Eosinophil Polymorphonuclear Leukocytes in TB: What We Know so Far

Knowledge on the cellular immune responses to infection with Mycobacterium tuberculosis has improved drastically in recent years. Though eosinophils and hypereosinophilia are linked with the disease process of tuberculosis, there is paucity of information to prove the actual role played by these polymorphonuclear leukocytes. The aim of this review is to provide an overview of the existing literature on what is known so far about eosinophils and tuberculosis.
