Factors Related to Animal Neglect in Brazilian Laboratories.

Our objectives were to identify the prevalence of negligence of laboratory animals in Brazil, to determine the primary factors associated with its occurrence and to suggest prevention strategies. A questionnaire was made available online between October 2015 and March 2016. A total of 116 respondents with experience in the use of laboratory animals and/or the use of alternative methods answered the questionnaire. Most respondents were women (77 respondents, 66.4%), a significant proportion had a degree in Veterinary Medicine (31 respondents, 27.2%), and a majority used animals in their work (88 respondents, 75.9%). Of the 88 animal users, 23 supplied information on the numbers and species of animals they used. When asked whether they knew that Brazilian law forbade animal experimentation when alternative methods exist, seven (9.1%) respondents mentioned Act 9605/1998. Most, but not all, respondents (96 respondents, 82.8%) submitted their projects to an Animal Use and Ethics Committee (AUEC), and many (65 respondents, 56%) reported their belief that animal neglect occurred at their institution. Negligence was found to be associated with: institutions where the numbers of animals used were not recorded (p = 0.008); institutions where respondents were unaware of the relevant legislation, that is, Act 9605/1998 (p = 0.042); or where there was evidence that not all project proposals were submitted to the AUEC or evidence of no submissions at all (p = 0.022). Negligence of animals was found to be highly prevalent. Prevention strategies might involve increased transparency to the general public, the empowerment of individuals that work with animals to report any concerns, optimised inspection of facilities where animal work is carried out and significant improvements to the role of AUECs.

Brazil starts to ban animal use in higher education: A positive and progressive development.

The Brazilian government has published a resolution that bans animal use in some practical classes within undergraduate and high school technical education from April 2019. Resolution No. 38/2018, issued by the National Council for the Control of Animal Experimentation (CONCEA), bans the killing of animals for dissection purposes and animal experiments in practical classes that do not involve the acquisition of new skills. The initial call for the ban was by the Brazilian Network for Humane Education (RedEH), an independent body comprising Brazilian professors and international collaborators dedicated to the implementation of replacement alternatives in education. The call was supported by InterNICHE, and many professors and other international organisations. The Brazilian Council of Veterinary Medicine, which is responsible for regulating the veterinary profession in Brazil, also stated its support for humane education and for the ban. The call was the first formal request, and it eventually led to the first legal resolution for the replacement of animal use in education in Brazil. This represents an important historic landmark in the advancement of science education.

On the journey toward humane education in Brazil: First request for a total ban of harmful animal use in professional and higher education.

The Brazilian Network for Humane Education (RedEH( is an independent and self-managed group comprised of academics from ten different Brazilian states and a number of international collaborators. In 2016, in a concerted effort to change the educational field in Brazil and propagate humane education, RedEH sent a request to the Brazilian National Council for the Control of Animal Experimentation (CONCEA(, asking that harmful animal use in education in professional and undergraduate courses be banned. This was the first formal request for a total replacement of harmful animal use in education in Brazil, and represented a major historic landmark in the advancement of Brazilian science education. This paper presents the full text of the request, as well as outlining its national and international repercussions. The request was supported by InterNICHE and representatives of 18 other international organisations. A major national impact of the request was its recognition by the Federal Council of Veterinary Medicine. With this action, academics and researchers took a potentially revolutionary step in the Brazilian education arena, with regard to advancing and supporting a higher quality, ethical and democratic educational system.

Brazilian attitudes towards the use of animals in research / Atitudes de brasileiros no uso de animais em pesquisa

Little research has examined the views of Latin Americans on the use of animals in research. This study examined the degree to which Brazilians support the use of animals in research and the reasons they put forth to explain their position. Participants were randomly assigned to research scenarios describing the use of animals for biomedical or environmental benefits, and varying in the number of pigs required. Each scenario began by proposing the use of conventional pigs and then advanced to the development and use of genetically modified animals (GMA). A total of 151 quantitative and 307 qualitative answers were analysed. Scenario and number of animals had little effect on support, but opposition increased from 25% to 58% when pigs were used to develop a GM strain for the environmental scenario. Support to use of animals was often conditional upon adequate protection of the animals' welfare. Participants were less willing to support research on environmental scenario when this involved the creation of GMA, in part because they feared the risk associated with this technology.(AU)

