T2Bacteria enabled the detection of a polymicrobial infection as well as the detection of Enterococcus faecium in a patient where cultures remained negative. Rapid species identification lead to targeted therapy and eventual discharge.

Evaluation and Treatment
The patient was admitted to the hospital eight days after the onset of symptoms and then admitted to the ICU with COVID-19 and respiratory failure. The patient was mechanically ventilated.
Weaning was complicated due to ventilator-associated pneumonia.
The T2Bacteria Panel was positive for Staphylococcus aureus and Escherichia coli, and targeted therapy was initiated before culture results were returned.
A bronchoalveolar lavage sample was also positive for Staphylococcus aureus and Escherichia coli.
10 days later, the patient developed septic shock from an unknown source. Several blood, bronchoalveolar, and urine cultures were taken, but no growth occurred.
Another T2Bacteria Panel was run and was positive for Enterococcus faecium, leading to targeted therapy. A transesophageal echocardiogram revealed endocarditis of the native aortic valve.
After 42 days in the ICU, the patient was discharged to a rehabilitation facility.
