What is Chondrostereum purpureum?

April 5, 2023

A recent case report published in Medical Mycology Case Reports revealed that a man in Kolkata, India, was infected with Chondrostereum purpureum, a plant fungus. This discovery has raised concerns about the potential risks of fungal infections in humans, especially in the context of global warming.

The Case of Chondrostereum Purpureum Infection in a Man

The infected man exhibited symptoms such as hoarse voice, cough, fatigue, and difficulties swallowing. These symptoms were caused by the fungus invading the man’s larynx, which made it difficult for him to speak and swallow. The doctors who treated the patient noted that this was a rare case and that there are only a few fungal species that cause infections in humans.

Chondrostereum Purpureum and Silver Leaf Disease in Plants

Chondrostereum purpureum is a fungus that causes silver leaf disease in plants, especially in species of rose families. The fungus enters the plant through a wound and then colonizes the xylem tissue, leading to leaf discoloration and leaf death. The silver leaf disease can be detrimental to the growth and health of plants, and can also cause economic losses for farmers.

The Vulnerability of Humans to Fungal Infections

Human beings having compromised immune system are most susceptible to fungal infection. Fungal infections can also occur in healthy individuals, but they are generally less severe. The recent case of Chondrostereum purpureum infection in a man highlights the potential risks of fungal infections in humans, especially in the context of rising atmospheric temperature.

Global Warming and Fungal Infections

Global warming is expected to increase the prevalence of fungal diseases in humans. Most fungi thrive in a temperature range of 12°C to 30°C, and rising temperatures can change the distribution of heat-tolerant and susceptible species by favoring those that are more thermotolerant. This narrowing of the thermal difference between the human body and its surroundings increases the chance of the prevalence of fungal diseases.
