IntroductionNot many people in the United States have come into contact with a disease called leishmaniasis; however, in southern Europe and the tropics of the world this disease is a force to be reckoned with. Leishmania spp., also known more commonly as cutaneous leishmaniasis and visceral leishmaniasis, is a bacterium that causes a parasitic disease on the surface of the skin or within the body in internal organs. An experiment was conducted to see if leishmaniasis should be included in the CDC's clinical category C for the definition of AIDS. Context Leishmania spp. It belongs to the kingdom of archaebacteria and eubacteria. It is a bacterium that causes a parasitic disease found in the tropics, subtropics, and southern Europe and rarely found in the United States (parasites - leishmaniasis). It is prokaryotic and unicellular. Its energy source comes from the synthesis and consumption of its own energy from sunlight, inorganic and organic compounds, as well as autotrophs and heterotrophs. It is asexual and can use binary fission to reproduce. Since it is a parasite, it attacks other organisms in addition to using a chemical defense. Bacteria can live and survive in harsh environments with or without oxygen. A cell wall is present. Leishmaniasis is caused by infection with Leishmania parasites, which are spread through the bite of infected sandflies (Parasites - Leishmaniasis). The most common forms are cutaneous leishmaniasis and visceral leishmaniasis. The cutaneous one causes skin sores while the visceral one affects various internal organs, including the spleen, liver and bone marrow (Parasites - Leishmaniasis). Sometimes the skin infection can be a silent infection, without any symptoms or signs. The people developing clinical trials… half of the paper… ate stages of the HIV virus, as demonstrated by the case study and results figure. Visceral leishmaniasis in the HIV-infected population should be included in CDC clinical category C for the definition of AIDS.Works CitedParasites - Leishmaniasis. (2013, January 10).
