<unk> s are used in<unk>  for a number of reasons: * to treat multiresistant organisms, such as carbapenem-resistant Enterobacteriaceae. * Amoxicillin/clavulanic acid, which includes the beta lactam amoxicillin with the suicide inhibitor clauvanic acid, which helps the amoxicillin overcome the action of beta lactamase * because a person may be infected with more than one microbe simultaneously, for example infections of the abdominal cavity after bowel perforation. * because<unk> s used together may act synergisticly to increase the efficacy of both, * because<unk> s used together may have a broader spectrum than each<unk>  used individually.
