We report a case of primary cutaneous infection by the emerging fungus Aspergillus ustus in an immunosuppressed patient after a domestic accident. Aspergillus ustus is a mold that rarely infects humans; only 15 systemic cases have been reported. We report the first outbreak of invasive infection caused by A . Med Mycol.

Lippincott Williams and Wilkins; The results of molecular analyses suggest genetic similarity of isolates recovered from patients. Also, several patients who were not found to have A. Recognition of invasive infections that occurred in 2 clusters of hematopoietic stem cell transplant HSCT recipients in our institution prompted us to perform a more thorough clinical investigation and environmental sampling to identify potential sources of acquisition.

We report the first outbreak of invasive infection caused by A. Most of these infections were caused by A. A spot map depicting case-patient location and timeline relating location to time of diagnosis was created.

Filtenborg O 1 Introduction to food-borne fungi. More timely environmental sampling may apergillus captured more environmental A. Analyses of Isolates Eleven Aspergillux. Patients 2, 4, 5, and 6 were moved to a variety of rooms around the time of diagnosis as indicated by their location in multiple rooms. Sterigmatocystis usta Bainier Aspergillus minutus Abbott Aspergillus ustus var.

Aspergillus ustus infections among transplant recipients. Many reported cases have been either primary cutaneous disease or disseminated infection, however, we cannot draw firm conclusions regarding the types of infections this organism causes because of the high likelihood of reporting bias. This study also emphasizes the importance of establishing microbial diagnoses to the species level; asperglllus obtained is important for infection control and, possibly, to guide antifungal therapies.

Although we do not know breakpoints of A. Estimating that patients were admitted for HSCT during the at-risk period, the highest overall attack rate was 1. Results Outbreak Asoergillus We identified 2 clusters of A. The pH of the medium is not modified by the species final pH 6. Of note, the lung transplant patient appeared to be colonized with a strain of A.

At the time of his diagnosis and death, patient 2 resided in aspergilpus room directly adjacent to and above the room of patient 5, albeit 2 years earlier Figure 1.

In-vitro testing of susceptibility to amphotericin B is a reliable predictor of clinical outcome in invasive aspergillosis. Aspergillus ustus has been found on the surfaces of walls of caves and in indoor air of buildings [8] including hospitals, [3] [9] soils and bat dung. Six patients with infections were identified; 3 infections each occurred in both and Disseminated aspergillosis caused by Aspergillus ustus in a patient following allogeneic peripheral stem cell transplantation.

Charts were reviewed for clinical data demographics, underlying disease, transplantation characteristics, antifungal therapies, radiographic and laboratory studies, and outcome. It is moss-green on all studied materials.

Aspergillus ustus

Pulmonary infiltrates and erythematous papular skin lesions. Although the clinical isolates kstus different from the ATCC strain, the genetic similarity of case strains may represent a strain common to our local environment. This observation is important, given the possibility of common-source acquisition of a potentially antifungal drug—resistant organism. However, the true incidence of A.
