Lysinebacillum Bacteriemia in an Adult Cancer patient

Abstract

Lysinibacillus is a genus of rod-shaped gram-positive bacteria most often found in soil and plantlife, however, it has been isolated from air and from the human intestinal microbiome as well. The genus Lysinibacillus is most often disregarded when isolated in the laboratory; nevertheless, it usually acts as an opportunist in immunocompromise hosts with various mortality rates. Here we present a case of bacteriemia due to Lysinibacillus in a patient whose clinical history and risk factors suggested otherwise. It is crucial to pay attention to the identification of this types of organisms, particularly, when they come from techniques such as spectroscopy. This in order to have a broader picture when addressing this type of patients.

Peritoneal Dialysis-Related Peritonitis Caused by Lysinibacillus sphaericus

“…To the best of our knowledge, this case is the second case report of PD-related peritonitis (PDRP) and the third case report of infection in end-stage kidney disease (ESKD) patients. L. sphaericus is reported to cause infection in immunocompromised hosts such as postsplenectomy, malignancy, or receiving bone marrow transplant patients [9][10][11]. L. sphaericus is an uncommon organism causing peritonitis in PD patients.…”
