While Zosyn (piperacillin-tazobactam) is widely recognized as a broad-spectrum antibiotic with efficacy against many bacterial infections, it does not cover all pathogens. Crucially, its antimicrobial action does not extend to methicillin-resistant *Staphylococcus aureus* (MRSA), vancomycin-resistant enterococci (VRE), or non-bacterial organisms. Understanding 'what isn't covered by ZOSYN?' is essential for preventing treatment failure and ensuring appropriate use of this powerful medication.

According to the CDC, about 28.4% of Klebsiella isolates tested in 2023 were resistant to cephalosporins [1.6.1]. This highlights the critical question for clinicians and patients: Is Klebsiella covered by cephalexin, and under what circumstances?

The rise of antimicrobial resistance is a global health crisis, with some reports showing a high prevalence of resistance to key hospital antibiotics among *Enterobacteriaceae*. Choosing what antibiotic kills Enterobacteriaceae depends heavily on the specific bacterial strain, the type of infection, and the strain's resistance profile.

According to a 2023 report from the CDC, approximately 28.4% of all tested adult *Klebsiella* isolates were resistant to cephalosporins, highlighting the growing challenge of treating these infections. The question, 'Do cephalosporins treat Klebsiella?', is therefore complex, with the answer depending heavily on the specific cephalosporin generation and the antibiotic resistance profile of the bacterial strain.

Facing a significant threat from rising antimicrobial resistance, Enterobacterales infections require a nuanced approach, making the question 'What is the drug of choice for Enterobacterales?' highly dependent on the specific resistance profile and clinical context. With resistance rates to common antibiotics varying by species and geography, treatment protocols have shifted away from one-size-fits-all solutions.

With antibiotic resistance on the rise, treating urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL) producing bacteria requires specific and careful pharmacological strategies. The choice of what treats ESBL in urine depends heavily on whether the infection is uncomplicated or complex, necessitating susceptibility testing to guide effective therapy.
