Candida yeasts are commonly present in most people, but uncontrolled multiplication resulting in disease symptoms is kept in check by other naturally occurring microorganisms, e.g., bacteria co-existing with the yeasts in the same locations, and by the human immune system.
In a study of 1009 women in New Zealand, C. albicans was isolated from the vaginas of 19% of apparently healthy women. Carriers experienced few or no symptoms. However, external use of irritants (such as some detergents or douches) or internal disturbances (hormonal or physiological) can perturb the normal flora, constituting lactic acid bacteria, such as lactobacilli, and an overgrowth of yeast can result in noticeable symptoms. Pregnancy and the use of oral contraceptives have been reported as risk factors, while the roles of engaging in vaginal sex immediately and without cleansing after anal sex and using lubricants containing glycerin remain controversial. Diabetes mellitus and the use of antibiotics are also linked to an increased incidence of yeast infections. Diet has been found to be the cause in some animals; Hormone Replacement Therapy and infertility treatments may also be predisposing factors.
A weakened or undeveloped immune system or metabolic illnesses such as diabetes may predispose individuals to candidiasis. Diseases or conditions linked to candidiasis include HIV/AIDS, mononucleosis, cancer treatments, steroids, stress, and nutrient deficiency, among many others. Almost 15% of people with weakened immune systems develop a systemic illness caused by Candida species. In extreme cases, these superficial infections of the skin or mucous membranes may enter into the bloodstream and cause systemic Candida infections.
Antibiotic and steroid use are the most common reason for yeast overgrowth. The former kills the bacteria which would otherwise help maintain Candida at safe levels, thus allowing the fungus to overgrow.
In penile candidiasis, the causes include sexual intercourse with an infected party, low immunity, antibiotics, and diabetes. Male genital yeast infection is less common, and the risk of getting it is only a fraction of that in women; however, yeast infection on the penis from direct contact via sexual intercourse with an infected partner is not uncommon
Symptoms include severe itching, burning, and soreness, irritation of the vagina and/or vulva, and a whitish or whitish-gray discharge, often with a curd-like appearance. Many women mistake the symptoms of the more common bacterial vaginosis for a yeast infection. In a 2002 study published in the Journal of Obstetrics and Gynecology, only 33 percent of women who were self-treating for a yeast infection actually had a yeast infection, while most had either bacterial vaginosis or a mixed-type infection instead.
In men, symptoms include red patchy sores near the head of the penis or on the foreskin, severe itching, and/or a burning sensation. Candidiasis of the penis can also have a white discharge, although uncommon. However, having no symptoms at all is common, and usually, a more severe form of the symptoms may emerge later.
Medical professionals may use two primary methods to diagnose yeast infections: microscopic examination and culturing.
For identification by light microscopy, a scraping or swab of the affected area is placed on a microscope slide. A single drop of 10% potassium hydroxide (KOH) solution is then added to the specimen. The KOH dissolves the skin cells but leaves the Candida cells intact, permitting visualization of hyphae and yeast cells typical of many Candida species.
For the culturing method, a sterile swab is rubbed on the infected skin surface. The swab is then streaked on a culture medium. The culture is incubated at 37 °C for several days, to allow development of yeast or bacterial colonies. The characteristics (such as morphology and colour) of the colonies may allow initial diagnosis of the organism that is causing disease symptoms.
It is important to consider that Candida species are frequently part of the human body's normal oral and intestinal flora. Treatment with antibiotics can lead to eliminating the yeast's natural competitors for resources, and increase the severity of the condition.
In clinical settings, candidiasis is commonly treated with antimycotics—the antifungal drugs commonly used to treat candidiasis are topical clotrimazole, topical nystatin, fluconazole, and topical ketoconazole. For example, a one-time dose of fluconazole (as Diflucan 150-mg tablet taken orally) has been reported as being 90% effective in treating a vaginal yeast infection. This dose is only effective for vaginal yeast infections, and other types of yeast infections may require different treatments. In severe infections (generally in hospitalized patients), amphotericin B, caspofungin, or voriconazole may be used. Local treatment

What is a yeast infection: A yeast infection is exactly that -- an infection caused by yeast. It's called candidiasis and it can happen in any number of places in or on the body.
How do you get one: Vaginal candidiasis occurs in the vagina when the normal microorganisms that are present become out of balance. The organisms normally found in the vagina are called "resident flora" and these include yeast, a type of fungus, and bacteria. The flora control each other's numbers so no one flora gets out of control. When great numbers of bacteria are killed off, such as during antibiotic therapy, the numbers of yeast, usually a type called Candida albicans, get out of control and caused infection. Then you have candidiasis.
Canesten (note spelling): It's a brand name for clotrimazole, an antifungal used in the treatment of different types of fungal infections, such as athelete's foot (tinea pedis) and vaginal candidiasis.
Vagisil: This is the brand name for a line of feminine products that treat the itching & burning of candidiasis, not the infection itself. The product line includes a screeing kit to test for vaginal infections.Source(s): I'm a nurse.
