PATHOGENS

• Among the most common infections encountered in hospital and clinical practice, resistant strains are increasingly encountered:
  
  • Enterobacterales
  • Pseudomonas aeruginosa
  • Acinetobacter sp.
• Less common:
  
  • MSSA or MRSA
    
    • Most due to invasion of the urinary tract (secondary to catheters, stents)
    • Consider presentations of staphylococcal bacteremia with findings of S. aureus in urine.
  • Enterococcus spp. (including VRE)
  • Candida spp.
  • Fastidious organisms are possible.
• Infections may be polymicrobial, especially if chronic urinary catheters or stents are present.
