CONGRESS 2023 - The ringworm turns: The emergence of Trichophyton indotineae in the UK
Trichophyton indotinaea is a newly described species of dermatophyte that has emerged with the last 10 years in India, and some Middle Eastern countries. It causes tinea corporis and tinea cruris mainly (ringworm infection of the torso and groin) and can spread to the arms, legs and face. T. indotineae is also characterised by a reduced susceptibility or outright resistance to one of the commonly used and otherwise highly effective antifungals, terbinafine. While high levels of cases are seen in Indida, countries outside of India and the Middle East are now seeing imported cases and the UK is not alone. Working with colleagues in London we have identified signficant numbers of cases and are now understanding how difficult these infections are to treat, even with antifungals that the organism should be sensitive to. Lesions are only superficial, but are itchy and disfiguring, and often relapse after initial antifungal therapy. We are continuing to learn about the epidemiology, transmission, diagnosis and treatment of this emerging infection.
