Study Notes
Candida Albicans
- Candida albicans is the most common cause of opportunistic mycoses.
Morphology
- At 25°C, Candida albicans grows as pseudo-hyphae.
- At 37°C, Candida albicans grows as true hyphae with germ tubes.
Characteristics
- Candida albicans is catalase-positive.
- It is a normal flora of the GI tract and oral cavity, and commonly contaminates sputum cultures.
Infections
- Candida albicans can cause severe diaper rash, especially when exposed to heat and humidity.
- Oral candidiasis usually occurs in immunocompromised individuals or those using inhaled steroids.
- Candida albicans can cause esophagitis, characterized by white pseudo-membranes.
- It can also cause vaginal candidiasis, especially in diabetics, those taking antibiotics, and those using birth control pills.
- Candida infections are more likely to occur at pH levels below 4.
- Candida albicans can cause endocarditis, especially in IV drug users who are infected with contaminated heroin.
Treatment
- Azoles are used to treat minor infections.
- Amphotericin B is used to treat major infections.
- Nystatin is used to treat oral or esophageal candidiasis.
- Capsofungin is used to treat resistant Candida infections.
