Discussion Overview

The discussion revolves around the mechanisms of viral infections and the differences between viruses and bacteria. Participants explore the biological processes involved when viruses infect cells, the body's immune response, and the effectiveness of antibiotics against bacteria. The conversation touches on concepts of life and the complexity of microorganisms.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant inquires about the process of viral infection, suggesting that viruses invade cells and utilize their resources, leading to symptoms like fever and a runny nose.
  • Another participant explains that viruses hijack cellular machinery to replicate, triggering an immune response characterized by increased histamines.
  • There is a discussion about antibiotics, with one participant stating that they target bacteria by disrupting their cellular functions, while noting that antibiotics do not affect viruses.
  • Some participants express confusion about the nature of viruses and bacteria, questioning whether they are similar and discussing the classification of viruses as non-living entities.
  • Concerns are raised about the location of viral attacks in the body and the implications for symptoms like colored mucus, with one participant asserting that colored mucus is associated with bacterial infections rather than viral ones.
  • Another participant comments on the complexity of bacteria, suggesting that while they are simple compared to humans, their evolutionary success makes them difficult to eradicate.

Areas of Agreement / Disagreement

Participants express differing views on the nature of viruses and bacteria, their mechanisms of infection, and the effectiveness of antibiotics. There is no consensus on several points, including the classification of viruses and the relationship between viral and bacterial infections.

Contextual Notes

Some statements reflect assumptions about the definitions of life and the mechanisms of infection that may not be universally accepted. The discussion includes unresolved questions about the nature of symptoms and the effectiveness of treatments.

Who May Find This Useful

This discussion may be of interest to individuals exploring microbiology, immunology, or those seeking to understand the differences between viral and bacterial infections.

I am new at this but i want to make sure i know what i am talking about
I have researched this but i haven't gotten a straight answer

1. When you get sick(common cold/virus) what happens?
Does virus go into each cell and take its nutrients.
Then after that does it keep on spreading and then your body tries to kill it and then you get fever and runny stuffy nose.
2. When you take antibiotics how does it kill bacteria?

and are there different types of bacteria so wouldn't they be the same as viruses

Also i remember long ago i heard one of them was living is that true or not.

1] Virii, because they are bits of DNA, are able to sneak past cells defenses and enter the cell. There, they hijack the cell's machinery and force the cell to start reproducing the virus' DNA. When your body begins sensing these foreign bodies, the defense system is activated - the one we notice most is a big increase in histamines, which pump fluids into your tissues and mucous membranes. This is designed to (belatedly) trap more irritants entering the body.

2] Antibiotics are carefully chosen poisons that target bacteria. They interfere with the bacterium's ability to work, such as constructing its cell wall. This is also why antibiotics don't work on virii - virii are not working machinery.


There are as many kinds of virus as there are bacteria.

Virii are on the verge of life. Many consider them non-life. They are simply bits of DNA. They cannot work without hijacking a living cell.

so if well where do these virii attack
because if they attack in the lower part of your body then when you sneeze would you still get colored mucus

ok and if i get this straight bacteria is a very simple machine
if they are so simple can't humans create something to stop them for good

I may be mistaken but catching a virus does not produce coloured mucous at all. The byproduct of bactgerial infection is the carcasses of bacteria, whose byprodiucts are poisons and have (colour and taste). The offal of a virus is your own cells.

Do not confuse simple with easy. Humans may be the most complex critters on the planet, but bacteria are by far the most successful - they've done quite nicely for 2 billion years.
 
(1) The virus infects a cell, tricks the cell into making more copies of that virus until the cell ruptures and sends those new virii out to infect other cells. Fevers, runny noses, etc. are some of our bodies attempts to get rid of the virus. Of course, some types of virus use runny noses as a way to spread themselves to new hosts.

(2) There are countless types of virii and bacteria. A virus is a bit of DNA or RNA with a protein coating. So they are often thought of as non-living. A bacterium is an independent living cell (single celled organism). A cell is not exactly a simple machine. That aside, bacteria are hard to get rid of because they reproduce extremely quickly and they also evolve quickly. New strains appear and existing ones evolve defenses to attacks on them (which is why antibiotics can become less effective over time).
