Archival Research on Bacterial Infections, Part 2: Responses to TB in Dick Vet, RZSS and OneKind Archival Records

Now for the next part in this series on bacterial infections, sharing some findings from archival research!

The Dick Vet, RZSS and OneKind, or SSPV (Scottish Society for the Prevention of Vivisection), each related animal health and welfare to human health, but in somewhat different ways. All three organisations acknowledged the conditions that could lead to zoonotic disease transmission and outbreaks of disease such as TB; they noted poor welfare conditions reducing animals’ resistance, and poor health in the case of humans (diet, etc), along with crowded and unhygienic conditions. But they presented different perspectives in the early to mid-twentieth century on how to tackle public health issues of bacterial infections, based on different understandings of animal welfare and cruelty.

The Dick Vet attended to animal health often in the service of human health, especially in the case of animals in agriculture, their main practice in the mid 19th to early 20th centuries prior to the burgeoning of companion animal ownership. The Dick Vet contributed to the Scottish Branch of the National Veterinary Medicine Association (NVMA) and its scheme for the Eradication of Bovine TB, which recognised that stress in cows reduced resistance to disease:  

‘It may also be said that the body economy of the individual cows moved from market to market soon after calving is often so upset that resistance to new infection or infection already established is greatly reduced. The spread of the disease is encouraged in this way’.  (Scottish Branch of NVMA 1933)

While treating individuals, the veterinary focus remained on a wider good, of populations of humans and animals. This approach allowed the sacrifice of individuals to vivisection, or animal experimentation, in order to advance understandings of diseases and treatments. The Dick Vet, as well as other veterinary schools and practices, perceived themselves as crucial to informing public health debates and participating in actions to safeguard public health in the early to mid-twentieth century (Newspaper Cuttings 1930-1951). This positioning has come round again, apparent in the growing area of One Health, with its partnerships between medicine and veterinary medicine, primarily focused on zoonotic disease transmission and antimicrobial resistance.  

Edinburgh Zoo contended with outbreaks of avian TB, which appears to be the reason for an increase in TB cases from 1936 to 1940 (RZSS Register of Deaths). In some cases, zoo records include the location of TB in the animals’ bodies, making it possible to identify what was most likely avian TB.  

TB cases noted in Death Records from 1915-1945

Ruminants can become reservoirs for the disease, with potential to lead to widespread infections in other zoo animals through faeces. TB in the lungs caused animal deaths, between 1936 and 1945, across a wide range of species at the zoo (RZSS Register of Deaths). Postmortems undertaken by the Dick Vet reveal further details of disease but do not name specific TB bacteria involved (see, for example, Royal (Dick) Veterinary College Postmortems 1941-43). Unlike cows, who were killed if they tested positive for bTB, Edinburgh Zoo animals were not tested and culled, instead dying of various forms of TB, as it may have been difficult to identify a cause of illness until postmortem.

As with many other zoos, RZSS had roots in conceptions of zoos as places for public recreation or entertainment, showcasing species exotic to Scotland, while also providing what they considered health and wellbeing benefits to people through engagement with wildlife; this is evident in the annual report accounts from the period of 1915 to 1945 (see especially annual reports from 1941-1945 during the war years). RZSS in the early to mid-twentieth century saw itself as equally concerned about the impact of their practices on human and animal health and wellbeing, considering captivity better for the animals than a wild life of stress and uncertainty (Gillespie 1934); the latter can be challenged within a context of wild animal trade and a well-known history of colonial menageries and profit-driven enterprises (Flack 2018, Rothfels 2008). Many animals, live caught from India and colonial countries in Africa, perished during transport, failed to thrive upon arrival and/or direct contact with humans left them vulnerable to zoonotic diseases, such as TB (Hochadel 2022). Thus, Edinburgh Zoo, alongside other zoos in Europe, maintained an ethos tied to human health and wellbeing benefits of engagement with wild animals and linked to a colonial past. 

Finally, SSPV focused on individuals, both human and other animal, to challenge what they considered the cruelty of vivisection and vaccinations built on animal experimentation. They saw other animals as deserving of compassion and fair treatment, in large part based on Evangelical Christian ideals and the positioning of women who drove campaigns (see Our Fellow Mortals magazines, an example in the references). SSPV archival materials reveal a concern for conditions of living and preventative measures that would keep bodies healthy, both human and animal. For instance, James C. Thomson, an influential figure for the SSPV, who developed nature cure approaches in Edinburgh, described the strain that milk production placed on dairy cow bodies in industrial farming, which resulted in hypocalcaemia (Thomson 1943); milk fever, caused by hypocalcaemia, was and still is a recurring illness of dairy cows, as studied by the Dick Vet and found in their archival material (see Papers Relating to Milk Fever Research). These animals became more susceptible to TB infection.

