Yeast Infection; Budding yeast and pseudohyphae of Candida albicans, gram's stain. This fungus commonly affects vagina and vulva, oral (thrush) and diaper rash.
Micrograph of amoeba.  Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live animal, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
A conceptual image of an abstract network of multi-coloured organic strands arranged in a non regular pattern all connected together in a complex manner. The network is made from smaller multi-coloured squares and polyhedra, in vivid colours against a pastel toned background. Shows background and foreground elements to the structure.

The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
