“…T. erinacei is a predominate agent in the cause of zoophilic dermatophytosis (Schauder, 2007), and in many cases treatment using normal therapies is not successful. T. soudanense is a common cause of tinea capitis in parts of Africa and West Asia, and its presence is expanding worldwide (Markey et al, 2003). T. rubrum is a predominate etiologic agent in dermatophytosis, followed by T. mentagrophytes and T. tonsurans (Foster et al, 2004).…”

The antifungal activities of ligustilide and butylidene phthalide, which are major oil components comprising the essential oil of Ligusticum chuanxiong, in combination with antifungal drugs were evaluated. Checkerboard microtiter and microdilution tests were used to measure combined effects against Trichophyton species, T. erinacei, T. mentagrophytes, T. rubrum, T. schoenleinii, T. tonsurans and T. soudanense. Susceptibility of these Trichophyton species to L. chuanxiong essential oil differed distinctly. The fractional inhibitory concentrations (FICIs) against Trichophyton species ranged between 0.27 and 0.56 for ketoconazole combined with ligustilde or butylidene phthalide, indicating synergism or additive effects between the antibiotic and essential oil compounds. Testing by itraconazole instead of ketoconazole, similar combination effects were observed with FICIs from 0.31 to 0.63 against the tested strains of T. mentagrophytes, T. rubrum, T. schoenleinii, and T. soudanense. Thus, data reported here showed that Trichophyton susceptibility to ketoconazole and itraconazole could be notably improved by ligustilde and butylidene phthalide.

“…Previously, a study from 1979 to 1981 of 54 different US locations only identified 14 of 14 696 (0.01%) tinea capitis cases that were caused by T violaceum and T soudanense . Sporadic cases have otherwise been reported intermittently since then . However, more recently, infection by T violaceum and T soudanense has increased in frequency with 25 of 1839 (1.4%) isolates identified in a series out of Baltimore, Maryland from the years 2000 to 2006 .…”

Background/Objective Tinea capitis is a common infection of scalp hair in children. The prevalent etiologic organism has changed significantly over time, which may reflect the complex interaction of environmental factors, genetic predisposition, and movement of populations. We evaluate the prevalence of different infectious organisms causing tinea capitis and describe the clinical characteristics. Methods A retrospective chart review of patients diagnosed with tinea capitis with tissue culture confirmation, who were seen in pediatric dermatology at a tertiary care center from 2010 to 2015. Patient demographics, culture data, and clinical characteristics were evaluated. Inflammatory pattern, characterized by presence of pustules, bogginess, or lymphadenopathy, was noted. Results Forty‐six patients with culture‐positive tinea capitis were identified. In the 18 (42.9%) patients who were infected with either Trichophyton violaceum or Trichophyton soudanenese, all were of African ethnicity. In contrast, Trichophyton tonsurans was identified in a minority of African patients (3.8%), revealing a statistically significant difference between ethnicity and infective species (P‐value < 0.001). T tonsurans was significantly more likely than T violaceum to exhibit an inflammatory pattern (68% vs 22%, P value < 0.027). Conclusions While T tonsurans remained the most common cause of tinea capitis, T violaceum and T soudanense have increased in prevalence. As these latter agents are less inflammatory, clinical diagnosis may be delayed. Studying changes in the infectious cause of tinea capitis can help us create a snapshot to better understand the evolution of our population make‐up, allowing us to provide crucial quality health care to all.

“…Published reports of T. soudanense infections in the United States have been even more infrequent. Although more recent reports describing infections in the United States due to either T. violaceum or T. soudanense are rare, Ohio investigators in 2003 described two sisters adopted from Liberia who had tinea capitis caused by T. soudanense (22).…”

Tinea capitis is of public health importance because of its transmissibility. Trichophyton violaceum and Trichophyton soudanense , which are common causes of tinea capitis in parts of Africa and West Asia, have only rarely been reported to cause dermatophytoses in the United States. We identified 24 patients with 25 positive cultures for T. violaceum or T. soudanense that were processed in a single hospital laboratory in Baltimore, Maryland, between 1 January 2000 and 30 June 2006. Most patients for whom clinical information was available had tinea capitis. There was a marked increase in the isolation of these organisms between the period from 2000 to 2002 and the period from 2003 to 2006, possibly associated with changes in immigration to the Baltimore metropolitan area. The changing epidemiology of this transmissible fungal infection not only is of public health interest as an example of the introduction of a “new” pathogen to an area where it traditionally was not endemic but also is of clinical and microbiological importance given reports suggesting an increasing incidence of tinea capitis in some areas and increasing clinical failure rates of current therapies.
