Diverticulitis?: I'll assume you are asking about the role of antibiotics in diverticulitis. Diverticulosis is the presence of outpouches in the colon wall. It presents with bleeding. Diverticulitis is infection of one of those areas, it will present variably with pain, fever, diarrhea, nausea, inability to defecate, and even sepsis. Diverticulitis is treated with antibiotics, but additional therapy may be needed.

Infection vs. not.: Diverticulitis is an infection of diverticuli treatable with antibiotics. But this treatment does not make the actual diverticuli go away, nor would it prevent you from creating more diverticuli in the future. A high fiber diet with plenty of water will do this.
