Bordetella trematum in chronic ulcers: report on two cases and review of the literature.

We report on two new cases Bordetella trematum in chronic ulcers. Literature shows that this species is infrequently isolated from clinical samples. Only a few cases have been reported so far. B. trematum may be underdiagnosed because of its problematic identification. Today, MALDI-TOF MS allows for an accurate discrimination of these bacteria. Overall, B. trematum was typically associated with severe skin and soft tissue infections, particularly in diabetic patients. The intrinsic resistance to some antibiotics commonly used to treat these infections makes the isolation of B. trematum significant.
