The immune and central nervous systems
It affects the heart and all the joints in your body
An Aschoff body is a painless nodule found in rheumatic fever.
it uses bacteria and mouse urine and then spreads to the legs and then body
It does serious damage to the valves in the Heart.
Heart
Rheumatic fever does not affect throat. It does affect heart and joint. This happens probably because the antibodies formed against the beta haemolytic streptococci also attack the heart valves and the joints. Probably they have similarity with the antigen of bacteria.
The difference between rheumatic fever and rheumatoid arthritis is that rheumatic fever affects the kidneys and heart and is typically caused by strep throat. Rheumatoid arthritis is arthritis.
measles-measles mainly affects the skin on your body where a blotchy red rash appears, it also affects your immune system and you get a cough, runny nose and a fever.
protein antibodies produced to defend the body against streptococcus bacteria
Rheumatic fever is actually your body's severe inflammatory reaction. It is first caused by an infection with Streptococcus bacteria. it's kind of a late complication, so that even with treatment with antibiotics, the heart is often damaged, and you may still have joint pains, etc.
Protein antibodies produced to defend the body against streptococcus bacteria
Scarlet fever, or rheumatic fever, is indirectly caused by Strepoccocus bacteria: more accurately, it is a case of hypersensitivity, where the immune system attacks its own body, most likely due to similar antigens.In the case of rheumatic fever, it is attack on the heart. The immune system can successfully fight off Strepoccocus bacteria that cause strep throat. Unfortunately, Strepoccocus is a clever bacterium: its antigens are similar to that of a heart muscle's. After the bacterium has been defeated, the immune system mistakens its heart muscles' antigens for the bacterium's forigen look-alike. The immune system then attacks the heart, causing rheumatic fever.
