Why do bacteria that produce a capsule have to be stained differently than bacteria without a capsule? Gram-positive and Gram-negative bacteria stain differentlybecause of fundamental differences in the structure of their cell walls. The bacterial cell wall serves to give the organism its size and ...
Our results show that phage infectiousness defines interaction modules between small subsets of phages and bacteria in function of capsule serotype. This limits the role of prophages as competitive weapons because they can infect very few strains of the species complex. This should also restrict ...

Some of our organs, including theskin, airways andlungs, andgastrointestinal tract, are effectively "open" to the outside world. The cells that line these organs, called mucosal linings, host trillions of bacteria. These bacteria, known as our "microbiota," play essential roles in keeping us ...
Proteins that envelop bacteria in S-layers can serve the same function as polysaccharides, as is seen in Campylobacter fetus and B. anthracis. Complement components C3b and C3bi are recognized by CR3 on phagocytes, and can amplify the opsonic activity of IgG antibodies. Children who lack C3,...
For inhibition studies, the plates were treated with bacterial suspension in the presence of SBA lectin or GalNAc (Sigma) at different concentrations. Detachment was carried out by addition to wells with immobilised bacteria of either soluble SBA lectin or GalNAc, followed by incubation for 40 min...
Capsules are long-chain carbohydrate polymers that envelop the surfaces of many bacteria, protecting them from host immune responses. Capsule biosynthesis enzymes are potential drug targets and valuable biotechnological tools for generating vaccine antigens. Despite their importance, it remains unknown how ...

They loaded anticancer drugs in hijacked bacteria that naturally swim along magnetic field lines and used artificial magnetic fields to navigate them to tumors. In addition, using light to control nanorobots (Table 1) and light-triggered drug delivery and release have also been the subject of ...
