Kytococcus schroeteri: An Emerging Pathogen on the Horizon. Indian Journal of Chest Diseases & Allied Sciences. 2022 Mar; 64(1): 37-400377-9343http://imsear.searo.who.int/handle/123456789/221841Kytococcus has long been considered to be a skin commensal or environmental contaminant. However, it has emerged as an aetiological agent of prosthetic valve infective endocarditis, pneumonia, bacteremia, osteoarticular, and implant/device infections, especially in patients with immunocompromised conditions, such as haematological malignancies, febrile neutropaenia and in patients on immunosuppressant therapy. We report a case of prosthetic valve endocarditis associated with Kytococcus schroeteri in a patient with rheumatic heart disease and mitral valve replacement. Special efforts to reach correct identification have to be made as Kytococcusis, commonly resistant to penicillins and oxacillins; and often needs prolonged treatment with glycopeptides containing combination antimicrobial therapy.Kytococcus schroeteriInfective endocarditisEmerging pathogenJournal ArticleIndiaDepartments of MicrobiologyMedicine, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India
