Oral Candidiasis
While most people carrying the fungus will go through life without ever learning the scientific name of their innocuous tenant, also called a “commensal”, some do encounter it as the common cause of oral thrush, nappy rash or vaginal yeast infections - Stephanie Diezmann

Clues to body's defense against common oral ailment
The mouth is home to a large number of microbes, termed commensals, which are harmless in healthy individuals. However, suppression of the immune system can lead to severe and reoccurring painful oral infections from these organisms, explained the study's co-senior author Sarah Gaffen, Ph.D., who holds the Gerald P. Rodnan Endowed Chair in the Division of Rheumatology & Clinical Immunology at Pitt.
One such example is the fungus Candida albicans. The harmless commensal form exists as a small single-celled organism, but when the immune system is compromised, Candida elongates into an invasive form, characterized by long filaments called hyphae, that causes a pervasive infection called…

What It's Like Having An AWFUL Yeast Infection ... In My Mouth
When I was 13 I got the worst yeast infection ever ... in my mouth and on my lips. Yep, because nothing makes being the weird 13-year-old in your eighth grade class who always wears an X-Files t-shirt even BETTER than a yeast infection in her mouth.
Enemy within: the fungus that lives in your mouth and kills as many as MRSA
On hearing the word “fungi” most people will probably think of pizza al funghi or a portobello mushroom burger. Incidentally, roughly half of the people salivating about these dishes will also carry a fungus called Candida albicans in their mouths or digestive tracts where it lives quietly, invisibly to the human eye, without causing disruptions or symptoms. But Candida albicans does not always go unnoticed. While most people carrying the fungus will go through life without ever learning the scientific name of their innocuous tenant, also called a “commensal”, some do encounter it as the common cause of oral thrush, nappy rush or vaginal yeast infections. Indeed, 75% of women will experience at least one episode of yeast infection throughout their lifetime.
Microbiologists discover possible new strategy to fight oral thrush
Traditional antifungals stop Candida albicans from growing, but do not kill it, which leads to the rise of drug resistance. In contrast, the EntV protein appears to block the ability of Candida to cause disease but does not affect its growth.
Oral candidiasis: An overview
Oral candidiasis is one of the common fungal infection, affecting the oral mucosa. These lesions are caused by the yeast Candida albicans. Candida albicans are one of the components of normal oral microflora and around 30% to 50% people carry this organism.
Oral Thrush - What Bumps on Your Tongue May Be Telling You
A minor infection on the tongue isn't uncommon. Bumps may even appear after an injury from a bite or irritation to some foods, for example hot foods. A canker sore is another common cause of pain on or under the tongue. But if you have large bumps at the back of your tongue, and a coating of white on your tongue it may be a sign of Oral Thrush.
Clues to body's defense against common oral ailment
The harmless commensal form exists as a small single-celled organism, but when the immune system is compromised, Candida elongates into an invasive form, characterized by long filaments called hyphae, that causes a pervasive infection called oral candidiasis, or "thrush." The immature immune systems of infants make them particularly susceptible to thrush, which can lead to a failure to thrive and nutritional deficiencies.
CDC
Candidiasis in the mouth, throat, or esophagus is uncommon in healthy adults. People who are at higher risk for getting candidiasis in the mouth and throat include babies, especially those younger than 1 month of age, and people with at least one of these factors...
KidsHeralth
Oral thrush (also called oral candidiasis) can affect anyone, but is most common in babies younger than 6 months old and in older adults. A baby with oral thrush might have cracked skin in the corners of the mouth or white patches on the lips, tongue, or inside the cheeks that look a little like cottage cheese but can't be wiped away. Some babies may not feed well or are uncomfortable when sucking because their mouth feels sore, but many babies don't feel any pain or discomfort.
MedicineNet
Thrush (oropharyngeal candidiasis) is a medical condition in which a yeast-shaped fungus called Candida albicans (the older and less often used name for Candida is Monilia) overgrows in the mouth and throat.
NHS
Low numbers of the fungus Candida are naturally found in the mouth and digestive system of most people. They don't usually cause any problems, but can lead to oral thrush if they multiply.
StatPearls
It was first described in 1838 by pediatrician Francois Veilleux. Oral candidiasis is generally obtained secondary to immune suppression, whether a patient's oral cavity has decreased immune function or if it is systemic.
