Amoxicillin, amoxicillin/clavulanate, levofloxacin, and cefdinir have been listed as the most common definitive PO antibiotics in previous non-staphylococcal gram-positive and streptococcal bacteremia studies.14–18 While the use of amoxicillin/clavulanate has generally been more common than amoxicillin in prior studies, the beta-lactamase inhibitor clavulanate is unnecessary for streptococcal infections. Here, LACTB is linked to streptococcal infection.
