Sero-Prevalence of Toxoplasma gondii Infection in Humans in Khartoum State, Sudan

Abstract

Toxoplasma gondii is one of the most common parasites that cause infection to human. The aim of this study was to conduct a sero-prevalence survey of toxoplasmosis in several target groups. A total of 1146 serum samples were collected and detected against Toxoplasma gondii antibodies using LAT. Five hundred (out of 1146 cases) were positive cases giving prevalence rate of (43.6%). High a prevalence was found among HIV patients (75%), aborters (58.3%) and suspected cases (55.5%). More positive cases were detected by (LAT) in age groups (26-30) years than other groups (p = 0.0001). Prevalence rate by sex was found to be higher in females than males (p<0.05). Residence was found to be significant in rural areas (p = 0.001). The relationship between positive (LAT) and women who aborted was significant (p<0.05). Contact with cats, eating raw meat and eating soil were significant to infection using (LAT) (p = 0.0001, p = 0.0001 and p = 0.006), respectively. High prevalence of Toxoplasma gondii was recorded in Khartoum State.
