Francisella and Antibodies [PDF]

open access: yesMicroorganisms, 2021
Immune responses to intracellular pathogens depend largely upon the activation of T helper type 1-dependent mechanisms. The contribution of B cells to establishing protective immunity has long been underestimated.

Comparative Transcriptional Analyses of Francisella tularensis and Francisella novicida. [PDF]

open access: yesPLoS ONE, 2016
Francisella tularensis is composed of a number of subspecies with varied geographic distribution, host ranges, and virulence. In view of these marked differences, comparative functional genomics may elucidate some of the molecular mechanism(s) behind ...

First case of Francisella bacteraemia in Western Australia

open access: yesNew Microbes and New Infections, 2015
Francisella species are Gram-negative, nonmotile, pleomorphic coccobacilli, facultative intracellular fastidious bacteria. We report the isolation of a Francisella-like species from a blood culture collected from a 44-year-old bacteraemic patient in ...

Azithromycin effectiveness against intracellular infections of Francisella [PDF]

open access: yesBMC Microbiology, 2010
Background Macrolide antibiotics are commonly administered for bacterial respiratory illnesses. Azithromycin (Az) is especially noted for extremely high intracellular concentrations achieved within macrophages which is far greater than the serum ...

Co-Occurrence of Francisella, Spotted Fever Group Rickettsia, and Midichloria in Avian-Associated Hyalomma rufipes

open access: yesMicroorganisms, 2022
The migratory behavior of wild birds contributes to the geographical spread of ticks and their microorganisms. In this study, we aimed to investigate the dispersal and co-occurrence of Francisella and spotted fever group Rickettsia (SFGR) in ticks ...

Francisella induced microparticulate caspase-1/gasdermin-D activation is regulated by NLRP3 independent of Pyrin.

open access: yesPLoS ONE, 2018
Although the study of pathogen sensing by host defense systems continues to uncover a role for inflammasome components specific to particular pathogens, gaps remain in our knowledge.

The Francisella intracellular life cycle: towards molecular mechanisms of intracellular survival and proliferation [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2010
The tularemia-causing bacterium Francisella tularensis is a facultative intracellular organism with a complex intracellular lifecycle that ensures its survival and proliferation in a variety of mammalian cell types, including professional phagocytes ...

Characterization of carABpyrB operon and role of pyrE in Francisella novicida biofilm. [PDF]

open access: yesMicrobiologyopen
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 ...

Increased knowledge of Francisella genus diversity highlights the benefits of optimised DNA-based assays [PDF]

open access: yesBMC Microbiology, 2012
Background Recent advances in sequencing technologies offer promising tools for generating large numbers of genomes, larger typing databases and improved mapping of environmental bacterial diversity.
