For instance, Bartonella, another intracellular parasite inducing long lasting infections in mammals, shares with Brucella the chemical and biological characteristics of its lipid A, core oligosaccharide, major fatty acids, low number of BLPs, putative enzymes to built ornithine-lipids, and flagella not recognized by TLR5 [62], [65], [69], [70]. The gene discussed is TLR5; the disease is infection.
