Both of these structures surround and protect the fungal cell. When either one becomes compromised, the fungal cell can burst open and die. Antifungal drugs are very diverse.
They can be given orally, as a topical treatment, or via IV. How an antifungal drug is given depends on factors like the specific drug, the type of infection you have, and the severity of your infection. Antifungal drugs are classified by their chemical structure as well how they work.
Azoles are some of the most commonly used antifungals. Because of this, the cell membrane becomes unstable and can leak, eventually leading to cell death. Polyenes kill fungal cells by making the fungal cell wall more porous, which makes the fungal cell prone to bursting.
One example of an allylamine is terbinafine, which is often used to treat fungal infections of the skin. Echinocandins are a newer type of antifungal drug. There are also some other types of antifungal medications. Flucytosine is an antifungal that prevents the fungal cell from making nucleic acids and proteins.
Because of this, the cell can no longer grow and thrive. Flucytosine can be used to treat systemic infections with Candida or Cryptococcus species. Griseofulvin works to prevent the fungal cell from dividing to produce more cells.
It can be used to treat infections of the skin, hair, and nails. There are many types of fungal infection. You can get a fungal infection by coming into contact with a fungus or fungal spores that are present in the environment.
Some of the most common fungal infections are those of the skin, nails, and mucous membranes. Examples include:. There are also some less common but more serious fungal infections that can cause fungal pneumonia , fungal meningitis , or even systemic infections.
People who may have weakened immune systems include those who are:. Antifungal drugs are used to treat fungal infections. They target processes and structures unique to fungi in order to kill fungal cells or prevent them from growing. There are many types of antifungal drugs, and they can be given in several different ways.

For these organisms, fungi present a major threat. Outbreaks of fungal diseases such as white nose syndrome in bats, and chytridiomycosis in frogs, toads, and salamanders, have caused millions of deaths within the past few years.
These mass extinctions cause potentially harmful perturbations to the ecosystems in which these animals live and contribute to loss of biodiversity.
White nose syndrome is caused by a cool-temperature loving organism, Pseudogymnoascus destructans , which flourishes between 4—20º Celsius. When bats hibernate in winter, their body temperatures cool, allowing the fungi to grow and causing distinctive fuzzy, white patches to develop on their noses, ears, and wings.
In the United States, the disease first appeared in the northeast in , and is gradually spreading west. Bats are important pollinators and predators of insect species, and this steep decline in the bat population will create disturbances in ecological balance.
Currently, there is no widespread, approved treatment for the disease, but decontamination efforts are underway, as well as a potential therapy using a strain of Rhodococcus bacteria , and potentially, a natural solution—as chubby bats are more likely to survive the disease in endemic areas.
Fungi also threaten human health indirectly by infecting and damaging food crops. Magnaporthe is a well-known "plant-destroyer," but a number of fungal species have contributed to famines, blight, and economic turmoil.
In addition to killing crops, fungal growth can lead to mycotoxin contamination of crops, rendering them inedible.
The Colloquium report supports additional research on new methods for controlling fungal infections in plants and crops, including gene-silencing techniques using small RNAs sRNAs , a type of short, non-coding RNA that can regulate gene expression. One proposed sRNA method relies on a transgenic plant variant that expresses virulence gene silencing sRNAs that provide the ability to block expression of fungal virulence factors from a variety of fungal species that promote infection.
sRNAs are prevalent in plants, as well as invading pathogens, and function as a communication system between host and microbe.
Many sRNAs are components of the plant immune system and can thereby be used to confer specific immunity to fungal pathogens. Potential advantages of this system include the fact that the sRNA genes are heritable, can be spread between organisms, and can target multiple fungal targets simultaneously.
An alternative method for silencing fungal virulence genes in plants proposes the use of a spray-on double-stranded naked RNA dsRNA or sRNA that can be applied directly to plants.
This approach applies a concept known as environmental RNAi , wherein organisms can take up exogenous RNA. Botrytis cinerea , the common gray mold you may have seen enveloping old strawberries and grapes, can take up externally applied RNAs.
RNAi has already been used successfully to modifiy crops and prevent food waste: the FDA approved apples that do not turn brown and potatoes that produce less of the toxin compound, acrylamide, back in Several researchers and biotech industry partners are working to make RNAi-based gene silencing technologies a reality, and some estimate that spray-on RNAi pesticides will be available within the next 5 years.
The exact reasons why fungi have been historically understudied and largely left out of the microbial conversation are complex, but it is evident that fungi demand our immediate attention, as numerous fungi-related problems are emerging that require action to preserve our planet.
Fungi are an important and challenging cause of infectious disease across species, populations and ecosystems. The Colloquium Report aims to redirect our focus and inspire greater interest in understanding the changing role of fungi and how they fit into many cutting-edge scientific issues, from exploring the human microbiome to preventing global warming.
Fungi and fungal research will be critical in determining the future of environmental sustainability and public health. Love fungi? Check out The Fungal Kingdom from ASM Press.
