Isolation of Potentially Pathogenic Fungi from Polluted Water and Sewage

D URING the last several years, increasing evidenece lhas accumulated that fungi po- tentially patlhogenic for man can be isolated from the enviroinmenit.Ajello (1, in tabular suimmary; and 2), Cooke (3), and Graystoni and Fuircolow (4) hiave reported the findinig of funigi whliclh are conisidered etiological agents of some of the deep-seated and the superficial inycoses of mrian, in habitats sticlh as natural and cultivated soils; wild aniimal burrows; soils un(ler nesting pllaces of bir-ds anid fowl; undis- turi-be(d portions of buildings, such as attics, Ibasemeints, and(I belfries whlere birds anid animals iest or roost; aind hlollow trees.A. lhabitat type recently tapped for the pres- ence of funglli, anild whlichl also is relatively rich in nitrogenouos compoun-ids, is sewage and pol-
