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.
I. INTRODUCTION. The nonmotile coccoid and colonial green algae belong to the division Chlorophyta. The Chlorophyta include a diversity of taxa (morphologically and ecologically), ranging from unicellular and freshwater taxa (e.g., Chlamydomonas; Chap. 6) to multicellular and marine taxa (e.g., Ulva).oil is a common habitat for nonmotile green algae (e.g., Apatococcus, Chlorococcum, Chlorosarcinopsis, and Tetracystis), which are widely distributed in a variety of soil types and microclimates (Starks et al., 1981). Chlorococcum is a common taxon found in soils.
