Task: Answer Verification
Input (English): Question: Does mannose-binding lectin deficiency increase the prevalence of Helicobacter pylori seropositivity?
Answer: Mannose-binding lectin deficiency does not increase the risk of H. pylori infection. The finding in one population that greater mannose-binding lectin activity might predispose to infection, suggests that this study should be repeated in other large cohorts of normal subjects.
Output (English): no
