Nail infection caused byOnychocola canadensis: report of the first four British cases

Onychomycosis caused by Onychocola canadensis: the first report in Estonia and lessons to learn

“…In 1990 Sigler and Congly reported O. canadensis as a new agent of onychomycosis. A review of literature up to March 2013 gave 51 reported cases . In 2002, Gibas et al .…”

Onychomycosis due to Onychocola canadensis

“…O. canadensis is an uncommon slow‐growing nondermatophyte mould . O. canadensis ‐induced onychomycosis was first described in Canada in 1990, 1 and has since been reported in New Zealand 2 France 3,4 and England 5 . O. canadensis can occasionally cause onychomycosis, and less commonly tinea manuum 2 .…”

“…O. canadensis-induced onychomycosis was first described in Canada in 1990, 1 and has since been reported in New Zealand 2 France 3,4 and England. 5 O. canadensis can occasionally cause onychomycosis, and less commonly tinea manuum. 2 The mycological diagnosis is based on the microscopic findings, and consistent culture of the mould from multiple serial specimens.…”

A revision of malbranchea-like fungi from clinical specimens in the United States of America reveals unexpected novelty

“…The genus Arachnomyces (family Arachnomycetaceae , order Arachnomycetales; Malloch and Cain 1970 , Guarro et al 1993 ), characterized by the production of brightly coloured cleistothecial ascomata bearing setae, and by the production of an onychocola-like (Sigler et al 1994 ) or a malbranchea-like (Udagawa and Uchiyama 1999 ) asexual morph, have been also implicated in animal and human infections. Specifically, Arachnomyces nodosetosus and Arachnomyces kanei have been reported as causing nail and skin infections in humans (Sigler and Congly 1990 ; Sigler et al 1994 ; Campbell et al 1997 ; Contet-Audonneau et al 1997 ; Kane et al 1997 ; Koenig et al 1997 ; Gupta et al 1998 ; Erbagci et al 2002 ; Gibas et al 2002 ; Llovo et al 2002 ; O’Donoghue et al 2003 ; Gibas et al 2004 ; Stuchlík et al 2011 ; Järv 2015 ; Gupta et al 2016 ). More recently, Arachnomyces peruvianus has been reported to cause cutaneous infection (Brasch et al 2017 ) and A. glareosus was isolated from nail and skin samples (Gibas et al 2004 ; Sun et al 2019 ).…”
