Additionally, clinicians can use them for bone, respiratory tract, genitourinary tract, biliary tract, bloodstream infection, otitis media, and surgical prophylaxis.
#PENICILLIN CEPHALOSPORIN CROSS REACTIVITY SKIN#
Oral first-generation cephalosporins are commonly prescribed to use against uncomplicated skin and soft tissue infections such as cellulitis and abscesses commonly due to a staphylococci spp. Gram-negative bacteria that are more susceptible to first-generation cephalosporins are Proteus mirabilis, E. First-generation cephalosporins have active coverage against most gram-positive cocci such as staphylococci spp. and streptococci spp. while having minimal coverage against gram-negative bacteria. Fifth-generation cephalosporins have coverage against methicillin-resistant staphylococci and penicillin-resistant pneumococci.įirst-generation cephalosporins include cefazolin, cephalothin, cephapirin, cephradine, cefadroxil, and cephalexin. Fourth-generation cephalosporins have similar coverage as third-generation cephalosporins but with additional coverage against gram-negative bacteria with antimicrobial resistance, e.g., beta-lactamase. Third-generation cephalosporins have less coverage against most gram-positive organisms but have increase coverage against Enterobacteriaceae, Neisseria spp., and H. influenza), Moraxella catarrhalis, and Bacteroides spp. Second-generation cephalosporins have coverage against Haemophilus influenza (H. coli), Proteus mirabilis, and Klebsiella pneumoniae. First-generation cephalosporins have coverage against most gram-positive cocci as well as some gram-negative bacteria, e.g., Escherichia coli (E. Cephalosporins are antimicrobials grouped into five generations based on their spectrum of coverage against gram-positive and gram-negative bacteria and their temporal discovery.
