Toxoplasma gondii infections in birds, companion, food and recreational animals in Nigeria: A systematic review and meta-analysis.

Toxoplasma gondii is a protozoan pathogen of zoonotic and economic importance with a global distribution. The pathogen is associated with abortion, stillbirth, neonatal mortalities and mummification in sheep and goats which may also serve as sources of human infections. In pregnant women, the parasite undergoes intrauterine transmission to cause neonatal complications like miscarriage, chorioretinitis, hydrocephalus, cerebral calcification and foetal death.
