Shannon-Weaver bacterial diversity index across the 3 sampling periods for the 5 individual dogs. A strong individual response in bacterial diversity to tylosin treatment was observed in all dogs. (day 0 = baseline; day 14 = after 14 days of tylosin administration; day 28 = 2 weeks after cessation of tylosin therapy).
