 PathogenicAssociation.

3. Weak and Fortuitous Association
 Aspergillus fumigatus Human pulmonary
system.
 Fusarium solani, Pseudallescheria boydii
Wounds and deep cracks of the skin.
Fusarium solani Aspergillus fumigatus Pseudallescheria sp

4.  Malassezia – present on skin or outer ear canals of the mammals.
 Candida species i.e C.albicans, C.tropicalis, C.glabrata – gastro
intestinal tracts/ normal skin.
Malassezia Candida albicans

5. Causal organism- Candida

6. Causal organism- Candida

7. Causal organism- Malassezia

8. Cutaneous Pathogens
 Sub- cutaneous pathogens.
 Ocular pathogens.
 Opportunistic pathogens.
Pathogenic Association

9.  They include skin infecting Dermatophytes
Arthoderma, Ajellomyces.
 Blastomyces dermatitidis causes Blastomycosis in
mammals.
 Penicillium marneffei causes hepatic lesions in Bamboo
rats and later it leads to death.
Cutaneous Pathogens

10.  Histoplasma capsulatum causes Lymphocutaneous
diseases in mammals.

11. Subcutaneous pathogens
 Associated by the pathogens Cladophialophora, Phialophora.
 Cladophialophora bantiana causes brain abscess , especially in
Humans.
 Acremonium falciforme and leptosphaeria senegalensis is a cause of
mycetoma.

12. Ocular Pathogens
 The mammalian eye presents a special habitat for large
number of fungal species implanted by plant debris.
 Fusarium solani is the comman cause of Blindness in the
mammals.
 Reptiles is also effected.

13. Opportunistic Pathogens
 Aspergillus fumigatus causes pulmonary disease especially
in fowls, penguins and other birds.
 Cryptococcus neoformans causes Cryptococcal Meningitis.

14. Conclusion
 Fungal associates with vertebrates by commensal,
Pathogenic , weak and fortuitous association.
 Association may be beneficial for the fungi but most
of the times it is a problematic to the vertebrates.
