Infection of Fetal Membranes with Mycobacterium tuberculosis and Tissue Processing to Isolate RNA for Expression Analysis.

Abstract

This chapter outlines the methodology employed to infectthe chorionic and amniotic membranes with Mycobacterium tuberculosis during pregnancy. Particularly, congenital tuberculosis, a rare and serious condition associated with cases in neonates and reactivation of latent tuberculosis in pregnant mothers, is interesting to study. Understanding the mechanisms of infection and the response of fetal membranes is crucial for developing effective treatments in these cases, which will promote better neonatal and maternal health in situations of tuberculosis during pregnancy. Establishing a standardized infection model in the chorioamniotic membranes is imperative, followed by a treatment protocol for isolating both cellular and mycobacterial RNA. This will enable the expression analysis during the maternal-fetal interface interaction with M. tuberculosis. The proposed methodology might be invaluable for qRT-PCR, microarrays, and sequencing research.
