Graft-versus-host disease (GVHD) is a common side effect of an allogeneic bone marrow transplant. An allogeneic transplant uses blood cells from a family member, unrelated donor or cord blood unit.
Nearly all vertebrate animals host one or more species of the protozoan parasites that produce the infection referred to as coccidiiasis or coccidiosis. Thousands of coccidian species of herbivorous, omnivorous, and carnivorous animals have been described, and many more exist that remain unnamed.
Depending on the sort, cocci bacteria group themselves in a range of ways, such as in pairs, long lines or tight clusters. Examples include Staphylococci (which cause a host of infections including boils) and Gonococci (which cause the sexually transmissible infection gonorrhoea).
