This study examined the associations of operator routine procedural exposure and children’s residential setting (urban vs. rural) with quality indicators across three stages—diagnostic attribution, operational execution, and long-term retention—in a pit-and-fissure sealant progra...

Population heterogeneity in Helicobacter pylori PMSS1 shapes variable mouse infectivity: derivation of the homogeneous reference strain PMSS2

ABSTRACT Experimental infection models are widely used to investigate host–microbe interactions, often under the assumption that bacterial populations are genetically uniform. Here, we examined population heterogeneity in the widely used Helicobacter pylori strain PMSS1 and its r...
