seraticin seraticin seraticin is an antibiotic discovered by scientists at swansea university able to inhibit 12 different strains of methicillin-resistant staphylococcus aureus (mrsa), as well as e. coli and c. difficile. the research was funded by the charity action medical research, with support from the rosetrees trust. seraticin was isolated as a compound of less than 500 da molecular weight from the maggot secretions of the common green bottle fly (lucilia sericata). it was patented in 2010 and has the empirical formula c10h16n6o9, but its chemical identity is unknown. seraticin identifiers cas number 1039756-04-1 properties chemical formula c10h16n6o9 molar mass 364.271 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references
