Sometimes articles refer to candida meaning the candidiasis or a yeast infection or candida overgrowth. Technically though Candida is the name for a group of fungi. There are many species within this genus of fungi, but most are not pathogenic. Pathogenic means they can attack their host and cause health problems. The most well known and common cause of yeast infections is Candida albicans but there are other species of candida that are the cause of infections including Candida glabrata, Candida tropicalis, Candida parapsilosis and Candida dubliniensis to name a few.
Candida lives as a benign yeast in the gut flora of animals and humans and is kept in small numbers by the good bacteria there. An overgrowth of the yeast causes it to turn into its pathogenic fungal state that attacks, releases toxins and causes yeast infections and a whole host of symptoms.
