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

The Laryngoscope, Volume 136, Issue 11, Page 5062-5071, November 2026.
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.

Francisella tularensis Bacteremia [PDF]

Journal of Clinical Microbiology, 2003
ABSTRACT Bacteremia caused by Francisella tularensis is rare and has been reported mainly in the United States and infrequently in Europe. We report herein the first case of bacteremic F. tularensis pneumonia in an immunocompetent individual in southern Europe.

AR-13, a Celecoxib Derivative, Directly Kills Francisella In Vitro and Aids Clearance and Mouse Survival In Vivo

Frontiers in Microbiology, 2017
Francisella tularensis (F. tularensis) is the causative agent of tularemia and is classified as a Tier 1 select agent. No licensed vaccine is currently available in the United States and treatment of tularemia is confined to few antibiotics.

Microbial Characteristics of Weissella cibaria HRL3 and Its Immunostimulatory Effects via TLR3/TLR9‐Dependent IFN‐α Production

Journal of Food Science, Volume 91, Issue 11, November 2026.
ABSTRACT Rhinacanthus nasutus (L.) Kurz is a medicinal plant whose roots, stems, and leaves are commonly used in tea and traditional Chinese medicine; however, the beneficial effects of its flowers remain to be investigated. In this study, the lactic acid bacteria (LAB) found in the flowers of R.

Francisella and tularemia in western Asia, Iran: a systematic review

New Microbes and New Infections, 2023
Tularemia or rabbit fever is a transmissible disease from animals, rodents, and insects to human populations that is caused by Francisella tularensis. Epidemiological studies showed that tularemia is endemic throughout most different regions of the world.

Virulent Type A Francisella tularensis actively suppresses cytokine responses in human monocytes

Frontiers in Cellular and Infection Microbiology, 2014
Francisella tularensis is a Gram-negative facultative bacterium that can cause the disease tularemia, even upon exposure to low numbers of bacteria. One critical characteristic of Francisella is its ability to dampen or subvert the host immune response ...

The immunologically distinct O antigens from Francisella tularensis subspecies tularensis and Francisella novicida are both virulence determinants and protective antigens.

, 2006
We have determined the sequence of the gene cluster encoding the O antigen in Francisella novicida and compared it to the previously reported O-antigen cluster in Francisella tularensis subsp. tularensis.

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 ...

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.

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 ...
