THE POWER of LABORATORY MICE Since the First Published Study Using Mice in 1844, Over 1.4 Million Scholarly Articles Have Been Published THE POWER OF LABORATORY MICE Since the first published study using mice in 1844, over 1.4 million scholarly articles have been published. Over half of those articles have been published in the past 2 decades and twice as many were published in the decade 2007—2016 than 1997—2006. These data demonstrate the increasing value of laboratory mice in biomedical research. Genetically engineered mice bolstered this growth by improving the ability to translate results to humans. Looking forward, the laboratory mouse will continue to play a critical role in biomedical research, as the ability to generate increasingly precise models will give the researcher of tomorrow an animal that has power to further our understanding of complex human biology.

Perlman* Department of Pediatrics, The University of Chicago, 5841 S. Maryland Ave, MC 5058, Chicago, IL 60637, USA *E-mail: [email protected] Received 31 December 2015; revised version accepted 12 April 2016 ABSTRACT The use of mice as model organisms to study human biology is predicated on the genetic and physio- logical similarities between the species. Nonetheless, mice and humans have evolved in and become adapted to different environments and so, despite their phylogenetic relatedness, they have become very different organisms. Mice often respond to experimental interventions in ways that differ strikingly from humans. Mice are invaluable for studying biological processes that have been conserved during the evolution of the rodent and primate lineages and for investigating the developmental mechanisms by which the conserved mammalian genome gives rise to a variety of different species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species. The use of mice in biomedical research needs to take account of the evolved differences as well as the similarities between mice and humans.

    animals Review Enrichment for Laboratory Zebrafish—A Review of the Evidence and the Challenges Chloe H. Stevens *, Barney T. Reed and Penny Hawkins Animals in Science Department, RSPCA, Wilberforce Way, Southwater, West Sussex RH13 9RS, UK; [email protected] (B.T.R.); [email protected] (P.H.) * Correspondence: [email protected] Simple Summary: The zebrafish is one of the most commonly used animals in scientific research, but there remains a lack of consensus over good practice for zebrafish housing and care. One such area which lacks agreement is whether laboratory zebrafish should be provided with environmental enrichment—additions or modifications to the basic laboratory environment which aim to improve welfare, such as plastic plants in tanks. The need for the provision of appropriate environmental enrichment has been recognised in other laboratory animal species, but some scientists and animal care staff are hesitant to provide enrichment for zebrafish, arguing that there is little or no evidence that enrichment can benefit zebrafish welfare. This review aims to summarise the current literature on the effects of enrichment on zebrafish physiology, behaviour and welfare, and identifies some forms of enrichment which are likely to benefit zebrafish. It also considers the possible challenges that might be associated with introducing more enrichment, and how these might be addressed. Abstract: Good practice for the housing and care of laboratory zebrafish Danio rerio is an increasingly discussed topic, with focus on appropriate water quality parameters, stocking densities, feeding Citation: Stevens, C.H.; Reed, B.T.; regimes, anaesthesia and analgesia practices, methods of humane killing, and more.

  • The Pathogenesis of Spontaneous Autoimmune Peripheral Polyneuropathy: the Nod.B7-2-/- Mouse As a Model for Guillain Barré Syndrome
    THE PATHOGENESIS OF SPONTANEOUS AUTOIMMUNE PERIPHERAL POLYNEUROPATHY: THE NOD.B7-2-/- MOUSE AS A MODEL FOR GUILLAIN BARRÉ SYNDROME By Barbie J. Gadsden A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Comparative Medicine and Integrative Biology—Doctor of Philosophy 2016 ABSTRACT THE PATHOGENESIS OF SPONTANEOUS AUTOIMMUNE PERIPHERAL POLYNEUROPATHY: THE NOD.B7-2-/- MOUSE AS A MODEL FOR GUILLAIN BARRÉ SYNDROME By Barbie J. Gadsden Guillain Barré Syndrome (GBS) is a symmetrical ascending paralysis that often follows viral or bacterial infection. The foodborne pathogen Campylobacter jejuni is the most common infection that triggers GBS, but C. jejuni is mainly linked to one variant within a complex syndrome: Acute Motor Axonal Neuropathy (AMAN). One third of AMAN patients have IgG autoantibodies against neurogangliosides GM1 and GD1a; binding of these antibodies to peripheral nerves is thought to initiate nerve damage. Other GBS variants include Acute Inflammatory Demyelinating Polyneuropathy (AIDP), Acute Motor and Sensory Axonal Neuropathy (AMSAN), and Miller Fisher Syndrome (MFS). The triggers for these disorders are not known and a large number of potential infectious and noninfectious initiating causes have been implicated. In addition to C. jejuni, bacteria such as Mycoplasma pneumonia and Haemophilus influenzae and viruses such as Cytomegalovirus and Influenza have been associated with GBS. GBS disease is monophasic; recurrence is rare, but has been reported. Patients in the initial stages of GBS report headache and joint pain. Tingling and numbness of extremities is followed by segmental ascending paralysis. Pain involving the extremities occurs later in the course of the disease and can be directly correlated with disease severity.

