The combination of a first species which is a polyanionic compound and a second species which is an antimicrobial agent is used for the treatment of microbial biofilms and for the topical treatment of wounds. The combination may be incorporated in a wound dressing. The polyanionic compound may be a polyphosphate, such as an alkali metal polyphosphate, e.g. sodium hexametaphosphate. Examples of antimicrobial agents include metallic silver, silver compounds, iodine, PHMB (polyhexamethylene biguanide), acetic acid, chlorhexidine, aminoglycosides (e.g. amikacin, gentamicin, streptomycin and tobramycin), ansamycins, carbacephem, cephalosporins, glycopeptides (e.g. vancomycin), macrolides (eg clarithromycin), monobactams and sulfonamides). |
