Scientists resolve debate over how many bacteria fight off invaders Every inch of our body, inside and out, is oozing with bacteria. In fact, the human body carries 10 times the number of bacterial cells as human cells. Many are our friends, helping us digest food and fight off infections, for instance. But much about these abundant organisms, upon which our life depends, remains mysterious.
Antibiotic resistant typhoid detected in countries around the world There is an urgent need to develop global surveillance against the threat to public health caused by antimicrobial resistant pathogens, which can cause serious and untreatable infections in humans. Typhoid is a key example of this, with multidrug resistant strains of the bacterium Salmonella Typhi becoming common in many developing countries.
Bacteria shown to suppress their antibiotic-resistant cousins Researchers studying a dangerous type of bacteria have discovered that the bacteria have the ability to block both their own growth and the growth of their antibiotic-resistant mutants. The discovery might lead to better ways to fight a class of bacteria that have contributed to a growing public health crisis by becoming increasingly resistant to antibiotic treatments
New test could identify resistant tuberculosis faster The time needed to genetically sequence the bacteria causing tuberculosis (Mtb) from patient samples has been reduced from weeks to days using a new technique. This could help health service providers to better treat disease, control transmission of this infection, and monitor outbreaks.
