CHAPTER XXXII 



Characteristics of Pathogenic Fungi 



THE list of fungi which follows includes those which seem to be most 

 important from the practical standpoint. It is by no means complete. 

 Davidson and Gregory stated that at least 180 species of dermatophytes 

 have been mentioned in the literature as pathogenic for man. The majority 

 of these species have been isolated only once or only a few times, so they 

 may safely be ignored. In other parts of the United States and in foreign 

 countries the flora may vary somewhat, and some micro-organisms which 

 we rarely see in New York may elsewhere be of more common occurrence. 

 Brief data on the clinical aspects and sensitization phenomena of the 

 species of fungi are included with the descriptions of their microscopic 

 and cultural characteristics. Further clinical information is available in 

 Part One, where the various mycoses which they cause are described. 

 The following fungi will be described in detail: 



1. Microsporum audouini 



2. Microsporum lanosum 



3. Microsporum fulvum 



4. Microsporum ferrugineum 



5. Achorion schoenleini 



6. Trichophyton alba (faviforme) 



7. Trichophyton violaceum 



8. Trichophyton crateriforme 



9. Trichophyton sulfureum 



10. Trichophyton gypseum 



11. Trichophyton purpureum 



12. Epidermophyton inguinale 



13. M on ilia albicans 



14. Malassezia furfur 



15. Actinomyces minutissimus 



16. Endodermophyton tropicale
