Such infections typically involve multiple species of bacteria, some strict anaerobes, some strict aerobes and others that are facultative anaerobes (i.e., able to grow aerobically or anaerobically). The polymicrobial nature of infections involving anaerobic bacteria is apparent in infections of the ...
O6 and O18 antigens were required for survival in human serum, the role of the capsule was less clear and linked to O antigen type. In contrast, both the K1 and K2 capsular antigens provided a survival advantage to UPEC in whole blood. In the mouse urinary tract, mutation of the O6 ...
Bacteria have various ways to sense environmental signals and to adapttheir behavior and physiology through different signaling systems.Secondary messenger signaling, amplified by enzymatic activity, rapidlytransmits a signal in the cell, resulting in allosteric functionalcontrol. Cyclic diguanosine monophospha...

Glucocorticoids (GCs) are key inducers of osteonecrosis, yet not all patients treated with GCs develop glucocorticoid-associated osteonecrosis (GAON). The factors mediating this relationship are unclear. Studies have shown that gut microbiota and their m
The inflammasome-associated proteins caspase-1, caspase-4 and NLRP3 have been emphasised to be essential in the host cell response during urinary tract infection (UTI) by regulating IL-1β release. Our aim was to investigate how the inflammasome-associated proteins regulate the cell response of ...
Fimbriae of Phytopathogenic and Symbiotic Bacteria Fimbriae are proteinaceous, filiform appendages on the bacterial cell surface that are thought to be important in attachment of bacteria to plant and other surfaces. We report here that fimbriae are common in many genera and species of p... WPC ...
The bacteria which can be commonly found in the gut of the animals are known as Escherichia coli or E.coli. These bacteria are also found in food, and some of them can also cause diseases. Diarrhea in humans can be caused by some strain ...
Results: In this study, expression of GapA-1 was shown to be well conserved across diverse isolates of Neisseria species. Flow cytometry confirmed that GapA-1 could be detected on the cell surface, but only in a siaD-knockout (capsule-deficient) background, suggesting that GapA-1 is ...
