- 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 responseA 31 year old male who emigrated from Mexico 3 years prior to admission, was brought to the hospital by his family with a convulsions and Epileptic seizures. He had been previously healthy. A CT scan of the head showed multiple small cystic and calcified lesions. Blood count analysis shows low eosinophil levels. What kind of parasite that give this symptom? Extraintestinal infection of Entamoeba histolytica cyst Taenia solium larva cysticercus cellulose Ascaris lumbricoides larva migration O Taenia saginata adult worm O Option 5On July 10, a man in Palm Beach, Flroida, was admitted to the hospital with a month-long history of fever, chills, profuse sweating, headache, and occasional vomiting. A parasite was observed in a blood smear. What parasite causes these signs and symptoms? What is the treatment? Is this a rare disease in Florida?
- Name the parasite causing malaria.Which of the following is NOT a true statement? Human Schistosoma infestations are transmitted by direct person-to-person contact without an intermediate host If Schistosoma eggs are circulated in the blood, they can lodge in distant organs Schistosoma adults lay their eggs into the intestine, where they are shed in feces Granulomas form around Schistosoma eggs and can damage internal organs (liver, lungs, etc.) Schistosoma flukes (trematodes) inhabit the intestinal blood vessels for part of their life cycleName the pathogen which causes malignant malaria.
