ABSTRACT Cryptosporidium spp. are important enteropathogen protozoan parasites that infect humans and other animals throughout the world. Cryptosporidiosis in cattle industry leads to considerable economic losses due diarrhea, dehydration, growth retardation, weight loss, possibly death, however, data on occurrence ofCryptosporidiumspp. Colombia limited. Therefore, this study aimed investigate ...
The gut microbiota plays an important role in host health, in particular by its barrier effect and competition with exogenous pathogenic bacteria. In the present study, the competition of Bifidobacterium pseudolongum PV8-2 (Bp PV8-2) and Bifidobacterium kashiwanohense PV20-2 (Bk PV20-2), isolated from anemic infant gut microbiota and selected for their high iron sequestration properties, was in...
Yersinia pestis is the etiological agent of plague, one of the most devastating diseases in human history. Because of the identification of the plague bacillus, the understanding of its epidemiological cycle, and the advent of efficient antibiotic therapies, the death toll due to the plague has dramatically decreased over the last 100 y. However, this disease has never been eradicated, and beca...

Both human and murine neonates are characteristically highly susceptible to bacterial infections. However, we recently discovered that neonatal mice are surprisingly highly resistant to oral infection with Yersinia enterocolitica. This resistance was linked with activation of both innate and adaptive responses, involving innate phagocytes, CD4+ cells, and B cells. We have now extended these stu...
Studies of diarrheal etiology in low- and middle-income countries have typically focused on children presenting with severe symptoms to health centers and thus are best equipped to describe the pathogens capable of leading to severe diarrheal disease. The Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED)...
Members of the genus Listeria provide a model for defining host responses to invasive foodborne enteropathogens. Active translocation of Listeriamonocytogenes across the gut epithelial barrier is mediated by interaction of bacterial internalin (InlA) and its species-specific host receptor, E-cadherin, whereas translocation across Peyer’s patches through M-cells is InlAindependent. To define mic...
