  1. *The mean score ± SD in the control group was 0.0 ± 0.00 for all tissues.
  2. aP < 0.05 for a comparison of the control group and the infection group.
  3. bP < 0.05 for a comparison of the control group and the re-infection group.
  4. cP < 0.05 for a comparison of the infection group and the re-infection group.
