What type of bacteria does Cefdinir target?

Cefdinir is a third-generation cephalosporin antibiotic that is effective against a broad spectrum of bacteria. It targets both gram-positive and gram-negative bacteria, which allows it to treat a variety of infections. The mechanism of action of Cefdinir involves interfering with bacterial cell wall synthesis, ultimately leading to cell lysis and death.

Specifically, Cefdinir has activity against common gram-positive organisms such as Streptococcus pneumoniae, while also being effective against several gram-negative pathogens like Haemophilus influenzae and Moraxella catarrhalis. This dual activity makes it a versatile choice for treating infections such as pneumonia, skin infections, and sinusitis.

In contrast, focusing only on gram-positive or gram-negative bacteria would limit the effectiveness of the antibiotic, and targeting viral pathogens is outside the scope of Cefdinir's action, as antibiotics do not work against viruses. Therefore, the answer indicating a range of gram-positive and gram-negative bacteria precisely captures the effectiveness of Cefdinir.
