Helicobacter pylori (H. pylori) is a microaerophilic gram-negative bacillus that colonizes the gastric mucosa. It infects more than half the world’s population, making it the most common bacterial infection. The prevalence of infection and associated diseases is high in developing countries. The recommended treatment for its eradication is triple therapy; however, its efficacy has decreased due to the lack of knowledge of the bacterial susceptibility pattern among the medical staff and the emergence of resistant strains. H. pylori susceptibility is associated with the bacteria’s ability to adapt to hostile environments and the use of antibiotics. In Colombia, it has been reported that H. pylori is resistant to amoxicillin, metronidazole, clarithromycin, furazolidone, levofloxacin, and tetracycline. Studies on the susceptibility pattern have determined that the frequency of H. pylori susceptibility is variable and demonstrate the lack of data in most of the Colombian territory. With this in mind, the objective of this review is to describe the percentage of resistance to amoxicillin, metronidazole, clarithromycin, furazolidone, levofloxacin and tetracycline, which are used for the treatment of H. pylori infection, according to studies conducted in Colombia.
