An important mechanism for the spread of bacterial resistance to antibiotics is identified

The abuse of antibiotics is commonly (and rightly) associated with the development of bacterial resistance to antibiotics. It is a well recognized principle that underlies attempts to limit antibiotic use to only the most necessary conditions, and to eliminate the prophylactic use of antibiotics in animal...

Amphibians face threats from chemicals across the landscape

Numerous prior posts have noted various theories and evidence for the reduction in number of frogs found in various environments. Taking a step back from focusing on agricultural lands and practices, some researchers are surveying the presence of frogs, including intersex frogs (those with both male...

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...

Some bacteria found on grocery store meat are resistant to antibiotics, often many antibiotics

Prior posts have noted the unfortunate tendency in much of the world, including the U.S., to over prescribed antibiotics (even for conditions in which antibiotics are of no use whatsoever [e.g., viral infections]), resulting in disease-causing organisms that are resistant to many (if not almost all)...

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...

Seaweed and licorice may help improve the immune system of swine, decreasing the need for antibiotics

As noted in prior posts, antibiotics are used not only to treat disease in animals, but also to prevent disease and to stimulate growth. Unfortunately, but not surprisingly, the use of antibiotics in animal husbandry has lead to the rapid development of bacteria that are resistant to such antibiotics...
