“…The head of the hedgehogs has been previously described as the most frequent site of infection, while thorough sampling of the animal is also advised since other sites can also be infected [ 12 , 35 ]. We decided to sample animals under isoflurane anaesthesia using the carpet technique, which reduces the risk of underestimating the infection rates [ 12 ].…”

The rising number of European hedgehogs (Erinaceus europaeus) admitted every year to wildlife rehabilitation centres might be a source of concern to animal and public health since transmissible diseases, such as dermatophytosis, can be easily disseminated. This study seeks to evaluate the frequency of dermatophyte detection in hedgehogs admitted to a wildlife rehabilitation centre located near Paris, France, and to assess the risk of contamination in the centre in order to adapt prevention measures. A longitudinal cohort study was performed on 412 hedgehogs hosted at the Wildlife Animal Hospital of the Veterinary College of Alfort from January to December 2016. Animals were sampled once a month for fungal culture. Dermatophyte colonies were obtained from 174 out of 686 skin samples (25.4%). Besides Trichophyton erinacei, Trichophyton mentagrophytes and Nannizzia gypsea were also found. Dermatophyte detection seemed to be associated with the presence of skin lesions, while more than one-third of T. erinacei-positive animals were asymptomatic carriers. Healing required several months of treatment with topical and systemic azoles, but dermatophytosis did not seem to reduce the probability of release. Daily disinfection procedures and early detection and treatment of infected and asymptomatic carriers succeeded in limiting dermatophyte transmission between hedgehogs and humans.

“…mentagrophytes var. erinacei has been isolated in New Zealand, 4–6 the British Isles, 3,7–9 continental Europe, 10 and the Middle East, 11 and most recently from pet hedgehogs in Japan 12,13 . According to culture studies, 44.7% of wild hedgehogs in New Zealand 4 and 38.9% of pet hedgehogs in Japan 13 are contaminated with T. mentagrophytes var.…”

“… 17 Nucleotide sequence polymorphisms amongst T. mentagrophytes var. erinacei isolates are minimal, however, and their homology has been reported to be 99.7% 12 . Thus, sequence analysis is a highly reliable molecular marker for discriminating between T. mentagrophytes var.…”

International Journal of Dermatology 2005, 44 , 765-768 765A 26-year-old woman with no family history of dermatophytosis presented with pruritic erythema on the right palm ( Fig. 1) in November 2002, 1 month after first noticing it. She had no lesions on the soles, toe webs, left palm, or nails. The erythema had been treated with topical steroids for 4 weeks, but had continued to expand. The erythema measured 42 mm × 36 mm, and was hyperemic and infiltrated unevenly. Its center showed no signs of healing, its periphery exhibited small vesicles, and its margin showed scales. On the scales, fungal hyphae and chains of arthroconidia were revealed by direct KOH test. The erythema was diagnosed as tinea manuum and was treated with topical terbinafine once daily. After several days of treatment, the erythema flared up and red papuloerythemas appeared on the back of both hands and on both forearms.Ten days after the first visit, the patient returned to our clinic for the treatment of newly developed eruptions. A trichophytin skin test produced an infiltrated erythema measuring 21 mm × 18 mm, confirming that the newly developed eruptions and exacerbated erythema on the right palm were due to a trichophytid reaction. Topical terbinafine was continued for the palm and fluocinolone acetonide ointment was applied on the newly developed eruptions on the arms from day 10 after the first visit. All the inflammatory eruptions subsided after 4 weeks of treatment and direct KOH test results were negative.The suspected cause of tinea manuum was the patient's pet female four-toed hedgehog ( Atelerix albiventris ) which she had kept for 4 years (Fig. 2). When she bought it from a local pet shop, it had desquamation on its body, but no lesions with loss of hair or quill and no dermatitis.The scaling decreased gradually with treatment given by a veterinarian.Three isolates of dermatophytes were obtained from the scale on the woman's palm (KMU 4455), scale removed from the hedgehog (KMU 4459-1), and a fallen-out quill (KMU 4459-2).KMU 4455 grew rapidly with an ivory-white and lightly powdery surface, and with concentric ripples at the periphery. The center of the colonies was fluffy and elevated slightly, with a yellow pigment beneath (Fig. 3). The strains from the hedgehog were morphologically similar to each other, and their colonies grew more slowly and had a more powdery texture than those of KMU 4455. KMU 4459-1 and KMU 4459-2 gave a positive urease test result, whereas KMU 4455 gave negative results even at day 7 of incubation. The microscopic findings of the three isolates were almost the same (Fig. 4). Numerous teardrop-shaped microconidia were produced along the sides of the rectangle of mycelium. Spherical microconidia clustered in some parts and some club-shaped, 2 -6-roomed macroconidia were observed. There were some poorly developed macroconidia and some elongated microconidia which were so large that they were intermediate in size between normal microconidia and macroconidia. There was no spiral body.The isolates were mate...
