Elephant endotheliotropic herpesviruses (EEHV) are herpesviruses that infect elephants. They can cause a highly fatal hemorrhagic disease when transmitted to young Asian elephants . In African elephants, related forms of these viruses, which have been identified in wild populations, are generally benign, occasionally surfacing to cause small ...
Proboscivirus is located under the listings of the ICTV Updates as Section §2005.049-050V.04. [4] With the creation of Proboscivirus as a new genus came the creation and categorization of a new species under this genus, by the name of Elephantid betaherpesvirus 1 (Acronym: EEHV1 and Scientific Name: Elephant endotheliotropic herpesvirus) [5] under ICTV §2005.051-050V.04.
The virus can also target the epithelium of the mucous membranes of these organ systems. [20] Virus particles tend to exit from the lumen of the endothelium, leading to viral antigens found in the blood and lymphatic endothelial cells. However, as this virus spreads, it will be targeted to endothelial cells in lung but not in the brain, for ...
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
Viruses, however, use a completely different mechanism to cause disease. Upon entry into the host, they can do one of two things. Many times, viral pathogens enter the lytic cycle; this is when the virus inserts its DNA or RNA into the host cell, replicates, and eventually causes the cell to lyse, releasing more viruses into the environment.
The viral eukaryogenesis hypothesis posits that eukaryotes are composed of three ancestral elements: a viral component that became the modern nucleus; a prokaryotic cell (an archaeon according to the eocyte hypothesis) which donated the cytoplasm and cell membrane of modern cells; and another prokaryotic cell (here bacterium) that, by endocytosis, became the modern mitochondrion or chloroplast.
Genotyping applies to a broad range of individuals, including microorganisms. For example, viruses and bacteria can be genotyped. Genotyping in this context may help in controlling the spreading of pathogens, by tracing the origin of outbreaks. This area is often referred to as molecular epidemiology or forensic microbiology.
Plaques from a virus isolated from a compost heap near UCLA. The bacterium is M. smegmatis. A viral plaque is a visible structure formed after introducing a viral sample to a cell culture grown on some nutrient medium. The virus will replicate and spread, generating regions of cell destruction known as plaques.
