- Label the stages of the Trypanosoma cruzi life cycle as well as the form of the parasite in each stage. Drag the appropriate labels to their respective targets..In the following diagram of the life cycle of Chlamydia tra-chomatis, identify numbered stages 1–6 and parts (a)–(d).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.
- Illustrate and describe the life cycle of the following: Ancylostoma duodenaleOne 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 responseIdentify the intermediate and definitive hosts in trematode infestation.
