Abstract Two strains of suspected Salmonella spp were detected from fresh goose and duck samples by the selective pre-enrichment method according to the GB 4789.4?2010. However, the microorganism was identified as Pseudomonas aeruginosa by ATB biochemical identification and matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF-MS). By analyzing the biochemical profiles of the two Pseudomonas aeruginosa strains and Salmonella spp, we found that the results of ornithine decarboxylase, arginine dihydrolase and L-arabinose tests were identically positive while the other biochemical results varied widely. Besides, the footprints of mass spectrometric peak of Pseudomonas aeruginosa and Salmonella enteritidis were significantly different. Drug resistance results showed that most of the antibiotics examined except ciprofloxacin, gentamicin and streptomycin could not inhibit Pseudomonas aeruginosa.
