Bacterial vaginosis. Computer illustration of Gardnerella vaginalis bacteria (rods) attached to epithelial cells, known as clue cells. G. vaginalis is one of the species of bacteria that cause vaginosis. Clue cells are a diagnostic feature of bacterial vaginosis found during light microscopy of a cervical smear. Bacterial vaginosis causes an abnormal vaginal discharge with an unpleasant fishy smell. It is caused by an imbalance of the normal vaginal flora. Treatment is with antibiotics.

Avian influenza virus (H5N1) infection process. The virus enters the cell by endocytosis (top left). The endosome (yellow) moves to the cell nucleus and releases viral genetic information via disassembled nucleocapsid RNA and ribonucleoproteins (vRNP's). The host cell nucleus then directs the synthesizing of new viral components, which assemble and bud off.
Dark field photomicrograph of Volvox aureus, a colonial green alga, with gonidia (daughter colonies), mag. 35x (at 24 x 36 mm). Individual flagellated cells of this chlorophyte form a coordinated spherical colony. Larger eyespots on anterior cells enable the colony to swim towards the light. Posterior cells are specialized for asexual reproduction.
Illustration of various of biomarkers. These include mitochondrial DNA, bloodborne viral particles, single nucleotide polymorphisms (SNP's, or snips), nuclear debris from apoptotic cells, tyrosine kinase receptors, and other metabolic pathway proteins. They are used to track down cancers and identify processes vulnerable to therapeutic intervention.
Illustration of an avian influenza A virus (H5N1) virion, cutaway view. Shown from outside to center: hemagglutinin (HA) and neuraminidase (NA) glycoprotein spikes embedded in the lipid bilayer membrane envelope; matrix protein shell; and core, including the helical nucleocapsids (RNA plus NP nucleoproteins) and 3-protein polymerases (sphere triplets).
