What kind of action do second generation cephalosporins generally exhibit?

Second generation cephalosporins are known for their broader spectrum of activity compared to first generation cephalosporins. They are effective against both gram-positive and gram-negative bacteria. This includes enhanced activity against various gram-negative organisms such as Haemophilus influenzae, Enterobacter species, and Neisseria species, while still retaining some effectiveness against gram-positive bacteria like Streptococcus and Staphylococcus.

This dual efficacy is a key characteristic of second generation cephalosporins, making them suitable for treating a wide range of infections, such as respiratory tract infections and certain types of skin and soft tissue infections. In contrast, first generation cephalosporins tend to be more focused on gram-positive organisms, and other options do not accurately reflect the overall activity of second generation cephalosporins or their potential uses in clinical practice.
