Diseases of the White Blood Cells. 1  Neutropenia (pronounced: new-truh-PEE-nee-uh) occurs when there aren't enough of a certain type of white blood cell to protect the body against bacterial infections. 2  Human immunodeficiency virus (HIV) attacks certain types of white blood cells (lymphocytes) that work to fight infection.
Too many white blood cells (a high white blood cell count) can indicate the presence of leukemia, certain infections, or conditions such as measles or whooping cough. Rarely, a bone marrow disease or autoimmune condition (when your body attacks its own cells) can lead to the production of too many white blood cells.lood cell disorders affect your red and white blood cells and smaller circulating cells called platelets. All three cell types form in the bone marrow, which is the soft tissue inside your bones. Red blood cells transport oxygen to your bodyâs organs and tissues. White blood cells help your body fight infections.
