ABSTRACT One strain of Trichophyton rubrum CMCC(F)T1i (=CBS 139224) isolated from onychomycosis and one strain of Trichophyton violaceum CMCC(F)T3l (=CBS 141829) isolated from tinea capitis in China were whole-genome sequenced by Illumina/Solexa, while the former was also sequenced by Pacific Biosciences sequencing in parallel.

Background: Trichophyton violaceumis an anthropophilic dermatophyte, endemic in Africa and recently an emerging pathogen in Europe. Objective: To perform a retrospective analysis of dermatophytoses due to T. violaceum between 2007 and 2018, in order to evaluate epidemiological trends in Southern Switzerland (Ticino). Methods: We reviewed all medical records of patients affected by dermatophytosis due to T. violaceum between January 2007 and December 2018 in Bellinzona (Ticino, Switzerland). Results: Dermatophytoses due to T. violaceumwas diagnosed in 44 patients, 33 of which were in the last 4 years. The most affected sex was female (25/44) and the most frequent diagnosis was tinea capitis (30/44). The majority of tinea capitis patients were children younger than 13 years of age (27/30). The main source of contagion were people from endemic areas, especially from Eritrea. Conclusion: In Southern Switzerland T. violaceumhas been rarely diagnosed before 2014. Its increased occurrence seems linked to increased migratory flows from Eritrea. Since it is responsible mainly for tinea capitis, with most of the time no clearly defined alopecia patches, it is important to consider it as a possible diagnosis when facing scalp scaling. Tinea capitis due to T. violaceum is a benign affection, but if left untreated it can spread epidemically, especially among children in schools and kindergartens. Mycological examination is then required, not only for a correct diagnosis and epidemiological data, but also for planning the appropriate treatment.

Abstract A description is provided for Trichophyton violaceum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of man (causing mycoses). Also recorded from buffalo, cat, cattle, dog and mouse (RMVM 6, 3187; 10, 505). The cat, dog, guineapig, monkey and mouse have been infected experimentally. The horse, fowl and pigeon have been implicated as hosts of T. violaceum. DISEASE: Ringworm (dermatophytosis, tinea). The scalp (tinea capitis), beard (tinea barbae), body (tinea corporis) and nails (tinea unguium, onychomycosis) may be infected. Infected hairs show an endothrix type of invasion and do not fluoresce under Wood's light. The hairs may break and curl producing 'black dots' on the scalp (also sometimes produced by other endothrix Trichophyton species). Inflammatory lesions (occasionally with the development of kerion), scarring and alopecia and, occasionally, favus-like lesions may occur. Infections of the subcutaneous tissues, lymph nodes, brain, bones and other internal tissues have been reported (RMVM 3, 1441; 4, 716; 9, 677; 11, 708; 12, 1847; 13, 961, 1572). GEOGRAPHICAL DISTRIBUTION: Worldwide. A dominant cause of scalp ringworm in S. and E. Europe, the Middle East, N. Africa, parts of Central and E. Africa, S. Africa and Asia (RMVM 10, 602; 13, 1558).
