Shotgun proteomic profiling of Yersinia ruckeri strains

ABSTRACT: Project goal is to identify proteomic profiles of Yersinia ruckeri, the causative agent of enteric redmouth disease in fish. Four strains (SP-05, CSF007-82, 7959-11 and YRNC-10) of Y. ruckeri were isolated from disease rainbow trout, Oncorhynchus mykiss. Strains, SP-05 and CSF007-82, belong to serotype 1 and biotype 1 (motile and lipase positive), while strains 7959-11 and YRNC-10 belong to serotype 1 and biotype 2 (non-motile and lipase negative) and belong to serotype 1. A single colony of each strain was inoculated into tryptic soy broth (Casein peptone, dipotassium hydrogen phosphate, glucose, sodium chloride, soya peptone, Sigma) and grown at 22 °C with shaking (150 rpm). These starter cultures were then diluted with fresh sterile tryptic soy broth to an optical density (OD 600) of 0.10 ± 0.05. Five hundred microlitres of the diluted starter cultures were inoculated in duplicates, into 25 ml of tryptic soy broth. Cultures were grown overnight at 22 °C with shaking (150 rpm) until the late log phase. Cells were harvested by centrifugation, then washed three times with PBS.
