Last year I read a course in biology. During that course I learnt that Protozoa like Lamblia intestinalis or Entamoeba hystolitica form cysts in unfavourable conditions.
This year I read a course in microbiology. I learnt that bacteria like Clostridium perfringens or Bacillus anthracis form spores in unfavourable conditions. So far so good. But then I learnt that prokaryotic Borrelia burgdorferi can form a cyst, not a spore.
Firstly, I would highly appreciate any comments that would cast some light on these terms.
Secondly, I would also like to know if the spore inside, say, B.anthracis is the same organism as B.anthracis that produced the spore. Does a spore and the bacteria that produced it have the same DNA sequence? In other words, if I were a sporeforming bacteria, would my spore be myself, my bodypart or my child?
