A rare case of human mycosis by Rhizoctonia solani

Abstract

Rhizoctonia solani is a most widely recognized strong saprophyte with a great diversity of host plants. It is a first ever case of extensive human mycosis caused by Rhizoctonia solani in a 65-year-old diabetic and hypertensive farmer, with a history of head injury caused by fall of mud wall. Necrotic material collected revealed septate fungal hyphae with bacterial co-infection. Fungal culture on SDA at 25°C showed cotton wooly growth progressing to greyish-white to shiny metallic black colonies and identified on basis of septate mycelial growth without conidia, right angle branching, presence of compact hyphal forms and anastomosis between branching hyphae on LPCB mount.

Analysis on Synthesis of Silica Nanoparticles and its Effect on Growth of T. Harzianum & Rhizoctonia Species

“…It is a first ever case of extensive human mycosis caused by Rhizoctonia solani in a 65-year-old diabetic and hypertensive farmer, with a history of head injury caused by fall of mud wall. Necrotic material collected revealed septate fungal hyphae with bacterial co-infection and after mycological study & diagnosis it was confirmed the presence of rhizoctonia solani [16]. So, in this paper we tested anti-fungal effect of silica nanoparticles against these two fungi i.e.…”

Hexosomal Dispersion: A Nano-Based Approach to Boost the Antifungal Potential of Citrus Essential Oils against Plant Fungal Pathogens

“…Herein, the fungicidal activity of the essential oil obtained from the peels of Citrus lemon , Citrus aurantifolia , Citrus maxima , and Citrus sinensis were assessed against seven pathogenic fungi that have been reported as pathogenic to humans too [ 16 , 17 , 18 , 19 ], namely Rhizoctonia solani , Sclerotium rolfsii , Fusarium solani , Fusarium oxysporum , Fusarium semtectium , Botrytis cinerea , and Alternaria alternata . In the presented study, a nano-based valorization approach is reported to establish a novel hexosomal system containing the most active essential oil, allowing for an enhancement of the efficiency of natural fungicides, reducing costs and increasing competitiveness.…”
