Staphylococcus aureus ftnA 3’-Untranslated Region Modulates Ferritin Production Facilitating Growth Under Iron Starvation Conditions

Autor: Pilar Menendez-Gil, Arancha Catalan-Moreno, Carlos J. Caballero, Alejandro Toledo-Arana

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

Iron acquisition and modulation of its intracellular concentration are critical for the development of all living organisms. So far, several proteins have been described to be involved in iron homeostasis. Among them, ferritins act as the major iron

Bakaletz, Garth D. Ehrlich, Eric A. Porsch, Margarita Menéndez, Joshua C. Mell, Alejandro Toledo-Arana, Junkal Garmendia

Publikováno v: mBio, Vol 12, Iss 3 (2021)

Human-adapted bacterial pathogens have evolved specific mechanisms to colonize their host niche. Phase variation is a contingency strategy to allow adaptation to changing conditions, as phase-variable bacterial loci rapidly and reversibly switch thei

Bacterial viruses enable their host to acquire antibiotic resistance genes from neighbouring cells

Autor: Jakob Haaber, Jørgen J. Leisner, Marianne T. Cohn, Arancha Catalan-Moreno, Jesper B. Nielsen, Henrik Westh, José R. Penadés, Hanne Ingmer

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)

Prophages are quiescent bacterial viruses that, when activated, produce viral particles and kill their host cells. Here, Haaber et al. show that these viral particles can mediate the transfer of antibiotic resistance genes from neighbouring cells bac

Bacterial genomes are pervasively transcribed, generating a wide variety of antisense RNAs (asRNAs). Many of them originate from transcriptional read-through events (TREs) during the transcription termination process. Previous transcriptome analyses

Thermoregulation of virulence genes in bacterial pathogens is essential for environment-to-host transition. However, the mechanisms governing cold adaptation when outside the host remain poorly understood. Here, we found that the production of cold s
