Colby, L. A., Nowland, M. H., Kennedy, L. H. 2019. Clinical Laboratory Animal Medicine: An Introduction (5th Ed). Wiley-Blackwell, Ames, IA.

The revised fifth edition of Clinical Laboratory Animal Medicine: An Introduction is an accessible guide to basic information for conducting animal research safely and responsibly. It includes a review of the unique anatomic and physiologic...

Young, T., Whiteside, T., Locklear, J. 2020. What is your tattoo ink telling you? Laboratory Animal Science Professional 8(2) (March/April), 62-65.

Tattooing traumatizes the skin, which can result in microbial infections with the severity ranging from minor to life-threating septicemia. Additionally, the metals in colored tattoo ink are known to cause dermal inflammation in some people...

Jirkof, P., Bratcher, N., Medina, L. et al. 2020. The effect of group size, age and handling frequency on inter-male aggression in CD 1 mice. Scientific Reports 10(1), 2253.

Aggression in male mice often leads to injury and death, making social housing difficult. We tested whether (1) small group size, (2) early age of allocation to a group decreases aggression and 3) manipulation increases...

Ueno, H., Takahashi, Y., Suemitsu, S. et al. 2020. Effects of repetitive gentle handling of male C57BL/6NCrl mice on comparative behavioural test results. Scientific Reports 10(1), 3509.

Mice are the most commonly used laboratory animals for studying diseases, behaviour, and pharmacology. Behavioural experiment battery aids in evaluating abnormal behaviour in mice. During behavioural experiments, mice frequently experience human contact. However, the effects...

Henderson, L. J., Smulders, T. V., Roughan, J. V. 2020. Identifying obstacles preventing the uptake of tunnel handling methods for laboratory mice: An international thematic survey. PLOS ONE 15(4), e0231454.

Handling of laboratory mice is essential for experiments and husbandry, but handling can increase anxiety in mice, compromising their welfare and potentially reducing replicability between studies. The use of non-aversive handling (e.g., tunnel handling or...

Andresen, N., Wöllhaf, M., Hohlbaum, K. et al. 2020. Towards a fully automated surveillance of well-being status in laboratory mice using deep learning: Starting with facial expression analysis. PLOS ONE 15(4), e0228059.

Assessing the well-being of an animal is hindered by the limitations of efficient communication between humans and animals. Instead of direct communication, a variety of parameters are employed to evaluate the well-being of an animal...

Chartier, L. C., Hebart, M. L., Howarth, G. S. et al. 2020. Affective state determination in a mouse model of colitis-associated colorectal cancer. PLOS ONE 15(1), e0228413.

Behavioural indicators of affective state, including burrowing, clinical scores and the Mouse Grimace Score have not yet been validated in mouse models of chronic gastrointestinal disease. Additionally, a comparison of these methods has not been...

Lewejohann, L., Schwabe, K., Häger, C. et al. 2020. Impulse for animal welfare outside the experiment. Laboratory Animals 54(2), 150–158.

Animal welfare is a growing societal concern and the well-being of animals used for experimental purposes is under particular scrutiny. The vast majority of laboratory animals are mice living in small cages that do not...

Ernst, L., Kopaczka, M., Schulz, M. et al. 2020. Semi-automated generation of pictures for the Mouse Grimace Scale: A multi-laboratory analysis (Part 2). Laboratory Animals 54(1), 92–98.

The Mouse Grimace Scale (MGS) is an established method for estimating pain in mice during animal studies. Recently, an improved and standardized MGS set-up and an algorithm for automated and blinded output of images for...

Ernst, L., Kopaczka, M., Schulz, M. et al. 2020. Improvement of the Mouse Grimace Scale set-up for implementing a semi-automated Mouse Grimace Scale scoring (Part 1). Laboratory Animals 54(1), 83–91.

The Mouse Grimace Scale (MGS) has been widely used for the noninvasive examination of distress/pain in mice. The aim of this study was to further improve its performance to generate repeatable, faster, blinded and reliable...
