- Explain what it means to be an obligate intracellular parasite.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.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.
- Which of the following are true regarding parasites in the phylum Apicomplexa? a) they are intracellular parasites b) when they are inside cells, they exist within a parasitophorous vacuole c) the phylum includes the malaria parasites d) movement of the parasites into cells involves the action of an actomyosin motor e) they only reproduce asexuallyWrite 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 a parasitic infection in cestodes in which human serves as a definitive host, as an intermediate host, and as both.
- In terms of geographical distribution, are parasitic flagellates (e.g., Trypanosoma spp., Leishmania tropica, Giardia lamblia, Trichomonas) cosmopolitan or localized? Explain Discuss the relationship between vector distribution of some parasites and their vectors, if any? Do they exhibit vector specificity?The human or animal host infected by the adult stage of a parasite worm is an: a) Intermediate host b) Final host c) Accidental host d) Vector e) Insects. I believe I know the answer but needing confirmation. ThanksWhat are opportunistic pathogens, facultative parasite and obligate parasites
- 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.Please select all of the statements that apply to chlamydial infections. (NOTE: Please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.) Check All That Apply Caused by Chlamydia trachomatis, a rod-shaped bacterium. Caused by Chlamydia trachomatis, a rod-shaped bacterium. Causative agent is an obligate intracellular parasite. Causative agent is an obligate intracellular parasite. Causative agent has two forms: elementary body and reticulate body. Causative agent has two forms: elementary body and reticulate body. Causative agent has two stages: cercaria and miracidium. Causative agent has two stages: cercaria and miracidium. Newborn babies of infected mothers can develop chlamydial eye infections.A patient consulted a doctor because of complaints of general weakness, pain in bowels, indigestion. The intestinal infection caused by Protozoa was suspected as a result of laboratory analysis. The intestinal pathogens usually transmitted through the contaminated food, water, hand. They can also be transmitted with the mechanical vectors. There are mechanical and biological vectors of disease pathogens among insects. Mechanical vectors of protozoan diseases are: Select one: a. Glossina palpalis. O b. Wohlfahrtia magnifica. c. Musca domestica. d. Phlebotomus papatasii. e. Pulex irritans.
