A high incidence od endemic tinea capitis was found among children at the Aboriginal settlement of Maningrida, Arnhem Land, on the northern coast of Australia some 400 km east of Darwin. The cause was a variant of Microsporum canis which will be referred to as the‘Maningrida’type. It was isolated form 21 (25.3%) brush samples taken form the scalps of 83 Aboriginal Children. There were diffuse, or scattered fine white scaling lesions with minimal hair loss. Clinically these infections could not be distinguished from endothrix tinea capitis caused by Trichophyton tonsurans or Trichophyton violaceum which occur frequently in Aboriginal children in South Australia. No cases of endothrix tinea catitis were found in Aboriginal children in Darwin or in the other settlements which were visited in Arnhem Land. The‘Maningrida’type of M. canis developed as a small spidery colony with a central downy to powdery fuftm which in five to six days produced many typical macroconidia. Young cultures Produced little or no pigment, but later developed a buff or pale brownish pigment. Four cats and two dogs at maningrida were shown to be reservoirs of the variant of M. Canis. No Strains of the typical M. canis with its golden yellow pigment were isolated at maningrida.
