1 One Tiny Mold, One Big Problem: Aspergillosis
By: Melanie Yodock

2 Outline History of Aspergillosis Aspergillus species information
People at Risk Clinical Types Detection/Diagnosis Treatment

3 History First noted in 1815 Secondary infection
Associated with certain occupations

4 Aspergillus sp. Taxonomy Morphology Named after aspergillum
species species species 5 common species Many rarer species Morphology Saprophytes Small, fluffy, white colonies Pathogenic species can be different colors

5 People at Risk AIDS patients Neutropenia Chronic Granulomatous Disease
Solid Organ Transplant Recipients Hematopoietic Stem Cell Transplant Recipients (HSCT)

6 Clinical Cases Pulmonary Aspergillosis Aspergillomas
Granulomatous aspergillosis

7 Clinical Cases Cont. Otomycosis Aspergillus Sinusitis

8 Clinical Cases Cont. Tracheobronchitis Cutaneous Aspergillosis

9 Clinical Cases Cont. Cerebral Aspergillosis

10 Detection/Diagnosis BAL cultures (1→3)-β-ᴅ-glucan assay

11 Detection/Diagnosis CT scans Laboratory Markers and PCR

12 Treatment Amphotericin B Voriconazole Itraconazole Caspofungin
Posaconazole

13 Summary Aspergillosis has been around for hundreds of years
Secondary infection in immunocompromised patients Many clinical types of aspergillosis New detection techniques are allowing for earlier diagnosis Many treatment options but an ongoing battle with fungal evolution and resistance
