Here are some infectious diseases caused by microorganisms in the cardiovascular and lymphatic systems:
Endocarditis is an infection of the inner lining of your heart (endocardium). It typically occurs when bacteria or other germs from another part of your body, such as your mouth, spread through your bloodstream and attach to damaged areas in your heart. Left untreated, endocarditis can damage or destroy your heart valves and can lead to life-threatening complications. Treatments for endocarditis include antibiotics and, in severe cases, surgery.
Plague is an infection caused by the bacterium Yersinia pestis. The bacteria are found mainly in rats and in the fleas that feed on them. People and other animals can get plague from rat or flea bites. In the past, plague destroyed entire civilizations. Today plague is uncommon, due to better living conditions and antibiotics.
Septicemia is a serious, life-threatening infection that gets worse very quickly. It can arise from infections throughout the body, including infections in the lungs, abdomen, and urinary tract. It may come before or at the same time as infections of the:
Infectious mononucleosis, "mono," "kissing disease," and glandular fever are all terms popularly used for the very common infection caused by the Epstein-Barr virus (EBV). The characteristic symptoms of infection with EBV include fever, fatigue, malaise, and sore throat. The designation "mononucleosis" refers to an increase in a particular type of mononuclear white blood cells (lymphocytes) in the bloodstream relative to the other white blood cells as a result of the EBV infection. Scientifically, EBV is classified as a member of the herpesvirus family.
Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells.
Tularemia is an infection common in wild rodents that is passed to humans through contact with infected animal tissues or by ticks, biting flies, and mosquitoes.
Anthrax is a disease caused by Bacillus anthracis, a germ that lives in soil. Many people know about it from the 2001 bioterror attacks. In the attacks, someone purposely spread anthrax through the U.S. mail. This killed five people and made 22 sick. It is rare. It affects animals such as cattle, sheep, and goats more often than people. People can get anthrax from contact with infected animals, wood, meat, or hides. It can cause three forms of disease in people. They are
Lyme disease is the most common tick-borne illness in North America and Europe. Lyme disease is caused by the bacterium Borrelia burgdorferi. Deer ticks, which feed on the blood of animals and humans, can harbor the bacteria and spread it when feeding.
Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. There are different types of leukemia, including

- Cutaneous, which affects the skin. People with cuts or open sores can get it if they touch the bacteria.
- Inhalation, which affects the lungs. You can get this if you breathe in spores of the bacteria.
- Gastrointestinal, which affects the digestive system. You can get it by eating infected meat.
