Septic Shock Secondary to Pyelonephritis

A 55-year-old male presented to the hospital from an outside facility with sepsis secondary to pyelonephritis.


This case highlights not only T2Bacteria’s ability of rapid identification but also the capability to detect the causative organism in the presence of antibiotics. The patient, in this case, received a dose of ceftriaxone and azithromycin before the blood cultures and T2Bacteria were drawn. Bloodstream infection was missed by blood culture but was identified with rapid detection provided by the T2Bacteria Panel. The use of T2Bacteria, in this case, allowed an early confirmation of effective antibiotic therapy.


Positive for P. aeruginosa

An 81-year-old patient with a complicated medical history was admitted to the hospital for a tracheoesophageal fistula repair.


This case highlights the benefit of the T2Bacteria Panel’s turnaround time for species identification. Tigecycline has been associated with high rates of gastrointestinal adverse events such as nausea and vomiting and does not provide adequate coverage of P. aeruginosa. The rapid result provided by T2Bacteria allowed for discontinuation of Tigecycline after only one dose. Additionally, amikacin was added as an antimicrobial known to be effective against P. aeruginosa based on the institution’s antibiogram.


Detection of Polymicrobial Infections Using T2Bacteria

The patient presented to the emergency department with flu-like symptoms


This case highlights the ability of the T2Bacteria® Panel to provide rapid species identification of causative pathogens in sepsis cases. It examines clinical challenges with current methods, including delayed blood culture growth, as well as polymicrobial infections. A rapid T2Bacteria result could have allowed for more informed treatment decisions, including earlier initiation of antibiotic therapy and earlier admission to the hospital.
