Brief summary

The goal of this observational study is to evaluate the safety of sulbactam-durlobactam, as well as the risk of hypersensitivity reactions (including anaphylaxis) in participants with Acinetobacter baumannii-calcoaceticus complex infection. Participants will be followed for approximately 28 days in order to collect safety and reaction data.

Inclusion criteria

* Participant is ≥18 years old at the time of written informed consent and is hospitalized. * Participant has provided the written informed consent. If a participant is unable to provide written informed consent due to their medical condition, the participant's legally authorized representative may consent on behalf of the participant, or the decision can be made according to the procedure permitted by local law and institutional standard operating procedures (SOPs). * Participant has a proven or strongly suspected diagnosis of an infection caused by susceptible ABC isolates, based on investigator's clinical judgment. * Participant initiates treatment with SUL-DUR per routine clinical care. Participants who receive SUL-DUR within 24 hours prior to enrollment are also eligible to participate. The decision to treat the participant with SUL-DUR is made prior to and independently of study participation. * The participant has an expected survival of \>48 hours at the time of written informed consent.

Exclusion criteria

* A history of significant hypersensitivity or allergic reaction to any β-lactam, or any contraindication to the use of β-lactam antibiotics
