Several months have passed since the first case of human infection with the fungus Chondrostereum purpureum was discovered in India in September 2023. While initial concern was high, the situation now appears more stable.
- No new cases of Chondrostereum purpureum infection have been reported since the initial case.
- Research into the fungus continues to better understand the risk of infection.
- The risk to human health appears to be limited, but caution is still required.
In September 2023, a Indian mycologist made a worrying discovery: a fungal infection by Chondrostereum purpureum, a fungus usually responsible for diseases in trees. This case, the first recorded in humans, triggered maximum alert in the scientific and medical community.
Chondrostereum purpureum, a mushroom with many facets
Chondrostereum purpureum, better known as “silver leaf fungus”, is a fungus commonly found on diseased or decaying trees. This saprophytic fungus feeds on decaying organic matter and plays an important role in the forest ecosystem. However, Chondrostereum purpureum can also be pathogenic to some trees. It is responsible for a disease called “parasitic lead”, which particularly affects fruit trees and causes them to die.
An unprecedented case of human infection
In September 2023, an Indian mycologist developed an abscess in his neck after being exposed to cultures of the fungus Chondrostereum purpureum. Tests revealed the presence of the fungus in the infected tissues, confirming the first case of human infection with this fungus.
Investigations are underway to understand the circumstances of the infection
Researchers are currently trying to understand the exact circumstances that led to the mycologist’s infection. It is possible that he inhaled fungal spores or came into direct contact with the fungus while working in the lab.
Although this case remains isolated, it nevertheless raises questions about the infectious potential of Chondrostereum purpureum for humans. Immunocompromised individuals could be particularly vulnerable to this type of infection.
Precautionary measures recommended
As a precaution, health authorities recommend that people working with fungi, particularly Chondrostereum purpureum, take precautionary measures to limit the risk of exposure, such as wearing masks and gloves. Further research is needed to better understand the mechanisms of Chondrostereum purpureum infection and to assess the actual risk to human health.
No new cases of infection have been reported since the initial case. This suggests that the risk of widespread infection is low.
Research into Chondrostereum purpureum continues. Scientists are seeking to better understand the mechanisms of infection, risk factors and means of prevention.
Precautionary measures remain recommended for people working with fungi, particularly Chondrostereum purpureum. These measures include wearing masks, gloves and protective glasses.
Based on current knowledge, Chondrostereum purpureum appears to pose a limited risk to human health. However, caution is still required and continued monitoring is necessary.
