serological detection for toxoplasmosis among patients with covid-19 in thi-qar province

Covid-19 is a viral disease that affects humans caused by a type of virus belonging to the family coronaviridae called the sars-cov-2 virus. the parasitic infection associated with this disease affects the host’s immune response regulation. the levels of igg and igm of toxoplasma gondii in the serum of patients with covid-19 were measured by immunoassay of the patient’s sera by elisa. also, the level of interferon-gamma (ifn-γ) in a covid-19 patient with or without toxoplasmosis was evaluated. 120 samples were collected, 60 were positive for covid-19, confirmed by clinically and radiographic examination, and 30 were in the control group. the results showed a significant difference between the infection with covid-19 and t. gondii during the chronic phase of toxoplasmosis compared to the negative relationship in the acute phase. the results of inf-γ levels among covid-19 patients were positive for all samples included in the test (30 covid-19 patients and 30 patients covid-19(+)/t. gondii igg) compared to the control group. the chronic form of toxoplasma disease, due to change in the production of this interferon, the covid-19 infection has changed.
