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.

ABSTRACT
OBJECTIVE To study the distributive characteristics of the pathogens of the bacterial infectious diseases in Wuzhou,and to provide the basis for prevention and therapy of the infectious diseases.METHODS The VITEK-ATB system,BDPhoenix100 system,API system and CHROMagar were used to appraise the pathogens,which were from the bring up of doubtful infectious disease specimens.RESULTS The positive rate of 4 878 pathogenic test was 32.10%.The Gram-negative bacilli were the major(63.96%) from the 1 623 strains of pathogens isolated.The main composition of pathogen spectrum was Escherichia coli,Klebsiella pneumoniae,Staphylococcus aureus,Pseudomonas aeruginosa,Acinetobacter baumannii,Candida albicans,Enterococcus faecalis,Staphylococcus haemolyticus,Enterobacter cloacae,and Staphylococcus epidermidis.The distribution of main pathogens had different characteristics in different season and different infectious diseases.CONCLUSIONS Strengthening the test of pathogens in the doubtful infectious diseases and understanding the characteristics of local pathogen spectrum and the transitional current of infections in time,significantly influence on prevention and therapy of the infectious diseases.
