maltophilia in products of this type, especially if subject to temperature abuse, are unknown, but in the domestic setting, numbers of the bacterium
may increase before use.
Ironically, the enzyme is made by a virus: a smaller, simpler microbe than a bacterium
. This particular type of Virus--known as a bacteriophage or simply "phage"--evolved to invade only anthrax bacteria.
Alterations in antibiotic target sites can occur through spontaneous mutation of a bacterium
's own genetic material, acquisition of DNA from another bacterium
, and acquisition of DNA fragments, known as plasmids, which can travel from one type of bacterium
They are continuing to describe not only how the microbe synthesizes that reinforced cell wall, but also other ways in which the bacterium
fends off drugs.
Adhesion to positively charged bacterium
Stenotrophomonas (Xanthomonas) maltophilia 70401 to glass and Teflon.
coli O157:H7 is a vicious new strain of bacterium
that causes bloody diarrhea, cramps, dehydration, and, in severe cases, kidney failure, blindness, and death.
To investigate how one human-gut bacterium
interacts with the most common human-gut archaeon, microbiologists Jeffrey I.
But with each duplication, there's a chance of a mutation--a slight copying error that will give one daughter bacterium
a new trait.
Some manufacturers, including Dannon and Yoplait--the two largest--are now adding another bacterium
, Lactobacillus acidophilus, to their yogurts.
Normally, an encounter with a pathogenic virus or bacterium
prompts these components, helper T cells, to ooze proteins that alert other immune cells to work together to vanquish the intruders.
Chances are that sometime during the past 24 months, your body was invaded by a bacterium
or virus that had taken up residence in a food you ate.
The scientists are working with a strain of the bacterium
that doesn't make people sick.
A bacterial species that typically colonizes people's noses may win out over another bacterium
by tattling to the human immune system, a new study suggests.
John Blanchard of the Albert Einstein College of Medicine in New York says that such catalogs have guided his lab in making synthetic compounds that target a bacterium
's Achilles' heel--any of the proteins or other compounds required for its survival.
He says, however, that he's skeptical that evolution led the bacterium
to tug on cell membranes in just the right way to lengthen the cells' survival.
