ABSTRACT
Quinolone antibiotics have been commonly used to treat cases of multiple antibiotic resistance. Unfortunately, quinolone antibiotics have so much been resisted by infectious bacterial agents. This study aimed to evaluate the susceptibility of some clinical isolates of E. coli to some commonly used quinolone antibiotics and the determination of the plasmid-encoded quinolone resistance genes. Our results showed the plasmid quinolone-resistance genes in the following prevalence: qnr genes: qnr S (71.4 %); qnr B (15.4 %); qnr S and B (12.1 %); aac (6) lb-cr (4 %); Efflux genes: oqxA (7.7 %); oqxB (25.3 %); qepA (12.1 %); oqxA and oqxB (5.5 %). We conclude that there is a high frequency of Plasmid-mediated quinolone resistance genes in Escherichia coli isolates from clinical samples in South-Eastern Nigeria. These could be responsible for the high incidence of quinolone resistance reported in Enugu. There is a need for whole-genome sequencing to map out all resistance genes.
ABSTRACT
OBJECTIVE:To evaluate the efficacy and safety of Qianlie shutong capsule combined with Quinolone antibiotics in the treatment of chronic prostatitis, and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,Cochrane Library,CBM,CJFD,VIP Database and Wanfang Database,randomized clinical trials(RCT)about the efficacy and safety of Qianlie shutong capsule combined with Quinolone antibiotics(test group)versus only Quinolone antibiot-ics(control group)in the treatment of chronic prostatitis were collected,Meta-analysis was performed by using Rev Man 5.3 soft-ware after data extracting and quality evaluating by modified Jadad. RESULTS:Totally 16 RCTs were enrolled,involving 2 368 pa-tients. Results of Meta-analysis showed the total effective rate [RR=1.56,95% CI(1.29,1.88),P<0.001],US National Institutes of Health Chronic Prostatitis Symptom Index scores(NIH-CPSI scores)[MD=-6.97,95% CI(-8.67,-5.26),P<0.001],pain symptom scores[MD=-3.18,95%CI(-3.92,-2.44),P<0.001)],voiding dysfunction scores [MD=-1.62,95%CI(-1.85,-1.38), P<0.001],life quality scores[MD=-2.16,95% CI(-2.89,-1.43),P<0.001],EPS leukocyte count [MD=-8.90,95% CI (-11.79,-6.02),P<0.001] and recurrence rate[RR=0.22,95%CI(0.12,0.42),P<0.001] in test group were significantly better than control group,there were statistically significant differences between 2 groups;and there was no significant difference in the incidence of adverse reactions between 2 groups [RR=0.49,95%CI(0.11,2.13),P=0.34]. CONCLUSIONS:The efficacy of Qian-lie shutong capsule combined with Quinolone antibiotics is better than only Qianlie shutong capsule or Quinolone antibiotics in the treatment of chronic prostatitis,with similar safety.
ABSTRACT
Objective To establish a real-time fluorescence PCR method to detect the drug resistance genes of pathogenic Campylobacter jejunum in human stool samples,and investigate the relationship between quinoloneantibiotic resistance and the related genes in Campylobacter jejuni .Methods According to the gyrA and gyrB gene sequences that related with the fluoroquinolone resistance in Campylobacter jejuni ,the primers of the PCR method was designed and synthesized.A rapid real-time fluorescence PCR method to detect the drug resistance genes in Campylobacter jejuni samples was established,and the optimum reaction system and conditions were screened through an optimized approach.The developed method was com-pared with the classical drug susceptibility assay.Results It was found in the compared results that,there were 8 inconsis-tent strains of Campylobacter jejuni ,2 of the 8 strains were drug sensitive but contented the drug resistance gene,while 6 strains were drug resistant but had no drug resistant gene.Conclusion The established method can be applied to detect the drug resistance relative genes of gyrA and gyrB in Campylobacter jejuni .There was some correlation between the drug re-sistance representation and its genotype,but this point requires further studies.
ABSTRACT
BACKGROUND/AIMS: For the investigation of the efficacy and safety of intravenous levofloxacin, The clinical study was carrried out in 30 patients with abdominal operation, especially in hepatobiliary and pancreatic division. METHODS: Randomly chosen patients received intravenous levofloxacin (250mg bid) for only 7 days. Clinical and microbiological evaluation were conducted on the day of starting and finishing levofloxacin treatmeat except for the case of combined use of antibiotics. RESULTS: The most commonly isolated organism was staphylococcus aureus(33%, 3/9). The overall bacteriologic eradication rate was 67%, (6/9) with clinical success rate was 96%(29/30), There were no significant dverse effects to stop the administration of the drug. CONCLUSION: These results suggest that intravenous levofloxacin is effective and safe antibiotics in the fields management of abdominal operation especially in hepatobiliary and pancreas surgery.
