Cefazolin Antimicrobial Susceptibility disks
Cefazolin , also known as cefazoline or cephazolin is a first-generation cephalosporin antibiotic. Cephalosporins fall into the category of β-Lactam (beta-lactam) antibiotics. Cefazolin is a broad spectrum antibiotic that is often used to treat different types of infections including urinary tract, skin, and bone infections.
Cefazolin has been shown to be effective in treating methicillin-susceptible Staphylococcus aureus (MSSA) but does not work in cases of methicillin-resistant Staphylococcus aureus (MRSA). In many instances of staphylococcal infections, such as bacteremia, it is an alternative to penicillin in patients who are allergic to penicillin. However, there is still potential for a reaction to occur with Cefazolin and other cephalosporins in patients allergic to penicillin. Resistance to Cefazolin is seen in several species of bacteria, such as Mycoplasma and Chlamydia, in which case different generations of cephalosporins may be more effective. In addition, it does not fight against Enterococcus, anaerobic bacteria or atypical bacteria among others.
As a first-generation cephalosporin antibiotic, Cefazolin and other first-generation antibiotics are very active against gram-positive bacteria and some gram-negative bacteria. Their broad spectrum of activity can be attributed to their improved stability to many bacterial beta-lactamases compared to penicillins.
