E.coli and Staph saprophyticus?
I'm having trouble with my internet, but answering coming soon, I promise!
Escherichia coli, enterococci, Pseudomonas aeruginosa, candida, and Klebsiella pneumoniae.
hi! my internet is still giving me grief, but briefly, the diagnosis is emphysematous pyelonephritis and the most common organisms are E coli and Klebsiella. :)

The imaging shows abnormal collection of air around the right kidney. This is emphysematous pyelonephritis, a gas-producing necrotizing infection of the renal parenchyma or perirenal tissue, usually due to E.coli or Klebsiella (rarely Candida).
