There are over 40 different species of Candida (often misspelled Candita), however, only a handful are harmful to us. This page  outlines the types that interact with humans and provides a brief description of each.

Candida albicans

This species is  the most common species in our bodies. It lives in our digestive tract and on our skin. Normally it lives in our bodies in a commensal relationship with us meaning we both benefit from each other. However, C. ablicans overgrowth can occur which results in infection most commonly in the genital area and the mouth.

Candida dubliniensis

This species also is found everywhere in our surroundings and is very similar to C. albicans, however, it usually only causes infection in those with AIDS and others who have compromised immune systems. Infections in the mouth area usually result.

Candida glabrata

This once thought to be harmless species is now causing infections in those with compromised immune systems such as those with AIDS. It usually infects the urogenital tract and the blood stream. The mortality rate is high with this species.

Candida krusei

This species is used in the chocolate making process and is usually harmless to humans. However, in those with compromised immune systems and those with types of blood cancer and can cause dangerous infections.

Candida lusitaniae

This species was first identified to cause infection in 1979 but very few cases were reported until recently with wide use of procedures such as chemotherapy and bone marrow transplants which leaves humans open to infection by this species.

Candida milleri

This is a harmless species used along with bacteria to make sourdough bread.

Candida parapsilosis

This is another species that is common to our bodies and it is the most common species found on our hands. However, it can infect open wounds and surgical patients.
