Human PMN were mixed with S. aureus aerobically and anaerobically, and it was observed that many intracellular bacteria survived incubation with high concentrations of nine commonly used antistaphylococcal agents. In marked contrast to this, low concentrations of rifampin completely killed intraleukocytic ...
Scientists already knew that people with Crohn's and colitis tend to have fewer types of beneficial bacteria in their gut microbiomes. What researchers hadn't understood is why the bacterial diversity decreased. The new results suggest some viruses may damage health not by infecting human cells, ...
C. elegans is a free-living nematode that feeds on bacteria. It is a relatively simple and genetically tractable host2, and its transparent body is well suited for visualization of development and infection processes and for in vivo monitoring of genes induced by infection. Since the innate ...
“The substance in this wound spray is completely non-toxic and does not affect human cells. Unlike existing bactericidal sprays, it does not inhibit the body’s healing process. The materials, which are simply sprayed onto the wound, can also kill the bacteria in a shorter time,” says Ed...

Their T cell receptors (TCR) can sense the concentration increase of phosphoantigen metabolites, such as endogenous isopentenyl pyrophosphate (IPP) of the mevalonate pathway or microbial 4-hydroxy-3-methyl-but-2-enyl-pyrophosphate (HMBPP) which derives from pathogenic bacteria such as Mycobacterium ...
tuberculosis as well as possible mechanisms of resistance, within the context of what is known about the b-lactam action in other bacteria. M. tuberculosis has two major mechanisms of intrinsic resistance: a highly active b-lactamase and a poorly permeable outer membrane. Within the cell wall, ...
Enterococci are gram-positive, facultatively anaerobic bacteria of the family Enterococcaceae. They were previously classified as Group D streptococci. Enterococci are found in the bowels of most humans and are commonly isolated from stool, urine and sites of intra-abdominal and lower extremity ...
Thus cells containing bacteria are directly recognized by CD8+ T cells and the bacterial lipid induces the release of a novel enzyme, granulysin, which directly kills the intracellular bacteria.
