P. Domenico et al., BISMUTH MODULATION OF ANTIBIOTIC-ACTIVITY AGAINST GASTROINTESTINAL BACTERIAL PATHOGENS, Medical microbiology letters, 3(3), 1994, pp. 114-119
Bismuth subsalicylate (BSS) antimicrobial activity was tested in combi
nation with several antibiotics against enteric pathogens. BSS promote
d rifampicin or gentamicin activity, yet markedly inhibited the activi
ty of imipenem. Other antibiotics were not affected by BSS against ent
eric pathogens. In conclusion, BSS can exhibit synergy or antagonism w
ith antibiotics in vitro, which should be considered when devising com
bined therapy for gastrointestinal disorders.
