Animal testing

Animal testing , also known as animal experimentation , animal research and in vivo testing , is the use of non-human animals 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 their natural environments or habitats.

Experimental research with animals is usually conducted in universities, medical schools, pharmaceutical companies, defense establishments and commercial facilities that provide animal-testing services to industry. Examples of applied research include testing disease treatments, breeding, defense research and toxicology , including cosmetics testing. In education, animal testing is sometimes a component of biology or psychology courses.

The practice is regulated to varying degrees in different countries. It is estimated that the annual use of vertebrate animals—from zebrafish to non-human primates —ranges from tens to more than million. By one estimate the number of mice and rats used in the United States alone in was 80 million. Most animals are euthanized after being used in an experiment. The terms animal testing, animal experimentation, animal research , in vivo testing, and vivisection have similar denotations but different connotations.

Literally, "vivisection" means "live sectioning" of an animal, and historically referred only to experiments that involved the dissection of live animals. The earliest references to animal testing are found in the writings of the Greeks in the 2nd and 4th centuries BC.

Aristotle and Erasistratus were among the first to perform experiments on living animals. Animals have repeatedly been used through the history of biomedical research. In , the founders of the Dublin Zoo were members of the medical profession who were interested in studying animals while they were alive and when they were dead. In the s, Ivan Pavlov famously used dogs to describe classical conditioning.

Between and , the Germans infected mules in Argentina bound for American forces, resulting in the death of mules. In the s, antibiotic treatments and vaccines for leprosy were developed using armadillos, [31] then given to humans. Toxicology testing became important in the 20th century. In the 19th century, laws regulating drugs were more relaxed. For example, in the US, the government could only ban a drug after a company had been prosecuted for selling products that harmed customers.

However, in response to the Elixir Sulfanilamide disaster of in which the eponymous drug killed more than users, the US Congress passed laws that required safety testing of drugs on animals before they could be marketed. Other countries enacted similar legislation. As the experimentation on animals increased, especially the practice of vivisection, so did criticism and controversy. In , the advocate of Galenic physiology Edmund O'Meara said that "the miserable torture of vivisection places the body in an unnatural state".

There were also objections on an ethical basis, contending that the benefit to humans did not justify the harm to animals. On the other side of the debate, those in favor of animal testing held that experiments on animals were necessary to advance medical and biological knowledge. In , the physiologist and physician Dr. Walter B. Cannon said "The antivivisectionists are the second of the two types Theodore Roosevelt described when he said, 'Common sense without conscience may lead to crime, but conscience without common sense may lead to folly, which is the handmaiden of crime.

In , the first animal protection law was enacted in the British parliament, followed by the Cruelty to Animals Act , the first law specifically aimed at regulating animal testing.

The legislation was promoted by Charles Darwin , who wrote to Ray Lankester in March "You ask about my opinion on vivisection. I quite agree that it is justifiable for real investigations on physiology; but not for mere damnable and detestable curiosity.

It is a subject which makes me sick with horror, so I will not say another word about it, else I shall not sleep to-night. Antivivisectionists of the era generally believed the spread of mercy was the great cause of civilization, and vivisection was cruel. However, in the USA the antivivisectionists' efforts were defeated in every legislature, overwhelmed by the superior organization and influence of the medical community.

Overall, this movement had little legislative success until the passing of the Laboratory Animal Welfare Act, in The regulations that apply to animals in laboratories vary across species. In the U. In general, researchers are required to consult with the institution's veterinarian and its Institutional Animal Care and Use Committee IACUC , which every research facility is obliged to maintain.

The CDC conducts infectious disease research on nonhuman primates, rabbits, mice, and other animals, while FDA requirements cover use of animals in pharmaceutical research. According to the U. The OIG found that "as a result, animals are not always receiving basic humane care and treatment and, in some cases, pain and distress are not minimized during and after experimental procedures". According to the report, within a three-year period, nearly half of all American laboratories with regulated species were cited for AWA violations relating to improper IACUC oversight.

Larry Carbone, a laboratory animal veterinarian, writes that, in his experience, IACUCs take their work very seriously regardless of the species involved, though the use of non-human primates always raises what he calls a "red flag of special concern". Funded by the National Science Foundation, the three-year study found that animal-use committees that do not know the specifics of the university and personnel do not make the same approval decisions as those made by animal-use committees that do know the university and personnel.

Specifically, blinded committees more often ask for more information rather than approving studies. Scientists in India are protesting a recent guideline issued by the University Grants Commission to ban the use of live animals in universities and laboratories. Accurate global figures for animal testing are difficult to obtain; it has been estimated that million vertebrates are experimented on around the world every year, [62] 10—11 million of them in the EU.

