Final answer:
Piperacillin+Tazobactam or Zosyn is useful for treating serious infections caused by gram negative aerobic bacilli and mixed aerobic-anaerobic infections.
Step-by-step explanation:
Piperacillin+Tazobactam or Zosyn is useful for treating serious infections caused by gram negative aerobic bacilli and mixed aerobic-anaerobic infections.
Gram-negative aerobic bacilli are a group of bacteria that do not retain the crystal violet dye during the Gram staining procedure. Some examples of gram-negative aerobic bacilli include Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.
A mixed aerobic-anaerobic infection involves both bacteria that require oxygen to grow (aerobic bacteria) and bacteria that do not require oxygen (anaerobic bacteria). These types of infections can occur in various parts of the body, such as the lungs, abdomen, and skin.
