  • Analysis of Distributing Characteristics and Drug Resistance of Escherichia Coli in Nosocomial Infection
    Journal of Nanhua University, 2020
    Co-Authors: Fei Lu


    Objective To investigate the distributions and drug resistance of Escherichia coli detected in our hospital. Methods Distributing conditions of 951 strains Escherichia coli among clinical samples isolated by routine Bacterium Culture in our hospital from Jan 2006 to Aug 2007 were studied retrospectively,drug resistances were explored by API half-automicroscan system. Results Separation rates of Escherichia coli in clinical samples such as urine,sputum,blood were higher,which were 27.2%,26.1% and 20.5% respectively.These strains were susceptible only to imipenem,meropenem and amikacin,and the rate of drug-resistance to other antibiotics were all more than 50.0%. Conclusions Escherichia coli has high resistance to a lot of antibiotics.Bacteria culturing and monitoring their resistance to antibiotics should be applied early in clinical jobs to guide reasonable drug prescription and control nosocomial infection effectively.

  • The Experimental Study of Antimicrobiologic Effect of Radiated Bone Incoporated with Lodophors
    Practical Clinical Medicine, 2020
    Co-Authors: Xiong Long


    Objective:To observe antimicrobiologic effect of radiated bone incoporated with iodophors.Methods:The bones collected from human and rabbit were rinsed with PBS and aseptic parceled,followed by be treated in supercleanlaminar flow room and stored as three groups below:Group A:the radiated allogeneic bone incorporated with iodophors;Group B:radiated allogeneic bone group;and Group C:deep frozen allogeneic bone group.They were assayed by Bacterium Culture and inhibiting bacteria in vitro.Results:There were bacterial growth in GroupsB and C.By contrast,bone grafts of Group A effectively inhibit growth of bacteria(P0.01).Conclusion:Radiated allogeneic bone incorporate with Iodophors should have good antimicrobiologic effect and it can avoid contamination.

  • Bacterial distribution and drug resistance in respiratory tract infection among geriatric patients.
    Chinese Journal of Nosocomiology, 2020
    Co-Authors: Chen Yuyu, Yan Xiang-jun


    OBJECTIVE To investigate the pathogens causing respiratory tract infection among the aged people,and analyze their drug resistance to antibiotics.METHODS The sputum samples of the old patients with respiratory tract infection were collected from Jan 2006 to Nov 2007,and the drug resistance of the pathogens isolated by routine Bacterium Culture were analyzed.RESULTS Totally 3867 pathogen strains were detected among the aged people with respiratory tract infection.The detected rate was 39.3%,from them the Gram-negative bacteric were 67.9% followed by the fungi,which accounted for 29.9%and Gram-positive cocci accounted for 2.2%.For example the Gram-negtive bacilli were resistante to cefuroxime gentamicin,trimethoprim/sulfa methoxazole and ciprofloxacin,but more susceptive to imipenem and meropenem.Staphylococcus were sensitive to vancomycin,minocycline and nitrofurantoin.CONCLUSION Gram-negative bacilli are the major pathogens causing respiratory tract infection among the old patients and highly resistant to a lot of antibiotics,but the fungal infection can not be ignored.The drug resistance monitoring to antibiotics and early bacterial culturing of the sputum samples are very important.

  • Main Pathogens in Urinary Tract Infections:Analysis of Distributing Characteristics and Drug Resistance
    Chinese Journal of Nosocomiology, 2020
    Co-Authors: Yan Xiang-jun


    OBJECTIVE To investigate the bacterial distribution and antibiotic resistance of main pathogens from urinary tract infection (UTI) in our hospital for the guidance of rational use of antibiotics. METHODS The antibiotic resistance of clinical pathogen isolates from urinary tract infection by routine Bacterium Culture from Jan 2006 to Dec 2007 were studied retrospectively. The extended spectrum β-lactamases (ESBLs) were detected out to the Gram-negative bacilli. RESULTS There were 722 strains of pathogens in the whole 2773 urinary samples with the isolating rate 26.0%. Most of the Urinary tract infections of patients were caused by Gram-negative bacilli (69.4%),then by Gram-positive cocci (16.3%) and fungi (14.3%). The most common pathogens in urinary tract infection were Escherichia coli (47.9%),Enterococcus faecais (7.9%),E. faecium (4.0%),Proteus mirabilis (3.9%),and Pseudomonas aeruginosa (3.5%). The Gram-negative bacilli were found to be sensitive to imipenem and meropenem,but highly resistant to the most other antibiotics,while P. mirabilis was susceptive to amikacin and cephalosporins. The Gram-positive cocci were more sensitive to nitrofuvantoin and vancomycin,but highly resistant to penicillin,oxacillin and SMT. CONCLUSIONS E. coli is still the primary urinary pathogen among patients,and highly resistant to a lot of antibiotics,We should carry out cultivation,isolation,and antimicrobial susceptibility testing as soon as possible to guide reasonable clinical drug therapy.
