 This study investigated the seroprevalence of toxoplasmosis and the distribution of ABO and rhesus factor blood groups among women with a history of abortion in Erbil, Iraq. The results showed that 33.5% of the participants had anti-toxoplasma IgM antibodies and 65% of these individuals were RhD negative. Additionally, there was a significant association between RhD blood type and toxoplasmosis seropositivity. No significant associations were found between toxoplasmosis and either ABO phenotypes or demographic characteristics. Overall, this study suggests that the prevalence of toxoplasmosis is higher than expected in Erbil, Iraq and that RhD blood type may be associated with increased susceptibility to the infection.
