The final "r" sounds like a soft "uh" sound, represented by the "ə" symbol. Overall, the word is pronounced as "Wih-stuh-r."
Wistar is a proper noun that refers to a well-known and widely used strain of laboratory rats called Wistar rats.
The Wistar rats are a specific breed of albino laboratory rats that were first developed at the Wistar Institute in Philadelphia, Pennsylvania, in the early 1900s. These rats are characterized by their white fur and pink eyes, which are considered important features for ease of observation and identification in research studies.
The Wistar rats have become the standard model for biological and medical research due to their high fertility, adaptability, and relatively docile nature. They are used extensively in various scientific fields, including toxicology, cancer research, genetics, and behavioral studies. Scientists rely on them to investigate the effects of drugs, chemicals, diseases, and other experimental conditions, as they mimic human responses to a certain extent.
Due to their consistent genetic background and uniformity, Wistar rats are highly suitable for conducting experiments that require reproducibility and accurate comparisons between different research groups. Their prevalence in scientific research has led to the establishment of numerous strains and sub-strains derived from the original Wistar rats.
In summary, Wistar refers to a breed of laboratory rats that are widely utilized in scientific research due to their desirable characteristics and genetic consistency, making them an essential tool in experimental studies across various disciplines.
The word "Wistar" has its etymology rooted in the German origin. It derives from the German surname "Wüster", which means "desolate" or "uninhabited". The surname "Wüster" underwent anglicization when Caspar Wistar, an 18th-century German-born American physician, changed the spelling of his name to "Casper Wistar" after migrating to the United States. This modified spelling eventually became associated with his prominent descendants, including Caspar Wistar's grandson, Dr. Caspar Wistar Jr., who further contributed to the usage of the name. As a result, the name "Wistar" has been widely recognized and associated with various people, places, and institutions related to the Wistar family.
