Babesia is a protozoan parasitic in red blood cells. Babesia canis can be divided into Babesia canis and Babesia gibseri.

Blood routine severe anemia, RBC=1.08, HGB=26, HCT=0.091, extreme anemia.

Blood smear showing red blood cells with parasites

Nucleated erythrocytes and numerous erythrocytes with parasites

Massive reticulocytes seen in blood smear

IV. Treatment:

Analysis of a case of Babesia canis

Six, extended reading:

The life cycle of Babesia must be completed by two hosts, and the result of the current study is that the tick is the only known terminal host.

1. Schizogene: Babesia enters the body with the saliva of the tick, then parasitizes in the red blood cells, and reproduces in the red blood cells.

2. Gametogenesis: At this stage, sexual reproduction is carried out. Babesia enters the intestine of the tick with the bite of the tick, most of them die, and a small part develops into a radiator (spindle-shaped with flagella protrusions).

3. Sporogenesis: The zygote enters the tick's organ after repeated division and then enters the oocyte of the female tick. After the progeny tick matures and feeds, it enters the salivary gland, and sporulation occurs in the salivary gland.

From the life history of Babesia, we know that it has a great relationship with ticks, so the clinical incidence basically has a history of tick infection.

The incubation period for the disease is 10 to 21 days after exposure to ticks.

The treatment is divided into the cause and the symptomatic treatment. For the treatment of the cause, it is particularly important to correct the symptoms of anemia symptomatically. When the HCT drops to 15% or even lower, blood transfusion should be considered.
