A series of 13 salicylamide derivatives was assessed for antibacterial activity against three isolates of vancomycin-resistant Enterococcus faecalis (VRE) and Enterococcus faecalis ATCC 29212 as a quality standard. The minimum inhibitory concentration was determined by the broth microdilution method with subsequent subcultivation of aliquots to assess minimum bactericidal concentration. The growth

The present invention relates to halogenated salicylanilides, or pharmaceutically acceptable salts or esters thereof, for use in the treatment of an infection in a subject caused by Clostridium bacteria, particularly a C. difficile infection. The halogenated salicylanilides are expected to be useful in the treatment of C. difficile associated diseases including C. difficile associated diarrhea and C. difficile associated colitis.
The invention relates to a halogenated salicylanilide selected from closantel, rafoxanide, oxyclozanide and niclosamide and derivatives thereof including salts, hydrates, esters and the like for use in the topical treatment or prevention of infections caused by Gram-positive bacteria such as Staphylococcus, in particular Staphylococcus aureus, and Streptococcus, in particular Streptococcus pyogenes. Grain positive bacteria treated with the halogenated salicylanilides exhibit a very low frequency of appearance of resistant mutants compared to commonly used topical antibiotics.

A method of protecting a host from an enteric toxigenic pathogen comprises administering a salicylanilide to the host. A method of reducing virulence of an enteric toxigenic pathogen comprises administering a salicylanilide to a host infected with or at risk of infection with pathogen. A method of reducing recurrence of an infection caused by an enteric toxigenic pathogen, comprises administering a salicylanilide to a host previously infected with the pathogen.
