Fig 2. Aerobic gut bacterial numbers (CFU/g) in nurse bees from healthy hives (n = 47) and chalkbrood-infected hives (n = 31).
Bees were collected from around Australia. The difference between the two groups is statistically significant (P < 0.001). Error bars represent the standard error of the mean (SEM) with a 5% least significant difference (LSD) level of 0.716.
