- The following describes which helminthic parasite? A tiny nematode (roundworm) that lives in the human intestine; females migrate out of the anus at night to lay eggs. Most common helminthic infestation of humans in the US; spread in institutions and families through bedclothes and fingernails. Echinococcus Enterobius Diphylobothrium Trichinella None of the other four answers fit this descriptionWhat dish that, when eaten by a human host can transmit a helminthic parasite? Where could be the source of the parasite? Which ingredient could be contaminated with the parasite? How will you control the transmission of the parasite to humans?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.
- Each of the following parasite is transmitted by insect EXCEPT: Leishmania tropica Plasmodium vivax Entamoeba histolytica RickettsiaOne 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 responseWhy might the absence of a parasitic nematode in the bloodnot be a definitive proof that a patient is not suffering fromelephantiasis?
