It is the most common type of fungus to cause yeast infections. Sometimes, other types of candida fungus are to blame.
Candidiasis Yeast Infection Overview. A yeast infection results from an overgrowth of yeast (a type of fungus) anywhere in the body. Candidiasis is by far the most common type of yeast infection. There are more than 20 species of Candida, the most common being Candida albicans. These fungi live on all surfaces of our bodies Background. Cutaneous candidiasis and other forms of candidosis are infections caused by the yeast Candida albicans or other Candida species. Yeasts are unicellular fungi that typically reproduce by budding, a process that entails a progeny pinching off of the mother cell.  Candida albicans is the most common type of fungus to cause yeast infections. Sometimes, other types of candida fungus are to blame. Common treatments usually cure a Candida albicans infection. Yeast infections caused by other types of candida fungus can be more difficult to treat, and need more aggressive therapies. A yeast infection might happen after certain sexual activities, especially oral-genital sexual contact Candida albicans is a fungus and similar to the yeast people use to make bread. However, this type of yeast can cause infection when it is able to grow out of control in the human body. There are over 40 different species of Candida Yeast (often misspelled Candita), however, only a handful are harmful to us.  Candida Albicans. Candida albicans is the most abundant and significant species that causes yeast infections, called candidiasis, in people. According to the journal “Clinical Infectious Diseases,” it is estimated that C. albicans accounts for about 50 percent of all invasive candidiasis episodes. Of all the Candida species, only six are frequently encountered with human infectio Photomicrograph of the fungus Candida albicans. Candidiasis is a fungal infection caused by yeasts that belong to the genus Candida. There are over 20 species of Candida yeasts that can cause infection in humans, the most common of which is Candida albicans. Candida yeasts normally live on the skin and mucous membranes without causing infection; however, overgrowth of these organisms can cause symptoms to develop. Invasive candidiasis is an infection caused by a yeast (a type of fungus) called Candida. Unlike Candida infections in the mouth and throat (also called “thrush”) or vaginal “yeast infections,” invasive candidiasis is a serious infection that can affect the blood, heart, brain, eyes, bones, and other parts of the body.  More than 20 types of Candida can cause infection with Candida albicans being the most common. Infections of the mouth are most common among children less than one month old, the elderly, and those with weak immune systems. Candidiasis is a fungal infection due to any type of Candida (a type of yeast). When it affects the mouth, it is commonly called thrush. Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. Other symptoms may include soreness and problems swallowing. Candidiasis is caused by infection with species of the genus Candida, predominantly with Candida albicans. Candida species are ubiquitous fungi that represent the most common fungal pathogens that affect humans. Candidiasis (see the image below) is a fungal infection caused by yeasts from the genus Candida. Candida albicans is the predominant cause of the disease. Soreness and cracks at the lateral angles of the mouth (angular cheilitis) are a frequent expression of candidiasis in elderly individuals. Candidiasis, often known in layman’s terms as  thrush , designates an infection caused by yeast of the genus Candida, with Candida albicans being the most common species responsible. Candida species are rarely found in environmental samples, being primarily associated with man or with warm blooded animals.
