Metavirus is a genus of viruses in the family Metaviridae. [1] They are retrotransposons that invade a eukaryotic host genome and may only replicate once the virus has infected the host. [2]
Infective conjunctivitis is most commonly caused by a virus. [3] Bacterial infections, allergies, other irritants, and dryness are also common causes. Both bacterial and viral infections are contagious, passing from person to person or spread through contaminated objects or water. Contact with contaminated fingers is a common cause of ...
Major symptoms are sudden loss of vision (partial or complete), sudden blurred or "foggy" vision, and; pain on movement of the affected eye. [4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.

In particular, owl's eye appearance has been used to indicate the presence of cytomegalovirus (CMV), a genus of virus found in humans and other primates. The description "owl's eye" may refer to: Cells with perinuclear vacuolization around centrally located pyknotic nuclei, such as typically seen in flat warts .
Dispersion-shifted fiber (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation.. Dispersion Shifted Fiber is a type of single-mode optical fiber with a core-clad index profile tailored to shift the zero-dispersion wavelength from the natural 1300 nm in silica-glass fibers to the minimum-loss window at 1550 nm.
Watermelon mosaic virus (WMV) also known as Marrow mosaic virus (Raychaudhuri and Varma, 1975; Varma, 1988), Melon mosaic virus (Iwaki et al., 1984; Komuro, 1962), and until recently Watermelon mosaic virus type 2 (WMV-2), [1] is a plant pathogenic virus [2] that causes viral infection (sometimes referred to as watermelon Mosaic disease) in many different plants.
