Counting semi-viable bacteria in cheese
The Wageningen researcher Christine Bunthof has developed a direct method for counting bacteria in dairy products. The method not only distinguishes viable and non-viable bacteria but also semi-viable bacteria. These are too weak to divide, but still exhibit activity. The semi-viable bacteria play an important role in cheese ripening and therefore... view more... (2002-05-23)

Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria 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. view more (2007-04-02)

A chunky metabolism
Many bacteria break their metabolic processes into chunks. That may be logically tidy, but it's often metabolically inefficient. Researchers have now figured out the factors that tend to make bacteria more modular. view more (2008-05-30)

Dust storms may carry bacteria to Japan from China
Bacteria found in soil around Tokyo are not indigenous to the area. A study published in the open access journal Saline Systems reveals a large proportion of salt-loving bacteria in non-saline soil around Tokyo. The researchers suggest that dust storms may have carried the bacteria from their natural habitats in China. view more (2005-10-20)

Guidelines needed to prevent spread of infection in European hospitals
National and European guidelines to control the spread of vancomycin resistant enterococci should be drawn up before these bacteria become endemic in European hospitals, argue researchers in this week's BMJ.

Powerful mold-inhibiting bacteria patented
Bacteria that produce lactic acid have been used for thousands of years to preserve food.

Finely tuned WspRs help bacteria beat body by building biofilm
