem,we should pay attention on the status of ESBLs distribution,based on the susceptibility to choose the reasonable antibacterial to avoid the producing ESBLs bacteria spread out.
ABSTRACT
OBJECTIVE To investigate the drug resistance of ESBLs-producing Escherichia coli in community-acquired urinary tract infection for guiding the clinical drug-using.METHODS ATB-Expression analysis system was used for identification of bacteria,extra-susceptibility tests were detected by K-B method.RESULTS Totally 104 E.coli strains were detected,the isolation rate of ESBLs-producing E.coli was 13.5%,the resistant rates of E.coli were up to 70% to ampicillin,piperacillin and Co-trimoxazole,the resistant rate was up to 55% to ciprofloxacin and levofloxacin,and the susceptible rate was 100% to imipenem.CONCLUSIONS The E.coli is a main pathogen in community-acquired urinary tract infection,Its drug resistance is extremely severe.To enhance detecting drug resistance of pathogenic bacteria is of important significance for guiding the clinical rational drug-using and reducing drug-resistant strains.
ABSTRACT
OBJECTIVE:To investigate the condition of ESBLs produced by E.coli isolated from urinary tract and the drug resistance of ESBLs-producing E.coli.METHODS:The identification of bacteria was performed using ATB-Expression analysator(France);the susceptibility test was performed using K-B method,and ESBLs were detected using disc diffusion confirmatory test.RESULTS:The detection rate of ESBLs-producing E.coli was 31.8%.All(100%)of the 107 strains of ESBLs-producing E.coli were sensitive to imipenem,however,in which different degree of resistance to other antibiotics was noted.The resistance rate was significantly higher in ESBLs-producing strains than in non-ESBLs-producing strains.CON-CLUSION:In view of the high antibiotic resistance of ESBLs-producing E.coli,great importance should be attached to the detection of the ESBLs.Antibiotics should be used rationally based on the results of susceptibility test.
