Mucor circinelloides

Mucor circinelloides

Emerging Pathogen, Spore Former, Yeast/Fungus

STRUCTURE AND PHYSIOLOGY

Mucor circinelloides is a fungus commonly found in soil and food. M. circinelloides is described to exhibit dimorphism as it is found to grow in either filamentous mycelia or multipolar budding yeasts, depending on its environment. This microorganism reproduces asexually using sporangiophores and thrives in cooler temperatures.

TRANSMISSION AND DISEASE

M. circinelloides has not been commonly associated with disease in humans in the past, but it is now considered an emerging pathogen and linked to infections of the skin and in patients with other comorbidities.

NOTES

This fungus is found worldwide in soil, dung, and root vegetables. Mucor circinelloides are not known to produce mycotoxins. This fungus is considered an emerging pathogen, although it has only been associated rarely with human disease and has been limited to cutaneous infection
