Histoplasmosis Genotyping in Dog and Cats

Phylogenetic classification of Histoplasma capsulatum causing histoplasmosis in pet dogs and cats



To collect a sample of Histoplasma organisms from dogs and cats, for fungal culture and then genotyping to determine the phylogenetic classification of the Histoplasma. 

Clinical Protocol:

Either a blood sample or organ aspirate (such as liver, spleen, node, skin or lung) will be collected for culturing from dogs or cats already diagnosed with histoplasmosis. If Histoplasma organisms are successfully cultured from this sample, isolates will be genotyped and tested for antifungal susceptibility. Once the antifungal results are available, they will be shared with the owner.

Enrollment Criteria:

Any dog or cat previously diagnosed with histoplasmosis

What does enrollment into this trial involve?

This study requires only one visit to the VHC for exam and blood and/or organ aspirate collection from dogs and cats previously diagnosed with histoplasmosis.

Treatment with antifungal medications is not included in the study.

For dogs and cats that have suspected histoplasmosis, but have not had diagnosis confirmed, there is currently another trial offering histoplasmosis testing here.

Client Compensation:

This study covers the cost of fungal culturing, genotyping, and antifungal susceptibility testing.  Fees for other diagnostic testing and antifungal treatment will be the responsibility of the owner.
