Bilophila wadsworthia is a Gram-negative, obligately anaerobic, catalase-positive, bile-resistant, and asaccharolytic bacillus. Approximately 75% of B. wadsworthia strains are urease positive. B. wadsworthia is linked to various diseases and is not well known due to frequent misidentification of the bacteria, and the National Center for Biotechnology Information is including it the phylum of Proteobacteria.[1] The two unique characteristics of B. wadsworthia are the utilisation of the sulfated amino acid taurine in the production of hydrogen sulfide and the rapid catalase reaction. This bacterium is susceptible to the β-lactam antibiotics imipenem, cefoxitin, and ticarcillin.
