The origin of candida auricularis is still unclear, and it is not clear whether it is an environmental fungus or a human symbiotic fungus. Researchers generally believe that this is a newly evolved species with rapid adaptation to human host environment. It mainly causes blood infection with a lethal rate of 60%.
“Up to now, China has confirmed 18 clinical cases of super fungus infection. The” super fungus “here refers to Candida auricularis. We are still monitoring it continuously, but on the whole there has not been an outbreak of epidemic infection like that in the United States. “
On April 8, Liao Wanqing, academician of the Chinese Academy of Engineering and professor of dermatology at the Long March Hospital of the Second Military Medical University, told China News Weekly.
The new york Times reported on April 6 that Icahn School of Medicine at Mount Sinai, new york City, discovered an “mysterious and deadly” fungus when performing abdominal surgery on an elderly man last May. The hospital quickly isolated him in an intensive care unit.
The man eventually died 90 days after hospitalization, but the deadly fungus survived tenaciously. Many parts of the ward were invaded, and the hospital specially disinfected the walls, sickbeds, doors, water tanks, telephones, and even removed some ceilings and floors.
At present, this multi-drug resistant fungus named Candida auricularis is prevalent in 12 states including new york, New Jersey and Illinois.

“Super fungi can live on the skin of patients and medical staff and the surface of hospital facilities for a long time. If infection control measures are not effective, it is easy to cause explosive infection in the hospital.”
Wang Hui, head of the Peking University Health Science Center Laboratory Department and director of the Peking University People’s Hospital Laboratory Department, said.
A common thermometer was the main culprit of the super fungal infection that broke out in England in 2018.
“Judging from the existing literature, most infected people will have high fever with unknown causes, ineffective treatment with various drugs, accompanied by various organ failure, respiratory failure and other manifestations.”
Liao Wanqing said. In 2018, the first clinical case of candida auricularis infection was found in China. The first candida auricularis strain in China was isolated from a 76-year-old patient. The research was jointly conducted by a team led by Huang Guanghua, a researcher from the State Key Laboratory of Mycology in Wang Hui and Institute of Microbiology, Chinese Academy of Sciences.
Since then, Shang hong, director of the laboratory department of the first affiliated hospital of China medical university, and his team have identified 15 hospitalized patients as infected with candida auricularis. According to Liao Wanqing, the Academy of Military Medical Sciences also identified 2 cases. “So far, 18 clinical cases of candida auricularis infection have been confirmed in mainland China, and we are still monitoring them continuously.”
The origin of candida auricularis is still unclear, and it is not clear whether it is an environmental fungus or a human symbiotic fungus.
Researchers generally believe that this is a newly evolved species with rapid adaptation to human host environment. It mainly causes blood infection with a lethal rate of 60%.
Under the microscope, candida auricularis has no obvious difference from other candida species, but it usually has multiple drug resistance. some strains have high drug resistance to the three major types of antifungal drugs commonly used in clinic.
This super fungus is most lethal to people with immature or damaged immune system, including newborns and the elderly, smokers, diabetics and patients with autoimmune diseases.
Recently, the U.S. Centers for Disease Control and Prevention (CDC) has placed Candida auricularis on the “emergency threat” list. According to the latest report on its website, the number of cases of infection in the United States has risen to 587, with nearly 50% of those infected dying within 90 days.
In 2017, the outbreak of candida auricularis occurred in 24 countries around the world, including Japan, the United States, Britain, Spain, India and other countries.
