Chronic Fatigue Syndrome and the Microbiome

Myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS), is a condition which is characterized by the onset of severe fatigue, usually between the ages of 20-40. It is often associated with other traits such as impaired memory or … Continue reading

Cancer Killing Bacteria

This blog has previously highlighted the use of genetically modified bacteria as therapeutics, including a previous post detailing its effectiveness in treating patients impaired in proper nitrogen regulation. Here we focus on recent work from Korea in which a non-virulent … Continue reading

New Advances in Endotoxin Detection

As previously discussed in this newsletter, LAL is the gold standard for endotoxin detection. However, due to limitations, such as assay interference, alternative non-enzymatic alternatives are being investigated regularly. We recently highlighted an alternative test from China dependent on the … Continue reading

Altered Gut Microbes Can Cause Obesity

Previous reports have linked the gut microbiome to obesity. A recent study has taken this a step further and provided a mechanism for how this may occur. Scientists at Yale, led by Dr. Gerald Shulman, made the observation that acetate … Continue reading

Designer Bacteria as Therapeutics

The role the microbiome plays in human disease, such as metabolic, gastrointestinal and neurological disorders, has been well-established. This has led to therapies that, just a few years ago, seemed radical, including fecal transplantation. Currently, several groups are working to … Continue reading

Low Endotoxin Recovery

Low Endotoxin Recovery (LER) is the product-specific inhibition of the bacterial endotoxin test not due to assay interference. The prevailing thought is that endotoxin detection is dependent on supramolecular structure and excipients in pharmaceutical products can destablilize endotoxin complexes, leading … Continue reading

Can Bacteria be the Fountain of Youth?

Over the past decade the importance of the bacterial microbiome has become clear with links to gastrointestinal, inflammatory, metabolic and neurological disorders being observed routinely. A new study, published in the journal Current Biology, extends this into longevity. Scientists gathered … Continue reading

Cell-Based Endotoxin Detection

The gold standard for endotoxin detection is the LAL assay. However, due to its enzymatic nature and the dependence on harvesting a wild species, an alternative method could prove to be valuable. Scientists in China and the US recently published … Continue reading

A Review on Endotoxemia

The October issue of the Journal of Leukocyte Biology includes an excellent review article on the issues surrounding endotoxemia and in detecting endotoxin in biological fluids. As is often the topic with this newsletter, the author begins by noting the … Continue reading

Move Over, E. coli?

Escherichia coli was discovered over 130 years ago and has become the dominant model organism for microbiology, genetics, gene function and protein expression analysis and proteomics. In the past few decades it has become a workhorse in producing therapeutic recombinant … Continue reading
