This thesis presents an Actor-Network Theory (ANT) inspired analysis of sheep scab in Scotland. Sheep scab is caused by scab mites, and it has a long history in terms of its legislation and available treatments in the UK. In 2010 it became a notifiable livestock disease again in Scotland. Even though sheep scab is studied by natural scientists and economists, it remains unclear how scab is understood by sheep practitioners. This means that the stories, practices and knowledges of sheep practitioners who work at the forefront of sheep scab (in terms of its recognition, diagnosis, treatment and notification) remain absent from the political arena. However, their activities shape how rules and regulations are used. An ANT approach proved helpful for this research, because it allows the researcher to follow connections. The connections followed are sheep scab stories and practices. This research therefore has the following main question: How are multiple sheep scab situations enacted in Scotland? Multi-sited ethnography is the methodology used for this research, and semi structured interviews and field observations were done to get in-depth information about sheep scab situations in Scotland. In total 47 interviews, and 14 observations were done from 2013-2014 with diverse respondents ranging from farmers, veterinarians, slaughterhouse employees and natural scientists. This thesis contributes empirically and theoretically to human-animal studies (HAS). The empirical findings are that the notification legislation for sheep scab is rarely used; sheep scab diagnoses are rarely done; and finally, sheep practitioners trust their own situated knowledges of sheep scab. The theoretical contribution is a reworking of ANT to make it more suitable for studying sheep scab. In particular I rework ANT's confusing terminology; its tendency to reduce entities to their effects; and I include concepts from livestock disease literature that proved particularly helpful.

Undernutrition in prevalent in Aboriginal communities, in utero, infancy and childhood. It influences childhood morbidity and mortality and growth patterns. Undernutrition and poor socio-economic status also contribute to endemic and epidemic infectious disease, including scabies and streptococcal infection. It has been suggested that early undernutrition, and streptococcal and scabies infection are risk factors for renal disease, which is at epidemic levels and increasing. This thesis examines the prevalence of undernutrition in newborns and infants in an Aboriginal community over time, and its impact on childhood growth and child and adult renal markers. The association between skin lesions, streptococcal serology, post-streptococcal glomerulonephritis (PSGN) and renal markers as evaluated through a community wide screening program in 1992-1995 is also examined. Birthweights have increased since the 1960s, but they are still much lower than the non-Aboriginal values. Weights in infancy have decreased since the 1960s. At screening in childhood stunting was common, reflecting the presence of long-term poor nutrition in infancy. In both adults and children, birth weight and infant weights were negatively associated with albuminuria measured by the albumin to creatine ratio (ACR).

Skin infections by the ectoparasitic mite Sarcoptes scabiei are a preventable source of morbidity worldwide. While scabies affects all socioeconomic sectors, it is especially prominent in the developing world where crowding, poor hygiene, and limited access to basic health care are commonplace. Mass eradication efforts of this parasite have historically been hampered by delivery and compliance issues surrounding topical standards of care. There have been advances in eradication over the last decade due to the expanded use of oral Ivermectin for the treatment and prevention of ectoparasites such as scabies. Previous research focused on various treatment aspects of the disease, yet most identified the need for basic scabies health education to accompany future studies to improve program sustainability and the overall health literacy of target populations. The Virginia College of Osteopathic Medicine sponsors a public health clinic in Veron, Dominican Republic that reports a high prevalence of scabies infections among its general patient population. The lack of any means of direct measurement, proper intervention, or control raises concerns that long-term infection may lead to multiple other secondary disease sequelae. The Veron Scabies Eradication and Education Program was designed to address this deficiency and build on previous studies related to this problem by using a novel treatment and education protocol. The purpose of this research was to identify, treat, and prevent primary and secondary health problems due to long-term scabies infection in the community of Barrio Nuevo, Veron, Dominican Republic in order to provide long-term sustainable eradication through a researcher-designed health education program and medical service protocol. Participants continued typical daily life while interventions and education were monitored to detect change over a 9-month timeline using selected measurement intervals to test multiple scabies disease and knowledge objectives and related hypotheses. Following this basic protocol, the following scabies markers were evaluated at baseline: subject demographics, scabies diagnosis and treatment history, baseline treatments and reported side effects, and scabies education pre-test results. The following scabies markers were also assessed at baseline and reassessed at 2 weeks, 1 month, 2 months, 8 months, and 9 months: risk and prevention behaviors, symptomatology, skin exam findings, and scabies education post-test results. There was a statistically significant post-intervention improvement in scabies markers when compared to pre-intervention values (p<0.05). This study demonstrated that a community scabies program involving large-scale treatment and education can provide rapid and long lasting improvements to the health of a highly endemic population. Community-wide scabies eradication is possible with the appropriate level of structure and support using low cost medication available to the health care system that serves Veron, Dominican Republic. Given the efficacy and safety profile of Ivermectin demonstrated in this study and substantiated by others, it is recommended that the Dominican Republic Ministry of Health consider adopting Ivermectin as the standard of care for scabies treatments and enforce an existing formal ban on Lindane products. The protocol from this research should be considered for adoption to provide a sustainable, practical, self-sufficient model for improved health outcomes, health behaviors, and health literacy. Future studies should replicate this research to determine validation in other settings, cultures and situations, build on the findings by exploring additional variables related to environmental risk factors, and continue to develop interventions that promote health education and enhance clinical practices. / Ph.
