Salmonella species are known to initiate infection of mammalian hosts by penetrating the
intestinal epithelium of the small bowel. These bacteria preferentially interact with Peyer's …

Phylogenetic trees and data are often stored in incompatible and inconsistent formats. The
outputs of software tools that contain trees with analysis findings are often not compatible with …

Acute pyelonephritis, a complication of Escherichia coli bacteriuria, must represent a
bacterial invasion through the kidney epithelium. To study this process, we overlaid bacterial …

Inductively coupled plasma/optical emission spectrometry (ICP/OES) is a powerful tool for the
determination of metals in a variety of different sample matrices. With this technique, liquid …

RUFFLES are specialized plasma membrane ultrastructures of mammalian cells thought to
be integral to growth, development and locomotion 1–4 . Induced by growth factors 5–8 , …

▪ Abstract The lifestyle of bacterial pathogens requires them to establish infection in the face
of host immunity. Upon entering a potential host, a variety of interactions are initiated, the …

Campylobacter pylori, a suspected agent of gastritis and peptic ulceration, rapidly hydrolyzes
urea. Because urease serves as the basis of detection of the organism in gastric biopsies …

Salmonella typhimurium penetrate intestinal epithelial cells during infection. In vitro studies
reveal that the availability of oxygen during bacterial growth decreases their capacity to …

The glial cells missing (gcm) gene in Drosophila encodes a novel nuclear protein that is
transiently expressed early in the development of nearly all glia. In loss-of-function gcm mutant …

Salmonella typhimurium requires a type III secretion system encoded by pathogenicity
island (SPI)-2 to survive and proliferate within macrophages. This survival implies that S. …
