Ochratoxin A (OA) levels were measured in blood serum of mothers foetuses and in mothers' milk. The mean concentration of OA in maternal serum was 1.14 ng/ml and in umbilical cord blood serum it was 1.96 ng/ml. The mean ratio of OA concentrations in maternal and foetal blood serum was 1.96. In maternal milk OA was found in 5 out of 13 studied samples. The mean intake of OA with mother's milk was not exceeding the tolerable daily intake for adults, nevertheless it was near 60% of TDI. The OA concentration ratio in maternal blood serum versus that in milk was 0.0058 on average. These results confirm the correlation between OA concentration maternal and foetal blood serum, and between OA concentration in maternal serum and milk.

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
