ABSTRACT

Objetivo. Determinación de la susceptibilidad a metronidazol en aislamientos de Helicobacter pylori obtenidos de pacientes colombianos durante el periodo de abril de 2006 a marzo de 2007. Materiales y métodos. Se les realizó la prueba de susceptibilidad a metronidazol por el método de E test a 53 aislamientos de H. pylori obtenidos por cultivo de biopsias gástricas procedentes de pacientes adultos a quienes se les practicó una endoscopia de vías digestivas altas. Resultados. Se obtuvieron 53 aislamientos de H. pylori provenientes de 26 hombres y 27 mujeres. El método de susceptibilidad antimicrobiana E test demostró que el 72% de los aislamientos de H. pylori fueron resistentes a metronidazol. Conclusiones. La resistencia de H. pylori a MTZ en la actualidad continúa siendo alta y es comparable a la publicada hace 10 años (72% y 84% respectivamente). Por ser mayor del 40% sería recomendable no utilizar este antimicrobiano en los esquemas de erradicación en Colombia.


Objective. To determine susceptibility to Metronidazole when isolates Helicobacter pylori obtained from Colombian patients during the period April 2006 to March 2007. Materials and methods. The susceptibility test to Metronidazole was realized using the E Test Method to 53 isolates of H. pylori obtained through cultures of gastric biopsies, coming from adult patients to whom endoscopies of upper gastrointestinal tracts were practiced. Results. Fifty-three isolates of H. pylori were obtained from 26 men and 27 women. The antimicrobial susceptibility E Test method showed that 72% of the isolates of H. pylori were resistant to Metronidazole. Conclusion. Resistance of H. pylori to MTZ currently continues being high and is comparable to the one published 10 years ago (73% and 84% respectively). For being greater than 40%, it is recommended not to use this antimicrobial agent in the Colombian eradication programs.
