Characteristics of Candida

Candida is a brand of yeasts. Many breed are controllable commensals or endosymbionts of hosts including humans, but added species, or controllable breed in the amiss location, can could could cause disease. Candida albicans can could could cause infections (candidiasis or thrush) in bodies and added animals, abnormally in immunocompromised patients. Many breed are begin in gut flora, including C. albicans in beastly hosts, admitting others reside as endosymbionts in insect hosts.
Systemic infections of the bloodstream and above organs, decidedly in immunocompromised patients, affect over 90,000 humans a year in the U.S., with a 40-50% mortality.
The DNA of several Candida breed accept been sequenced.
Antibiotics advance aggrandize infections, including gastrointestinal Candida overgrowth, and assimilation of the GI mucosa.Many humans are beneath the consequence that alone women get animal aggrandize infections. Regardless of gender, abiding antibacterial use increases your accident of a aggrandize infection. Also, men and women with diabetes or broken allowed systems, such as those with HIV, are added affected to aggrandize infections
Characteristics
Grown in the laboratory, Candida appears as large, round, white or cream (albicans is from Latin meaning 'whitish') colonies with a yeasty odor on agar plates at room temperature. C. albicans ferments glucose and maltose to acid and gas, sucrose to acid, and does not ferment lactose, which help to distinguish it from other Candida species.
Candida are almost universal on normal adult skin and albicans is part of the normal flora of the mucous membranes of the respiratory, gastrointestinal, and female genital tracts which cause no disease.
But overgrowth of several species including albicans can cause superficial infections such as oropharyngeal candidiasis (thrush) and vulvovaginal candidiasis (vaginal candidiasis). Oral candidiasis is common in elderly denture wearers. In otherwise healthy individuals, these infections can be cured with topical or systemic antifungal medications (commonly over-the-counter treatments like miconazole or clotrimazole). In debilitated or immunocompromised patients, or if introduced intravenously, candidiasis may become a systemic disease producing abscess, thrombophlebitis, endocarditis, or infections of the eyes or other organs. Colonization of the gastrointestinal tract by C. albicans after antibiotic therapy usually causes no symptoms and may also result from taking antacids or antihyperacidity drugs.
