When does the shedding of Coryza bacteria typically cease relative to visible recovery?
Answer
Shedding peaks when signs appear and subsides over two to three weeks, overlapping recovery.
The timing of bacterial shedding in Infectious Coryza does not perfectly align with the bird's apparent recovery. The shedding of *A. paragallinarum* tends to peak around the time clinical signs become evident. Following this peak, the amount of shed bacteria gradually decreases over the subsequent two to three weeks. Crucially, this period of active shedding often overlaps with the recovery phase, meaning a bird that looks significantly better or is beginning to return to normal activity may still be actively shedding the pathogen and capable of infecting others until the shedding period is truly complete.
