Viruses vs Bacteria 101: Differences in reproduction. (A Fun/Simple Guide) Inspired by Flu Season.

Reading: Lovesick by Dr. Frank Tallis
Bacteria carry all the "machinery" (cell organelles) needed for their growth and multiplication.
Bacteria usually reproduce asexually. In case of sexual reproduction, certain plasmidsgenetic material can be passed between bacteria. But on the other hand, viruses carry mainly information - for example, DNA /// RNA, packaged in a protein and/or membranous coat.
Viruses harness the host cell's machinery to reproduce. Their legs attach onto the surface of the cell, then the genetic material contained inside the head of the virus is injected into the cell. This genetic material can either use the cell's machinery to produce its own proteins and/or virus bits, or it can be integrated into the cell's DNA/RNA and then translated later. When enough "baby" viruses are produced the cell bursts, releasing the new viral particles. In a sense, viruses are not truly "living," but are essentially information (DNA or RNA) that float around until they encounter a suitable living host.
Viruses are the simplest and tiniest of microbes. -They can be as much as 10,000 x smaller than Bacteria.
Viral Poetry:
When viruses come into contact with the host cells, they trigger the cells to engulf them and connect themselves so they can release their DNA into the cell. Once a host cell, viruses take over its machinery to reproduce. Once this occurs, the Virus then overrides the host cell's normal functions with their own set of instructions which shut down the production of the host's proteins and direct the cell to produce viral proteins to make new virus particles. Some viruses insert their genetic material into the host cell's DNA, where they begin directing the copying of their genes or simply lie asleep for years or a lifetime. Either way, the host cell does all the actual work, the viruses simply provide the instructions.
Some other fun Facts:
[x] Antibiotics can kill bacteria but not viruses.
[x] There are some useful bacteria but all viruses are harmful.
[x] Bacteria (larger) Virus (smaller) :
| Size: | Larger (1000nm) | Smaller (20 - 400nm) |
Summary:
Bacteria (singular: bacterium) are unicellular microorganisms. They are typically a few micrometres long and have many shapes including curved rods, spheres, rods, and spirals.
Viruses (from the Latin noun virus, meaning toxin or poison) is a sub-microscopic particle (ranging in size from 20–300 nm) that can infect the cells of a biological organism.
A bacterium is a microbe (a microscopic single cell organism):
A Bacterium consists of a single cell. Also accurate///detailed: Bacteria are single-celled living prokaryotic organisms.
Prokaryotic: ic = Pertaining to. Pro = “before”, karyon = “nucleus”
Prokaryotes:
Prokaryotes were the first type of cell to evolve, and, still lack a membrane bound nucleus. Their genetic material is naked within the cytoplasm, ribosomes their only type of organelle.
Prokaryotes are most always single-celled, except when they exist in colonies. These ancestral cells, now represented by members of the domains Archaea and Eubacteria, reproduce by means of binary fission, duplicating their genetic material and then essentially splitting to form two daughter cells identical to the parent.

Bizarre Illness Terrifies Sudanese - Nodding Syndrome
Jul. 1st, 2009 | 03:35 pm
Music: Burning sun

The affliction, which has been found in about 300 children so far, baffles experts. The World Health Organization began investigating it about two years ago, around a year after Martha's symptom first appeared.
Peter Spencer, an American neurotoxicologist who has investigated the condition for WHO, encountered another 13-year-old girl with a bizarre variation of the illness.
"I was able to demonstrate with her that she was a regular nodder with local food and by contrast she did not nod when eating a variety of American food — candy bars or whatever. It was absolutely staggering," he said.
As she sits on a sisal mat with her parents under the shade of a tree beside their mud huts, Martha says no treatment has helped her.
One traditional healer claimed that Martha's aunt, who was killed by lightning a few years ago, had bewitched the girl. Following his advice, the family held a ceremony attended by the entire village and sacrificed a sheep.
Recently, another traditional healer told the family to take the girl into the forest to wash the bad spirit away.
"He told us to bring a black goat and a red hen and make a tunnel in a termite hill," Majak said. "She crawled through the hole back and forth three times. Then we had to kill the goat and the hen in sacrifice."

Very interesting links I thought I forgot about. Part one of my bookmark blowout entries. I have a lot of shit saved. I personally love the medical prints, lithographies, visuals the most for personally browsing and especially icons. I'll probably post a lot on that stuff.

Intro - scoteography

Music: Morning
Reading: DNA for beginners illustrated, Israel Rosenfield, Edward Ziff and Borin Van Loon
scoteography ;
The art of writing in the dark (McKean 2003)However fitting, I find this a good starting point. Writing in the dark. The Art of doing this, even. If you take this word literally I'm sure you'll have no use for the term applied to the theme of this journal. My point is not to poeticize here; but inside, an attempt at forming connections. Natural Sciences - Art - Literature - Words & Language, expressive /// expressing that "all 'living' things", these subjects - in the dark. And here we are; a dot on the map: exploring, tinkering, exposing, we're writing in the dark. Oh yes, and the Art of doing so, of course.
Technicalities -
I sometimes get bored with my other journal or maybe it's that my other journal is bored of me for these subjects are something like precious gems and I'm the hungry collector. Finally made the choice to turn my personal bookmarks into public entries. Maybe it'll attract some other med-heads. or maybe IT won't.
Feel free to add this journal if you like what you see. I will try to post often and more creatively when I've got a system going and design fully equipped - right now I'm just tinkering. If you (which is basically asking myself) have any suggestions, links, or any informational thingamabobits, visuals to suggest or share, my window is cracked.
You can find an email on the profile, along with a (very temporary) wikipedia screenshot because I'm not very good with proper introductions and that kind of thing. I'm just playing with design now. It's decent but not right yet. I expect many changes over time, however the content and themes will pretty much stand still. Medical Artwork, the odd and anomalous, the ironic and beautiful, science, nature, words & quotes & more along that faultline.
