Leishmania major

Leishmania major is a microscopic parasite that causes cutaneous leishmaniasis, a skin infection characterized by lesions that can develop into ulcers. It is found primarily in certain hot, arid regions of Africa, the Middle East, and Asia. The parasite is transmitted to humans through the bite of infected sandflies, small insects similar to mosquitoes.

Once inside the skin, Leishmania major causes the appearance of small papules that can enlarge and develop into painless, red ulcers. These lesions can persist for several weeks or months and sometimes leave scars after healing. The disease generally does not affect a person's overall health, but it can be bothersome or painful depending on the location and size of the lesions.

Treatment relies on specific antiparasitic medications administered according to medical recommendations. To prevent infection, it is important to reduce exposure to sandfly bites by using mosquito nets, repellents, and protective clothing, and by avoiding areas where the insects are active, especially at dusk and at night.

With its fascinating shape and intriguing life cycle, Leishmania major makes a perfect science sticker for microbiology and parasitology enthusiasts. Add it to your collection to explore the invisible world of parasites!
