Samples were collected from 38 H. pylori infected patients with duodenal ulcers from the Gastroenterology Service of the “Hospital Vargas”, Caracas, Venezuela (2009-2011) and were processed by the E-test method. The 94.8% isolates were sensitive to clarithromycin and erythromycin with MIC values of <0.5 mg/L and < 2 mg/L respectively. The 92.2% of the strains had a tetracycline MIC under 1 mg/L and 37% of the sensitive H. pylori strains had a metronidazole MIC of <8 mg/L. Metronidazole resistance occurred in 24/38 strains (63.1%), while resistance to erythromycin was found in 2/38 strains (5.2%), clarithromycin in 2/38 (5.2%), and tetracycline in 3/38 (7.8%) of the isolates. None of the strains was found to be resistant to amoxicillin. We observed 6/38 (15.8%) multi-drug resistance of H. pylori isolates in different combinations. 2017 otro 1317-973X https://www.redalyc.org/articulo.oa?id=199454946009 en http://www.redalyc.org/revista.oa?id=1994 Revista de la Sociedad Venezolana de Microbiología application/pdf Sociedad Venezolana de Microbiología Revista de la Sociedad Venezolana de Microbiología (República Bolivariana de Venezuela) Num.2 Vol.37 |