I Behavioural Ecology of New Zealand Invasive Rodents (Rattus norvegicus and Mus musculus): Implications for Rodent Control A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Ecology at Massey University, Auckland, New Zealand Idan Shapira 2013 II FRONTISPIECE Walter: And let's also not forget… let's not forget, Dude… that keeping wildlife, an amphibious rodent, for uh, domestic, you know, within the city… that isn't legal either. Dude: What're you, a fucking park ranger now? (Ethan and Joel Coen, “The Big Lebowski”) III ABSTRACT Biological invasions are natural phenomena that have occurred throughout the natural history of earth. The highly negative context of the term biological invasion is associated with the fact that many modern invasive processes are anthropogenically driven. Indeed, human affiliated invasions are among the primary drivers of the current biodiversity crises. Murid rodents (Rodentia: Muridea) of the genus Rattus and Mus have become among the worst vertebrate invasive species and apart from man are the most widespread mammals on earth. Invasive rodents have severe and negative effects on human health, agricultural systems, and natural environments. The practice of rodent control is extensive and substantial attempts are made to decrease rodents’ severe impacts on the environment. However, although these attempts are largely successful, there are still issues in the control of invasive rodents and new methodologies, whether at a macro or micro scale are actively pursued.

  • EU Directive 2010/63/EU on Protection
    Caring for animals aiming for better science DIRECTIVE 2010/63/EU ON PROTECTION OF ANIMALS USED FOR SCIENTIFIC PURPOSES © Novo Nordisk © Novo Environment 1 The publication of "The Principles of Humane Experimental Technique" by W.M.S. Russell and R.L. Burch in 1959 marks the birth of the principles of the “Three Rs”. The authors proposed the principles of Replacement, Reduction and Refinement (the “Three Rs”) as the key strategies aimed at achieving the goal of humane experimental techniques. Russell and Burch saw replacement as the ultimate goal for laboratory animal based research, education and testing, with the other two, reduction and refinement, being more readily achievable in the short term. They summed up their main message as follows: "If we are to use a criterion for choosing experiments to perform, the criterion of humanity is the best we could possibly invent. The greatest scientific achievements have always been the most humane and the most aesthetically attractive, conveying that sense of beauty and elegance which is the essence of science at its most successful." The “Three Rs” in EU legislative framework Directive 2010/63/EU on the protection of animals used for scientific purposes, for the first time in EU legislation spells out the principle of the “Three Rs” and makes it a firm legal requirement in all aspects of care and use of animals in the field. Furthermore, the Directive ensures that its application goes beyond that of the original interpretation also to cover animal breeding and care – that is, to ensure refinement during housing, breeding and care even if the animal is not undergoing a scientific procedure.

Mendl 1 1 Bristol Veterinary School, Bristol University, Langford House, Langford BS40 5DU, UK; [email protected] 2 Research Animals Department, RSPCA, Wilberforce Way, Southwater, West Sussex RH13 9RS, UK * Correspondence: [email protected] (S.K.); [email protected] (P.H.); Tel.: +44-1403-793-231 (P.H.) Received: 17 October 2017; Accepted: 20 November 2017; Published: 24 November 2017 Simple Summary: Wild mice live in territories inhabited by one adult male, several females, and their offspring. This cannot be replicated in the laboratory, so male mice are usually housed in single-sex groups or individually. However, there can be serious animal welfare problems associated with both these approaches, such as lack of social contact when housed individually or aggression between males when kept in groups. Group housing is widely recommended to give male laboratory mice the opportunity to behave as ‘social animals’, but social stress can be detrimental to the welfare of these animals, even without injurious fighting. All of this can also affect the quality of the science, giving rise to ethical concerns. This review discusses whether it is in the best welfare interests of male mice to be housed in groups, or alone. We conclude that it is not possible to give general recommendations for good practice for housing male laboratory mice, as responses to single- and group-housing can be highly context-dependent. The welfare implications of housing protocols should be researched and considered in each case.
