Table 2. Comparison of community diversity between groups and visits.
| Diversity index | H group |
AV (H) group |
||||
|---|---|---|---|---|---|---|
| Week 0 | Week 2 | Week 4 | Week 0 | Week 2 | Week 4 | |
| Shannon diversity | 1.04 ± 0.73 | 1.03 ± 0.70 | 1.05 ± 0.67a | 1.12 ± 0.63b | 0.60 ± 0.578 | 0.61 ± 0.58c |
| Shannon equitability | 0.29 ± 0.18 | 0.28 ± 0.16 | 0.28 ± 0.16a | 0.36 ± 0.17b | 0.17 ± 0.14 | 0.174 ± 0.14c |
aIn the H group there was no significant difference (p >0.05) in the Shannon diversity and equitability indices for samples collected in weeks 0, 2 and 4.
bThere was no significant difference between AV Group before treatment (week 0) and N Group (weeks 0, 2 and 4) in Shannon diversity index and equitability (p >0.05).
cIn the AV group the Shannon diversity and equitability indices in week 0 (before treatment) were significantly higher than those in weeks 2 and 4 (during and after treatment). There was no significant difference in these indices between week 2 and 4 of the AV group.
