*Identification was performed by use of the API Coryne strip system (bioMérieux, Durham, NC, USA), MALDI-TOF-MS (matrix-assisted laser desorption–ionization time-of-flight mass spectroscopy) (Bruker Daltonics; Fremont, CA, USA), and gene sequencing. Percentages after the API identification refer to confidence limits. Percentages after the gene sequencing results refer to percentage identities with a reference strain (4). MIT, Massachusetts Institute of Technology; CDC, Centers for Disease Control and Prevention. †2.000–2.299, secure genus identification, probable species identification; 2.300–3.000, highly probable species identification (4). ‡The API code generated at MIT was 0101320, interpreted as C. pseudotuberculosis (99.5%).
