laboratory mice are forms of house mice that are used for scientific use to find out about all sorts of things such as allergies, cancer drugs and many other drugs are tested on mice long before humans get any sort of look in . The mouse originally came from south western Asia, humans have helped with the spread of mice. Mice will live any where within a building during the winter but usually venture outside during the summer. They can also flatten themselves to enable themselves to get under doors. They aren’t fussy eaters either there favourite food is usually cereal but if they get very desperate they will eat soap from the bathroom which is connected with GENOMICS. They often cause a lot of damage and can gnaw there way through wires, wood, carpets almost anything. However they don’t tend to eat much they eat about 3 grams a day which is not a lot. They don’t drink a lot because they take all there moisture from food. They poo about 80 droppings a day which is a lot for a mouse. The lady mouse has a pregnancy gestation period of 3 weeks which is a has a known connection with HEALTH. There litter can vary between 4 to 16 it all depends on how much food they have in their stomach. They can be pregnant 7 to 8 times a year so that is 7 or 8 litters that there are a lot of little mice running around. Around 8 to 12 weeks is when the mice reach sexual maturity then they can too have litters of their own. The mortality rate is around 90%. These mice usually carry diseases these being Salmonella, Hantavirus and Lyme disease. laboratory mice are just different strains of house mice, the most commonly used for laboratory experiments is Mus Musculus domesticus and Mus musculus musculus. They all come with different coloured coats including black and albino. Numerous amounts of laboratory strains of mice are inbred this is to make them genetically identical. The patterns of behavior in laboratory mice are very different from those of the common house mice this is due to years spent in laboratory testing facilities. There are many benefits to using mice for laboratory research as mice are small they are inexpensive, can reproduce quickly and are easy to maintain. It only takes a short period of time to observe several generations of mice. Mice can become docile if they are raised by humans from birth. Certain strains of mice have been known to become quite temperamental. Clarence Cook Little in 1909 were the first inbred strains that were produced. Little was influential in encouraging the use of mice as a laboratory organism. In 2002 sequencing of the mouse genome was completed. Mice in a laboratory can also be manipulated in ways that would be considered immoral in humans. There are minimal standards that have to be adhered to when keeping mice in a laboratory .
