Study of the Disease Leishmaniasis
Leishmaniasis
Name of the disease understudy
The World Health Organization (WHO) website reports that Leishmaniasis was discovered actually many hundreds of years ago. Leishmaniasis’ signs and symptoms were described in the writings of the Inca period in the 15th and 16th centuries. According to the WHO, “One of the first and most important clinical descriptions was made in 1756 by Alexander Russell following an examination of a Turkish patient.” (XX)
Brief description of the disease
Leishmaniasis is caused by parasitic protozoa belonging to the taxonomic genus leishmania that is transported by the female sand fly. Sand flies in of them self do not contain this parasitic protozoa, they must be infected by a contaminated host, the sand fly is only the vector. When a sand fly “bites” an infected host to feed, such as rodents, the sand fly will be infected by the taxonomic genus leishmania as they feed on the infected host. As this single cell protozoa is ingested and subsequently digested, the protozoans begin to grow. As this growing occurs the sand fly then has to vomit to expel the lager of the the promastigote that have attached. As the sand fly feeds again it attempts to clear out the promastigotes clogging its intestines and esophagus through vomiting and expels promastigotes, which contain the taxonomic genus leishmania, into the bite wound of the feeding host.

Leishmaniasis can be broken down into the following three main categories:
 Cutaneous
 Mucosal
 Visceral
The cutaneous form of leishmaniasis produces whelps that lead to dermal ulcers on exposed areas of the skin. The ulcers are similar to decubitus ulcers seen in bed ridden patients. This form can difficult to diagnose since the patient may not remember how the whelp occurred since it may take weeks or months for symptom to show. This can lead the clinician to believe that the

    Lymphatic filariasis is an extremely painful infection of the lymphatic system. It is caused when thread-like filarial parasites are transmitted to humans through mosquitoes. There are three forms of the parasites which are Wuchereria bancrofti, Brugia malayi and Brugia timorican. The most common is Wuchereia bancrofti. When the mosquito bites the human, it injects the larvae into the blood stream which then circulates into the lymphatic system. The parasites can live up to six years in a human. The disease is most common in tropical areas and sub-tropical areas such as mid-Africa and southern Asia due to their elevated temperatures and moist climate CITATION Sab14 \l 1033 (Institute, 2014).…

    Parasites have evolved in a very specific and selective way throughout generations. Specific parasites have specific factors that influence their site selection process and that work in favor for the parasites. One important component that influences the parasite to become site specific is being host specific, which in turn affects the ability of extracting resources. The more efficient it is in extracting resources the better the chance of reproducing, which then increases the fitness of the parasite. Fitness plays a huge role in determining how successful the parasite may be. Few other factors that contribute to the site selection process are transmission, survival and reproduction. Since the parasites are in a very predictable environment…

    Throughout time medical technology and knowledge of the various insects and mammals which we share this earth with has continuously evolved, allowing us to discover more families and species of arthropods and also their importance to both human and veterinary life. Within these discoveries entomologist have learned of the vectors and different ways of transmission from parasites to their host. For those of the parasites that are arthropods some of them have a medical importance and some don’t; but of those which do two of the very important genus include the mosquito (Culicidae) and the tick (Ixodida). Both of which have been found to transmit several viruses and diseases some causing death depending on the severity of what that victim allows it to be.

    These flies were observed in the lab by anaesthetizing them with triethylamine so they won’t fly away. They were then inserted in a vial with a foam stopper so then it was easier to observe them. A dissecting microscope was used to identify the color of their bodies, wing shape, sex characteristics, and any other body characteristics. We used female fruit flies who were virgins six hours after they came out of their cocoons and mated them with male fruit flies. This is how crosses were made while there were a few Genetic…

The disease is transmitted by the tsetse fly which can be found all over Africa but the ones contaminated with the disease are found in region of sub-Saharan Africa. The disease has been said to have been in Africa since way back in the 14th century and one of the first epidemics that was recorded happened in 1901 in which a "devastating epidemic had erupted in Uganda, killing more than 250,000 people, about two-thirds of the population in the affected lake-shore areas" (CDC). According to the World Health Organization the disease covers 36 countries and 60 million people. The majority of the affected population live in remote areas of sub-Saharan Africa with little access to health care clinics which is why in these rural area the disease often goes untreated and misdiagnosed.…
