Distribution and drug resistance of gram positive bacteria in hospital infection of elderly patients with cancer in Wuzhou / 国际检验医学杂志

ABSTRACT

Objective To master the distribution and drug resistance of gram positive bacteria in hospital infection of elderly cancer patients in Wuzhou area.Methods The clinical data of 136 cases of nosocomial infection with gram positive bacteria were summarized from May 2015 to April 2010 in Wuzhou area,and the distribution and drug resistance of pathogenic bacteria were summarized.Results Gram positive cocci Staphylococcus accounted for 64 strains(47.06％),45 strains of Streptococcus(33.09％),Enterococcus accounted for 27 (19.85 ％) strains of bacteria were gram positive cocci;pathogen mainly from throat swabs,sputum,drainage and blood,83.83％ of the total,Department sources to ICU,Radiology,Medical Oncology,the most common,accounting for 71.32 ％ of all,and the same group of other items had significant difference(P＜0.05);drug resistance,Staphylococcus to nitrofurantoin,tigecycline and vancomycin sensitivity was 100.00 ％,the other resistance was more than 55.00 ％;chain coccus of teicoplanin and vancomycin susceptibility 100.00 ％,more than 57.89 ％ other isolates were resistant to linezolid;Enterococcus faecalis sensitivity was 100.00％,which occurred in 1 cases (7.69％) resistant to vancomycin,other antimicrobial drug resistance was 54.55％ Above.Conclusion Elderly patients with tumors of gram positive cocci mainly come from respiratory tract infection ICU,interventional radiology is the hardest hit,there are serious drug resistance,vancomycin resistant Enterococcus faecalis in clinical,to strengthen the management of antimicrobial agents.
