antibiotic susceptibility patterns of helicobacter pylori strains isolated from northeastern mexico.	there are reports of increased antibiotic resistance rates in helicobacter pylori strains around the world. the aim of this study was to determine the susceptibility patterns in h. pylori strains isolated in monterrey, mexico. we studied 62 strains isolated from the same number of symptomatic adult patients. metronidazole (mtz), clarithromycin (cla), amoxicillin (amx) and tetracycline (tet) were tested by the e-test method. we observed that 37.1% of the strains were resistant to mtz (mic > or = ...	2002	12420850
comparison of helicobacter pylori prevalence in symptomatic patients in northeastern mexico with the rest of the country: its association with gastrointestinal disease.	prevalence of helicobacter pylori varies among different geographic regions. the aim of this study was to assess h. pylori prevalence in symptomatic patients in northeastern mexico and its possible association of h. pylori with disease.	2003	12604377
role of p53 codon 72 polymorphism in the risk of development of distal gastric cancer.	mutations in the codon 72 of exon 4 in the p53 gene have been associated with higher risk in the development of several types of cancer. this polymorphism occurs with two alleles encoding either arginine (cgc) or proline (ccc). the aim of this study was to assess the role of the codon 72 polymorphism of p53 in the risk for the development of distal gastric cancer (gc) in a mexican population.	2005	15841715
