Scientist deciphers language bacterial cells use to 'talk' to each other - also discovers how to quell their conversation

Understanding the way bacterial cells "talk" to each other could lead to more effective methods for fighting the often persistent and serious infections caused by the biofilms they form, says a Texas A&M University professor of chemical engineering who not only has deciphered their language but also discovered how to quell their conversation.

Mycobacterium tuberculosis can grow in surface-level bacteria clusters known as biofilms

University of Pittsburgh-led researchers discovered that the primary bacteria behind tuberculosis can grow on surfaces and that drug-tolerant strains flourish in these bacterial communities, the research team recently reported in Molecular Microbiology.

Bacterial slime helps cause Leptospirosis

Leptospirosis is a serious but neglected emerging disease that infects humans through contaminated water. Now research published in the May issue of the journal Microbiology shows for the first time how bacteria that cause the disease survive in the environment.

Superbug genome sequenced

The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. The research was carried out by scientists at the Wellcome Trust Sanger Institute near Cambridge and the University of Bristol.

Turning on cell-cell communication wipes out staph biofilms

University of Iowa researchers have succeeded in wiping out established biofilms of Staphylococcus aureus (staph) by hijacking one of the bacteria's own regulatory systems.

Bacteria that cause urinary tract infections invade bladder cells

Scientists at Washington University School of Medicine in St. Louis have found definitive proof that some of the bacteria that plague women with urinary tract infections (UTIs) are entrenched inside human bladder cells.

New understanding of how bacteria survive in hostile environments

Using an innovative device with microscopic chambers, researchers from four institutions, including Johns Hopkins, have gleaned important new information about how bacteria survive in hostile environments by forming antibiotic-resistant communities called biofilms.

Beneficial bacteria in the appendix aid digestion after infection

Long denigrated as vestigial or useless, the appendix now appears to have a reason to be – as a “safe house” for the beneficial bacteria living in the human gut.

Space flight makes bacteria more infectious

Space flight has been shown to have a profound impact on human physiology as the body adapts to zero gravity environments.

Bacteria - you can live without 'em, but it won't do you any good!

The finding challenges the conventional wisdom that even harmless bacteria – and the immune response they provoke – suck up the energy of the host organism and hasten its death.

Bacterial biofilms

In one of the first potential applications of synthetic biology, an emerging field that aims to design and build useful biomolecular systems, researchers from MIT and Boston University are engineering viruses to attack and destroy the surface biofilms that harbor harmful bacteria in the body and on industrial and medical devices.
