Figure 4.

(A) Fecal IgA content at different time points (T0; T15; T30; T60); each value (mean ± SD) represents the average of the measurements of the three samples collected in three consecutive days for each experimental point: T0, before the administration, T15 and T30, after 15 and 30 days of Lk administration; and T60, 1 month after the last Lk administration. The T60 fecal samples of dog #6 were excluded from the analysis due to antibiotic therapy. (B) IgA fecal content evaluated by the ratio between the quantity at T15, T30, and T60 and the basal (T0) for each dog.
