2. What is the related topics?Bacteriology, immunology, cell biology, infectious diseases, pathogenesis, antimicrobial resistance
3. How does Mycobacterium tuberculosis survive inside cells?It stops the cell’s cleaning bag (phagosome) from joining the trash bag (lysosome), so it can stay safe and eat the cell’s fats.
4. Why do some bacteria need to stay inside cells while others can live outside too?Bacteria that are obligate need the cell for food and protection, while facultative ones can live both inside and outside, like Salmonella or E. coli.
