Disclosed are methods and compositions related to polypeptides comprising a fusion of the needle tip protein and translocator protein of a type III secretion apparatus (T3SA) from a type III secretion system (T3SS) of a Gram negative bacteria. Disclosed herein are fusion polypeptides comprising a fusion of a needle tip protein, such as, Bsp22, LcrV, BipD, PcrV, CT053, or CT668, or anantigenic fragment thereof; and a translocator protein, such as, BopB, YopB, BipB, PopB, CopB, or CopB2, or anantigenic fragment thereof from a Type III secretion system (T3SS) of a Gram negative bacteria, such as, Bordetella, Burkholderia, Chlamydia, Pseudomonas, Vibrio , or Yersinia. |
