There is tenuous evidence that a virus common to peppers, the Pepper Mild Mottle Virus (PMMoV) may have moved on to infect humans. [9] This is a rare and unlikely event as, to enter a cell and replicate, a virus must "bind to a receptor on its surface, and a plant virus would be highly unlikely to recognize a receptor on a human cell.
Brome mosaic virus (BMV) is a small (28 nm, 86S), positive-stranded, icosahedral RNA plant virus belonging to the genus Bromovirus, family Bromoviridae, in the Alphavirus-like superfamily. BMV was first isolated in 1942 from bromegrass ( Bromus inermis ), [ 2 ] had its genomic organization determined by the 1970s, and was completely sequenced ...
In that year, the Edmonston-B strain of measles virus was turned into a vaccine by John Enders and colleagues and licensed in the United States. [ 14 ] [ 15 ] In 1968, an improved and even weaker measles vaccine was developed by Maurice Hilleman and colleagues, and began to be distributed, becoming the only measles vaccine used in the United ...
Rubella virus specific IgM antibodies are present in people recently infected by rubella virus, but these antibodies can persist for over a year, and a positive test result needs to be interpreted with caution. [25] The presence of these antibodies along with, or a short time after, the characteristic rash confirms the diagnosis. [26]
