True about toxoplasmosis is all except
**Core Concept**
Toxoplasmosis is a parasitic infection caused by **Toxoplasma gondii**, which can affect various organs, including the brain, eyes, and lymph nodes. The infection can be congenital or acquired, and its severity varies depending on the host's immune status. **Toxoplasma gondii** is an obligate intracellular parasite that can infect a wide range of warm-blooded animals.
**Why the Correct Answer is Right**
Since the correct answer is not specified, let's discuss the general aspects of toxoplasmosis. The parasite's life cycle involves two main hosts: cats, which are the definitive hosts, and intermediate hosts, such as humans and other warm-blooded animals. In humans, toxoplasmosis can be asymptomatic or cause flu-like symptoms, while in immunocompromised individuals, it can lead to severe neurological and ocular manifestations.
**Why Each Wrong Option is Incorrect**
**Option A:** Without knowing the specific option, it's challenging to provide a detailed explanation. However, if an option states that toxoplasmosis is primarily spread through contaminated water, it would be incorrect because the primary mode of transmission is through contaminated food, cat feces, or congenitally.
**Option B:** If an option claims that toxoplasmosis only affects immunocompromised individuals, it would be incorrect because the infection can also occur in healthy individuals, although they might be asymptomatic.
**Option C:** If an option states that **Toxoplasma gondii** is a bacteria, it would be incorrect because **Toxoplasma gondii** is a protozoan parasite.
**Option D:** Without the specific option, it's difficult to provide a detailed explanation.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that toxoplasmosis can cause congenital infections if a pregnant woman becomes infected, which can lead to severe consequences for the fetus.
