Typhus Typhus is caused by rickettsia , which is transmitted to humans through lice.

So chemists got to work, and they developed a bactericide that became widely used in those systems.

One day, we may be able to design bacteria that can quickly, safely, and effectively clean up oil spills.

If Ouch is right! If you see this, and you're a bacterium, this is like your worst nightmare.

Occurrence Nitrous oxide is emitted by bacteria in soils and oceans, and is thus a part of Earth's atmosphere.

Effects on the environment Untreated organic matter that contains fecal coliform can be harmful to the environment.

So you can take a bacteria that really doesn't make these things at all, and if you could clamp these on it really well you have it taken off the street.

When a part of the human diet, some plant lignans are metabolized by intestinal bacteria to mammalian lignans enterodiol (1) and enterolactone (2).

Thus, there have been instances of some developing countries' consignments of prawns and frozen seafood being rejected by certain developed countries, which insisted on a zero bacteria count instead of a minimum acceptable level, as per international standards.

However, anthrax vegetative bacteria that escape the body via oozing blood or through the opening of the carcass may form hardy spores.

The disease is caused by a bacillus called Myobacterium leprae, first identified in 1873 by G.H. Armauer Hansen.

Most contaminants are coliform bacteria and faecal streptococcus, and among chemical ones, there are ammonia, nitrates, nitrites, rare heavy metals and other toxic agents.

Others have pointed out that, although the team produced a synthetic genome, they put it into a cell from another bacterium, replacing that cell s DNA.

Here, this cloaked, secret agent virus is slipping his DNA into the bacterial cell, but here's the kicker It doesn't do anything harmful not at first.

It takes control of these cells, turns them into virus making factories, and they all burst, a huge, extended bacteria family, all dying with viruses spilling out of their guts, the viruses taking over the bacterium.

But suppose you take some dirt and dig through it and then put it into these spectrometers, because there's bacteria all over the place or you take water anywhere on Earth, because it's teaming with life, and you make the same analysis the spectrum looks completely different.

And my favorite example of that occurred beginning in 1976, when it was discovered that the bacteria causing Legionnaires disease had always been present in natural waters, but it was the precise temperature of the water in heating, ventilating and air conditioning systems that raised the right temperature for the maximum reproduction of Legionella bacillus.
