Vaccine could cut complications after surgery
April 03, 2002A vaccine has been developed, which could prevent inflammation and illness caused by certain bacterial infections following major surgery, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.
Dr Elliott Bennett-Guerrero, Chief of Cardiac Anesthesia at Columbia University College of Physicians & Surgeons, New York, USA says, "Severe inflammation caused by bacterial toxins is becoming recognised as an important cause of illness following major surgical operations. We have developed a vaccine to toxins that are found in the Gram-negative group of bacteria, which includes E. coli 0157 and Klebseilla pneumoniae."
Toxins, known as endotoxins, are made up of fats found on the cell surface of Gram-negative bacteria. When infections are treated with antibiotics these bacteria burst into pieces, which increases the amount of endotoxin released into the bloodstream. This can cause severe inflammation throughout the body and not just at the site of surgery.
Dr Bennett-Guerrero says, "There are no effective treatments for inflammation induced illness. Vaccines have not previously been used to prevent Gram-negative bacteria infections in hospitalised patients because they themselves can produce inflammation. Our vaccine contains complete endotoxins from several species, which are incorporated into a liposome to avoid toxicity."
"Infections following major surgery now affect over 1 in 5 patients (22%). These can cause a great deal of suffering and increase health care costs. Our vaccine is non-toxic to animals, does not cause side effects such as fever and flu-like symptoms, and should protect against a broad range of species," says Dr Bennett-Guerrero.

Census of Marine Life scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight - creatures that somehow manage a living in a frigid black world down to 5,000 meters (~3 miles) below the ocean waves.
Surface bacteria maintain skin's healthy balance
On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable. Research at the University of California, San Diego School of Medicine now shows that the normal bacteria living on the skin surface trigger a pathway that prevents excessive inflammation after injury.

A protein found in the saliva of ticks helps protect mice from developing Lyme disease, Yale researchers have discovered. The findings, published in the November 19 issue of Cell Host & Microbe, may spur development of a new vaccine against infection from Lyme disease, which is spread through tick bites.

Good Germs, Bad Germs: Health and Survival in a Bacterial World by Jessica Snyder Sachs (Author) Making Peace with Microbes Public sanitation and antibiotic drugs have brought about historic increases in the human life span; they have also unintentionally produced new health crises by disrupting the intimate, age-old balance between humans and the microorganisms that inhabit our bodies and our environment. As a result, antibiotic resistance now ranks among the gravest medical problems of modern times. Good Germs, Bad Germs addresses not only this issue but also what has become known as the “hygiene hypothesis”— an argument that links the over-sanitation of modern life to now-epidemic increases in immune and other disorders. In telling the story of what went terribly wrong in our war on germs, Jessica Snyder Sachs explores our emerging understanding of the symbiotic... |

60 Minutes - Superbug (November 11, 2007) Airdate 11/11/07 MRSA is a superbug, a staff infection that has moved out of hospitals and nursing homes and is now infecting healthy people, sometimes killing them. That's because once the MRSA infection gets into the blood stream, it is largely resistant to antibiotics. For now, the best medicine is prevention. What does this mean? Scrubbing down school desks? Hosing down team locker rooms? Sending infected kids home? Lesley Stahl reports. This product is manufactured on demand using DVD-R recordable media. Amazon.com's standard return policy will apply. |