None of the figures include invertebrates such as shrimp and fruit flies. By comparing with EU data, where all vertebrate species are counted, Speaking of Research estimated that around 12 million vertebrates were used in research in the US in Researchers found this increase is largely the result of an increased reliance on genetically modified mice in animal studies. In , researchers at Tufts University Center for Animals and Public Policy estimated that 14—21 million animals were used in American laboratories in , a reduction from a high of 50 million used in Congress Office of Technology Assessment reported that estimates of the animals used in the U.

The use of dogs and cats in research in the U. In GB, Home Office figures show that 3. A "procedure" refers here to an experiment that might last minutes, several months, or years. Most animals are used in only one procedure: animals are frequently euthanized after the experiment; however death is the endpoint of some procedures.

A 'severe' procedure would be, for instance, any test where death is the end-point or fatalities are expected, whereas a 'mild' procedure would be something like a blood test or an MRI scan. The Three Rs 3Rs are guiding principles for more ethical use of animals in testing.

These were first described by W. Russell and R. Burch in The 3Rs have a broader scope than simply encouraging alternatives to animal testing, but aim to improve animal welfare and scientific quality where the use of animals can not be avoided.

These 3Rs are now implemented in many testing establishments worldwide and have been adopted by various pieces of legislation and regulations.

Despite the widespread acceptance of the 3Rs, many countries—including Canada, Australia, Israel, South Korea, and Germany—have reported rising experimental use of animals in recent years with increased use of mice and, in some cases, fish while reporting declines in the use of cats, dogs, primates, rabbits, guinea pigs, and hamsters.

Along with other countries, China has also escalated its use of GM animals, resulting in an increase in overall animal use. Although many more invertebrates than vertebrates are used in animal testing, these studies are largely unregulated by law. The most frequently used invertebrate species are Drosophila melanogaster , a fruit fly, and Caenorhabditis elegans , a nematode worm. In the case of C. However, the lack of an adaptive immune system and their simple organs prevent worms from being used in several aspects of medical research such as vaccine development.

Several invertebrate systems are considered acceptable alternatives to vertebrates in early-stage discovery screens. Drosophila melanogaster and the Galleria mellonella waxworm have been particularly important for analysis of virulence traits of mammalian pathogens. Mice are the most commonly used vertebrate species because of their size, low cost, ease of handling, and fast reproduction rate. Over , fish and 9, amphibians were used in the UK in Over 20, rabbits were used for animal testing in the UK in The numbers of rabbits used for this purpose has fallen substantially over the past two decades.

In , there were 3, procedures on rabbits for eye irritation in the UK, [96] and in this number was just Cats are most commonly used in neurological research. In the UK, just procedures were carried out on cats in The number has been around for most of the last decade. Dogs are widely used in biomedical research, testing, and education—particularly beagles , because they are gentle and easy to handle, and to allow for comparisons with historical data from beagles a Reduction technique.

They are used as models for human and veterinary diseases in cardiology, endocrinology , and bone and joint studies, research that tends to be highly invasive, according to the Humane Society of the United States. One of the most significant advancements in medical science involves the use of dogs in developing the answers to insulin production in the body for diabetics and the role of the pancreas in this process. They found that the pancreas was responsible for producing insulin in the body and that removal of the pancreas, resulted in the development of diabetes in the dog.

After re-injecting the pancreatic extract, insulin , the blood glucose levels were significantly lowered. The U. Non-human primates NHPs are used in toxicology tests, studies of AIDS and hepatitis, studies of neurology , behavior and cognition, reproduction, genetics , and xenotransplantation. They are caught in the wild or purpose-bred.

In the United States and China, most primates are domestically purpose-bred, whereas in Europe the majority are imported purpose-bred.

Department of Agriculture , there were 71, monkeys in U. As of [update] , there are approximately chimpanzees in U. The first transgenic primate was produced in , with the development of a method that could introduce new genes into a rhesus macaque.

Animals used by laboratories are largely supplied by specialist dealers. Sources differ for vertebrate and invertebrate animals. Most laboratories breed and raise flies and worms themselves, using strains and mutants supplied from a few main stock centers.

Animal shelters also supply the laboratories directly. Department of Agriculture USDA to sell animals for research purposes, while Class B dealers are licensed to buy animals from "random sources" such as auctions, pound seizure, and newspaper ads. Some Class B dealers have been accused of kidnapping pets and illegally trapping strays, a practice known as bunching.
