In vivo comparison of two silver sulfadiazine antimicrobial agents on burn wound infection.
A controversy exists with regard to the relative efficacy of two preparations of silver sulfadiazine (AgSD), Silvadene and Flint's Silver Sulfadiazine Cream. We compared the susceptibility of Staphylococcus aureus and clinical Gram-positive cocci, Gram-negative rods, and mixed floral isolates by the Nathan's agar well diffusion method and found no differences. However, when S aureus-infected rat burn wounds were treated with these antimicrobial creams over a period of ten days, Silvadene significantly lowered bacterial counts, whereas results after treatment with Flint's Silver Sulfadiazine Cream were no different from those of the control group, which received no treatment. These data imply that Silvadene controls S aureus-generated burn wound infections better than the Flint product.
