In brief: Hours to weeks
Most bacteria take hours to days to appear in culture.
Bugs that cause TB and related infections can take up to 2 months. Some bugs can't be grown in culture at all. Its important to remember that not every bug in a culture is an infection and a negative culture cannot exclude some infections. Cultures are like every other test, with false positive and negatives that your doctor has to interpret.
