text: Since aztreonam has a poor affinity for PBPs 1a and 1b of susceptible Gram-negative bacteria, it is not as rapidly bactericidal as some other β-lactam antibiotics (e.g. imipenem, cefotaxime, cefoxitin, ceftriaxone) against these organisms.
text: Aztreonam also has poor affinity for the PBPs of anaerobic bacteria.
