腫瘤患者醫(yī)院感染革蘭陽性球菌的分布與耐藥性分析
[Abstract]:Objective to investigate the distribution of gram positive cocci in nosocomial infection of cancer patients and their resistance to common antibiotics, and to provide a basis for clinical rational use of antibiotics. Methods 172 cases of gram-positive cocci from the cancer prevention and control center of Zhongshan University in 2014 were investigated. All the specimens were used in French biological mailler. The VITEK-32 microbial identification system was used to identify the strains and analyze the drug resistance. The basic situation of the infected people, the distribution of the section, the distribution of the specimens and the drug resistance were analyzed with the software of EXCEL8.0 and WHONET5.4. The results showed that 172 strains of gram-positive cocci were isolated from the hospital infected patients, mainly from swabs, sputum and drainage. The higher isolation rate of the staphylococci was the radiotherapy department, ICU and the chest department, gram-positive cocci were mainly Streptococcus and Staphylococcus, 43.6% and 40.1%, respectively, the resistance rate of Streptococcus to erythromycin and sulfamethoxazole / trimethoprim was 85%, and the susceptibility rate to linezolid and vancomycin was 100%, and Enterococcus to clindamycin and erythromycin. The susceptibility rate of teicoplanin and tegacycline was 100%, and 1 strains of vancomycin resistant Enterococcus (VRE) were found. The resistance of Staphylococcus to penicillin and zoxicillin was 85%, and the susceptibility rate of linezolid and tenacycline was 100%; methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative grapes were found. The detection rates of staphylococci (MRCNS) were 60% and 89.8%. respectively. Conclusion the main specimens of gram positive cocci from hospital infection were mainly from the respiratory tract, mainly Streptococcus and Staphylococcus, the drug resistance was serious, the multidrug resistance was obvious, and the VRE was found. The clinical should be vigilant.
