Question

how do microoranisms cause diseases

Answer 1

They infected our body, grow, reproduce and produced toxin or killed our body cells. Once bacteria infected our body, divides in to many and make poisonous substances called toxins. These toxins can damage our cells and produce disease symptoms like high temperature, headaches and rashes on our body.


Similarly viruses also, they take over the genetic material of our cells to make copies of the virus until eventually the cell of our body bursts and releasing many more viruses to infect other cells.
