One Health aspects & priority roadmap for fungal diseases : A mini-review.

Indian J Med Res 2021 Mar;153(3):311-319

Department of Medical Microbiology; Center of Advanced Research in Medical Mycology, Postgraduate Institute of Medical Education & Research, Chandigarh, India.

Fungal diseases have not been taken seriously in public health agendas as well as research priorities, despite of globally causing an estimated two million deaths every year, and the emergence of many troublesome fungal pathogens like Candida auris, azole resistant Aspergillus fumigatus, terbinafine and azole resistant dermatophytes, and zoonotic sporotrichosis in humans. Fungi are also responsible for huge losses of agricultural products and stored crops as well as recent massive and unexpected mortality in animals caused by white-nose syndrome in the bats and Chytridiomycosis in amphibians. This review aims to underscore the need for collaborative, multisectoral, and trans-disciplinary approach to include the One Health approach as an essential component of surveillance, prevention, and control of globally emerging fungal diseases.

CD4 T cells apoptosis and conversion of Th1/Th2-type cytokines promote the progress of sporotrichosis.

Dermatol Ther 2021 03 1;34(2):e14720. Epub 2021 Feb 1.

Department of Dermatology, The Second Hospital of Jilin University, Changchun, China.

Sporotrichosis is a fungal disease of the human and other mammals, caused by a complex of Sporothrix schenckii. The disease follows the traumatic inoculation to lead to fixed lesions, regional lymphangitic lesions, or even disseminated lesions including internal involvement, which depends on host immunological status and strain virulence. In this work, we observed the role of CD4 T cells apoptosis and conversion of Th1/Th2-type cytokines in the cellular immunity regulation on mice model sporotrichosis. Read More
