Rare Bacteria Infecting the Heart and Affecting the Kidney of a Young Child

Rare bacteria can lead to infective endocarditis, which may lead to renal involvement as severe glomerulonephritis. We report our experience of a 12-year-old child who presented with infective endocarditis and blood culture-grown Gemella morbillorum - a rarely reported bacteria. The clinical picture was further complicated with severe glomerulonephritis. Renal biopsy was suggestive of crescentic glomerulonephritis. The child was managed with antibiotics, steroids, and plasmapheresis and responded well to the treatment. To our knowledge, this is the first report of G. morbillorum endocarditis with immune complex deposition and necrotizing glomerulonephritis in a child.
