Fig 3. Aerobic gut bacterial numbers (CFU/g) in nurse bees from healthy hives (n = 10), chalkbrood-infected hives (n = 10), and chalkbrood-infected hives 21 weeks after the disappearance of disease signs (recovered; n = 10).

All bees were collected from a single apiary in New South Wales. The differences between all groups are statistically significant (P < 0.001). Error bars represent the SEM with a 5% least significant difference (LSD) level of 1.095.
