Streptococcus agalactiae, a beta-hemolytic group B streptococcus (GBS) that causes neonatal meningitis and sepsis, is very rarely reported in infective endocarditis (IE). Here, we report a case of late prosthetic aortic valve IE caused by S. agalactiae, which was misidentified as Pediococcus pentosaceus in the VITEK 2 identification system. The identification was confirmed by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) and Sanger's sequencing. The probable cause of the misidentification is discussed. The patient was started on appropriate therapy based on antimicrobial susceptibility testing. At 3 months of follow-up, he was afebrile with normal prosthetic valve function.
