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 is found to cause tumors in humans and animals, but most often persists as a dormant infection. SV40 has been widely studied as a model eukaryotic virus, leading to many early discoveries in eukaryotic DNA replication and transcription. ==Human disease== The hypothesis that SV40 might cause cancer in humans was a particularly controversial area of research, fuelled by the historical contamination of some batches

Tetrahymena is a genus of free-living ciliates, examples of unicellular eukaryotes. The genus Tetrahymena is the most widely studied member of its phylum. It can produce, store and react with different types of hormones. Tetrahymena cells can recognize both related and hostile cells.

Cepaea is a genus of large air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Helicidae. The shells are often brightly coloured and patterned with brown stripes. The two living species in this genus, C. nemoralis and C. hortensis, are widespread and common in Western and Central Europe. In North America, C. hortensis is native on the northeast coast, but both species have been introduced elsewhere, and they are also spreading further east in Europe. Both have been influential model species for ongoing studies of genetics and natural selection. Like many Helicidae

Gnotobiosis (from Greek roots gnostos "known" and bios "life") refers to an engineered state of an organism in which all forms of life (i.e., microorganisms) in or on it, including its microbiota, have been identified. The term gnotobiotic organism, or gnotobiote, can refer to a model organism that is colonized with a specific community of known microorganisms (isobiotic or defined flora animal) or that contains no microorganisms (germ-free) often for experimental purposes. The study of gnotobiosis and the generation of various types of gnotobiotic model organisms as tools for studying interac
