I am particularly interested in diseases that spread between humans, domestic animals and wildlife and am an advocate of interdisciplinary research (that which brings together people with different areas of expertise to tackle disease problems together).
I work with colleagues at the Animal and Plant Health Agency (APHA, formerly the AHVLA) to research novel ways for detecting TB (tuberculosis) in badgers. This is important because the same form of TB is found in cattle. You can read details about this project here and read a magazine article on the subject here.
My main research Interests are:
- Design, refinement and evaluation of animal and public health surveillance programmes
- Cleverer use of diagnostic tests at the individual and group level to better inform the management of diseases in animal populations.
- Identifying animals or groups that are responsible for a disporoportionate amount of disease transmission. Targeting these individuals can result in much more effective disease control.
- Understanding and managing risks of infectious disease transmission to/from humans, livestock and wildlife.
To hear more about the research I am involved in, you can listen to two podcasts (see links at the bottom of the "Selected Publications" tab).
In addition to working with colleagues at the RVC, I am involved or have recently been involved in collaborative research projects with scientists at the University of Cambridge, UK (TB in meerkats), Animal Health and Veterinary Laboratories Agency, UK (disease surveillance evaluation), Animal and Plant Health Agency, UK (diseases in wildlife, particularly TB in badgers) and the University of Cape Town, South Africa (diseases in wild baboons).

Highlights: Grey squirrels damage trees in the UK by stripping bark and eating the underlying phloem. Squirrel motivation for damage is, however, unknown. Damage can result in deterioration of timber quality and a significant economic toll on the forestry industry. A better understanding of what motivates grey squirrels to strip bark may enable a preventive approach to be developed. This paper reviews the evidence that squirrels damage trees to ameliorate a calcium deficiency.

Highlights: Current methods for diagnosing tuberculosis (TB) in live badgers are not very accurate. One way to improve this might be to diagnose infection at the group (rather than the individual) level. In this research paper, we model field data spanning 7 years containing over 2000 sampling events from a population of wild badgers in southwest England to quantify the ability to correctly identify the infection status of badgers at the group level. We explore the effects of variations in: (1) trapping efficiency; (2) prevalence of infection; (3) using three diagnostic tests singly and in combination with one another; and (4) the number of badgers required to test positive in order to classify groups as infected. We use our findings to make practical recommendations which may help improve TB diagnosis (and therefore control) in badgers.

(2016) Beyond aggression: testosterone’s modulation of social interaction among subordinate males in the cooperatively breeding meerkat. Hormones & Behavior 78: 95-106.
Highlights: In male mammals, the hormone testosterone affects reproduction, social dominance, and aggressive behaviour. We examined the effect of temporarily blocking the effect of testosterone in male meerkats. We found that testosterone plays an important role in mediating social interactions, which in turn has the potential to affect the chances of diseases being transmitted between individuals.

Highlights: We present the entire genetic sequence (the DNA code) from the bacterium which causes tuberculosis (TB) in meerkats in southern Africa, and show how it is related to the bacteria which cause TB in other species.This is a new breakthrough in our understanding of the evolution of this ancient disease.

Highlights: We looked at the ability of 59 existing recording systems to generate accurate and reliable estimates of the frequency of important health conditions in the dairy herd of Great Britain. Johne’s disease, bovine viral diarrhoea, mastitis and lameness were the most commonly recorded conditions, but there were considerable differences in the coverage, implementation and objectives of the systems evaluated. We found that even though the individual systems could provide reliable estimates of dairy health for individual farmers, none of the systems alone could provide accurate and reliable estimates for any of the conditions of interest at national level.

Highlights: This study discovered factors which increase the chance that a cow will test positive for TB. Risk factors apepar to be related to the time since infection, the strength of the challenge of infection and the susceptibility of the animal. These findings are important because the detection of lesions and the confirmation of TB are an integral part of the overall bTB control programme in Northern Ireland. The apparent TB status of an animal can affect the way in which TB breakdowns are managed, since failure to detect visible lesions or the causal bacteria can lead to a less stringent follow-up which may mean the disease is not controlled optimally.

Highlights: We investigated 11 outbreaks of a virus affecting small ruminants in Heilongjiang Province, China in early 2014. We found that the most likely source of the virus that caused these outbreaks was animals introduced from livestock markets. This research is a result of collaborations formed between RVC staff and Chinese researchers during the ongoing Field Epidemiology Training Programme for Veterinarians in China, for which RVC is the lead training institution.

