Antibodies to dermatophytes (M. audouinii, T. mentagrophytes var. granulosum and var. interdigitale, T. rubrum, and T. tonsurans) were detected in sera of patients with tinea capitis and tinea corporis by charcoal agglutination tests, immunodiffusion analysis, and complement fixation tests. In tinea capitis, these antibodies were not confined to patients with deep-seated, inflammatory infections. The zoophilic variety of T. mentagrophytes induced antibody formation more frequently than the anthropophilic variety in patients with tinea corporis. Precipitating and complement-fixing antibodies were often found in sera of patients with chronic T. rubrum infections. The agglutinating, precipitating, and complement-fixing antibodies persist for a limited period of time only; therefore, the time in the course of the infection at which blood is taken is of utmost importance for the study of circulating antibodies.

“…Alternate theories to explain our findings include a change in the virulence of Microsporum with resultant loss of its ecologic niche; however, there is no proof supporting a change in virulence.

However, since griseofulvin had been in use for some years prior to this study, this seems unlikely as an explanation for the relatively recent disappearance of Microsporum tinea capitis.…”

From 1962 to 1979, there was a dramatic change in tinea capitis infections in children in the Philadelphia area. This has been primarily due to the virtual disappearance of tinea capitis due to Microsporum organisms. This dramatic change in a common, highly infectious childhood disease is most likely due to a sudden change in hair styles, particularly in black boys, which prevents infectious spores from reaching the scalp.

“…This organism was responsible for causing epidemic tinea capitis in most of the major cities in the United States during the forties and fifties. The incidence of M. audouinii in the Philadelphia area was 40% in 1966 [2] and 20% in 1974 [3], There are no reports in the San Francisco Bay Area or in California to which these results can be compared. The two Philadelphia studies have demonstrated that M. audouinii has decreased from 40% (1966) to 20% (1974), but has not disappeared [2,3],…”

A total of 1,101 patients was studied for the incidence and distribution of dermatophytes in the San Francisco Bay Area from 1974 to 1978. 267 dermatophytes were isolated and identified. Trichophyton rubrum and Triehophyton tonsurans were the most prevalent dermatophytes. T. rubrum caused 83% of tinea pedis, 82% of tinea unguium, 80% of tinea manuum and 66% of tinea cruris. T. tonsurans was the major cause of tinea capitis (60%) followed by Microsporum canis. Microsporum audouinii was not encountered in this survey.
