full_question: A staining mixture of Alcian yellow and toluidine blue is used to test for the presence of this organism. This organism secretes a protein that is phosphorylated by Src kinases at its EPIYA sites. That protein secreted by this organism interacts with Crk adaptors of the host cells, causing the host cells to elongate, a morphological change called the hummingbird phenotype. This organism is present in over 90% of patients with MALT lymphomas. This organism produces vacuolating cytotoxin A, and its pathogenicity is based on the virulence factor CagA. This organism can be detected using a urea breath test and its infections are often treated using a "triple therapy" consisting of one proton pump inhibitor and two antibiotics. This organism's role as the causative agent of a certain condition was studied by Barry Marshall, who drank a broth containing colonies of this organism. This organism burrows into the epithelium lining the stomach to avoid the low pH environment within. For 10 points, name this bacterium that causes peptic ulcers and gastritis.
