Giardia duodenalis (syn. G. intestinalis, G. lamblia) infections are a leading cause of waterborne diarrheal disease that can also result in the development of postinfectious functional gastrointestinal disorders via mechanisms that remain unclear. Parasite numbers exceed 10(6) trophozoites per centimeter of gut at the height of an infection. Yet the(More)
Pertactin and filamentous hemagglutinin (FHA), proteins present on the surface of the gram-negative organism Bordetella pertussis, have been shown to contain the putative cell-binding sequence arginine-glycine-aspartic acid (RGD) and to promote eukaryotic cell attachment. The attachment of epithelial cells to purified pertactin and the entry of B. pertussis(More)
Irritable bowel syndrome (IBS) is a commonly encountered chronic functional gastrointestinal (GI) disorder. Approximately 10% of IBS patients can trace the onset of their symptoms to a previous a bout of infectious dysentery. The appearance of new IBS symptoms following an infectious event is defined as post-infectious-IBS. Indeed, with the World Health(More)
OBJECTIVE To investigate the anti-inflammatory and immunomodulatory properties of tulathromycin in vitro and in experimental models of Actinobacillus pleuropneumoniae-induced pleuropneumonia and zymosan-induced pulmonary inflammation in pigs. ANIMALS Blood samples from six 8- to 30-week-old healthy male pigs for the in vitro experiment and sixty-five(More)
Enterocyte turnover along with proper epithelial barrier function are crucial aspects of mucosal defense. Apoptosis is a highly regulated type of programmed cell death that allows for the homeostatic turnover of the epithelial layer. Recent studies have suggested that microbial modulation of enterocyte apoptosis can result in increased epithelial(More)
Giardia duodenalis infections are among the most common causes of waterborne diarrhoeal disease worldwide. At the height of infection, G. duodenalis trophozoites induce multiple pathophysiological processes within intestinal epithelial cells that contribute to the development of diarrhoeal disease. To date, our understanding of pathophysiological processes(More)
Giardia duodenalis is a prevalent cause of acute diarrheal disease worldwide. However, recent outbreaks in Italy and Norway have revealed a link between giardiasis and the subsequent development of chronic post-infectious irritable bowel syndrome. While the mechanisms underlying the causation of post-infectious irritable bowel syndrome remain obscure,(More)
