A fatal case of pneumonia caused by Thermothelomycesthermophila. J Infect Chemother 2022; 29:87-89.

Abstract
Thermothelomyces thermophila (formerly Myceliophthora thermophila) is usually found in soil and specifically compost as an environmental dematiaceous fungus. Here, we report the first case of invasive pulmonary infection caused by T. thermophila in a pediatric patient with acute lymphoblastic leukemia. T. thermophila was serially cultured from bronchoalveolar lavage (BAL) fluid and sputum samples obtained from this patient with respiratory symptoms. The patient received antifungal treatment with liposomal amphotericin B (160 mg daily) and itraconazole (200 mg daily) combination therapy, but she died. By the antifungal susceptibility testing, low minimum inhibitory concentrations (MIC) were observed for itraconazole (MIC 0.06 μg/mL), voriconazole (MIC 0.12 μg/mL), and posaconazole (MIC 0.03 μg/mL) but high MIC was observed with amphotericin B (MIC 4.0 μg/mL). Since T. thermophila is usually found in the environment, it can be considered as a contaminant and may cause difficulties in diagnosis. Therefore, it is necessary to confirm the potential of pathogen through repeated culture and to conduct an antifungal susceptibility testing to find a suitable antifungal agent.

An invasive infection caused by the thermophilic mold Talaromyces thermophilus. Infection 2021; 49:1347-1353. [PMID: 34195950 PMCID: PMC8613165 DOI: 10.1007/s15010-021-01648-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Accepted: 06/22/2021] [Indexed: 11/06/2022]
Abstract
Background Increasing incidence of invasive infections caused by rare fungi was observed over the recent years. Case Here, we describe the first reported case of an infection caused by the thermophilic mold Talaromyces thermophilus. Cultivation and, hence, identification of this fastidious organism is challenging since standard incubation conditions are not sufficient. Retrospective analysis of patient samples and in vitro experiments demonstrated that testing for fungal antigens, i.e., the cell wall components galactomannan and β-1,3-d-glucan, is a promising tool.

Cross-reactivity of Fusarium spp. in the Aspergillus Galactomannan enzyme-linked immunosorbent assay. J Clin Microbiol 2012; 50:1051-3. [PMID: 22205818 DOI: 10.1128/jcm.05946-11] [Citation(s) in RCA: 125] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/22/2022] Open
Abstract
Nine of 11 hematological patients with disseminated/deep-seated Fusarium infection tested at least twice for Aspergillus galactomannan (GM) had repeated positive results in the absence of Aspergillus isolation in culture. The centrifuged supernatants of 12 Fusarium isolates were tested by a GM enzyme-linked immunosorbent assay (EIA). All the isolates produced positive reactions when tested undiluted. These results show cross-reactivity of Fusarium spp. with Aspergillus GM that may constitute a drawback with respect to the specificity of the Platelia EIA.

Abstract
Graphium basitruncatum is genetically and morphologically distinct from other Graphium and Scedosporium species, and has been reported only once previously as a cause of human disease. We report a case of Graphium basitruncatum fungemia in a two year old child with dyskeratosis congenita who underwent stem cell transplantation two months prior to infection.
