“…21 This also holds true for Candida scrotum infections: a high prevalence of Candida colonisation is known in the preputial space of healthy males. 22 [23][24][25] In conclusion, our study suggests that classical fungal infections of the scrotum have wide range of causative agents, with dermatophytes as prevalent agents. In China, the infection mainly involves young healthy males, and the major causative agent is the geophilic species N. gypsea presenting mild inflammation with thick pseudomembraneous lesions.…”

Summary Background Emergence of highly inflammatory genital dermatophyte infections has been reported from Southeast Asia. In view of this, knowledge of the non‐outbreak fungal flora of the genitals is required as a baseline study. Objectives We present our 12‐year experience in a tertiary clinic with the diagnosis of scrotal fungal infections. Methods A retrospective review was performed of patients with a diagnosis of scrotal fungal infections proven by direct microscopy and culture. Clinical, mycological and treatment data were collected. Results In total, 35 male patients were identified, of which 27 concerned dermatophyte infections and eight were yeasts. Nannizzia gypsea was the most common agent (48.6%), presenting as thick pseudomembraneous lesions limited to the scrotum. Trichophyton rubrum (22.9%) and Epidermophyton floccosum (5.7%) mainly presented erythematous, dry and scaly lesions and involving more sites besides the scrotum. Candida albicans (n = 3), C. glabrata (n = 2), C. guilliermondii (n = 1) and Trichosporon asteroides (n = 1), presented various lesions. Sports, sweating and concurrent tineas are hypothesised as predisposing factors. Conclusions The prevalent causative agent of scrotum infections is N. gypsea, but wide species diversity is observed. All infections show mild skin inflammation. It is suggested that this genital fungal flora represents the current situation prior to clonal dermatophyte outbreaks.

“…It has been well established as an emerging fungus that causes superficial skin lesions and onychomycosis infection, such as dermatophytosis (Arrese, Piérard-Franchimont, & Piérard, 2001;Hay, 2002;Khan, Ahmad, Joseph, & Chandy, 2009;Lacaz et al, 1999). The pathogen can also cause deeper infections, such as subcutaneous abscesses (Rockett, Gentile, Zygmunt, & Gudas, 1996), sinusitis (Dunn et al, 2003) and even fungemia and disseminated infections in immunocompromised patients (Marriott et al, 1997;Sigler et al, 1997;Tan, Sigler, Gibas, & Fong, 2008).…”

First detection of Neoscytalidium dimidiatum associated with canker disease in Egyptian Ficus trees

2018

In September 2013, a canker disease of Ficus nitida and F. benjamina was reported for the first time in Assiut governorate, Egypt. Infected samples were collected from various locations. Pure cultures of a fungus were isolated on potato dextrose agar at 25°C from diseased plants. Morphological investigation and DNA sequencing showed that the causal agent was Neoscytalidium dimidiatum. A pathogenicity test conducted using 2-year-old plants of each host gave 70%-80% infection, and the pathogen was reisolated from the inoculated plants. A pure culture of N. dimidiatum was deposited in the culture collection of the Assiut University Mycological Centre (AUMC) under the code AUMC 9293 and the ITS sequence was placed in NCBI under accession number KX985929.

Novel Use of a Swimming Pool Biocide in the Treatment of a Rare Fungal Mastoiditis

Successful treatment of a chronic Lecythophora hoffmannii fungal mastoiditis involved a combination of radical surgical removal of all apparent infected tissue along with local treatments with polyhexamethylene biguanide, a common swimming pool biocide agent under the brand name Baquacil (Avecia, Manchester, United Kingdom). Given the prolonged course of treatment, this report particularly stresses the importance of concurrent surgery combined with creative local antimicrobial therapy to eliminate an unusual fungal infection in an immunocompetent host.
