Antibiotic synergy with enterococcal endocarditis experienced a high relapse rate when penicillin G alone was used for treatment and a demonstrably lower relapse rate when streptomycin was combined with penicillin G to combat the infection. Since that time the research community has conducted numerous studies regarding the effects and possibilities of antibiotic combinations. Today, combination therapy is recognized as providing a broad spectrum of antibiotic coverage, effectively fighting polymicrobial infections, minimizing selection for antibiotic resistant strains, lowering dose toxicity where applicable, and in some cases providing synergistic activity. Antibiotic synergy is desirable in a clinic sense for several reasons. At the patient
Antibiotic-associated diarrhea an infection caused by the probiotic supplements. "Clostridium difficile", also known more commonly as "C. diff", is known to account for 10 to 20 percent of antibiotic-associated diarrhea cases. The reasoning for this, is that the antibiotics administered for the treatment of certain diseases processes such as inflammatory colitis also inadvertently kills a large portion of the gut flora, the normal flora that is usually present within the bowel. With this lower amount of "healthy" bacteria present, the overgrowth of "C. diff" is then responsible "for elaborating the enterotoxin". Antibiotic-associated diarrhea Antibiotic-associated diarrhea (AAD) results from an imbalance in the
