Fortrea primate-testing lab, Vienna, Virginia, 2004–05. Most of the NHPs used are one of three species of macaques, accounting for 79% of all primates used in research in the UK, and 63% of all federally funded research grants for projects using primates in the U.S. [25] Lesser numbers of marmosets, tamarins, spider monkeys, owl monkeys, vervet monkeys, squirrel monkeys, and baboons are used ...
Transgenic animal production consists of injecting each construct into 300–350 eggs, typically representing three days' work. Twenty to fifty mice will normally be born from this number of injected eggs. These animals are screened for the presence of the transgene by a polymerase chain reaction genotyping assay. The number of transgenic ...
However, the lack of an adaptive immune system and the simplicity of its organs prevent C. elegans from being used in medical research such as vaccine development. [3] The fly D. melanogaster is the most widely used animal in genetic studies. This comes from the simplicity of breeding and housing the flies, which allows large numbers to be used ...
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
For instance, behavioral analogues of anxiety or pain in laboratory animals can be used to screen and test new drugs for the treatment of these conditions in humans. A 2000 study found that animal models concorded (coincided on true positives and false negatives) with human toxicity in 71% of cases, with 63% for nonrodents alone and 43% for ...
An animal model (short for animal disease model) is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal model does not ensure an effect in humans ...
In 2010, a new EU directive was published on the protection of animals used for scientific purposes, repealing the old directive 86/609/EEC on January 1, 2013, with the exception of Article 13 (statistical information on the use of animals in experiments) which has been repealed on May 10, 2013.

Experiments on vertebrate animals in the European Union are since January 1, 2013. [1] [2] subject to Directive 2010/63/EU on the protection of animals used for scientific purposes, which was finalized in November 2010 and updated and replaced the Directive 86/609/EEC on the protection of Animals used for Experimental and other scientific purposes, adopted in 1986.