Highlights: We developed an inventory of livestock health surveillance programmes in GB in 2011. We found livestock health surveillance funding to be unevenly distributed between species: the vast majority (approximately 94 per cent) was spent on cattle diseases (tuberculosis surveillance accounted for most of this expenditure). Consequently, surveillance an effort in GB appears heavily skewed towards regions with high cattle densities, particularly high-prevalence tuberculosis areas such as the southwest. Also see this editorial in the same edition of Vet Record which discusses the importance of this paper's findings.

Highlights: The organism that causes tuberculosis in meerkats (Suricata suricatta) has been poorly characterised. Our genetic analysis showed it to be a new species of bacteria which is epidemiologically and genetically unique. We name this new species as Mycobacterium suricattae.

Highlights: Camera traps were used to record interactions between livestock (cattle and domestic pigs) and wildlife (red deer and wild boar) over 12 months in south-central Spain. Direct contacts between wildlife and livestock were rare but indirect interactions were far more common, which reflects what has been found in other countries (e.g. badgers and cattle in UK: see reference 16 below). Areas near water were a hotspot for interactions between species which suggests that preventing animals from aggregating at such areas might reduce transmission risks of diseases such as bovine tuberculosis.

Highlights: Widespread movement of animals and their products around the world increases the risk of international disease spread. There is, therefore, a need for exchange between countries of comparable information about disease incidence; the exchange must be based on a common understanding of surveillance approaches and how surveillance systems are designed and implemented. This paper establishes agreed-upon definitions of surveillance terms as a first step in achieving this standardisation, to enhance transparency and confidence in international animal health surveillance.

Highlights: We investigated interactions between badgers and cattle using automated proximity loggers. Direct contacts between badgers and cattle at pasture were very rare despite ample opportunity for interactions to occur. Indirect interactions (visits to badger latrines by badgers and cattle) were much more frequent than direct contacts. Our findings suggest that indirect contacts might be more important than direct contacts in terms of transmission of diseases such as TB. See also this feature in The Ecologist magazine.

Highlights: Animal health surveillance protects animal and human health. Surveillance systems should be regularly evaluated to determine if they are providing useful information and to identify needed improvements. This paper introduces SERVAL, a SuRveillance EVALuation framework developed at RVC and AHVLA. SERVAL is novel and generic which makes it suitable for the evaluation of any animal health surveillance system.

Highlights: We investigated the possibility that domesticated egg-laying hens form distinct 'friendships' by examining whether or not individual chickens were particular about who they spent most time with. This is not so odd a question as might be thought: in humans and other species, friendships have been shown to enrich life positively, buffer against stressful experiences and even improve reproductive success. However, we found no evidence to suggest that modern hens reared in commercial conditions form such friendships, even when they are housed in small groups where it is possible to know every other bird. So the answer to the question "do hens have best friends?" is: "it seems not"!

Highlights: Automated proximity loggers are increasingly being used to record interactions between animals but their accuracy and reliability remained largely un-assessed until now. We assessed the performance of these devices in the lab and in the field by fitting them to cattle and badgers and using static base stations. We demonstrate how data can be manipulated to ensure it accurately reflects real life. We make five recommendations for the effective use of proximity loggers in future studies.

Highlights: Baboons on South Africa’s Cape Peninsula come in frequent contact with humans. To determine potential health risks for both species, we screened 27 baboons from 5 troops for 10 infections of public health importance. Most (56%) baboons had antibodies reactive or cross-reactive to human viruses. We conclude that spatial overlap between these species poses low but potential health risks.

Highlights: We reviewed how epidemiologists around the world evaluate disease surveillance for human and animal health conditions. We found most could do better, for example by assessing more attributes and choosing the ones they do assess more systematically. We discovered that economic assessment is rarely done. We make recommendations to improve surveillance evaluation.

Highlights: We studied how social interactions between wild meerkats affect tuberculosis transmission in the Kalahari desert. We found that grooming was more risky than aggressive interactions. These results are rather neat because they offer an explanation as to why not all animals in a group become infected and why socially dominant individuals can by their behaviour be effectively protected from becoming infected.

