What kind of action do second generation cephalosporins generally exhibit?

• A. Primarily effective against gram-positive bacteria
• B. Effective against both gram-positive and gram-negative bacteria
• C. Definitively ineffective against anaerobes
• D. Only effective in urinary tract infections

Answer: (B)

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.
