Sigma factor n, liaison to an ntrC and rpoS dependent regulatory pathway controlling acid resistance and the LEE in enterohemorrhagic Escherichia coli
(Public Library of Science (PLoS), 2012)
Enterohemorrhagic Escherichia coli (EHEC) is dependent on acid resistance for gastric passage and low oral infectious dose, and the locus of enterocyte effacement (LEE) for intestinal colonization. Mutation of rpoN, encoding ...
Mycobacteria, metals, and the macrophage
(Wiley, 2015-03)
Mycobacterium tuberculosis is a facultative intracellular pathogen that thrives inside host macrophages. A key trait of M. tuberculosis is to exploit and manipulate metal cation trafficking inside infected macrophages to ...
Shiga toxin 2 overexpression in Escherichia coli O157:H7 strains associated with severe human disease
(Elsevier, 2011-12)
Variation in disease severity among Escherichia coli O157:H7 infections may result from differential expression of Shiga toxin 2 (Stx2). Eleven strains belonging to four prominent phylogenetic clades, including clade 8 ...
PPE surface proteins are required for heme utilization by Mycobacterium tuberculosis
(American Society for Microbiology, 2017-03-08)
Iron is essential for replication of Mycobacterium tuberculosis, but iron is efficiently sequestered in the human host during infection. Heme constitutes the largest iron reservoir in the human body and is utilized by many ...
