Social ecological determinants of occupational zoonotic disease exposure on Colorado dairy farms
The presence of zoonotic pathogens in dairy farms is a known risk for people that work and live in these settings. People who work or live on a farm, farm visitors, service providers, and veterinarians are the most at risks of zoonotic infections. Dairy cattle operations represent a working …

Mathematical modeling of zoonotic disease transmission under the impact of land use change
… the impact of land use change. We develop a zoonotic disease transmission model that describes spillover of Puumala virus from bank voles to humans during land conversion. Our model introduces a land conversion index to capture the dependence of the carrying capacity and the death rate of …

Zoonotic disease dynamics in displacement: A multisite case study in Sindh, Pakistan and Mafraq, Jordan
… pathogens originates in animals. These zoonotic diseases are considered a threat to public health in emergencies and displacement, linked to changes in pathogen and vector environment. Although little is known about the exact disease dynamics due to scarce evidence, the fear of zoonoses …

Predictive Analytics and Machine Learning for the Risk-Based Management of Agricultural Supply Chains
… unsafe food is sold for human consumption, and zoonotic diseases (i.e., viruses and diseases that can transfer from animals to humans through food supply chains) such as avian influenza, SARS, and COVID-19. This thesis focuses on food adulteration and zoonotic disease risks, and highlights a …

The Impact of Web-Based Visitor Education on Human-Tibetan Macaque (<i>Macaca thibetana</i>) Interactions at Mt. Huangshan, China
… macaque self-directed behaviors (SDBs), and zoonotic disease transfer. At the Valley of the Wild Monkeys in Mt. Huangshan, China, I made an educational website with site-specific information (e.g., guidelines for conduct, park rules, conservation) available and unavailable through QR codes …

The burden of zoonoses on public health: predicting zoonotic outbreaks usind different measures of pathogen richness
Zoonotic pathogens shared with wild or domesticated animals are the cause of more than 60% of human infectious diseases. These pathogens are responsible for millions of deaths annually and have resulted in costs of over a hundred billion U.S. dollars in the past three decades. Investigating …

Investigating Hfq-dependent Small Regulatory RNA, Bsr34, and Its Roles in Brucella abortus Physiology and Pathogenicity
Brucellosis, a debilitating zoonotic disease caused by the facultative intracellular pathogen Brucella, relies on rapid gene regulation for survival within host cells. Small regulatory RNAs (sRNAs), often chaperoned by Hfq, are key post-transcriptional regulators of bacterial virulence and stress …

The epidemiology of Coxiella burnetii in goats in Indiana
… bacterium and the etiologic agent of the zoonotic disease Q fever. Through the presence of an environmentally resilient small cell variant, C. burnetii can persist outside of a host in the face of extremes in temperature, humidity, and pressure. C. burnetii is considered to be ubiquitous …

Prions Propagate as Dynamic Strain Mixtures
… and inevitably fatal neurodegenerative disease in humans and other mammals. Prion disease is caused by the misfolding of a host encoded protein, PrPC, into the infectious conformation PrPSc. Phenotypic differences in disease (i.e., strains) have been observed for decades and are thought …

The identification of bovine tuberculosis in zooarchaeological assemblages. Working towards differential diagnostic criteria.
… This has impeded the understanding of animal disease in past society and, in particular, has restricted the study of systemic disease. This research tackles this by combining the disciplines of human palaeopathology and zoopalaeopathology and focusing on zoonotic disease. The primary aim of …

Comparative determination of tick burden and diversity in intensively managed wildlife estates under those with and without prescribed burning.
… and diversity. In Zambia, the role of ticks in zoonotic disease transmission is not well described, partly, due to limited available information on tick burden and diversity in ex-situ conservancies. This study aimed to compare three management systems that are currently used to control ticks in …

Influence of site and soil type on the distribution of anthrax infectious sites and the contribution of anthrax to elephant mortality in Ethosha National park, Namibia
… a soil-borne pathogen, causes the deadly zoonotic disease anthrax. Anthrax outbreaks occur frequently in Etosha National Park (ENP). ENP has nine major soil types and a distinct rainfall gradient decreasing from east to west. The sporulation success of B. anthracis is believed to be …

Understanding the epidemiology of bovine TB and potential routes of infection by elucidation of fine-scale badger behaviour and movement
Bovine tuberculosis (bTB) is an endemic, zoonotic disease in cattle and badgers, which threatens animal health, farm productivity and commercial earnings within the U.K. and Ireland. Culling of badgers has been suggested as a potentially useful protocol to reduce the incidence of bTB in badgers and …

Laimo neuroboreliozė – „didysis imitatorius“: diagnostiniai iššūkiai ir problemos /
Lyme disease is a zoonotic disease caused by Gram negative Borrelia burgdorferi sensu lato complex bacteria, most commonly B. burgdorferi sensu stricto, B. afzelii, B. spielmanii, B. garinii and B. bavariensis. It is the most common vector-borne disease in the temperate zone of the Northern …

The Potential Role for CapB in Pathogenesis of Francisella tularensis
… tularensis was also responsible for the zoonotic disease tularemia, which was usually transmitted by arthropod vectors or via contact with infected animals. Francisella tularensis subspecies novicida has been used by many researchers in genetic pathogenesis experiments to try to elucidate …

Ehrlichia chaffeensis mediates Hedgehog and Hippo signaling to activate an anti-apoptotic cellular program
… bacterium responsible for the emerging zoonotic disease, human monocytic ehrlichiosis (HME). HME is the most prevalent and life-threatening tick-borne disease in the United States. In the past two decades, the incidence of HME has increased 10-fold; however, the number of reported cases …

Presumptive identification of smooth Brucella strain antibodies in canines
Brucellosis is a zoonotic disease caused by a Gram-negative coccobacillus. There are four Brucella strains of zoonotic importance in our domestic species, subdivided by their culture phenotypes: Brucella abortus (B. abortus, B. melitensis, B. suis (smooth strains) and B. canis (rough strain). Dogs …

Prevalence of human African trypanosomiasis and its associated risk factors in Itezhi-tezhi district of Zambia.
… African Trypanosomiasis (HAT) is a debilitating zoonotic disease caused by trypanosomes which are transmitted by tsetse flies of the genus Glossina. This study aimed to determine the prevalence and risk factors of HAT in Itezhi-Tezhi (ITT) District of Zambia through active surveillance. Human …

Understanding animal movements to inform bovine tuberculosis surveillance: a framework for a targeted approach
Bovine tuberculosis (bTB) is a zoonotic disease that affects domestic and wildlife species. In recent years in the US, a novel scenario for bTB has arisen, characterized by sporadic outbreaks in cattle populations across the country and by spillover of the infection to wildlife. The cattle …

Inhibition of TFEB activation promotes Coxiella burnetii growth
… burnetii is the etiologic agent of Q fever, a zoonotic disease characterized by flu-like sickness in acute cases; endocarditis may occur and turn deadly if not treated correctly in chronic patients. Coxiella, an obligate intracellular bacterium, requires establishment of a replicative niche in …
