There are speccersna outer membrane protens thathave beestuded extensvely and characterzed as nhbtors of specc bologcal processes that advertise the survval ofersna speces wththehost.Speccally, the protensopE,h, J, M, O, P, and dsrupt cytoskeletal dynamcs, nhbt nnate and acqured mmune functons, and advertise apoptoss.The outer
