Shigella spp. are predominantly connected to humans and are rarely isolated from other animals, with the exception of primates.
Dehydrated culture media for cultivating Shigella come in granules that dissolve in water. Granulation of the media ensures homogenous distribution, which avoids clumping even in warm and humid conditions.
