Core Tip

Core Tip: In recent years, associations have been found between virulence markers of Helicobacter pylori and gastrointestinal disorders. In parallel, several physicians in northern Israel noted a higher treatment failure rate among Arab patients compared to Jewish patients. This work found a significant correlation between disease severity and patient ethnicity (P = 0.002). Further, a higher level of urease activity was associated with isolates originating from the Jewish population. Moreover, higher urease activity levels were measured among CagA-/s1m1 and CagA-/s2m2 isolates. These findings are expected to advance personalization of treatment to specific strains based on their virulence factors.
