SV40 is an abbreviation for simian vacuolating virus 40 or simian virus 40, a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that sometimes causes tumors in animals, but most often persists as a latent infection.
9 Ιουλ 2007 · Simian virus 40 (SV40) is a monkey virus that was administered to human populations by contaminated vaccines which were produced in SV40 naturally infected monkey cells. Recent molecular biology and epidemiological studies suggest that SV40 may be contagiously transmitted in humans by horizontal infection, independently from the earlier ...
20 Ιαν 1999 · Natural infections in monkeys by SV40 are usually benign but may become pathogenic in immunocompromised animals, and multiple tissues can be infected. SV40 can replicate in certain types of simian and human cells.
Natural exposure to SV40 in humans is considered a rare event, and antibodies to SV40 can be demonstrated only in people who have been in contact with monkeys (Shah, 1966; Engels et al., 2004a) or who had received, in the past, SV40-contaminated poliovirus vaccine.
The polyomavirus simian virus 40 (SV40) is a known oncogenic DNA virus which induces primary brain and bone cancers, malignant mesothelioma, and lymphomas in laboratory animals. Persuasive evidence now indicates that SV40 is causing infections in humans today and represents an emerging pathogen.
1 Μαρ 2022 · The extensive poliovirus vaccination programs of the late 1950s and early 1960s lead to the accidental infection of millions of individuals with an unknown virus (SV40) possessing cancer-causing potential. This mistake sparked a massive research enterprise to...
While the human polyomaviruses BKV and JCV are ubiquitous in humans, SV40 is a simian virus which was introduced in the human population, between 1955 and 1963, by contaminated poliovaccines produced in SV40- infected monkey cells.
