title: What is the role of lipid A in the development of pyelonephritis? A hypothesis.
abstract: From the studies of Westenfelder et al. and our own studies of the presence of lipid A antibodies in the upper and lower urinary tract infections, it can be concluded that chronic pyelonephritis is a lipid A induced disease. This hypothesis is based on the distinct statistically different antibody production in upper urinary tract infection in contrast to lower urinary tract infection, the persistence of lipid A in renal tissue, as well as the induction of lipid A nephritis in puppies. These observations should be considered in future studies to proceed in the clarification of these diseases.
