AIDS patients have a major problem with infections by viruses and opportunistics pathogens.?

Give three example of these.Explain why an AIDS victim is so vulnerable to these pathogens.

meh, for ten points, why not?

AIDS patients have no immune system. Therefore, it is easier for infections to take hold and wreak havoc on the body. That is the basic gist of why AIDS patients (must we call them victims? let's not) are vulnerable.

Common opportunistic infections include: Pneumocystis carinii pneumonia, chronic Candida albicans infections (yeasts, thrush) and Toxoplasma gondii.

Usually a healthy immune system can suppress proliferation of these organisms. Candida albicans lives on people and keeps a low profile. But without an immune system, the yeasts replicate like crazy causing infection. Likewise, Toxoplasma is a common cat parasite and most people have been exposed to it at some point, but with no immune system, this parasite can grow freely and then infect the brain, causing death. P. carinii is a bacterial pneumonia you only see in people with immune deficiencies. Healthy people can fight the bacteria off, but AIDS patients become infected with it and die of pneumonia.

No thanks...I am not doing your homework for you. Look it up.

AIDS is short for aquired immunity defficienty syndrome. This means that this virus (HIV) get's into yopur blood stream and into your immune system (white cells), hiding from other white cells. This makes your whole immune system vulnerable.. making you more weak, to many diseases... White cells are "hosteges" of this virus, the virus uses all the resources of the cell, (ribosomes, nutrients, mitochondria, etc) to make it's one proyteins and enzymes to be albe to spread this disease... the thing is it is also so hard to treat beacuse, given that the virus is inside your cells, to eliminate it you'll have to kill your own cells, making you weaker and more difficult to fight any other disease in the proces... no or little immune response means that a normal cold can be dangerous....What do you mean with examples?
