Rhizopus

Rhizopus is a genus of common saprophytic fungi, encompassing several species. It is part of the family Rhizopodaceae, and is known for its fast growth and widespread distribution. Rhizopus species are often the first colonizers of organic material, and are important in the decomposition process.

Characteristics

Rhizopus species are characterized by their hyphae, which are non-septate and coenocytic. They produce sporangia, which are spherical and borne on a columella. The sporangia contain numerous non-motile spores, which are dispersed by wind or water.

Species

There are several species of Rhizopus, including:

• Rhizopus stolonifer: Also known as the black bread mold, it is a common species that is often used in research.
• Rhizopus oryzae: This species is used in the production of traditional Asian fermented foods.
• Rhizopus microsporus: This species can cause human disease, particularly in immunocompromised individuals.

Pathogenicity

Some Rhizopus species can cause disease in humans and other animals. The most common disease caused by Rhizopus is mucormycosis, a serious and often fatal fungal infection. Rhizopus infections are particularly dangerous for individuals with weakened immune systems, such as those with HIV/AIDS, cancer, or organ transplant recipients.

Treatment

Treatment for Rhizopus infections typically involves antifungal medications, such as amphotericin B and posaconazole. In severe cases, surgical debridement of infected tissues may be necessary.
