Insects cultivate 'antibiotic-producing bacteria' in their antennae
April 02, 2007Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. This highly specialised interaction between an insect species and bacteria protects the insect's offspring against microorganisms which might infect it during its cocoon stage.
Females of the European Beewolf cultivate the bacteria (a species of the antibiotic-producing genus Streptomyces) in the glands of their antennae and apply them to the brood cell before they lay their eggs. "The larvae take up the bacteria and apply them to the silk threads of their cocoons", says Dr Kaltenpoth (University of Regensburg) who will be presenting his work at the Society for Experimental Biology's Annual Main Meeting in Glasgow on Sunday 1st April.
Experiments have indicated that the streptomycetes bacteria protect the cocoon from fungal infection and significantly enhance the larva's chances of survival during hibernation in the soil, possibly by producing antibiotics. All beewoolf species investigated so far show up positive for the bacteria which indicates it is essential for their survival and could play an important role in other insect species too.

Unrelenting toothache means a visit to the dentist is inevitable, and if the tooth decay is really bad root canal treatment is often the only option.
New insight into predicting cholera epidemics in the Bengal Delta
Cholera, an acute diarrheal disease caused by the bacterium Vibrio cholerae, has reemerged as a global killer. Outbreaks typically occur once a year in Africa and Latin America. But in Bangladesh the epidemics occur twice a year - in the spring and again in the fall.
Study sheds light on evolution of human complexity
A painstaking analysis of thousands of genes and the proteins they encode shows that human beings are biologically complex, at least in part, because of the way humans evolved to cope with redundancies arising from duplicate genes.
There's a speed limit to the pace of evolution, Penn biologists say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits."

USU scientists report major advance in human antibody therapy against deadly Nipah virus
A collaborative research team from the Uniformed Services University of the Health Sciences (USU), Australian Animal Health Laboratory and National Cancer Institute, a component of the National Institutes of Health, reports a major step forward in the development of an effective therapy against two deadly viruses, Nipah virus and the related Hendra virus.
Bacteria 'launch a shield' to resist attack
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system.
An exquisite container
In campy old movies, Lucretia Borgia swans around emptying powder from her ring into wine glasses carelessly left unattended. The poison ring is usually a confection of gold filigree holding a cabochon or faceted gemstone that can be broken to empty the ring's contents. It is invariably enormous - so large it is rather odd nobody seems to notice it.

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. |
