While regional heterogeneity in islet distribution has been well studied in rodents, less is known about human pancreatic histology. To fill gaps in our understanding, regional differences in the adult human pancreas were quantitatively analyzed including the pathogenesis of type 2 diabetes (T2D). Cadaveric pancreas specimens were collected from the head,(More)
We describe a one-dimensional probabilistic model of the role of domestic food handling behaviors on salmonellosis risk associated with the consumption of eggs and egg-containing foods. Six categories of egg-containing foods were defined based on the amount of egg contained in the food, whether eggs are pooled, and the degree of cooking practiced by(More)
OBJECTIVE To identify emerging animal and zoonotic diseases and associated geographic distribution, disease agents, animal hosts, and seasonality of reporting in the Program for Monitoring Emerging Diseases (ProMED)-mail electronic early warning system. DESIGN Retrospective study. SAMPLE POPULATION 10,490 disease reports. PROCEDURES Descriptive(More)
This population-based, retrospective study examined the susceptibility of a prosimian primate, Coquerel's sifaka (Propithecus coquereli), to Cryptosporidium spp. over a 9-yr period from 1999 to 2007 at the Duke Lemur Center (DLC) located in Durham, North Carolina. The investigation examined potential epidemiologic risk factors that could be correlated to(More)
The foodborne disease risk associated with the pathogen Listeria monocytogenes has been the subject of recent efforts in quantitative microbial risk assessment. Building upon one of these efforts undertaken jointly by the U.S. Food and Drug Administration and the U.S. Department of Agriculture (USDA), the purpose of this work was to expand on the consumer(More)
A 28-year-old Costa Rican woman presented with a 6-year history of an asymptomatic progressive localized livedo racemosa on her limbs. Histological examination revealed a lymphocytic vasculitis targeting the arterioles in the deep dermis. In addition, a distinct hyalinised fibrin ring was noted at the periphery of the vessel lumen. These findings were(More)
OBJECTIVE To evaluate the risks associated with wildlife rehabilitation and the reemergence of wildlife rabies in North Carolina through assessment of the status of knowledge and attitudes of licensed in-state wildlife rehabilitators about rabies and rabies vector species (RVS). DESIGN Questionnaire survey. SAMPLE POPULATION 672 North Carolina licensed(More)
Salmonella enteritidis (SE) is a common foodbome pathogen, the transmission of which is primarily associated with the consumption of contaminated Grade A shell eggs. In order to estimate the level of SE present in raw shell eggs, it is necessary to consider the protective effects of the egg albumin, which effectively inhibits SE growth in a time- and(More)
The nation's veterinary colleges lack the curricula necessary to meet veterinary demands for animal/public health and emergency preparedness. To this end, the authors report a literature review summarizing training programs within human/veterinary medicine. In addition, the authors describe new competency-based Veterinary Credential Responder training at(More)
Proper storage and handling of refrigerated ready-to-eat foods can help reduce the risk of listeriosis. A national Web-based survey was conducted to measure consumer awareness and knowledge of Listeria and to estimate the prevalence of the U.S. Department of Agriculture-recommended consumer storage and handling practices for frankfurters and deli meats.
