Research Abstract

Hemoplasma is a prokaryote that parasites on mammalian erythrocytes and causes a hemolytic anemia in the infected animals. However, its prevalence in the Japanese cattle has remained unknown. Therefore, hemoplasma infection in cattle was examined in this study. Here we demonstrated a wide prevalence of hemoplasma infection among cattle population in Japan.
