Bartonella henselae expresses pill phenotypically similar to type 4 pi
li. B. henselae pilus expression undergoes phase variation with multip
le passages. Low-passage-number, piliated B. henselae adhered to and i
nvaded HEp-2 cells to a greater extent than did multiply passaged B. h
enselae with reduced pilus expression. Pill may be a pathogenic determ
inant for Bartonella species.