In terms of their anti-vaccination stance, the SSPV foreshadowed current anti-vaccination sentiment, as described in the US context:  

‘Concerns about contamination, distrust in the medical profession, resistance to compulsory vaccination, and the situated locality of vaccine resistance are themes that resonate with contemporary vaccination skepticism. Recently, commentators on vaccination resistance have tended to see these themes as historically new in the late 20th century … Yet that view is historically inaccurate, and it obscures the fact that there has always been resistance to vaccination. (Hausman et al 2014)

But SSPV also had a unique positioning in their concern for animal welfare and health in relation to vaccination (not just human medical freedom) and other practices employed to treat or understand human diseases. They aligned with RZSS in their focus on the human health benefits of connection to nature, while diverging in their concern regarding use of animals, which often caused animal suffering. Thus, their perspective appears to foreshadow elements of the contemporary One Welfare approach, attempting a decentring of the human.  

Collection stores at the Main Library

Through engagement with archival materials, we can see how animal welfare held a central place in work of the Dick Vet, RZSS and SSPV, and debates occurred in Scotland between 1915 and 1945 around the ways in which animal welfare, or the treatment of animals and their wellbeing, related to public health. This is not new debate and ideas now contained within current conceptions of One Health and One Welfare were expressed throughout the twentieth century. Historical records in the Dick Vet, RZSS and OneKind archives provide a wealth of relevant perspectives to be mined, to understand origins or precursors of concepts and to potentially inform equitable ways forward.

Please get in touch if you’d like to know more details about this project! The next blog post will shift our focus to women and how they feature uniquely in archival materials.

Archival Research on Bacterial Infections, Part 1: One Health, One Welfare and Tuberculosis

This week, I introduce my short research project on bacterial infections, with specific focus on tuberculosis (TB) as a zoonotic disease; these are diseases that can move from one animal species (including humans) to another. After spending two and a half months immersed in archival materials, I realised that this focus provided a good means to explore different ideas of animal welfare and how welfare was implicated in public health issues between 1915 and 1945.

The OneKind archives in store at the CRC

The Royal (Dick) Veterinary College, Royal Zoological Society of Scotland and OneKind animal charity (formerly the Scottish Society for the Prevention of Vivisection or SSPV), all approached infectious disease management in ways that defined welfare and cruelty differently. While I revealed these differences in my research, I also considered whether espoused ideas could be seen as precursors to contemporary conceptions of One Health or One Welfare. Here I’ll share a quick introduction to One Health and One Welfare and a bit of background about TB in the UK. Later this week, I’ll share my findings on this topic based on archival research.

What do we mean by One Health and One Welfare?

The concept of One Health (OH) was first referred to in 2003 as response or means to address the public health threat of zoonotic diseases. OH has been championed primarily by veterinarians (Cassidy 2018). The international One Health High Level Expert Panel developed a globally recognised definition: 

One Health is an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems.  It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and inter-dependent.’ (Mettenleiter et al 2023)

But One Health has been criticised for being too anthropocentric and not adequately attending to animal welfare and wellbeing (Lindenmayer and Kaufman 2021). One Welfare is meant as a corrective and focuses on interconnections between animal welfare and wellbeing, human wellbeing and the environment, thus extending the One Health focus only on health (Pinillos 2018). The One Welfare Framework, developed by Pinillos (2018), includes themes that give equal or at least greater consideration to animals alongside humans in environments. These themes include:

  • interconnections between animal abuse, human abuse and neglect;
  • socio-economic aspects linked to animal welfare;
  • connection between farm animal welfare, farmer well-being and food security;
  • conservation, sustainability and connections between biodiversity, environment and animal-human wellbeing.

One Welfare also focuses on prevention, to understand ‘root causes and drivers’ of risks to health and wellbeing. I considered these concepts when investigating organisational approaches to animal welfare and human health in the archival materials. Now a brief introduction to the history of TB in the UK.

Background: TB in the UK

TB is an ancient disease in the context of Europe and the UK. There are three types of TB that feature in the archival collections: Mycobacterium tuberculosis (TB) which causes disease in humans and can infect other mammals and parrots (Schneider et al 2008), M. bovis or bTB which causes TB in cows and infects humans and other animals through meat and milk product consumption (McFarlane 1990), and M. avium which primarily afflicts birds but can occasionally infect humans and other animal species (Blessington et al 2021).

