Solved in 2 steps
- Plasmodium is the most deadly parasite globally. There are nearly 250 million new cases of malaria diagnosed each year. Discuss at least two mechanisms that this parasite uses within its host(s) to persist, manipulate, and/or propogate.What are opportunistic pathogens, facultative parasite and obligate parasitesCompare and contrast horizontal versus vertical transmission of a parasite.
- Parasites can move between hosts either by horizontal or vertical transmission. Why might those parasites that employ horizontal transmission be more impacted by environmental stochasticity? Host defenses may be impacted by environmental conditions. Pathogenicity may be impacted by environmental conditions. Vectors may be affected by environmental conditions. Vertical transmission requires a vector.Name a parasite in the environment in which it has positively impacted another organism or its ecosystem. Discuss in detail the positive impact of this parasite.Explain why parasites do not usually kill their host.
- What are two primary requirements of a parasite from host?Write at least one paragraph about the prevention and control of the following parasites: EXAMPLE: Entamoeba histolytica (fecal-oral route of transmission). Plasmodium spp. (transmitted by vector bite). Enterovirus vermicularis (fecal-oral route and autoinfection) Schistosoma haematobium (Skin penetration after water contact) Taenia seginata (ingestion of contaminated food) Ancylostoma duodenale (skin contact with soil)Describe the symbiosis between the Riftia tubeworm and its bacterial symbiont. What is the role of the Riftia tube worm hemoglobin in the success of its relationship with the symbiotic bacteria?
- A 5 year-old child was playing in their backyard. Suddenly, the child felt itchiness in his skin and began to scratch his body. Based on laboratory results, it was confirmed that the child was infected with hookworm. Answer the following questions: What possible mode of transmission the parasite has been acquired? Explain why. List all possible effects of parasite on the host. Explain each.Considering both habitat conditions and requirements for successful symbiosis, why should you be surprised that squid and the rumen of a cow have the exact same microbial symbiots?Identify and explain the parasite factors that has an impact on parasitism.
