Female patient presents with clinical symptoms consistent with pyelonephritis and her urine culture grows the following: 
What is the mechanism of resistance of this E. cloacae?
Female patient presents with clinical symptoms consistent with a UTI and she has the following urine culture:
What is the mechanism of resistance of this E. coli?
Patient presented with fever and RUQ pain. He was found to have a liver abscess which has now been drained. Cultures grew the following:
What is the mechanism of resistance of this K. pneumoniae?
Pt presented w/abd pain & was found to have diverticulitis w/ abscess which was drained. Cx grew K. pneumoniae. Pt travels to India frequently.
Extended panel: Cefiderocol-S.
Exploratory: In vitro synergy of ceftazidime/avibactam and Aztreonam using Agar-Etest methods-S.

What is the mechanism of resistance of this K.pneumoniae?
Patient is in the ICU s/p MVA and is intubated for airway protection. He develops signs of pneumonia and a CXR shows alveolar infiltrates on the RLL. BAL culture grows the following Pseudomonas aeruginosa:
Which mechanism of resistance is likely expressed in this PSAR isolate?
