  1. The protein profiles produced by A. baumannii grown in the presence of macrophages were performed using iTRAQ reagents and LC-MS/MS. Differential expression was defined by a relative abundance ratio >1.5 and <0.5
  2. aSecretion prediction are based on (SignalP 4.1 (http://www.cbs.dtu.dk/services/SignalP/), Phobius (http://phobius.sbc.su.se/), PrediSi (http://www.predisi.de/), TatP 1.0 (www.cbs.dtu.dk/services/TatP-1.0), Tatfind 1.4 (http://signalfind.org/tatfind.html), SecretomeP 2.0 (www.cbs.dtu.dk/services/SecretomeP), TMHMM (http://www.cbs.dtu.dk/services/TMHMM/), DAS-TMfilter (http://www.enzim.hu/DAS/DAS.html), LipoP 1.0 (www.cbs.dtu.dk/services/LipoP), DOLOP (http://www.mrc-lmb.cam.ac.uk/genomes/dolop/), and LIPO (http://services.cbu.uib.no/tools/lipo))
  3. bAverage relative protein expression level ratio in sample and control, with the standard deviation in parentheses, quantified by Protein Pilot 4.0 software (ABSciex).
  4. cDetermined by Student’s t test. Values of less than 0.05 are considered significant
