Step by step
Solved in 2 steps
- What is the cause of malaria? Why does the presence of sickle cell trait confer resistance to some types?Even though genetically engineered mosquitoes might be developed that do not allow the reproduction of malaria protozoa, these mosquitoes would have little, if any, immediate effect on the spread of the disease. Why should this be so? What would have to happen for these mosquitoes to significantly affect the spread of malaria?With the help of a well – labelled diagram, Describe the life cycle of malarial 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 responseHello!Discuss the advantages and disadvantages of targeted vs mass control for zoonotic malaria. ( if you can also link an article which mentions this It will be much appreciated). thank you!Why do only female mosquitoes transmit malaria?
- According to the recent malaria report of the Department of Health, Disease and Prevention Bureau (2022), there are 4, 251 confirmed cases of malaria in the Philippines and majority of the cases are due to Plasmodium falciparum. P. falciparum life cycle includes gametocytes that will aid the parasite to reproduce sexually in its anopheline vectors. Examine Figure 2 below. Provide three (3) qualitative descriptions of the P. falciparum gametocyte. Write your answers in a complete sentence. Fig. 2.. Plasmodium falciparum gametocyte in thin blood smear (CDC, 2022)Explain why there is no malaria above 6,000 feet in altitude.Describe the malaria is and where it is prevalent- in what areas of the globe and in what habitats?( find the source that support the information)
- Which is considered as the intermediate host and the definitive host in the life cycle of malarial parasite?Seasonality of a disease can relate to weather patterns rather than seasons. Malaria is a prime example and has a seasonality related to water and the wet season vs. the dry season. Explain why considering the vector.Outline the general life cycle of malarial organisms. What explains the resurgence of malaria in recent years?
