“…Our literature review also identified 6 reported cases of Kytococcus pneumonia. Five of these were in conjunction with hematological malignancy (4 AML and 1 hairy cell leukemia) [11–13, 17]. The sixth patient had no hematologic condition but was moderately immunocompromised by taking prednisone 20 mg daily for 2 years for management of refractory asthma [3].…”

Introduction. Kytococcus schroeteri is an infrequently isolated Gram-positive coccus often encountered as a commensal bacterium. Only eighteen cases of human infection associated with this organism have been previously reported. Most of these cases involved patients with implanted prosthetic materials or patients with immunosuppressive conditions. It has been described in prosthetic valve endocarditis and in select patients with hematologic diseases but only one prior report as being involved in osteoarticular infections. Case Presentation. We describe a case of postsurgical osteoarticular hardware-related infection by K. schroeteri and discuss a possible association with implanted prosthetic material. Conclusion. Other clinical presentations of K. schroeteri, including reported infection syndromes, antimicrobial susceptibility profiles, and treatment outcomes, are also reviewed.

“…K. schroeteri is an underrecognized and underreported organism. Hodiamont et al reported on two cases of pneumonia and bacteremia caused by K. schroeteri [ 4 ]. In their research they came across six cases of pneumonia and bacteremia that were previously identified as Micrococcus sp.…”

The Kytococcus genus formerly belonged to Micrococcus. The first report of a Kytococcus schroeteri infection was in 2002 in a patient diagnosed with endocarditis. We report a case of central line associated Kytococcus schroeteri bacteremia in a patient with underlying Hairy Cell Leukemia. Kytococcus schroeteri is an emerging infection in the neutropenic population and in patients with implanted artificial tissue. It is thought to be a commensal bacterium of the skin; however, attempts to culture the bacteria remain unsuccessful. There have been a total of 5 cases (including ours) of K. schroeteri bacteremia in patients with hematologic malignancies and neutropenia and only 18 documented cases in any population. Four of the cases of bacteria in neutropenic patients have been fatal, but early detection and treatment could make a difference in clinical outcomes.

“…However, K. schroeteri can also cause severe to fatal infections. So far, K. schroeteri has been identified as the causative agent in cases of prosthetic valve endocarditis (n55) (Aepinus et al, 2008;Becker et al, 2003;Mnif et al, 2006;Poyet et al, 2010;Renvoise et al, 2008), pneumonia (n53) (Hodiamont et al, 2010;Mohammedi et al, 2005), spondylodiscitis (n51) (Jacquier et al, 2010) and VPS infection (n51) (Jourdain et al, 2009).…”

“…Kytococci seem to be intrinsically resistant to penicillin and oxacillin (Becker et al, 2002). Therefore, the antimicrobial therapy reported in other case studies included vancomycin and gentamicin (Hodiamont et al, 2010) plus rifampicin (Becker et al, 2003;Aepinus et al, 2008;Mnif et al, 2006), or vancomycin plus gentamicin (Jourdain et al, …”
