What are 3 viruses and bacteria that attack the immune system?
Im doing a project in my biology class about viruses and bacteria.
The question is "Describe at least 3 viruses and bacteria that attack the immune system. Also explain how they work, live and survive."
I already have one virus (HIV) but i need 2 more viruses and 3 bacterias that attack immune system. Also can you elaberate on how HIV attacks the Immune System and how it survives?
Thanks for all your help!
Attack is kind of a bad word here!! Viruses "generate" an immune response. 3 such virus ..some common one:1-Herpes, Chicken Pox( varicella zoster virus), Rabies virus( Rabies disease), Measles Virus, Rubella virus.
Bacteria: pneumonia( streptococcus pneumoniae),Salmonella(salmonella species), Gonorrhea( Neisseria gonorrhoeae)..other diseases- syphylis,cholera..you can google these and see the name of the bacteria.
Viruses are parasites and their mode of operation varies. They can survive only when they parasitise another organism, you name the organism and there is a virus that lives on it.They live in our cells, the nucleus, cytoplasm and they live in a varied number of cells. Some specialise in cells of the nervous system, immune system(HIV), etc. Even bacteria have viruses that parasitize them- they are called bacteriophage.
HIV virus is a very special virus , in that it has evolve to live within the very cells that are suppose to be protecting us- The many cells of the immune system- macrophages and Tcells. HIV uses a receptor(CD4) that is present on Thelper cells to invade our body. The problem here is that the Thelper cells are called whenever there is an invasion( a foreign matter /antigen) in our system and are absolutely necessary for us to remain healthy. Once they have been invaded by the virus then they are marked for death. The body begins to remove them in an attempt to get rid of teh virus. Thereby rendering us more vulnerable to other infections- because now our defense is being broken down. Viruses on a hold have been able to manipulate our bodies to their advantage being the true parasites they are. for more information you can go to google really/ any university link, once that end in dot edu should be good. i hope i was helpful i tried my best. Good luck!!

HIV doesnt attack. it’s a process that allows the virus to attack more efficiently