Many individuals are resistant to serious infection by M. tuberculosis, but certain factors cause vulnerability including living conditions, diet (malnutrition), age and suffering from other illnesses (McFarlane 1990). This type of TB became most virulent in the nineteenth century in the UK and Europe in overcrowded conditions with poverty but declined in the twentieth century; increases occurred during the world wars due to increased conditions of impoverishment (Glaziou et al 2018). Edinburgh championed a campaign to fight TB that became the root of the national campaign in the late nineteenth century (McFarlane 1990). In 1882, Robert Koch identified and isolated the tubercle bacillus, grew it in animal serum and introduced it into laboratory animals who then developed TB (Barberis et al 2017). A vaccine, Bacille Calmette-Guerin (BCG), discovered by scientists at the Pasteur Institute, derived from a bovine TB strain, was trialled successfully on animals in 1919, following Koch’s work, with use of the vaccine on infants by 1924 (Luca and Mihaescu 2013). BCG  successfully prevents disease in children, but immunity diminishes with time so that adults have weakened protection (Fatima et al 2020). Despite a vaccine and attempts to improve upon it, TB has not been eradicated, still considered a public health issue in Scotland (Public Health Scotland 2023).

Northern Whig & Belfast Post, 1925, Royal (Dick) Veterinary College, Newspaper Clippings 1923-1929 (EUA IN2/6/1)

Cases of bovine TB were lower than human TB historically in human populations in the UK, but concerning from a public health perspective due to child deaths (Waddington 2004). Infected cow’s milk and meat caused infection in humans. Milk, if properly pasteurised, was safe to drink, but most milk was unpasteurised up to 1939, with an anti-pasteurisation campaign influential between 1900 to 1930 (Atkins 2000); divisions formed even within the medical profession, with some doctors for and some against pasteurisation. The UK Government ‘Milk in Schools’ programme, to address malnourishment in British children, a public health issue, led to a greater number of children at risk of contracting bTB from infected milk during this time period (Atkins 2000). Other measures to reduce public health risk from bovine TB, aside from pasteurisation, developed from 1920 included a skin test for cattle and in the 1950s, compulsory testing of cows and culling of those positive for TB (Waddington 2004).

Finally, while transmission to humans has been considered low risk, M. avium infects those with compromised immune systems, and has been considered a public health concern. A vaccine has not been developed for avian TB, and treatment with antibiotics could lead to antimicrobial resistance, so responses to infections in farmed birds such as chickens, for instance, involved killing infected birds and preventative measures (Kwaghe et al 2015).

Look out for the next blog post where I’ll share some of my findings!

Research and the One Health Archival Collections

Hello, I’m Elizabeth, the postdoctoral researcher on the One Health archival project! During the Wellcome Trust grant, I was employed for five months from October 2023 to the start of March 2024 to develop academic engagement with the archival material and undertake a short research project. Thanks to funding from Heritage Collections, I can continue for two more months until early May, focusing on engagement and another short research project. I will spend the next month blogging to introduce research strands identified across the collections that might be of interest to researchers/students, share short research projects I’ve undertaken, and our academic engagement activities so far. By doing this, you’ll really get a flavour for the richness of the collections as a resource for research.  

RZSS Animal Arrival and Death Records

Just a quick introduction to my background! I have a PhD in environmental policy and ethics, with focus on biodiversity conservation, but more recently I have undertaken degrees in anthropology, in the subfield of anthrozoology, where we study human-animal relationships and interactions, considering socio-cultural, political contexts. My previous research projects have primarily involved captive wild animals in zoos and circuses, compassionate conservation and human-wildlife conflict and coexistence. I had previously undertaken research on Charles Darwin that introduced me to digital archival research, but I had not engaged directly with archival material – this is an exciting, new world to be immersed in. Thank you to Fiona Menzies, Project Archivist and lead, for introducing me to it!

Me and my cat, Reilly, who is known well at the Dick Vet due to his many rare health conditions!

The archival materials are fascinating in so many respects, windows into specific organisations in Edinburgh and how they were located within wider debates in Scotland and the UK about animal health, welfare, conceptions of animal cruelty, public health and the roles and perceptions of women in caring within communities, for instance. More on research possibilities in the next blog post! In the meantime, do get in touch if this post has already piqued your interest: you can comment on the blog post or reply to me directly at elizabeth.vandermeer@ed.ac.uk.
