Trogia venenata, [1] also known as the little white mushroom, [2] is a species of fungus in the family Marasmiaceae indigenous to Yunnan province, in southwest China. Consumption is deadly for both humans and mice, as the mushroom contains three toxic amino acids. [3]

This is the presumed cause of Yunnan sudden death syndrome.

In December 2012 it was announced that Dr. Xu Jianping (徐建平) has been collecting samples of Trogia venenata in Yunnan for the past three years, and his research now shows that barium (previously thought to be the cause) levels in the wild mushroom are no higher than those of common foods such as poultry and fish. [4]

Nonetheless, it appears the mushroom will still likely play a role. Since publication of the widely circulated 2010 Science article, no instances of Yunnan sudden death syndrome have been reported.

The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.

<span class="mw-page-title-main">SARS-CoV-1</span> Virus that causes SARS

Severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1), previously known as severe acute respiratory syndrome coronavirus (SARS-CoV), is a strain of coronavirus that causes severe acute respiratory syndrome (SARS), the respiratory illness responsible for the 2002–2004 SARS outbreak. It is an enveloped, positive-sense, single-stranded RNA virus that infects the epithelial cells within the lungs. The virus enters the host cell by binding to angiotensin-converting enzyme 2. It infects humans, bats, and palm civets. The SARS-CoV-1 outbreak was largely brought under control by simple public health measures. Testing people with symptoms, isolating and quarantining suspected cases, and restricting travel all had an effect. SARS-CoV-1 was most transmissible when patients were sick, so its spread could be effectively suppressed by isolating patients with symptoms.

<i>Triplophysa</i> Genus of fishes

Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.

<i>Amanita exitialis</i> Species of fungus

Amanita exitialis, also known as the Guangzhou destroying angel, is a mushroom of the large genus Amanita. It is distributed in eastern Asia, and probably also in India where it has been misidentified as A. verna. Deadly poisonous, it is a member of section Phalloideae and related to the death cap A. phalloides. The fruit bodies (mushrooms) are white, small to medium-sized with caps up to 7 cm (2.8 in) in diameter, a somewhat friable ring and a firm volva. Unlike most agaric mushrooms which typically have four-spored basidia, the basidia of A. exitialis are almost entirely two-spored. Eight people were fatally poisoned in China after consuming the mushroom in 2000, and another 20 have been fatally poisoned since that incident. Molecular analysis shows that the species has a close phylogenetic relationship with three other toxic white Amanitas: A. subjunquillea var. alba, A. virosa and A. bisporigera.

Yunnan sudden death syndrome is a sudden unexplained death from cardiac arrest, which afflicted significant numbers of rural villagers in Yunnan province in southwest China. Cases almost always occurred during the midsummer rainy season, at an altitude of 1,800–2,400 m (5,900–7,900 ft). An estimated 400 deaths occurred over three decades.

Bat SARS-like coronavirus WIV1, also sometimes called SARS-like coronavirus WIV1, is a strain of severe acute respiratory syndrome–related coronavirus (SARSr-CoV) isolated from Chinese rufous horseshoe bats in 2013. Like all coronaviruses, virions consist of single-stranded positive-sense RNA enclosed within an envelope.

Tropoflavin, also known as 7,8-dihydroxyflavone, is a naturally occurring flavone found in Godmania aesculifolia, Tridax procumbens, and primula tree leaves. It has been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF). Tropoflavin is both orally bioavailable and able to penetrate the blood–brain barrier. A prodrug of tropoflavin with greatly improved potency and pharmacokinetics, R13, is under development for the treatment of Alzheimer's disease.

SHC014-CoV is a SARS-like coronavirus (SL-COV) which infects horseshoe bats. It was discovered in Kunming in Yunnan Province, China.

The line of Rs3367 that infected human cells was named Bat SARS-like coronavirus WIV1.

Civet SARS-CoV is a coronavirus associated with severe acute respiratory syndrome coronavirus (SARS-CoV), which infected humans and caused SARS events from 2002 to 2003. It infected the masked palm civet. The severe acute respiratory syndrome coronavirus (SARS-CoV) is highly similar, with a genome sequence similarity of about 99.8%. Because several patients infected at the early stage of the epidemic had contact with fruit-eating Japanese raccoon dog in the market, tanuki may be a direct source of human SARS coronavirus. At the end of 2003, four more people in Guangzhou, China, were infected with the disease. Sequence analysis found that the similarity with the tanuki virus reached 99.9%, and the SARS coronavirus was also caused by cases of tanuki transmission.

Like SARS-CoV and SARS-CoV-2, LYRa11 virus uses ACE2 as a receptor for infecting cells.

<i>Cordyceps gunnii</i> Species of fungus

Cordyceps gunni is a species of fungus in the family Cordycipitaceae, and is of the genus Cordyceps. It was originally found and recorded by Gunn in Tasmania and named as Sphaeria gunnii and later moved into the Cordyceps genus and renamed Cordyceps gunnii. This fungus and its sisters in the genus Cordyceps are known for growing out of insect bodies. C. gunnii can be found at ground level poking out of caterpillar burrows, attached to a caterpillar's head.

<i>Isaria cicadae</i> Species of fungi

Isaria cicadae is an ascomycete fungus that parasitizes cicada larvae. It forms white and yellow asexual fruiting structures resembling synnema. While mostly being found throughout Asia in warm, humid regions, it has been found on various other continents. It is known in Traditional Chinese Medicine as Chan Hua and commonly called “cicada flower.” Its medicinal uses date back to the fifth century AD in China. It can also be used in various foods and tonics.
