立克次氏体lìkècìshìtǐ介于细菌和病毒之间的微生物,比细菌小,在普通显微镜下看得见。种类很多,多以虱、蚤、壁虱等节肢动物为传播媒介。只有少数能引起人类疾病,如斑疹伤寒、恙虫病等。由美国病理学家立克次(Howard Taylor Ricketts)发现而得名。{rickettsia; any of several families of gram-negative bacteria, observable under microscopes, that are the causative agents of certain diseases, such as typhus and Rocky Mountain spotted fever. They are transmitted to animals and humans by the bite of certain arthropods like lice, fleas, ticks, etc., in whose bodies they live as parasites. It was discovered by Howard Taylor Ricketts, an American pathologist, hence its name.} |
