Clinical isolates of ST131 OXA-244-positive , Italy, December 2022 to July 2023.

The dissemination of carbapenemase-producing although still at low level, should be continuously monitored. OXA-244 is emerging in Europe, mainly in . In Italy, this carbapenemase was reported from an environmental river sample in 2019. We report clinical isolates of OXA-244-producing ST131 in four patients admitted to an acute care hospital in Pavia, Italy. The association of this difficult-to-detect determinant with a globally circulating high-risk clone, ST131 is of clinical relevance.
