These days, fecal transplantation is no joke

Fecal transplants are increasingly being used as the treatment of last resort for certain infections in the human gut and have had remarkable success treating the nursing home and hospital-acquired scourge, Clostridium difficile colitis, an infectious diarrhea that often follows antibiotic treatment. There is also preliminary evidence that the transplantation of stool from healthy individuals can be effective in treating multiple sclerosis and Crohn’s disease.

When mitochondrial genes act up

Mitochondrial disorders are a chameleon-like set of diseases that take many different forms and vary widely from individual to individual.

Mitochondria are special organelles found in cells that produce most of the chemical energy that powers cell operations. Mitochondrial dysfunction has been associated with a wide variety of illnesses, including autism, Alzheimer’s disease, schizophrenia, dementia, Parkinson’s disease, epilepsy, stroke, cancer, chronic fatigue syndrome and cardiovascular disease.

Seth Bordenstein and colleagues discuss Wolbachia-mosquito control in Science

Applied strategies are underway at sites across the world in which mosquitoes infected with the bacteria Wolbachia are released to curb the spread of mosquito-borne dengue virus, Zika virus, and other human infectious diseases. Bordenstein joins colleagues in a recent series of Letters in the journal Science to discuss the risks, or lack thereof, potentially associated with these Wolbachia-mosquito releases.