Highlights: We examined social networks in and between groups of wild meerkats. Despite some patterns in who grooms whom, who competes for food against whom, and who is aggressive to whom, we found considerable variation between groups. We conclude that researchers should be cautious about treating individuals with similar attributes as functionally similar. This is relevant to studies of disease transmission where we often generalise or make conclusions on disease risk based on attributes such as age, sex and dominance status.

Highlights: Accurate diagnosis of tuberculosis (TB) is notoriously difficult in live animals. We used a Bayesian approach to determine how best to use three TB tests in live-sampled badgers. We devised a way to combine results from each test leading to an estimated diagnostic accuracy of 93% meaning approximately 13 out of 14 animals had their true infection status correctly classified from samples collected on a single capture. This method represents a marked improvement on the current procedure for diagnosing TB in live badgers and could be applied to improve accuracy of TB diagnosis in other species.
7. Drewe, J.A. (2010) Who infects whom? Social networks and tuberculosis transmission in wild meerkats Proceedings of the Royal Society B 277: 633-642.
Highlights: Transmission of infectious diseases is strongly influenced by who contacts whom. Here, I use a social network approach to examine the relative importance of a range of social interactions in spreading disease between meerkats. Contrary to predictions, the most socially interactive animals were not at highest risk of acquiring infection, indicating that in addition to contact frequency, the type and direction of interactions must be considered when quantifying disease risk.

Highlights: While the incorporation of mathematical and engineering methods has greatly advanced in other areas of the life sciences, they have been under-utilised in the field of animal welfare. In this review we explore the scope of such analytical methods as behavioural indicators of welfare. We discuss four classes of analyses that can be used to quantify aspects of behavioural organization: fractal analysis, temporal methods, social network analysis, and agent-based modelling and simulation. We highlight the potential applications and limitations of these methods in the assessment of animal welfare.

Highlights: Knowledge of the how animals interact is important for understanding the evolution of cooperation, transmission of disease, and patterns of social learning, yet little is known of how environmental, ecological, or behavioural factors relate to such structures within groups. Here, we investigate these factors in groups of wild meerkats. We found that the pattern of interactions between group members is not consistent but instead depends on general attributes of the group, the influence of specific individuals, and ecological factors such as parasite load.

Highlights: We test whether social network analysis is useful for understanding patterns of contact between groups of animals. We looked at how stable interactions are over time and how different types of interactions between groups differ and relate this to risk of disease transmission. Spatial analysis of meerkat social networks reveals that roving male meerkats preferentially visit nearby groups rather than better groups (those with more females) further away.

Highlights: We use a Bayesian mathematical approach to work out the diagnostic accuracy of tests for TB in meerkats. Individually the tests were not particularly useful but using them in combination increased the accuracy of diagnosis to a level high enough to be valuable. [This approach has subsequently been adopted by other researchers working on TB in other species.]

Highlights: This paper (illustrated with lots of colourful photos) describes a detailed investigation into the pathology of TB in meerkats. The histological characteristics of the tuberculous lesions, together with the gross pathology and the wide range of body systems affected, suggest that TB in meerkats is acquired principally via the respiratory and oral routes, whereas excretion is most likely via the respiratory tract and suppurating skin wounds. The findings of this study provide information on the transmission, pathogenesis and epidemiology of TB in meerkats that is likely to be relevant to the understanding of M. bovis infection in other social mammal species such as the Eurasian badger.

Highlights: Reed beds are increasingly being planted to act as filters of dirty water. We examined if they remove harmful pathogens such as Mycobacterium avium – the agent that causes TB in birds. We discovered that they can effectively remove M. avium from the water through a combination of sedimentation and adsorption onto vegetation stems. The results of this study show that constructed reed beds composed of a settlement lagoon and one or more vegetation beds can act as valuable and ecologically friendly tools in the environmental control of avian TB.

Highlights: In this invited editorial I examine an important aspect of the skin test for diagnosing TB in cattle: how likely is it that the test result will be negative in cattle without the infection? (This is known as the specificity of the test and is less commonly considered than the the sensitivity of the test, which is the likelihood that an infected animal will test positive.) The editorial discusses a recently published paper on the subject by Goodchild and others which is published here.

Highlights: Infectious diseases can have major impacts on populations, from global pandemics to localized outbreaks. Believe it or not, animals have social networks too (though they are more often based around things such as grooming or aggression rather than who they befriend on Facebook). This chapter describes how the structure of animal social networks can affect disease spread, and how diseases can affect social network structure. This has important implications for how we understand and manage infectious diseases.

