Gram negative bacteria
South African researchers have expressed concern about the increasing number of bacterial infections that are becoming resistant to the available range of antibiotics.
Contaminated intravenous equipment and poor infection control measures were found to be the source of an outbreak of klebsiella pneumoniae which killed 21 babies in a KwaZulu-Natal hospital.
The bacterium that causes dysentery uses a 'sword and shield' approach to attacks cells while protecting itself from the inflammation it triggers. The findings were published by Nicholas West and colleagues in Science this week.
