When it comes to discussing the furry little creatures that scurry around our homes and labs, there seems to be a bit of confusion about the proper terminology. Should we call them mice or murine? Let’s clear up the confusion once and for all.
The answer is that both words are technically correct, but they have slightly different connotations. Mouse is the more commonly used term, and it generally refers to the small, domesticated rodents that we keep as pets or use in scientific research. Murine, on the other hand, is a more formal term that refers specifically to the family of rodents that includes mice, rats, and other similar creatures.
So, to sum up: mouse means a small, domesticated rodent, while murine refers to a broader family of rodents that includes mice.
Now that we’ve cleared up the terminology, let’s dive a little deeper into the world of these fascinating creatures.
Define Mouse
A mouse is a small rodent that belongs to the family Muridae. It is also known as a house mouse, field mouse, or common mouse, and is found all over the world. The scientific name for the mouse is Mus musculus.
The mouse has a pointed snout, small rounded ears, and a long, scaly tail. It has a compact body with short legs and sharp claws, which it uses for digging and climbing. The mouse is a social animal, and it lives in groups called colonies.
Define Murine
Murine is an adjective that refers to anything related to or resembling a mouse. It is often used in scientific literature to describe experiments or studies that involve mice. For example, a murine model is a laboratory animal that is genetically engineered to mimic human diseases.
The term murine is derived from the Latin word mus, which means mouse. It is sometimes used interchangeably with the word mouse, but it is more commonly used in scientific contexts. Murine antibodies, for instance, are antibodies produced by mice that are used in research and medical applications.
How To Properly Use The Words In A Sentence
When it comes to discussing the differences between mouse and murine, it’s important to understand how to properly use these words in a sentence. Here’s a breakdown of how to use each word correctly:
How To Use “Mouse” In A Sentence

Common Mistakes To Avoid
When it comes to discussing laboratory animals, people often use the terms “mouse” and “murine” interchangeably. However, this can lead to confusion and misunderstanding, as these terms have different meanings and implications. Here are some common mistakes to avoid:
Using “Mouse” And “Murine” As Synonyms
While “mouse” refers specifically to the Mus musculus species, “murine” is a broader term that encompasses all rodents in the Muridae family, including rats and hamsters. Using “mouse” and “murine” as synonyms can be misleading and inaccurate, especially when discussing research studies or experimental protocols that involve different rodent species.
Assuming Uniformity Among Mouse Strains
Another common mistake is assuming that all mouse strains are identical and interchangeable. In reality, different mouse strains have distinct genetic backgrounds, phenotypic traits, and susceptibilities to diseases and environmental factors. Using the wrong mouse strain for a particular experiment can lead to inconsistent or invalid results, and can waste time, resources, and animal lives.
Ignoring Ethical And Welfare Considerations
Finally, a common mistake is ignoring the ethical and welfare considerations involved in using mice and other laboratory animals. Mice are sentient beings that can experience pain, distress, and suffering, and their use in research should be justified, minimized, and optimized. Researchers should follow the 3Rs principles of replacement, reduction, and refinement, and use alternative methods whenever possible.
Tips For Avoiding Common Mistakes
- Use precise and accurate terminology when referring to laboratory animals, and avoid using vague or misleading terms.
- Consult with experts in the field to select the appropriate mouse strain for your research question, and consider the genetic, phenotypic, and environmental factors that may affect your results.
- Follow the ethical and welfare guidelines and regulations that govern the use of laboratory animals, and prioritize their welfare and well-being.
Context Matters
When it comes to discussing research involving mice, the terms “mouse” and “murine” are often used interchangeably. However, the choice between these terms can actually depend on the context in which they are used.
Different Contexts
For example, in a scientific paper discussing the genetics of a specific strain of laboratory mice, it would be appropriate to use the term “murine” to refer to the species as a whole. This is because “murine” specifically refers to members of the genus Mus, which includes all species of mice.
On the other hand, in a more general discussion about the use of mice in research, the term “mouse” may be more appropriate. This is because “mouse” is a more commonly understood term, and is often used in a broader sense to refer to any member of the Mus genus that is used in research.
Additionally, the choice between “mouse” and “murine” can depend on the specific field of research being discussed. For example, in the field of immunology, the term “murine” is often used to refer specifically to mice that have been genetically modified to have a human immune system. This is because these mice are specifically designed for use in immunological research, and the term “murine” helps to differentiate them from other strains of laboratory mice.
Examples
To further illustrate the importance of context in choosing between “mouse” and “murine,” consider the following examples:
- In a paper discussing the use of mice in cancer research, the term “mouse” would likely be used throughout the paper to refer to the various strains of laboratory mice being studied.
- In a paper discussing the genetic makeup of a specific strain of laboratory mice, the term “murine” would be more appropriate to use when referring to the species as a whole.
- In a paper discussing the use of genetically modified mice in immunological research, the term “murine” would be used specifically to refer to the strains of mice that have been modified to have a human immune system.
Overall, it is important to consider the context in which the terms “mouse” and “murine” are being used in order to ensure clear and accurate communication in scientific research.
Exceptions To The Rules
While the general rule is to use “mouse” when referring to the common laboratory animal and “murine” when referring to the taxonomic family, there are some exceptions to this rule.
1. In Veterinary Medicine
In veterinary medicine, “mouse” is often used to refer to all rodents, including those in the murine family. This is because the term “murine” is not commonly used outside of scientific circles and may not be understood by pet owners or the general public.
For example, a veterinarian may say “your mouse has a respiratory infection” even if the pet in question is actually a member of the murine family such as a rat or hamster.
2. In Genetics Research
In genetics research, “mouse” is often used to refer to any genetically modified mouse, regardless of whether it is a member of the Mus family or not. This is because genetically modified mice are often created by inserting foreign DNA into the mouse genome, making them distinct from their wild-type counterparts.
For example, a researcher may say “we created a mouse model of Alzheimer’s disease” even if the mouse in question is not a member of the Mus family.
3. In Conservation Biology
In conservation biology, “mouse” is often used to refer to any small rodent that is threatened or endangered, regardless of whether it is a member of the Mus family or not. This is because many small rodent species are often lumped together under the common name “mouse” for conservation purposes.
For example, a conservation biologist may say “we need to protect the New Zealand mouse” even though the New Zealand mouse is actually a member of the genus Zyzomys and not the Mus family.
Overall, while it is important to use the correct terminology when referring to the Mus family, there are some situations where the rules for using “mouse” and “murine” may not apply.
