It is active against a broad spectrum of Gram-positive ... negative bacteria are resistant to nisin mainly due to impermeable outer membranes, since nisin has to incorporate itself in the bacterial ...

The cellular element includes epithelial cells ... positive bacteria. It cleaves glycosidic bonds which stabilise peptidoglycan, resulting in bacterial lysis. Gram negative bacteria have an outer ...

By analyzing E. coli protein levels, scientists found a surplus of membrane shuttle proteins that may play a role in ...

Researchers at the University of Tsukuba have reported on the structure and light energy transfer efficiency of a protein ...

Scientists have uncovered the equipment that enables bacteria to survive exposure to antibiotics: a shuttling mechanism that helps a complex of proteins pump out a wide spectrum of antibiotics along ...

Our cells do not have cell walls. Bacterial cell walls are primarily made of a unique substance called peptidoglycan, which is a mesh-like structure mostly made of two components. Glycans are long ...

Biologists converted gut bacteria into miniature protein factories that manufacture and release a sustained flow of targeted proteins inside the lower intestines. This technique solves one of the ...

Using cryo-electron microscopy, we obtained a high-resolution structure ... into the cell induces perturbations of the bacterial cell’s outer layers that are sensed by the cell-wall-anchored ...

Three of these six pathogens are antibiotic-resistant Gram-negative bacteria. Recently, antibacterial drugs against ESBL-producing Gram-negative bacteria accounted for ∼15% (2 out of 13 ...

Not all cases of non-HACEK Gram-negative bacterial endocarditis necessarily require surgical intervention. Indications for surgical intervention in patients with Gram-negative endocarditis are ...

Wall Street brushed aside President Donald Trump ... it may be more bark than bite. “We view this as a positive development given that Trump previously planned to impose a uniform 10% ...
