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.
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
This drug has been shown to be effective in killing both the adult worm of O. volvulus and Wolbachia, the bacteria believed to play a major role in the onset of onchocerciasis, while having no effect on the microfilariae of L. loa. In a study done at five different co-endemic regions for onchocerciasis and loiasis, doxycycline was shown to be ...
Filariasis is usually diagnosed by identifying microfilariae on Giemsa stained, thin and thick blood film smears, using the "gold standard" known as the finger prick test. The finger prick test draws blood from the capillaries of the finger tip; larger veins can be used for blood extraction, but strict windows of the time of day must be observed.
Leishmania tropica is a flagellate parasite and the cause of anthroponotic [dubious – discuss] cutaneous leishmaniasis in humans. [2] This parasite is restricted to Afro-Eurasia and is a common cause of infection in Afghanistan, Iran, Syria, Yemen, Algeria, Morocco, and northern India. [3]
A blood sample was taken at 11:00 am, and examined microscopically as a thick blood film stained with Giemsa's solution. The thick blood film revealed the presence of M. perstans, and no other parasites were found. He had 3% eosinophilia. A visual acuity test showed a reduction of visual acuity to 4/10 for the left eye, while the right eye was ...
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.
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)
