Our immune system is smart.. but are bacteria smarter? Discuss one strategy our immune system (innate or adaptive) uses to kill bacteria and how the bacteria avoid that specific type of killing. For Example: Our innate immune system uses phagocytic cells, such as macrophages, to ingest bacteria and deliver them to the lysosome where the digestive enzymes will digest the bacteria and eliminate it. Some bacteria, such as H. pylori (the causative agent of stomach ulcers) can survive inside the phagosome inside the macrophage by preventing the lysosome from fusing with the phagosome, thereby avoiding the cell's digestive enzymes and death.Explanation / Answer
Ans- there are various pathogens which survive by avoiding immunity system responses.
One strategy of immunity system is to determine whether the cell is self or foreign body. Some pathogens avoid this by producing a shell or some other protective layer that immunity system fail to recognise it as foreign body.
Example- Stayphlococcus aureus produce a membrane bound coagulase or coagulation factor which make a fibrin clot over the pathogen, one other pathogen Treponema pallium cover itself by fibrinonectin. By this the pathogens are not recognized and so they survive.
