Study Notes
Babesiosis
- Babesiosis is a tick-borne disease caused by the intracellular sporozoan parasite Babesia, transmitted through the bite of an infected Ixodes tick.
- The longer the tick attachment, the higher the risk of Babesia infection.
Symptoms
- Hemolytic anemia is a common symptom of Babesiosis, which can lead to jaundice.
- Irregularly cycling fevers and sweating are also common symptoms.
- Patients with sickle cell disease are at higher risk of severe disease.
- Asplenia (absence of the spleen) increases the risk of severe disease.
Diagnosis
- Babesiosis is diagnosed by examining a thick blood smear, which reveals the characteristic Maltese Cross appearance in red blood cells.
Epidemiology
- The North East US is the predominant region for Babesiosis.
- Coinfection with Borrelia (Lyme disease) is possible due to the shared Ixodes vector.
Treatment
- Atovaquone and azithromycin are used to treat Babesiosis.
Parasitology
- Babesia are intracellular sporozoan parasites that infect erythrocytes.
- Infectious pyriform bodies are introduced into the bloodstream, where they infect erythrocytes.
- Trophozoites multiply by binary fission, forming tetrads, and then lyse RBCs, releasing merozoites.
- Advanced cases can lead to hepatomegaly and splenomegaly.
