Talaromyces indigoticus Takada & Udagawa, the First Record for Panama and the American Continent

Abstract

In a survey of mycotic human skin and nail lesions in Chiriquí, Western Panama, Talaromyces indigoticus was isolated in one case. This ascomycete is characterised by formation of gymnothecia containing oval, spinose and yellow ascospores, which become blue in mounting fluids, and by short monoverticillate or biverticillate penicilli. It is here reported the first time for Panama and the American continent. Because the strain was isolated from an onychomycosis together with a dermatophyte and other fungal strains, the pathological impact of Talaromyces indigoticus is not evident.

New Talaromyces species from indoor environments in China

“…Other medically important Talaromyces species including T. indigoticus , T. piceus , T. indigoticus , T. helicus , T. rugulosus , T. purpurogenus , T. radicus and T. verruculosus have been reported in superficial or disseminated, fatal infections (Neuhann, 1976, Swietliczkowa et al., 1984, de Hoog et al., 2000, Horré et al., 2001, Santos et al., 2006, de Vos et al., 2009, Weisenborn et al., 2010, Tomlinson et al., 2011). Among the nine new species described here, T. adpressus , T. beijingensis , T. diversiformis , T. fusiformis and T. reverso-olivaceus grow well at 37 °C, thus are more risky for human health.…”

Overview of fungal isolates on heritage collections of photographic materials and their biological potency

“…indigoticus) [139,140]. Fusarium spp., also common in photographic library air [20], are reported to be involved in infections, especially superficial (keratitis and onychomycosis), locally invasive or disseminated infections [141].…”

Polyphasic taxonomy of the genus Talaromyces

“…Other Talaromyces species have also been reported to be medically important. For example, T. indigoticus was isolated from skin and nail lesions from a male who was affected by onychomycosis in Western Panama ( Weisenborn et al 2010 ), T. piceus caused both fungaemia ( Horré et al 2001 ) and rib osteomyelitis in an X-linked chronic granulomatous disease (X-CGD) patient ( Santos et al 2006 ), T. radicus caused a fatal infection in a German shepherd dog ( de Vos et al 2009 ), T. helicus caused granulomatous lymphadenitis in a labrador retriever ( Tomlinson et al 2011 ), and T. amestolkiae and T. stollii were isolated from the lungs and sputum of immunocompromised patients ( Yilmaz et al 2012 ).…”
