Abstract: Sporothrix schenckii is one of the etiological agents of sporotrichosis, a fungal infection
distributed worldwide. Both, the causative organism and the disease have currently received limited
attention by the medical mycology community, most likely because of the low mortality rates associated
with it. Nonetheless, morbidity is high in endemic regions and the versatility of S. schenckii to
cause zoonosis and sapronosis has attracted attention. Thus far, virulence factors associated with this
organism are poorly described. Here, comparing the S. schenckii genome sequence with other medically
relevant fungi, genes involved in morphological change, cell wall synthesis, immune evasion,
thermotolerance, adhesion, biofilm formation, melanin production, nutrient uptake, response to stress,
extracellular vesicle formation, and toxin production are predicted and discussed as putative virulence
factors in S. schenckii.
