What type of condition does Cefazolin primarily target?

Cefazolin is a first-generation cephalosporin antibiotic that is primarily effective against bacterial infections. It functions by interfering with the synthesis of bacterial cell walls, ultimately leading to the destruction of the bacteria. This makes it particularly useful in treating a variety of gram-positive bacterial infections, such as those caused by staphylococci and streptococci. Its spectrum of activity covers certain gram-negative bacteria as well, but its main application is in the treatment and prevention of infections caused by susceptible strains of bacteria.

In contrast, cefazolin is not effective against viral infections, as antibiotics do not target viruses. Fungal infections require antifungal medications, and parasitic infections are treated with antiparasitic drugs. Therefore, the role of cefazolin is specifically centered on its antibacterial properties, reinforcing its designation as a treatment for bacterial infections.
