| Abstract: | Different microorganisms can cause intraperitoneal infection. This study was to distinguish different microbial infections by urine analysis. Rats were intraperitoneally injected with Escherichia coli, Staphylococcus aureus, and Candida albicans, separately. Urine samples were collected from rats at 0, 12, 36 and 72 h after infection. Urinary proteins were profiled using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Compared with the control (without infection), a total of 69 differential proteins were identified in rats injected with E. coli. A total of 31 differences proteins were identified in rats injected with S. aureus. A total of 38 differential proteins were identified in rats injected with C. albicans. Urine proteome was different when rats were infected by different microorganisms, suggesting that urine may have the potential for differential diagnosis of different intraperitoneal infections. |
