Data are expressed as the means ± SE, n = 10 and transplantation groups, n = 11. Data that were less than 0.1% in both the control and transplantation groups were omitted from the table. Data were analyzed using the Student’s t-test or Welch’s test. Transplantation of the inoculum was performed on days 3 and 4. C, control group; T, transplantation group. *, ** Mean values were significantly different from those of the control group (p < 0.05, p < 0.01). † Mean values tended to be higher than those of the control group (p = 0.0777). ‡ Correlations were determined by Spearman’s rank correlation coefficient.
