Babesia is a protozoan parasite that infects red blood cells and causes babesiosis, a malaria-like disease. It is transmitted through the bite of infected ticks. The document discusses the classification, history, morphology, transmission, lifecycle, diagnosis and treatment, and prevention of Babesia.

4. BabesiaAlso called Nuttallia.
Babesia is a genus of protozoan
apicomplexan piroplasms that infect the blood
and cause a parasitic, hemolytic disease known
as babesiosis
Babesiosis suffer from malaria-like symptoms

7. 1. Classification
Phylum: Apicomplexa
Class: Aconoidasida
Order: Piroplasmida
Family: Babesiidae
Genus: Babesia

8. 2. History
A Romanian scientist who first documented the
disease in 1888, described symptoms of a
severe hemolytic illness seen uniquely in
cattle and sheep which is known as babesiosis
It is serious illness for wild and domestic animals
especially cattle and sheep.

9. In 1957 Americans T Smith and Fred K identified
the parasite as the cause of Texas Cattle Fever
also identified the tick as the agent of
transmission,
1969 the first case of Babesiosis was seen in
humans

10. 3. Morphology
• Babesia enters erythrocytes at the sporozoite
stage. Within the red blood cell, the protozoa
become cyclical and develop into a
trophozoite ring The trophozoites morph into
merozoites,
• Babesia Morphology are just like Plasmodium
just that causes Malaria.

12. 4. Transmission
Vector
1. white-footed mouse
2. Ticks
3. white-tailed deer

13. 4. Transmission
• Babesia is spread through the saliva of a tick
when it bites. Babesia is transmitted after the
bite of ticks. There are many species
of babesia which transmit the disease.
• Ixodidae scapularis is the most common
vector. commonly known as a deer tick, which
cause the Lyme disease

15. 5. Lifecycle
• The infective stage of Babesia in ticks is a
sporozoite. sporozoites in tick
salivary glands are injected into host erythrocytes in
blood and begin the binary fission development
b/w trophozoites and merozoites producing
more trophozoites, some merozoites
produce gametocytes. The tick definitive
host takes up the gametocytes when attached for
a blood meal. The gametes are fertilized in the
gut of the tick and develop into sporozoites in the
salivary glands of the ticks

17. 6. Diagnosis and treatment
Diagnostic Tests
1. Though blood sample testing just like Malaria.
They are similarity to Malaria Plasmodium
falciparum
