Abstract
A description is provided for Nannizzia fulva. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded only from man (but see NOTES). Guinea-pigs have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). Nannizzia fulva is present in the soil and apparently only rarely pathogenic. The scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Skin lesions are inflammatory. The only proved case of scalp infection is that recorded by Uriburu (1909); according to Sabouraud (Les Teignes, 1910, p. 241) in this case there was a light inflammatory reaction and infected hairs were indistinguishable from those in M. audouinii infections. In experimental inoculations of guineapigs (Rdzanek, pers. comm.) N. fulva was slightly less virulent than N. gypsea and N. incurvata, the reaction varying from negative to strongly inflammatory. A few ectothrix hyphae breaking up into arthrospores were seen on some hairs, and infected hairs did not fluoresce under Wood's light. GEOGRAPHICAL DISTRIBUTION: Africa (Tanzania), Europe (Great Britain, Hungary, Yugoslavia), South America (Argentina). Probably world-wide in distribution in the soil, but there may be local limiting factors (e.g., in Great Britain it has been recorded only for Bristol, Somerset, and Wiltshire).