Há poucos estudos sobre a opinião de latino-americanos quanto ao uso de animais em pesquisa. Este estudo avaliou o grau de apoio e as motivações de brasileiros em relação a essa questão. Os participantes foram aleatoriamente apresentados a dois cenários, um biomédico e outro ambiental, variando também o número de animais usados. Cada cenário se iniciava com o uso de suínos convencionais e prosseguia com o desenvolvimento e uso de animais geneticamente modificados. Foram analisadas 151 respostas quantitativas e 307 qualitativas. O cenário e o número de animais tiveram pouco efeito no apoio ao uso dos animais, no entanto, a oposição aumentou de 25% para 58% quando o uso de suínos geneticamente modificados foram apresentados no cenário ambiental. O apoio ao uso de animais em pesquisa estava frequentemente condicionado ao grau de bem-estar animal, e o apoio à pesquisa diminuiu com o uso de animais geneticamente modificados, em parte, devido aos riscos associados a essa tecnologia.(AU)

The use of a decision tree based on the rabies diagnosis scenario, to assist the implementation of alternatives to laboratory animals.

Brazilian federal legislation makes the use of alternatives mandatory, when there are validated methods to replace the use of laboratory animals. The objective of this paper is to introduce a novel decision tree (DT)-based approach, which can be used to assist the replacement of laboratory animal procedures in Brazil. This project is based on a previous analysis of the rabies diagnosis scenario, in which we identified certain barriers that hinder replacement, such as: a) the perceived higher costs of alternative methods; b) the availability of staff qualified in these methods; c) resistance to change by laboratory staff; d) regulatory obstacles, including incompatibilities between the Federal Environmental Crimes Act and specific norms and working practices relating to the use of laboratory animals; and e) the lack of government incentives. The DT represents a highly promising means to overcome these reported barriers to the replacement of laboratory animal use in Brazil. It provides guidance to address the main obstacles, and, followed step-by-step, would lead to the implementation of validated alternative methods (VAMs), or their development when such alternatives do not exist. The DT appears suitable for application to laboratory animal use scenarios where alternative methods already exist, such as in the case of rabies diagnosis, and could contribute to increase compliance with the Three Rs principles in science and with the current legal requirements in Brazil.

Comparative costs of the Mouse Inoculation Test (MIT) and Virus Isolation in Cell Culture (VICC) for use in rabies diagnosis in Brazil.

The decision to use laboratory animals rather than in vitro methods is frequently based on the financial costs involved, so the objective of our study was to compare the costs of performing the Mouse Inoculation Test (MIT) and Virus Isolation in Cell Culture (VICC) for use in rabies diagnosis in Brazil. Based on observations of laboratory routines at the Pasteur Institute, São Paulo, we listed the fixed cost (FC) and variable cost (VC) items necessary to perform both tests. Considering that 200 MITs are equivalent to 350 VICC assays, in terms of facilities and staff-hours needed per month, we calculated, for both tests, the average total cost per sample, the costs of the implementation of the laboratory structure, and the costs of routine use. With regard to absolute values, the total cost was mainly influenced by FC items, as they represented 60% of the cost for the MIT and 86% of the cost for VICC. A sample analysed by the MIT costs around 205% more than one analysed by using VICC. The MIT costs 74% and 406% more than VICC, when implementation costs and routine use per month, respectively, are taken into account. Our results can assist in the resolution of costing disputes that could hinder the replacement of animals for rabies diagnosis in Brazil. The method demonstrated here might also be useful for cost comparisons in other situations where animal use still continues when validated alternatives exist.

Perceived barriers to the adoption of alternatives to laboratory animal use for rabies diagnosis.

The use of laboratory animals is still common practice, but some uses can be replaced by alternative methods, such as Virus Isolation in Cell Culture (VICC) instead of the Mouse Inoculation Test (MIT) for rabies diagnosis. The objective of this work was to describe current rabies diagnosis methods in Brazil and other countries, and the constraints associated with replacing this use of mice with alternative methods. Nine out of 12 Brazilian and 14 out of 43 non-Brazilian respondents reported that they currently used the MIT. Respondents in countries other than Brazil, male respondents, and those already employing in vitro methods for rabies diagnosis, expressed higher levels of support for the use of alternatives. The most frequently reported constraints associated with the use of alternatives were lack of laboratory facilities, equipment and materials (cited 17 times by respondents), and lack of financial resources (cited 15 times). The results indicate that many laboratories continue to use mice for rabies diagnosis. The proportion of laboratories that use mice appears to be especially high in Brazil, despite animal protection laws and technical guidelines that favour the use of alternatives. The barriers to the adoption of alternative methods identified in the current study provide a basis for facilitating changes in Brazil and elsewhere.
