What is a fungal infection?
What is fungal infection? Fungal infections can affect anyone, and they can appear on several parts of the body. A jock with athlete’s foot, a baby with thrush, and a woman with a vaginal yeast infection are just a few examples. Fungi are microorganisms characterized by a substance in their cell walls called chitin.

If you think you have a fungal infection, see your doctor. They can diagnose the type of infection and recommend an appropriate antifungal medication. In some cases, your doctor may also recommend changes to your diet or other daily habits to help treat or prevent future fungal infections.
Why don t antibiotics work on fungal infections?
Fungi include yeasts, which grow as spherical cells; and molds, which grow as elongated, tubular cells. Both yeasts and molds are more closely related genetically to humans than they are to bacteria. Therefore, it is hard to develop antibiotics that attack fungi without damaging human cells.
Do antibiotics make fungal infections worse?
This in turn underscores the importance of careful stewardship of available antibiotics. Lead author Dr Rebecca Drummond said: "We knew that antibiotics make fungal infections worse, but the discovery that bacterial co-infections can also develop through these interactions in the gut was surprising.
Why are viruses difficult targets for selective drug treatment?
Compared to other pathogens, such as bacteria, viruses are minuscule. And because they have none of the hallmarks of living things — a metabolism or the ability to reproduce on their own, for example — they are harder to target with drugs.
What is selective toxicity and why is it important?
Treating Infections: Selective Toxicity The aim of antimicrobial therapy is to kill or inhibit the infecting organism without damaging the host; this is known as selective toxicity. This is commonly accomplished through the use of antimicrobial drugs.
Why is it more difficult to treat fungal infections than bacterial infections in humans?
In humans, fungal infections are less common than those caused by bacteria, but can be stubborn and difficult to treat - in part, because fungi are far more closely related to animals, including humans, than are bacteria. That limits the types of medical treatments that can be used against them.
How does fungi become resistant to antibiotics?
Fungi, like bacteria, can develop antibiotic resistance, when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. Antifungal resistance occurs when fungi no longer respond to antifungal drugs.
Why are fungal and protozoan infections so hard to treat?
Because fungi, protozoans, and helminths are eukaryotic organisms like human cells, it is more challenging to develop antimicrobial drugs that specifically target them. Similarly, it is hard to target viruses because human viruses replicate inside of human cells.
Why are diseases caused by viruses often very difficult to treat?
Viruses pose a considerable challenge to the body's immune system because they hide inside cells. This makes it difficult for antibodies to reach them.
Why is it more difficult to develop drugs to treat infections caused by eukaryotic microbes?
Eukaryotic microbial pathogens can exhibit drug resistance through reducing the overall intracellular concentration of the drug (less uptake, more efflux), by inactivating or failing to activate the drug, or by sequestering the drug away from its target.
Why are there fewer antifungal drugs compared to antibacterial drugs?
Antifungal drugs are relatively difficult to develop compared to antibacterial drugs owing to the eukaryotic nature of the cells. Only a few classes of antifungal drugs, such as polyenes, azoles, echinocandins, allylamines, and flucytosine, are available to treat the myriad of fungal infections (Sanglard et al., 2009).
What does selective toxicity mean in regards to how antibiotics work?
An important quality for an antimicrobial drug is selective toxicity, meaning that it selectively kills or inhibits the growth of microbial targets while causing minimal or no harm to the host.
Why are helminths fungi and protozoa pathogens difficult to treat with antimicrobial agents?
Because fungi, protozoans, and helminths are eukaryotic organisms like human cells, it is more challenging to develop antimicrobial drugs that specifically target them. Similarly, it is hard to target viruses because human viruses replicate inside of human cells.
