Careful examination of multiple smears may be necessary, since Babesia may infect less than 1% of circulating red blood cells, thus be easily overlooked. [14] Serologic testing for antibodies against Babesia (both IgG and IgM) can detect low-level infection in cases with high clinical suspicion, but negative blood film examinations. Serology is ...
Babesia, [3] [4] also called Nuttallia, [5] is an apicomplexan parasite that infects red blood cells and is transmitted by ticks. Originally discovered by Romanian bacteriologist Victor Babeș in 1888; over 100 species of Babesia have since been identified.
Plasmodium ovale microgametocyte in Giemsa-stained thin blood film, with annotated Schüffner's dots and hemozoin pigment Trophozoites of P. ovale in thin blood smears. Schüffner's dots can be seen. Schüffner's dots can be seen.
Microscopic examination of fresh anticoagulated blood, or its buffy coat, for motile parasites; or by preparation of thin and thick blood smears stained with Giemsa.

Blood smears showing various developmental stages of the malaria parasite Plasmodium falciparum, stained with Wright stain and Giemsa stain. The preferred and most reliable diagnosis of malaria is microscopic examination of blood smears, because each of the four major parasite species has distinguishing characteristics.
Babesia canis is a parasite that infects red blood cells and can lead to anemia. [1] This is a species that falls under the overarching genus Babesia . It is transmitted by the brown dog tick ( Rhipicephalus sanguineus ) and is one of the most common piroplasm infections. [ 2 ]
Giemsa's solution is a mixture of methylene blue, eosin, and Azure B. The stain is usually prepared from commercially available Giemsa powder. A thin film of the specimen on a microscope slide is fixed in pure methanol for 30 seconds, by immersing it or by putting a few drops of methanol on the slide. The slide is immersed in a freshly prepared ...
