Question

Why are protozoan and helminthic diseases are difficult to treat?

Answer 1

Protozoan and helminthic diseases are difficult to treat due to their eukaryotic nature, variability within pathogens, and complex life cycles.

Step-by-step explanation:

Protozoan and helminthic diseases are difficult to treat due to several reasons:

1. Eukaryotic nature: Protozoa and helminths are eukaryotic organisms, similar to human cells. This similarity makes it challenging to develop medications that specifically target these pathogens without harming human cells.
2. Variability within pathogens: Protozoans, in particular, can vary greatly in their biology. Drugs effective against one pathogen may not be effective against another due to their differences. For example, Plasmodium pathogens that cause malaria have evolved resistance to most anti-malarial drugs.
3. Complex life cycle: Helminths, or worm parasites, need to survive within the human host to complete their life cycles. Some helminths can evade the immune system or have protective outer coatings, making them difficult to eliminate.

Answer 2

Protozoan and helminthic disease are difficult to treat because their cells are structurally similar and function same to human cells.

Step-by-step explanation:

Protozoan and helminthic disease are difficult to treat because their cells are structurally similar and function same to human cells.

There are a host of pathogenic microorganisms. These are microscopic and virus-causing organisms. For example, bacteria, such as chlamydia and Lyme disease, cause illness. Several diseases, such as human papillomavirus and common flu, are also correlated with viruses.
