Diet impacts gut bacteria, which in turn influences rates of asthma, allergies, inflammatory bowl disease, and other inflammatory diseases

When children become sick, when rates of disease increase in adults, both apparently without an obvious cause, there is an unfortunate tendency for some to seek to profit at the expense of the suffering by offering up phony theories and bizarre hypotheses to "explain" these impacts. Witness...

Antibiotics and vaccines can act as selection factors for bacteria

As noted in prior posts, almost anything has the potential to act as an evolutionary selection factor. [Yes, Virginia, there really is evolution.] A recent assessment that traces the history of a virulent strain of pneumonia-causing bacteria demonstrates that both antibiotics and vaccines can act as...

Humans can transmit diseases to gorillas

Prior posts have noted and described a number of human diseases that had their origin in animals. Now it appears that some diseases can be transmitted from humans to gorillas. Ecotourism has been seen as a boon for countries with "interesting" biota; it provides funding for protection of...

Can antibiotics interfere with the body's ability to fight viruses? Perhaps so.

Prior posts have noted that abuse and misuse of antibiotics in people and animals has lead to an increase in antibiotic resistant organisms, to the detriment of human health. Prior posts have also noted the importance of bacteria to human health and welfare (and that there are 10 bacteria in the human...

Another reason to control erosion and nutrient runoff -- Cholera

Numerous prior posts have followed the growing understanding of what factors drive the Gulf of Mexico dead zone. It pretty much comes down to nutrient runoff into the Mississippi River and its tributaries (e.g., sewage, feedlots, agricultural fertilizers). Now, another association of such nutrient additions...

Eating yogurt without more does not produce lasting changes in the mix of bacteria in the GI tract

Prior posts have noted the impact of GI bacteria on human health, from their potential to prevent a variety of diseases to perhaps being the cause of other afflictions. In what has been referred to as an elegant study, researchers undertook human and animal studies to ascertain what effect, if any...
