Imagine a newly developed drug that is highly lethal against all stages in the life cycle of Toxoplasma gondii. The drug has been found to be safe and effective both for human and for veterinary use. Although the drug can eliminate infection in both humans and cats, its use in humans will have vey little impact on overall prevalence of human toxoplasmosis. Its use in cats, alternatively, could, at least in theory, reduce prevalence in both humans and cats. Explain this difference.
Hello,
What else would you add to this explanation about "Ascaris lumbricoides", can be any cusious fact about it :)
Ascaris lumbricoides, commonly known as the human roundworm. It is a parasitic worm that infects about 772–892 million people worldwide. It belongs to a group of parasites known as soil-transmitted helminths (STH), which are spread through contact with contaminated soil. The adult worms live in the human intestine, where they can cause various health problems, especially in children. Infection usually occurs when a person consumes food or water contaminated with infective Ascaris eggs from soil. This is common in areas with poor sanitation and hygiene practices, especially in tropical and subtropical regions of Asia, sub-Saharan Africa, and the Americas (About Ascariasis, 2024).
The life cycle begins when an infected person’s feces contaminates soil with Ascaris eggs. These eggs mature and become infective, spreading to humans through ingesting contaminated food or…

- Armadillos and Leprosy The nine-banded armadillo, Dasypus novemcinctus, is the only mammal other than humans known to suffer naturally from leprosy. This mammal is also unique in that pregnant females normally give birth to identical quadruplets. Medical scientists have found D. novemcinctus to be invaluable in the study of curative agents for this disease. Suppose that a scientist has developed a drug (LeproX) that she hopes will cure leprosy in humans. She needs to test the drug first on the nine-banded armadillo to determine the effectiveness and the potential for any deleterious side effects. She exposes sixteen offspring from four litters of armadillos to the disease pathogen. When all sixteen are showing early symptoms of the leprosy, the scientist randomly divides the sixteen into two groups of eight. Each group contains two sets of four identical quadruplets. One group of eight individuals (experiment group) is treated by intramuscular (IM) injection with 0.5 mg LeproX in…arrow_forwardAssuming you have been posted to a community where malaria is very endemic.

- According to the recent malaria report of the Department of Health, Disease and Prevention Bureau (2022), there are 4, 251 confirmed cases of malaria in the Philippines and majority of the cases are due to Plasmodium falciparum. P. falciparum life cycle includes gametocytes that will aid the parasite to reproduce sexually in its anopheline vectors. Examine Figure 2 below. Provide three (3) qualitative descriptions of the P. falciparum gametocyte. Write your answers in a complete sentence. Fig. 2..

The infection presents clinically with fever, rash and swollen lymph nodes and may lead to a range of medical complications. X was first identified outside of Africa in 2003 and later reported in the United States of America, linked to contact with infected pet prairie dogs. The pets were reportedly housed with Gambian pouched rats and dormice, imported from Ghana. X has also been further reported in travelers from Nigeria to different countries around the world between 2018 and 2021. This resulted in multiple cases of X identified in several non-endemic countries in 2022, including South Africa. 3.1 Explain the clinical symptoms and laboratory diagnosis of infection X( five each)arrow_forward
