I had also the same problem, and Birboin method and Kado and Liu didn't work
well with Acinetobacter spp.
I used the Hartstein et al method that worked well, with some modifications.
I don´t have here the technique I used because I´m Home. But here is the
reference: Hartstein et al , 1990, Infect: Control. Hosp. Epidemiol.
11:531-538.
Try to use cell cultures on late exponential phase and higher volumes. If
you want the protocol, call me for my mail in the University:

Good luck
