Under a magnification of 970x, this Gram-stain photomicrograph of a bovine (cow) tongue tissue specimen revealed the presence of an actinobacillosis granule, which highlights the granule’s “clubbing” histomorphology, in a case of actinobacillosis, also referred to as "wooden tongue" disease.
Additional Information:
Actinobacillosis is caused by species of Gram-negative coccobacilli that are members of the genus, Actinobacillus. There are four members of this genus that have been linked to animal diseases. Only rarely are human beings infected.
