Calcium-binding atopy-related autoantigen 1, a protein that in humans is encoded by the CBARA1 gene.  A calcium binding atopy-related autoantigen. 3d rendering.
Candida albicans grown on chromogenic agar plates. Candida albicans, a fungus naturally present in small quantities on the body, inhabits areas such as the mouth, skin, and intestines. When the balance with healthy bacteria is disrupted, Candida can lead to infections like thrush and vaginal yeast infections. These infections are frequent and typically addressed with antifungal medications.