Highlights: Hazards can be defined as pathogens, substances, or activities that may lead to adverse health consequences (such as disease). Hazards in meat have a range of negative effects on the animals themselves and on human consumers. It is essential to control such hazards because the international trade in meat means outbreaks can rapidly affect many countries. Mitigation of risks arising from meat-borne hazards involves a careful balance of surveillance and intervention strategies. This article discusses the range of approaches that are available to reduce the risks of hazards in meat, using a range of examples from around the world.

Highlights: A review of the main molecular techniques and their application for gaining hidden insights into the epidemiology of TB due to M. bovis in animals (including humans). Includes examples of investiagtions to trace the geographical origins and transmission of M. bovis, and discusses the use of epigenetics to aid our understanding of potential risks associated with this pathogen.

(2009) Wildlife population structure and parasite transmission: implications for disease management In: Management of disease in wild mammals Eds: R.J. Delahay, G.C. Smith and M.R. Hutchings. Springer Publishing, London. pp 9-29.
Highlights: Emerging infectious diseases have become an important challenge for wildlife ecologists and managers. Management actions to control these diseases are usually directed at the parasite, the host population, or the environment. Control methods directed at the host population, however, remain limited (e.g. vaccination, population reduction, test-and-remove) and have often been implemented without due consideration of how host ecology and behaviour may influence disease dynamics. This chapter highlights how host population structure and social organisation affect parasite transmission and prevalence. Future control efforts may be improved by focusing on subsets of individuals, areas, environmental factors, or times of year that are most important in the propagation and persistence of a pathogen.&
I teach a broad range of topics relating to epidemiology and wildlife disease ecology on these courses:
BSc in Bioveterinary Science (including the popular final-year module "Epidemiolgoy: The bigger picture")
BSc in Comparative Pathology
I teach on the Field Epidemiology Training Programme for Veterinarians in China. I also deliver workshops internationally for MSc Veterinary Epidemiology and Public Health distance learning students.
I collaborate with colleagues working in allied disciplines, for example Public Health England/APHA/Chartered Institute for Environmental Health (Zoonoses roadshow).
I run science seminars in local schools to encourage pupils to be interested in careers in science, as part of the RVC outreach programme. School classes curious about science can attend interactive masterclasses that I hold periodically at RVC. A typical topic is 'Deadly contacts: how your social network could trigger the next pandemic'. Contact the RVC outreach office if you would like more information.
Three times a year I head eastwards to teach as an international trainer on the Field Epidemiology Training Programme for Veterinarians in China. This includes field studies and workshops to explore the interface between animal and public health in China and ways to improve collaboration across disciplines.
Previously I have delivered workshops on epidemiology (including topics such as surveillance, risk analysis and outbreak investigation) at the Faculty of Veterinary Medicine and Animal Science at the University of Peradeniya in Sri Lanka, and at the Southern African Centre for Infectious Disease Surveillance (SACIDS) summer school in Morogoro, Tanzania. It was great to meet students who attended from across eastern and southern Africa, including: Tanzania, Malawi, Zimbabwe, Mozambique, Zambia, Botswana and Democratic Republic of the Congo.
These workshops link to the RVC's distance learning MSc course in Veterinary Epidemiology and Public Health.
- Implications of land use changes on wildlife behaviour and infectious disease transmission to people (April 2014). Highlights: A short interview in which we discuss research we are conducting in Malaysia looking at how land use changes influence the behaviour of wild monkeys and their interactions with humans, with implications for the transmission of infectious diseases such as malaria. This research is funded by a fellowship grant from the London International Development Centre and is being conudcted researchers from the RVC (Julian Drewe and Martha Betson) and the London School of Hygiene and Tropical Medicine (Kimberly Fornace). You can read more about the project here.
- Wildlife Reservoirs of Disease and Tuberculosis (January 2010, 6.1MB, MPEG-4, also available via iTunes or the RVC eMedia website: RVC podcast no. 42). Highlights: Badgers are often blamed for the persistence of tuberculosis in cattle herds in parts of the UK. Here Dr Julian Drewe describes his research on the dynamics of UK badger populations and meerkat communities in Africa and the potential importance of this for the spread of TB within and between species.
How do we solve a problem like tuberculosis in badgers? Here's a recent article I wrote for the American magazine The Wildlife Professional which outlines some ideas.
