The bacteria are able to sense acidic medium pH and stimulate trafficking of cytoplasmic urease and its accessory proteins to the proton-gated urea channel, UreI, in the inner membrane. The breakdown of urea into carbon dioxide and ammonia buffers the periplasm and cytoplasm to within the pH range o

For those bacteria that come in contact with animals an important component of the Gram-negative outer membrane is lipopolysaccharide (LPS), a complex molecule not found elsewhere in nature. LPS, also termed endotoxin, represents the main surface antigen (O-anti
