What happens when bacteria injures host cells?

pstsdyyiv nsvteria that depend on eukaryotic host cells are

There are many forms of parasitic bacteria. The parasitic bacterium that depends on eukaryotic host cells are of the Rickettsia family.

Host cells of viruses include human and other animals, and plants and fungi. Also bacteria and protozoa and algae are host cells of viruses.

Antibodies protect potential host cells. They act against bacteria and viruses.

Host cells release interferons. They are made and released by the host cells because of the presence of different pathogens and bacteria.

targeting structures found only in bacterial cells and not the host cells

Only Bacteria can reproduce outside of a host.. Bacteria are made of cells

Pathogenic bacteria gets inside a host organism & take nutrients from an) organism's cells

Viruses need host cells to replicate and this cannot be done by growing them like bacteria cells are grown.

No. Viruses are noncellular, nonliving parasites that reproduce with host cells while bacteria are unicellular auto or heterotrophs. Also, bacteria are prokaryotic.

You can break the word into: Bacterio+Phagein Bacterio=Bacteria Phagein(greek)=to eat Bacteriophages are viruses that consume bacteria. ie. Their host cells are bacteria.

It depends on how it happened, but most likely the host

The genetic material of the bacteriophage can be passed on to future generations of host cells. Causes resistance on bacteria. Causes the bacteria to evolve.

Symbiotic is when a bacteria does not harm it's host.

Pathogenic bacteria enter host cells basically for "food and shelter", and to hide from the host's immune system. Under normal circumstances, the phagocytic cells of the immune system engulf the bacteria and/or tag them for destruction by other means. This keeps the bacteria away from other cells. Studies indicate however, that pathogenic bacteria enter non-phagocytic cells via receptor-mediated endocytosis. The bacterium has a surface protein that a protein on the host cell recognizes. The cell is then fooled into believeing that the bacterial protein is one that needs to be destroyed or recycled. Since the cell's protein destruction machinery is inside the cell, it brings the bacterium into the cell via endocytosis. And the rest is history!

It kills the host bacteria. I don't believe it occurs in eukaryotic cells.

When a bacteriophage infects a bacteria it enters either the lyctic or lysogenic cycle. the lyctic is the stages of: injection, reproduction, host destruction. The lysogenic cycle is when the virus' RNA mixes with the host cell's.

Bacteria: Single-celled Can exist outside of a host Virus: Not a cell Cannot exist outside of a host for long

Only bacteria can reproduce outside a host +bacteria are not dependent on a host. -Apex

It depends on the pathogen. If it is a virus, the virus will replicate (reproduce its DNA) inside the cell (known as a host cell). The virus clones will then leave the cell and in doing so, cause the cell to die. When this happens many many times, lot of the cells of a tissue die and the tissue itself will start to fail. If it is a bacteria, the bacteria release toxins (endotoxins) which kill the cells directly (from outside).

Primordial bacteria have no organelles. They represent the stage of evolution before organelles were acquired. Organelles (probably) began as infectious bacteria invading ameoba-like cells. If the host didn't kill them off and they didn't kill the host then the bacteria become a sort of parasitic organelle. These can be removed without too much harm to the host. In fact the host would probably benefit by their removal. If the parasitic bacteria them started to provide some service to the host cell then the host benefits from their presence. If the service they provide duplicates some basic process of the host then the host will 'forget' how to do the service itself and rely solely on its (now) symbiotic organelles. This is a very common facet of living things: if you don't use a certain ability then you lose it. Removal of the organelles at this stage would be fatal to the host.

when the bacteria enters the host it finds a target cell... it will then attach to the target cell and inject its DNA into the cell destroying the cells actual DNA.... so when the cell makes copies of what it thinks is its DNA it is really producing more bacterial DNA and it will destroy more cells until antibiotics are ingested

Viruses replicate inside body cells, using the host cell to do the work and provide the materials for reproduction. Bacteria reproduce outside body cells and, since, unlike viruses, they are living organisms, bacteria are able to do the work and production of new bacteria without a need for a host. A description of the 'Lytic Cycle', the process that some types of viruses follow in reproduction, is given in the related questions below for more detail of the process of reproduction of some viruses inside body cells.

Chlamydia is a prokaryote or bacteria. Bacteria are living organisms, capable of their own metabolism and reproduction, even though they may infect host cells. Viruses are not alive. They are chemical constructs that require a host cell for metabolism and reproduction. Viruses have many of the same processes found in living cells, but they lack key metabolism and biochemistry that prevents them from functioning outside of a host cell.

No, the bird is not taking anything from the tree. A parasite takes something from its host, usually in a way that injures the host while giving nothing back to the host.
