Same fold in viral shells point to common ancestry
...the phi 29 virus, which attacks the soil bacterium bacillus
subtilis, possesses a protein fold in its capsid similar to the fold found in the HK97 virus, which infects E. coli bacteria. Researchers used a technique called cryoelectron microscopy to determine the three-dimensional structure of phi 29 down to a...

during natural infection in endemic populations in Africa, the impact of progressive HIV-1 infection and its treatment and changes during vaccination with BCG and novel vaccine candidates. The Project Consortium consists of 15 laboratories in Africa...
Dangerous tricksters: Some bacterie use immune cells to reproduce
...hodococcus equi is closely related to the tubercle bacillus
(Mycobacterium tuberculosis). Since macrophages are the main target of Rhodococcus in the horse's lung, a lot of rhodococci are found there during an infection. In the Bonn Institute of Cell Biology Eugenia Fernandez and Marco Polidori in Professor ...
Innovative research set to push boundaries of cancer care
...he only widely used bacterial treatment to date is bacillus
Calmette Gurin (BCG) for superficial bladder cancer. Researchers at the University of Illinois at Chicago, however, have found that an opportunistic bacterium, Pseudomonas aeruginosa, that grows in the soil and marshes but is often found in the lung...

National Institutes of Health funds $13.7 million for Texas tuberculosis study
...rld's population is currently infected with the TB bacillus
and about 1.7 million died of TB in 2004, according to the WHO's latest figures. Sacchettini's research team, which collaborates with 90 laboratories in 15 countries, uses protein crystallography, a method of examining molecules three-dimensionally t...
