Extended Data Fig. 1: Gross pathology of mammary gland from Cow #6.
From: Dairy cows develop protective immunity against reinfection with bovine H5N1 influenza virus
Cow #6 was euthanized at 4 days post-inoculation which coincided with peak virus shedding in milk. The mammary tissue of the left hindquarter appeared grossly mildly hyperemic when compared to the other quarters (marked by asterisk). Milk in the forequarters had a grossly normal appearance (black arrow) relative to milk in the hindquarters was thick and discolored (white arrow).
