Chicken resistance in Escherichia coli

30 strains of E. coli resistance to multiple drug resistance of species deposited (multiple drug resistance rate%) 4 (26.67) 5 (33.33) 6 (40.0o) 7 (46.67) 8 (53.33) l0 (6667) l2 (8000) Total deposition resistant strains (strains deposited% of total 10 (33.33) 2 (6.67) 2 (667) 8 (667) 4 (1333) 2 (6.67) 2 (6.67) 30 (100) 2.2 multi-drug resistant E. coli strains of Escherichia coli from chicken 3O l5 drugs on the multiple drug resistance in Table 2. can be seen from Table 2,[link widoczny dla zalogowanych], multiple drug resistance is serious, The average resistance of 8.5 kinds per plant, at least 4,[link widoczny dla zalogowanych], up to l2 species. multidrug resistance rate was 26.67% ~ 8O%. 3 to discuss the study in four districts of Jilin Province of chicken pathogenic Escherichia coli to do with the resistance of investigation and analysis of drug susceptibility test showed that 3O strains isolated resistant strains accounted for l00%, with four or more accounted for 33% of strains resistant to gentamicin, kanamycin, chloramphenicol, rifampin, tetracycline, ampicillin and penicillin resistance Dengjun with different strains exist. studies have shown that E. coli has a wide range of drug resistance. Analysis of the causes of this phenomenon may be: (1) normal E. coli adaptable to environmental pressures, more drug resistance; (2) clinical abuse of antibiotics,[link widoczny dla zalogowanych], especially penicillin and aminoglycoside antibiotics,[link widoczny dla zalogowanych], E. coli is a normal human gut flora, often under the pressure of selection of these antibiotics, resulting in more extensive drug resistance [1. multidrug resistance is colibacillosis new issues of drug control, some people try to understand the prevalence of E. coli resistance spectrum in a region to guide the clinical staff based drug screening, but this is only a defensive measure. E. coli resistance plasmid as constantly changing, so the investigation of drug resistance have certain timing constraints, from the current research trends, to eliminate the drug resistance plasmid is a fundamental solution to the problem of drug resistance of E. coli is a long-term strategic issues. 4 4.1 Conclusion of this experiment by 3O isolates from chickens from different parts of Jilin Province, pathogenic E. coli out of the anti-separation and extraction of plasmid resistance to ampicillin. plasmid extraction and analysis of master method, plasmids from epidemiological trends observed basis. 4.2 of the proposed through this study the drug resistance plasmid,[link widoczny dla zalogowanych], Jilin Province, parts of the treatment of colibacillosis in chickens provided a theoretical basis . colibacillosis of chicken in our province to ampicillin, penicillin, tetracycline, norfloxacin, erythromycin is not sensitive to amikacin, cefoperazone, cefazolin, kanamycin highly sensitive, followed by the celebration Big adriamycin, chloramphenicol, streptomycin and so on.
