Comparative Detection of Immunoglobulin Isotypes and Subclasses against Soluble Antigen in Serum and Colostrum Samples from Puerperal Women.

Background: is an obligate intracellular parasite that can infect several species, including humans, and can cause severe damage to the fetus when the infection occurs during pregnancy. The environment and/or food contamination are critical to spreading the infection. Human milk is rich in nutrients and bioactive elements that provide growth and development of the immune system of the newborn.

Evaluation of colostrum as an alternative biological sample for the diagnosis of human congenital toxoplasmosis.

Background: Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, an intracellular protozoan parasite able to infect a wide range of hosts, including humans. Congenital infection can cause severe damage to the fetus. Thus, it is important to detect antibodies against the parasite to confirm clinical manifestations.
