2020-10-13 Francisella tularensis is a gram-negative bacteria and the agent causing tularemia, also called rabbit fever. The species was originally discovered in squirrels in Tulare County in 1911, the county for which the bacterium is named. Francisella tularensis is a highly-infectious bacterium that causes the rapid, and often lethal disease, tularemia. Many studies have been performed to identify and characterize the virulence factors that F. tularensis uses to infect a wide variety of hosts and host cell types, evade immune defenses, and induce severe disease and death.

Outbreaks of the disease, when they occur, are usually relatively localized and rarely exceed 100 cases. Francisella tularensis is a pathogenic species of gram-negative bacteria and the causative agent of tularemia or rabbit fever. It is a facultative intracellular bacterium. 1 Due to its ease of spread by aerosol and its high virulence, F. tularensis is classified as a Class A agent by the U.S. government.2 1 Subspecies 2 Pathogenesis 2.1 Life cycle 2.2 Virulence factors 3 Genetics 4 Use as a 2020-06-01 · Francisella tularensis bacteria may be inhaled in an aerosol, with initial doses as low as ten colony-forming units (CFU) resulting in respiratory or pneumonic tularemia [7–10].

Francisella tularensis

It is sometimes referred to as rabbit fever or deer-fly fever. Serology is the preferred means of confirmation. Francisella tularensis is a gram-negative pathogen primarily of animals and occasionally of humans. The disease it causes is now recognized as tularemia in most areas of the world, but it has been called rabbit fever, deer fly fever, and market men’s disease in the United States; wild hare disease (yato-byo) and Ohara’s disease in Japan; and water-rat trappers’ disease in Russia. Overview: Francisella tularensis is a poorly staining, Gram-negative, non-motile coccobacillus bacterium, ranging from 0.2 by 0.2 to 0.7 µm in size (Figure 1). This species is highly infectious, causing the plague-like disease tularemia (also called glandular fever , rabbit fever , tick fever , and deer fly fever ) in animals and humans. Francisella tularensis.

Previous studies with the attenuated live vaccine strain (LVS) identified a role for the outer membrane protein TolC in modulation of host cell responses during infection and virulence in the mouse model of tularemia. 2020-12-01 · Francisella tularensis (F. tularensis) is a Gram-negative, facultative intracellular bacterium causing the zoonosis tularaemia . It is a class A bioterrorism agent as defined by the Centers for Diseases Control and Prevention (CDC, Atlanta, USA).

It has a thin lipopolysaccharide-containing envelope and is a hardy non-spore-forming organism that survives for weeks at low temperatures in water, moist soil, hay, straw, and decaying animal carcasses. Francisella tularensis är en gram-negativ kockobacill som är väldigt liten till storleken.
