Infectious bursal disease (IBD), also known as Gumboro disease, infectious bursitis, and infectious avian nephrosis, is a highly contagious disease of young chickens and turkeys caused by infectious bursal disease virus (IBDV), [1] characterized by immunosuppression and mortality generally at 3 to 6 weeks of age.
Tobacco ringspot virus (TRSV) is a plant pathogenic virus in the plant virus family Secoviridae. It is the type species of the genus Nepovirus. Nepoviruses are transmitted between plants by nematodes, thrips, mites, grasshoppers, and flea beetles. [1] TRSV is also easily transmitted by sap inoculation and transmission in seeds has been reported ...
Aerosols of concentrated virus may result in Orthopoxvirus infection, especially in unimmunized individuals. [13] In addition, needle sticks with concentrated virus or scratches from infected animals may result in local infection of the skin even in immunized individuals. Cowpox infection in Europe is an occupational hazard for veterinary ...
The virus is transmitted by mosquitoes (Culex and Culiseta). SINV is linked to Pogosta disease [3] , Ockelbo disease and Karelian fever . In humans, the symptoms include arthralgia, rash and malaise. Sindbis virus is widely and continuously found in insects and vertebrates in Eurasia, Africa, and Oceania.
Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important variable that must be monitored.
Lastly, the "env" domain of the viral genome encodes for the glycoproteins and envelope on the surface of the virus. [1] There are multiple steps involved in the infection and replication of a lentivirus in a host cell. In the first step the virus uses its surface glycoproteins for attachment to the outer surface of a cell.
The measles virus (MV), with scientific name Morbillivirus hominis, is a single-stranded, negative-sense, enveloped, non-segmented RNA virus of the genus Morbillivirus within the family Paramyxoviridae. It is the cause of measles. Humans are the natural hosts of the virus; no animal reservoirs are known to exist.
Triplex DNA structure. The arrows are going from the 5' end to the 3' end. (Triple-stranded DNA (also known as H-DNA or Triplex-DNA) is a DNA structure in which three oligonucleotides wind around each other and form a triple helix.
