Cefsulodin is a third-generation cephalosporin antibiotic that is active against Pseudomonas aeruginosa and was discovered by Takeda Pharmaceutical Company in 1977.[1][2][3][4]

TAP Pharmaceuticals had a new drug application on file with FDA for cefsulodin under the brand name Cefonomil as of 1985.[5]

Cefsulodin is most commonly used in cefsulodin-irgasan-novobiocin agar to select for Yersinia microorganisms.[6] This agar is most often used in water and beverage testing.
