Phenotypic characterization of the Francisella tularensis ΔpdpC and ΔiglG mutants

, 2016
Several bacterial pathogens interact with their host through protein secretion effectuated by a type VI secretion system (T6SS). Francisella tularensis is a highly pathogenic intracellular bacterium that causes the disease tularemia.

Environmental adaptation of Francisella tularensis [PDF]

Microbes and Infection, 2009
Concerns over weaponizable bacteria have recently prompted considerable interest in Francisella tularensis (Ft). In addition to its potential illicit use, Ft occurs naturally in diverse ecological niches including mammals, arthropods, and fresh water protozoans.

Francisella tularensis infection in a stone marten (Martes foina) without classic pathological lesions consistent with tularemia. [PDF]

, 2013
The current report describes the isolation and typing of a strain of Francisella tularensis, the causative agent of tularemia, from the spleen of a stone marten (Martes foina) showing no classic lesions consistent with the disease.

Increased Pediatric Head and Neck Abscesses Following the COVID‐19 Pandemic

The Laryngoscope, EarlyView.
This study evaluated the impact of the COVID‐19 pandemic on pediatric head and neck abscesses at two tertiary care centers. Overall head and neck abscess incidence increased more than threefold in the post‐pandemic period compared with the pre‐pandemic period, with increases observed across all major abscess subtypes.

Atomic Structure of IglD Demonstrates Its Role as a Component of the Baseplate Complex of the Francisella Type VI Secretion System

mBio, 2022
Francisella tularensis, a Tier 1 select agent of bioterrorism, contains a type VI secretion system (T6SS) encoded within the Francisella pathogenicity island (FPI), which is critical for its pathogenesis.

Ecological Niche Modeling of Francisella tularensis Subspecies and Clades in the United States

, 2010
Two subspecies of Francisella tularensis are recognized: F. tularensis subsp. tularensis (type A) and F. tularensis subsp. holartica (type B). Type A has been subdivided further into A1a, A1b, and A2, which differ geographically and clinically.

Putting Rodents at the Center of One Health Programs: A Narrative Synthesis

Integrative Zoology, EarlyView.
Rodents link human, animal, and environmental health across diverse ecosystems. Rodent diversity underpins both zoonotic disease risk and ecosystem function. Environmental change reshapes rodent communities and spillover dynamics. Rodents act as reservoirs, amplifiers, and sentinels of emerging pathogens.

Genome characterisation of the genus Francisella reveals insight into similar evolutionary paths in pathogens of mammals and fish

BMC Genomics, 2012
Background Prior to this study, relatively few strains of Francisella had been genome-sequenced. Previously published Francisella genome sequences were largely restricted to the zoonotic agent F. tularensis.

Regulation of apoptosis and anti-apoptosis signalling by Francisella tularensis

, 2010
Francisella tularensis induces apoptosis within macrophages but the temporal and spatial modulation through activation of caspase-1, caspase-3, and the anti-apoptosis nuclear transcription factor B (NF-kappaB) is not known. Whether escape of the bacteria
