The bacterium today known as Francisella tularensis was first identified 99 years ago and, since then, much research has been devoted to study it and the resulting disease, tularemia. F. tularensis became the focus of an intense research effort during the first half of the 20th century, in particularly in the United States and Soviet Union, since the disease was fairly common. Due to its high infectivity, ease of spread, and severity of the resulting disease, it was one of the agents given the highest priority in the biological weapon programs of the United States and Soviet Union. After termination of these programs in the 1960s, the interest in F. tularensis diminished significantly, but after several decades of little attention, the last decade has led to resurgence in the research on F. tularensis. In 2003, the Science magazine phrased it as follows: “an obscure weapon of the cold war edges into the limelight”. There were multiple reasons for this resurgence, one of which was an increase in the number of tularemia cases in several European countries and, moreover, the intense research effort on potential bioterrorist agents in the US post 9/11. Thereby, the number of annual publications on F. tularensis has tripled in 10 years, and many new research groups, in particular American, have entered the field. This has led to very rapid development of state-of-the-art research tools, and fast progress in the understanding of F. tularensis. A proof of the rapid progress was the publication of a comprehensive volume on Francisella and tularemia in 2007. Although only four years ago, the rapid pace of the research has led to many new discoveries since then and, to this end, we now present a collection of articles from leading scientists on the up-to-date knowledge regarding F. tularensis. The articles cover important areas such as molecular research tools, experimental models, genomics, virulence mechanisms, manipulation and subversion of host responses, host immune responses, and the ecology of F. tularensis.

Tularaemia is a bacterial zoonotic disease of the northern hemisphere. The bacterium (Francisella tularensis) is highly virulent for humans and a range of animals such as rodents hares and rabbits. Humans can infect themselves by direct contact with infected animals by arthropod bites by ingestion of contaminated water or food or by inhalation of infective aerosols. There is no human-to-human transmission. In addition to its natural occurrence F. tularensis evokes great concern as a potential bioterrorism agent. F. tularensis subspecies tularensis is one of the most infectious pathogens known in human medicine. In order to avoid laboratory-associated infection safety measures are needed and consequently clinical laboratories do not generally accept specimens for culture. However since clinical management of cases depends on early recognition there is an urgent need for diagnostic services. This first edition of WHO Guidelines on tularaemia provides background information on the disease describes the current best practices for its diagnosis and treatments in humans suggests measures to be taken in case of epidemics and provides guidance on how to handle F. tularensis in the laboratory. The target audience includes clinicians laboratory personnel public health workers veterinarians and any other person with an interest in zoonoses.

Tularemia is a severe anthropozoonosis caused by Francisella tularensis. The genus Francisella contains five species: F. tularensis, F. philomiragia, F. hispaniensis, F. noatunensis and F. novicida. First described in 1911 in Tulare County, California, it has since been reported worldwide, capable of infecting more than 250 vertebrates and invertebrate species. Although it causes disease in various animal species, no animal has been identified as a main reservoir of this pathogen. Humans acquire infection by several routes, including direct contact with infected animals, ingestion of water or food contaminated by infected animals, exposure to infected arthropod vectors or by inhalation of infective aerosols resulting in pneumonic, oropharyngeal, glandular, ulceroglandular or oculoglandular tularemia. The clinical presentation of human tularemia depends on route of the infection, the causative Francisella strain, and the immune response of the host. A live attenuated vaccine (LVS) has been available for more than 50 years, however, unlikely to become licensed in the future due to a lack of understanding of the genetic basis for its attenuation. Due to the ease of its dissemination, its multiple routes of infection, its low dose of infection, severe morbidity, and high rate of mortality, F. tularensis subsp. tularensis has been classified as a category A bioterrorism agent by the CDC. Many virulence factors of F. tularensis have been discovered and investigated, but more in-depth host pathogen interaction analyses are needed to define mechanisms of pathogenicity and virulence of this unique pathogen.

Francisella tularensis, the causative agent of tularemia, is a paradigm among human pathogens. This Gram-negative bacterium has an intracellular lifestyle, which probably reflects an adaptation to its natural animal and protozoa reservoirs. This is one of the most infectious agents in humans and animals; only a few bacteria are needed to induce a severe infection in both types of hosts. The clinical presentation and severity of human tularemia varies according to the portal of entry of bacteria, the bacterial inoculum, the virulence of the infecting strain, and the immune response of the host. Although most infections occur after direct inoculation of bacteria through the skin (through skin wounds or bites of arthropods), pneumonia due to inhalation of infected aerosols is the most feared of the clinical forms of the disease, particularly in the context of biological threat. Two subspecies are responsible for tularemia (subsp. tularensis and subsp. holarctica), and several clades have been described for each, which might be associated with changes in disease severity in humans. Tularemia is also more severe in people with an impaired immune response. No safe vaccine is currently available for prophylaxis of tularemia in humans. On the other hand, control of proliferation of F. tularensis in wildlife is not feasible. Thus, only the anti-infective agents are used for treatment and prophylaxis of human tularemia. The standard options include aminoglycosides (gentamicin), tetracyclines (eg, doxycycline) and fluoroquinolones (eg, ciprofloxacin). The selection of acquired resistance to these antibiotics in F. tularensis, especially in the context of a biological threat, may quickly limit the therapeutic options. New prophylactic and therapeutic alternatives must be developed rapidly. The present Research Topic focuses on potential new strategies for treatment of tularemia, including the development and evaluation of new compounds having proper antibacterial activity, reducing the virulence of F. tularensis or enhancing the immune host response.

"Tularemia is a highly infectious disease caused by the bacterium Francisella tularensis. Infections in humans are not contagious and most often result from contact with infected wildlife, ingestion of or contact with contaminated water, or bites from ticks and other arthropods that have fed on infected wildlife. Aerosol transmission is another way humans can become infected. Disease is expressed in different clinical forms, and varies in severity depending on the virulence of the organism, dose, and site of inoculum. Tularemia has a broad geographic distribution in the Northern Hemisphere and is more restricted elsewhere. A wide variety of species have been naturally infected by F. tularensis; the number of species reported to be susceptible to infection exceeds 300, according to a recent report, which does not include some of the cold-blooded species such as fish and snakes reported by others."--Overview.
