Trimeric autotransporter adhesins (TAAs) are important virulence factors and are widely present in various pathogenic Gram-negative bacteria. TAA-expressing bacteria cause a wide spectrum of human diseases, such as cat scratch disease ( Bartonella henselae ), enterocolitis ( Yersinia enterocolitica ), meningitis ( Neisseria meningitis ), and bloodstream infections (multidrug-resistant Acinetobacter baumannii ).
