A nude mouse. A nude mouse is a laboratory mouse from a strain with a genetic mutation that causes a deteriorated or absent thymus, resulting in an inhibited immune system due to a greatly reduced number of T cells.
Most are derived from the albino Wistar rat, which is still widely used. Other common strains are the Sprague Dawley, Fischer 344, [8] Holtzman albino strains, Long–Evans, and Lister black hooded rats. Inbred strains are also available, but are not as commonly used as inbred mice. Much of the genome of Rattus norvegicus has been sequenced. [9]
About 1,000 albino laboratory mice discovered earlier this year in a clandestine lab in Reedley were being kept in such “terrible” and “inhumane” conditions that they were apparently ...
BALB/c is an albino, laboratory-bred strain of the house mouse from which a number of common substrains are derived. Now over 200 generations from New York in 1920, BALB/c mice are distributed globally, and are among the most widely used inbred strains used in animal experimentation.
Mice are good jumpers, climbers, and swimmers, and are generally considered to be thigmotactic, i.e. usually attempt to maintain contact with vertical surfaces. [citation needed] Mice are mostly crepuscular or nocturnal; they are averse to bright lights. The average sleep time of a captive house mouse is reported to be 12.5 hours per day.
It is the most widely used "genetic background" for genetically modified mice for use as models of human disease. They are the most widely used and best-selling mouse strain due to the availability of congenic strains, easy breeding, and robustness. [1] The median lifespan of C57BL/6 mice is 27–29 months and the maximum lifespan is about 36 ...
