Native aortic valve infective endocarditis caused by Streptococcus agalactiae in a renal transplant recipient.

Infections with Streptococcus agalactiae or group B Streptococcus (GBS) are usually seen during pregnancy or in the neonatal period. The authors report a case of GBS aortic valve endocarditis in a renal transplant patient. GBS endocarditis is often aggressive despite appropriate therapy. The reported patient required prolonged antibiotics and valve replacement. To the authors' knowledge, this is the only reported case of GBS endocarditis in a renal transplant patient.
