Outer membrane tube formation by Francisella novicida involves extensive envelope modifications and is linked with type VI secretion and alterations to the host phagosomal membrane

mBio
Francisella tularensis is a gram-negative, intracellular pathogen that causes the zoonotic disease tularemia. Due to its ease of dissemination and high lethality, F.

Characterization of carABpyrB operon and role of pyrE in Francisella novicida biofilm

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Pyrimidine biosynthesis links metabolism to biofilm regulation in Francisella novicida. During nutrient limitation, reduced pyrimidine availability shifts metabolism from uracil salvage to de novo synthesis, increasing biofilm formation. Mutants in carABpyrB exhibit uracil‐dependent growth defects and elevated biofilm:growth ratios, revealing ...

Francisella tularensis interactions with the lung [PDF]

, 2008
Francisella tularensis, a gram-negative bacterium, is the etiological agent of the human disease, tularemia. Inhalation of as few as 10 bacteria can result in a rapidly progressing, disseminating, and often lethal infection.

Mucosal‐Associated Invariant T Cells in Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
The roles of MAIT cells in health and disease and their therapeutic applications. In healthy individuals, riboflavin metabolites secreted by commensal bacteria at mucosal sites are presented by MR1, leading to the activation of MAIT cells. Activated MAIT cells can maintain the barrier integrity of mucosal tissues in a steady state or migrate to the ...

INTRAVACUOLAR LIFE CYCLE OF FRANCISELLA NOVICIDA IN DICTYOSTELIUM DISCOIDEUM

, 2019
Cilj istraživanja: Francisella novicida je unutarstanična bakterija koja može inficirati brojne stanice uključujući i stanice ameba. Pretpostavlja se da amebe imaju važnu ulogu za održavanje francizela u vodenom okolišu.

Monocyte / macrophage inflammatory response pathways to combat Francisella infection: possible therapeutic targets?

Frontiers in Cellular and Infection Microbiology, 2014
Francisella tularensis can bypass and suppress host immune responses, even to the point of manipulating immune cell phenotypes and intercellular inflammatory networks. Strengthening these responses such that immune cells more readily identify and destroy

Genomic and Phenotypic Classification of Staphylococcus Species Isolated From Delhi Air

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Multiple Staphylococcus spp. were isolated from the outdoor polluted air of the Indian Capital, New Delhi. The bacterial samples were collected from 6 different locations, and the whole genome of four Staphylococcus isolates was sequenced in their entirety. This study presents the comparative genomic analysis of these four isolates.
