Step by step
Solved in 2 steps
- What are the factors affecting the pathogenicity of a parasitic amoeba? Explain.what is the symbiotic relationship between aspergillus fumigatus and human skinWhat parasite is commonly mistaken as Entamoeba histolytica and why?Why is Entamoeba histolytica often termed as “clinically significant amoebic parasite”?
- What parasite is commonly mistaken as Entamoeba histolyticaamoebas Euglenozoa Ciliates of the phylum Ciliophora Apicomplexans For each of the groups listed above, provide one example of a pathogenic protozoan found in the U.S.ADescribe the life cycle of Toxoplasma gondii, where does Toxoplasma "want" to be? How does toxo gets into rats and deal with the problems of being stuck in the wrong host animal?

What is the role of the Riftia tube worm hemoglobin in the success of its relationship with the symbiotic bacteria?Illustrate the life histories of the parasites Trypanosoma brucei rhodesiense and Plasmodium vivax. please include a flowchart for both.Why is Entamoeba histolytica often termed as clinically significant amoebic parasite
- One of the most characteristic symptoms of malaria is the alternation of attacks (involving a cold phase, a hot phase, and a sweating phase) with periods of 1 or 2 days of no or few fevers. Given the life cycle of Plasmodium what is the best explanation for this pattern: When free in the blood, merozoites release chemicals that directly cause body responses. Merozoites appear in coordinated “waves”, which explains the cycling attacks Merozoites entering the red blood cells generate a strong response from the red blood cells, which stimulates a massive immune response Attack phase correlates with simultaneous bursting of infected red blood cells, releasing thousands or millions of merozoites. This triggers massive immune response, resulting in symptoms Plasmodium generates a constant accumulation of irritants in the blood, mostly residues from digesting hemoglobin . Once the amount reaches a critical level, these trigger a massive immune responseAspergillus fumigatus may cause pulmonary mold infections in immunocompromised patients. Which of the following structures causes the tissue destruction in the patients: tissue destruction by enterotoxins tissue destruction by pseudohyphae none of the above apply tissue destruction by cysts tissue destruction by plaque formation tissue destruction by aerial hyphae tissue destruction by vegetative hyphaeIdentify the type of protist that causes each of the followingdiseases: malaria, African sleeping sickness, and amoebicdysentery.
