ClarithromyCin resistanCe among Helicobacter
The aims of this study were to assess primary resistance of H. pylori strains isolated from adult patients of Ilam, Iran to antibacterial agents (amoxicillin, clarithromycin, metronidazole and tetracycline) and detection of clarithromycin, azithromycin, clarithromycin, metronidazole and tetracycline resistance by disc diffusion. Fifty biopsies were taken from gastric mucosa of the antrum and bo...
متن کاملHelicobacter pylori antibiotic resistance in Brazil: clarithromycin is still a good option.
CONTEXT The antibiotic susceptibility is the cornerstone for the eradication therapies of Helicobacter pylori. OBJECTIVES To evaluate the prevalence of primary resistance of H. pylori was evaluated in an urban Brazilian population. METHODS H. pylori isolates were obtained from patients submitted to an upper gastrointestinal endoscopy for the evaluation of dyspeptic symptoms. Biopsies from a...
متن کاملEvolution of Antibiotic Resistance without Antibiotic Exposure
Antibiotic use is the main driver in the emergence of antibiotic resistance. Another unexplored possibility is that resistance evolves coincidentally in response to other selective pressures. We show that selection in the absence of antibiotics can coselect for decreased susceptibility to several antibiotics. Thus, genetic adaptation of bacteria to natural environments may drive resistance evol...
متن کاملAntibiotic Resistance
Antibiotic resistance is an ongoing evolutionary process that has been the concern of infectious disease specialists since antibiotic use gained popularity. Antibiotic resistance is not a concern of the public as reflected by their desire for antibiotics whenever illness occurs. Patients can and do pressure their physicians for antibiotics ; 12 million antibiotic prescriptions were filled for u...

are resistant to one of the first-line drugs (rifampicin, isoniazid, ethambutol, streptomycin).5 Resistance is emerging due to the increasing exposure of microorganisms to antimicrobial agents. Exposure of microbes to antimicrobials tempt them to develop strategies to survive in the hostile environment and become resistant. Pressure on the bacteria to mutate and become “hardy” develops due to (...
