Which of the following statements about Toxoplasma gondii is correct? Vertical transmission is the most common route of transmission for Toxoplasma infections in humans. Due to the presence of domestic and feral cats, North America is a region of high Toxoplasma seroprevalence. Circulating IgG antibodies to Toxoplasma antigens can be detected in a human host who experienced a previous infection many years ago. The innate and adaptive immune system eliminates all the tissue cysts during a chronic Toxoplasma infection. Acute Toxoplasma gondii infections always require chemotherapeutic treatment.
Understand the Problem
The question is asking us to identify which one of the provided statements about Toxoplasma gondii is correct. It presents multiple assertions regarding the transmission, seroprevalence, immune response, and treatment of Toxoplasma infections, and aims to clarify the accuracy of these claims.
Answer
Circulating IgG antibodies to Toxoplasma antigens can be detected in a human host who experienced a previous infection many years ago.
Circulating IgG antibodies to Toxoplasma antigens can be detected in a human host who experienced a previous infection many years ago.
Answer for screen readers
Circulating IgG antibodies to Toxoplasma antigens can be detected in a human host who experienced a previous infection many years ago.
More Information
When a person is infected with Toxoplasma gondii, their immune system produces IgG antibodies that remain detectable for years, indicating past infection.
Tips
A common mistake might be assuming that vertical transmission is the most common when it is not. Horizontal transmission, particularly through undercooked meat, is more common.
