The rabbit serves as the only existing experimental model for ocular toxoplasmosis. This model has many deficiencies. Our technique for the production of acute toxoplasmic retinitis in monkeys is described herein. This primate model should be more representative than the rabbit model of human ocular toxoplasmosis.

Objective: To describe two severe cases of congenital toxoplasmosis in infants born to chronically infected mothers who did not receive education or information on the prevention of gestational toxoplasmosis during prenatal care.
Case Description: The mothers had a previous serological diagnosis of toxoplasmosis conducted during prenatal care, with non-reactive (<10 IU/mL) IgM and reactive IgG (>10 IU/mL), and were considered "immune" to the infection. Both infants were born with sequelae of the congenital infection, including neurological and ocular alterations.

Objective: Ocular toxoplasmosis, caused by , is a significant cause of posterior uveitis and vision impairment globally. Accurate diagnosis is essential to prevent retinal damage and optimise treatment. This study aimed to compare three diagnostic methods funduscopy, serology (ELISA), and PCR in detecting ocular toxoplasmosis in patients at ECWA Eye Hospital, Kano, Nigeria.

Objectives: Toxoplasmosis is a zoonotic parasitic disease caused by (), which can lead to complications such as encephalitis and ocular toxoplasmosis. The disease becomes more severe when the host's immune system is compromised. Rhoptry proteins are major virulence factors that enable to invade host cells.

Ocular toxoplasmosis is the leading cause of infectious retinochoroiditis in both adults and children. It is caused by the obligate intracellular parasite, Toxoplasma gondii. It is a common cause of posterior uveitis and focal retinitis, typically seen in immunocompetent individuals as a primary infection or in immunocompromised individuals as reactivation of latent infection.

The protozoan Toxoplasma gondii is a ubiquitous and highly prevalent parasite that can theoretically infect all warm-blooded vertebrates. In humans, toxoplasmosis causes infections in both immunodeficient and immunocompetent patients, congenital toxoplasmosis, and ocular lesions. These manifestations have different degrees of severity.
