Cutaneous chromomycosis caused by Arthrinium arundinis

et al. 2022

An 85-year-old man, a wood processing worker native to and resident in Shandong, China, attended our dermatology clinic for a 10-year history of the verrucous plaque on the back of his right hand. This lesion began as a red papule after trauma. With time, it gradually increased and formed a warty plaque with crust on the surface, accompanied by mild pruritus and pain. A variety of drugs had been applied to treat the lesion (details are unknown), but there was no significant improvement. The patient was otherwise in good health. Physical examination revealed an irregular, well-demarcated, verrucous plaque on the patient's right hand, covered with yellow thick crusts, without pus and exudate (Figure 1).

“…CH1307 of this fungal species produced homoharringtonine, which is an effective treatment for leukaemia [80]. Arthrinium arundinis is described as an endophyte and plant and mammal pathogen, and it is a commonly occurring, widely distributed species [40,81]. On the other hand, secondary metabolites (prenylated diphenyl ethers) secreted by this species show a selective antifungal activity against Mucor hiemalis, and exhibit an inhibitory activity against A. alternata.…”

Species Diversity of Micromycetes Associated with Epipactis helleborine and Epipactis purpurata (Orchidaceae, Neottieae) in Southwestern Poland

et al. 2020

The Orchidaceae family is a diverse family of flowering plants that occur naturally in most parts of the world. However, fungal communities inhabiting different parts of orchids are not sufficiently described. The aim of the study was to conduct a mycological evaluation of Epipactis helleborine and E. purpurata (Orchidaceae), which grow naturally in Lower Silesia (SW Poland), by identifying the species composition of the culturable micromycetes fungi on the surfaces of the plants and from the inner layers of the tissues. Fungi were identified based on a phenotypic and genotypic analysis. To our knowledge, this is the first such analysis. This study showed that more species of micromycetes were cultured from E. helleborine compared with E. purpurata. The flowering plants of E. helleborine were inhabited by the largest number of culturable fungal species (13 species), and the fewest species were isolated from the flowering plants of E. purpurata (eight species). Some of these fungal species may be pathogens of the plants. The surface tissues of the orchids were mainly inhabited by Mucor moelleri and/or Penicillium biourgeianum. The inner layers of these plants were the most colonized by Alternaria tenuissima and/or Arthrinium arundinis and/or Fusarium sporotrichioides. The relative dominance of these fungal species depended mainly on the development phase of the plants.

Medical Mycology Case Reports

“…In the present case, to reduce the chances of NDFF being a contaminant, the following criteria were used: the identification of irregular hyphae in the direct mycological examination of the nail scraping of three consecutive collections with intervals of one month between each one; obtaining three positive cultures on Sabouraud dextrose agar in the three different collections; and the failure to obtain dermatophyte fungi isolation in cultures of the same nail material on Mycosel® agar [ 2 , 4 ]. For species identification, it was performed the sequencing of ITS and TEF1-α fungus genes [ 7 , 16 ].…”

Onychomycosis caused by Arthrinium arundinis in leprosy patient: Case report

et al. 2020

We report a case of a 56-year-old Brazilian woman, with relapsing lepromatous leprosy, and onychomycosis caused by a non-dermatophyte filamentous fungi. The pathogenic fungi was identified as Arthrinium arundinis and treated with chemical abrasion of the nail with 40% urea and application of terbinafine cream. Onychomycosis caused by Arthrinium species is rare, and this is the second reported case.
