Trypanosoma cruzi, the protozoan agent of Chagas disease in the Americas, is comprised of six genetic lineages (TcI-TcVI) and a possible seventh (TcBat, related to TcI). Identification of T. cruzi lineages infecting reservoir mammalian species is fundamental to resolving transmission cycles.

Article Synopsis
  • Intracellular bacteria like Brucella abortus must manage DNA damage caused by alkylating agents when they infect host cells, particularly in macrophages.
  • The study shows that B. abortus relies on specific genes for DNA repair, highlighting the role of both direct and base-excision repair mechanisms during this stress.
  • Notably, the gene ogt, essential for DNA repair, is regulated by the transcription factor GcrA, indicating unique features of DNA repair in B. abortus compared to well-studied bacteria like Escherichia coli.

Background: Trypanosoma cruzi, the protozoan agent of Chagas disease, is comprised of at least 6 genetic lineages (TcI-TcVI). Their geographical distribution, clinical associations and reservoir hosts are not fully elucidated, as genotyping is hampered due to the difficulty in isolating representative populations of organisms. Lineage-specific serological techniques may address these issues.
