Hohe Auflösung Elektronenmikroskopie der<em> Helicobacter pylori</em> Cag Typ IV-Sekretionssystem Pili Produziert in variierenden Bedingungen von Iron Verfügbarkeit
Here we describe a method to visualize the oncogenic bacterial organelle known as the Cag Type IV Secretion System (Cag-T4SS). We find that the Cag-T4SS is differentially produced on the surface of H. pylori in response to varying conditions of iron availability.
