Introduction

Toxoplasma gondii is an obligate intracellular parasitic protozoan that causes toxoplasmosis. It is a prevalent parasite, affecting approximately one-third of the world's human population. The infection is of particular concern for pregnant women and individuals with weakened immune systems.

Symptoms of Toxoplasma gondii Infection

While many infected individuals are asymptomatic, others may exhibit a variety of symptoms. The severity and type of symptoms largely depend on the immune status of the host.

General Population

1. Asymptomatic: Approximately 80-90% of healthy individuals show no symptoms.
2. Mild Flu-like Symptoms: 10-20% may experience muscle aches, fatigue, or fever.
3. Lymphadenopathy: Swollen lymph nodes are reported in 5-10% of cases.

Pregnant Women

1. Congenital Toxoplasmosis: Affects 1-4 per 10,000 live births in countries with high infection rates.
2. Developmental Delays: May lead to severe outcomes such as intellectual disabilities or vision loss.

Immunocompromised Individuals

1. Severe Neurological Symptoms: Encephalitis and seizures occur in 10-30% of cases among HIV-positive individuals.
2. Systemic Infections: Disseminated toxoplasmosis can affect lungs, heart, and other organs.
