(Society for General Microbiology) Scientists have uncovered a new target for the potential treatment of TB, finally resolving a long-running debate about how the bacterial cell wall is built. The research, published in the July issue of Microbiology reveals several molecules that could be developed into drugs to treat tuberculosis. Multi drug-resistant strains of Mycobacterium tuberculosis, the bacterium that causes TB, sparked concern but the recent emergence of extensively drug-resistant strains means the search for new treatments is imperative.

(Society for General Microbiology) Bacteria that cause pneumonic plague can evade our first-line defences, making it difficult for the body to fight infection. In fact, a signature of the plague is the lack of an inflammatory response. Now, scientists have discovered a way to protect against death following infection with plague bacteria, by using molecules that can mimic the pathogens. According to research published in the July issue of Microbiology, these molecules make antibiotics more effective and can even be used to protect against other diseases.

A new strain of West Nile virus is spreading better and earlier across the United States, and may thrive in hot American summers, researchers said on Thursday.
