0 a type of very small organism that lives in air, earth, water, plants, and animals, often one that causes disease:
Our findings are of special interest because the bacterium we discovered represents a genuine thermophilic species.
Our use of modern soil bacteria as the inoculum might be considered artificial relative to studies on the establishment of the first bacterium.
Figure 4 shows a cartoon of the photosynthetic membrane of a typical purple bacterium.
Finally, during our observations of the seminal receptacle we did not observe any structure in the spermatozoa which could be interpreted as an intracellular bacterium.
The bacterium must therefore traverse this cellular barrier, and this is thought to occur through the endothelial cells rather than around them.
First, the search for a productive strain of bacterium that was capable of generating a large amount of toxin.
However, ruminants appear to be the major reservoir for this bacterium.
In the biological case, when a bacterium is in an environment where it can survive, it may replicate.
