[Abstract]:Objective: blood flow infection is characterized by severe clinical symptoms and high mortality. The drug resistance characteristics of Escherichia coli in the second affiliated hospital of Kunming Medical University and the composition of drug resistance gene were detected and the distribution was analyzed. To investigate the clinical epidemiology of ESBLs Escherichia coli in community and hospital, and to analyze the risk factors of blood stream infection caused by ESBLs producing Escherichia coli. Methods: 181 strains of Escherichia coli from January to December 2014 in the second affiliated Hospital of Kunming Medical University were collected, including 88 strains of community infection and 93 strains of nosocomial infection. The bacteria identification and drug sensitivity test were carried out by using the Merier VITEK-2 Compact instrument in France, the ESBLs producing Escherichia coli was detected by K-B disk diffusion method, and the CTX, TEM and SHV genes of ESBLs positive strains were amplified by PCR to determine the genotyping. The risk factors of blood flow infection were analyzed by SP13.0 software. Results: the drug resistance rates of 1181 blood stream infected Escherichia coli strains were less than 10%, including cefoperazone / sulbactam, piperacillin / tazobactam, etapenem, imipenem, amikacin, etc. The drug resistance rate of nosocomial infection strains was higher than that of community infection strains. 47 strains of ESBLs producing Escherichia coli were detected from community blood flow infection, the positive rate was 53.4%, and 68 strains from hospital blood stream infection produced ESBLs Escherichia coli, the positive rate was 73.1%. Community infection was significantly lower than nosocomial infection (P0. 006). In 2115 strains of ESBLs producing Escherichia coli, 95% of the CTX genes were amplified, of which CTX-M-1 accounted for 35% and CTX-M-9 accounted for 63%. The TEM type was 53% and the SHV type was 15%. There were 58 strains (50.4%) carrying two genes and 13 strains (11.3.3%) carrying three genes simultaneously. ICU, urology and general surgery were the first three departments in the detection rate of ESBLs Escherichia coli infection in the whole hospital. Among them, 57.4% were community infection, 64.7.6 clinical risk factors were observed in hospital infection, and there were significant differences among the four indexes, which were whether or not they were admitted to medical institutions in the last 3 months. Do you use antibiotics, catheters, and mechanical ventilation? Conclusion: 1. The drug resistance rate of Escherichia coli in community blood stream infection of the second affiliated hospital of Kunming Medical University was generally lower than that of nosocomial infection. 2. The prevalent genotype of ESBLs producing Escherichia coli was CTX, followed by TEM and SHV. The positive rate of ESBLs producing Escherichia coli in patients with blood flow infection in urology and general surgery was higher than that in other departments. The infection of ESBLs might be related to the medical institutions, antibiotics use and invasive operation and so on. Therefore, strengthening hospital infection control, standardizing invasive operation, improving staff's aseptic consciousness and hand hygiene, rational use of antibiotics, and strengthening infection monitoring in ICU, urology ward are effective measures to control bacterial drug resistance.
