Suramin Analysis

The best way to combat the infection is to seek medical treatment were specific drugs can be used to remove the protozoan from the body. When in the first stage the most effective drug for T. brucei rhodesiense is Suramin. The most effective way for the drug to be administered is intravenously because it is not absorbed well by the intestines. It’s most effective against trypomastigotes that are in the bloodstream. The drug acts upon T. b. rhodesiense by inhibiting the glycosomal enzymes involved in glycolysis, the bloodstream form's only source of energy. This inhibition happens at a slow and gradual rate and it is even possible that suramin might affect newly-synthesized glycolytic enzymes within the cytosol before they are imported into …show more content…
When a foreign microbe enters the body a natural immune response is initiated to protect the body from harm. However, when the body cannot detect when it has been invaded the appropriated self-preservation responses cannot be enacted to fend off invaders. Without identification of the invading microbe the immune system resorts to innate responses, or non-specific responses, such as fever, inflammation, pain in the joints, and occasionally irritation of the skin at the infection site. In the case of the Trypanosoma family the first stage consist of continuous waves of parasites in the blood also known as parasotaema. The immune system begins to target the protozoans and is able to remove some of them however, they begin evading the immune system through a process called antigenic variation. During this process, the trypanosome switches its variable surface glycoprotein (VSG) coat, which the antibodies of the immune system use to recognize invading cells, to a new VSG coat that is not recognized by the host immune system. This continuous action exhausts the host immune defenses leading to weaker response. The process of evasion also includes endocytosis of VSG-antibody complexes, allowing them to escape detection by the antibodies responsible for complement-mediated killing.2 Antigenic variation prolongs the time that trypanosomes spend within the host, thus allowing for further proliferation and transmission to other hosts via the tsetse vector. This process also allows trypanosomes to infect hosts that already recognize VSGs from prior

    The Bubonic Plague is a bacteria known as Yersinia Pestis that infects the lymphatic system causing it to become inflamed (Tonsils, Adenoids, Spleen, and Thymus). The bacteria needs calcium to grow but when there is no calcium it produces amino acids called aspartic acid. Aspartic acid raises the blood plasma level of aspartate and glutamate. This excess can lead to damage of sensitive neurons. It can also help generate cellular energy, balance neurochemistry, and help the liver rid the body of toxins including ammonia.…

    The main lesion in chronic schistosomiasis represents a complex delayed-type hypersensitivity response to sequestered living, dying or dead ova, that are trapped in tissues during the peri-intestinal migration or after embolization in the liver. Soluble egg antigen (SEA) and proteolytic enzymes released by ova provoke granulomatous cell-mediated immune response, with recruitment of eosinophils, granuloma formation and liver fibrosis (Cheever et al., 2000; Wynn et al., 2004). In schistosomiasis, Th2-type cytokine production becomes predominant eight weeks post infection, while Th1 cytokines decrease as Th2 cytokines increase i.e. cross-regulation of cytokine production (Stavitsky, 2004). Granuloma formation in the liver could be differentiated into two phases: a lytic pre-granulomatous phase (exudative phase), which produces a spherical space by destruction of parenchyma for the final establishment and organization of the lesion, and a granulomatous cellular phase (Steinberg, 1996).…

    The article "Sleeping Sickness Parasite has a weak spot in its tail” by Catherine Brahic, is a very brief summary about a parasite,Trypanosoma brucei, passed to humans from the tsetse fly. The sleeping sickness is responsible for 50,000 deaths a year in Africa. Brahic states that they have discovered that the parasite cannot reproduce if its whip-like tail or "flagellum" stops working. Although they are still unsure, as to why the flagellum exists. Keith Gull of Oxford University has a theory, that it assists the parasite to split in two when multiplying in the bloodstream.…

    1. The organism that is the cause of this patient’s illness is Legionella pneumpohila, which means the patient has Legionnaire’s disease. Although there are other organisms that can cause similar diseases, it is clear that Legionella pneumpohila is the organism responsible for this patient’s disease. There are several reasons, but the one that stands out the most is that this organism can only grow on buffered charcoal-yeast extract, which is why there was no growth present on the 5% sheep blood agar. Other contributing factors which make it well-defined that this organism is the agent of disease are that the symptoms the patient had go along with what was exactly listed for the disease as well as the fact that Legionella pneumpohila often…

The immune system, which is responsible for defending the body against pathogens, is a very complex and vital body system. The immune system involves both innate and adaptive immunity. Innate immunity functions as the “first responder” system of the body. The skin, the mucous membranes are the first line of defense in innate immunity.…
