Tularemia is a disease caused by several subspecies of Francisella tularensis, although the
severity of the disease varies greatly from subspecies to subspecies. Currently, there are …

Tularemia is a zoonosis of humans caused by infection with the facultative intracellular
bacterium Francisella tularensis. Interest in F. tularensis has increased markedly in the past …

Abstract Tularemia in the United States is caused by 2 subspecies of Francisella tularensis,
subspecies tularensis (type A) and subspecies holarctica (type B). We compared clinical and …

As more original molecular protocols and subsequent modifications are described in the
literature, it has become difficult for those not directly involved in the development of these …

Francisella tularensis is an intracellular gram-negative bacterium that is highly infectious
and potentially lethal. Several subspecies exist of varying pathogenicity. Infection by only a …

Background Francisella tularensis subspecies tularensis and holarctica are pathogenic to
humans, whereas the two other subspecies, novicida and mediasiatica, rarely cause …

Francisella tularensis is a facultative intracellular gram-negative pathogen and the
etiological agent of the zoonotic disease tularemia. Recent advances in the field of …

Abstract Background. In the United States, tularemia is caused by Francisella tularensis
subsps. tularensis (type A) and holarctica (type B). Molecular subtyping has further divided …

The emergence of new pathogens and the exploitation of novel pathogenic niches by
bacteria typically require the horizontal transfer of virulence factors and subsequent …

Francisella tularensis contains several highly pathogenic subspecies, including Francisella
