Final answer:
Cephalosporins have different generations of developed agents, ranging from narrow-spectrum to broad-spectrum. Each generation has specific characteristics and is effective against different types of bacteria.
Step-by-step explanation:
Cephalosporins have different generations of developed agents. These generations are classified based on their spectrum of activity, with the first generation having a narrow spectrum and the fourth generation having a broad spectrum. A new fifth-generation cephalosporin has also been developed. Each generation has specific characteristics and is effective against different types of bacteria.
These generations allow healthcare professionals to choose the most suitable cephalosporin based on the specific characteristics of the infection, contributing to more targeted and effective treatment.
