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.
Leishmania major is a species of parasite found in the genus Leishmania, and is associated with the disease zoonotic cutaneous leishmaniasis (also known as Aleppo boil, Baghdad boil, Bay sore, Biskra button, Chiclero ulcer, Delhi boil, Kandahar sore, Lahore sore, Oriental sore, Pian bois, and Uta).

Parasites need a host body and the haematophagous insect triatomine (descriptions "assassin bug", "cone-nose bug", and "kissing bug") is the major vector in accord with a mechanism of infection. The triatomine likes the nests of vertebrate animals for shelter, where it bites and sucks blood for food.
The blood sample can be a thick smear, stained with Giemsa or haematoxylin and eosin. For increased sensitivity , concentration techniques can be used. These include centrifugation of the blood sample lyzed in 2% formalin (Knott's technique), or filtration through a nucleopore membrane .
Giemsa-stained thin blood smear: New England (different species have worldwide distribution) tick bites, e.g. Ixodes scapularis: Balantidiasis: Balantidium coli: intestinal mucosa, may become invasive in some patients stool (diarrhea=ciliated trophozoite; solid stool=large cyst with horseshoe shaped nucleus)
Leishmaniasis is a wide array of clinical manifestations caused by protozoal parasites of the Trypanosomatida genus Leishmania. [7] It is generally spread through the bite of phlebotomine sandflies, Phlebotomus and Lutzomyia, and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe.

The definitive diagnostic test is the identification of parasites on a Giemsa-stained thin-film blood smear. [ 13 ] So-called "Maltese cross formations" on the blood film are diagnostic ( pathognomonic ) of babesiosis, since they are not seen in malaria, the primary differential diagnosis. [ 11 ]
