“…The type strain of this taxon is in clade E. T. erinacei is the oldest name in this group. Synonymy with T. erinacei was supposed earlier by Rippon [81] but contested by Pereiro [82]. CBS 108.91 does not correspond with the original description and is probably a misidentification.…”

Most members of the anamorph genus Trichophyton are anthropophilic and have evolved with the human host. Classical parameters for the identification of dermatophytes include clinical features, cultural characteristics, conidial morphology and physiological test results. Phenotypic variability and pleomorphism due to culturing on artifical media is common among this group of organisms and has led to the description of numerous species. The validity of taxa around T. mentagrophytes and T. tonsurans was verified. Morphological and physiological features were compared to results of three different molecular techniques (sequencing of the internal transcribed spacer (ITS) region of the ribosomal operon, PCR fingerprinting and amplified fragment length polymorphism (AFLP) analysis). Twenty‐four species or varieties investigated could be reduced to five taxa and were reclassified or synonymized as Trichophyton tonsurans, T. interdigitale, T. mentagrophytes, T. simii and T. erinacei.

SummaryBackgroundTrichophyton (T.) erinacei is a rare but emerging zoonotic dermatophyte that is rarely isolated as a human pathogen, with only a few cases extensively described in the literature.Patients and MethodsWe conducted a systematic search to identify eligible articles reporting demographics, clinical characteristics, and the therapeutic approach regarding T. erinacei infection in humans.Results168 patients affected by T. erinacei were reported in the international literature between inception and November 2023. Only 56 cases (32.1%) were fully described. The median age at diagnosis was 26 years, the female/male ratio was around 2:1. The main source of the disease was the hedgehog. The infection presented with a combination of erythema, scaly plaques, pustules, papules, vesicles, oedema, and erosion; the most common locations were the hands and the head. The most frequently conducted examination was fungal culture, but gene sequencing and mass spectrometry improved both speed and precision in the most recent diagnostic course. Topical clotrimazole and systemic terbinafine were the most chosen treatment.ConclusionsTrichophyton erinacei should be considered in patients with erythematous scaly patches and recent contact with hedgehogs. Terbinafine should be considered as a first‐line effective treatment, griseofulvin and azoles could be considered valid alternatives.
