We report here a case in which a strain of Helcococcus kunzii was isolated from a foot abscess, in an immunocompetent patient, after surgery for metatarsal fracture. Correct species identification of the strain was readily obtained on the basis of morphological and biochemical features, together with 16S rRNA analysis. This case demonstrates that this species should be considered a potential pathogen in patients with no underlying disease.

Introduction: Helcococcus kunzii is a commensal bacterium found in the human skin that seldom causes infection. While there is documentation of abscesses; such as foot, breast, and brain abscesses; caused by H. kunzii, there are no reports of its causing umbilical abscesses.

Background: Staphylococcus aureus is the predominant pathogen isolated in diabetic foot infections. Recently, the skin commensal bacterium, Helcococcus kunzii, was found to modulate the virulence of this pathogen in an in vivo model. This study aims to elucidate the molecular mechanisms underlying the interaction between these two bacterial species, using a proteomic approach.

Detection of and / has been made possible by recent advancements in microbiologic diagnostics. We report the first described case of polymicrobial bacteremia secondary to these two unique pathogens, and only the third case of / bacteremia described in the United States. Myiasis has historically been thought of as an infestation.

Purpose: Helcococcus kunzii is a skin commensal, Gram-positive bacterium, mostly isolated from infected chronic wounds. This opportunistic pathogen is usually co-isolated with Staphylococcus aureus. The present dataset explores the production and secretion of H.

Helcococcus kunzii is a commensal Gram-positive bacterial species recovered from the human skin microbiota and considered as an opportunistic pathogen. Although little is known about its clinical significance, its increased abundance has been reported in infected wounds, particularly in foot ulcers in persons with diabetes. This species is usually detected in mixed cultures from human specimens and frequently isolated with Staphylococcus aureus.
