The methanolic stock solution is stable and also serves the purpose of directly fixing the smear eliminating a prefixing step. If a working solution is made by dilution with an aqueous buffer, the resulting mixture is very unstable and cannot be used for long. Leishman stain is named after its inventor, the Scottish pathologist William Boog ...
Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. [2] The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria. P. falciparum is therefore regarded as the deadliest ...
Plasmodium malariae and P. knowlesi (which is the most common cause of malaria in Southeast Asia) look very similar under the microscope. However, P. knowlesi parasitemia increases very fast and causes more severe disease than P. malariae , so it is important to identify and treat infections quickly.
Plasmodium is a eukaryote but with unusual features. The genus Plasmodium consists of all eukaryotes in the phylum Apicomplexa that both undergo the asexual replication process of merogony inside host red blood cells and produce the crystalline pigment hemozoin as a byproduct of digesting host hemoglobin.

Ring-forms and gametocytes of Plasmodium falciparum in human blood. Due to the non-specific nature of malaria symptoms, diagnosis is typically suspected based on symptoms and travel history, then confirmed with a laboratory test to detect the presence of the parasite in the blood (parasitological test).
Giemsa stained Trypanosoma parasites (Chagas disease pathogen) Whirling disease section stained with Giemsa stain. Giemsa stain (/ ˈ ɡ iː m z ə /), named after German chemist and bacteriologist Gustav Giemsa, is a nucleic acid stain used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.
Proper sampling technique is essential to avoid potential pre-analytical errors. For example, different types of samples must be collected in appropriate tubes to maintain the integrity of the sample and stored at appropriate temperatures (usually 4 °C) to preserve the virus and prevent bacterial or fungal growth.
Within the Plasmodium clade lay the genera Hepatocystis, Nycteria and Polychromophilus. Plasmodium odocoiliei appeared to be very divergent in the clade. Within the palsmodium clade the reptile species formed one grouping while the subgenera Laverinia, Plasmodium and Vinkeia also formed subgroupings. These results if confirmed suggest that the ...
