It is a rare disease spread by infected rodents and caused by two specific types of bacteria: Streptobacillus moniliformis, the only reported bacteria that causes RBF in North America (streptobacillary RBF) Spirillum minus, common in Asia (spirillary RBF, also known as sodoku). Most cases occur in Japan, but specific strains of the disease are ...
In 1832, the genus Spirillum was created and encompassed an array of helical bacteria. In 1957, the large genus was reviewed and narrowed to include 19 species based on morphology and a few other physiological characteristics.
Sodoku is a bacterial zoonotic disease. It is caused by the Gram-negative rod Spirillum minus (also known as Spirillum minor ). It is a form of rat-bite fever (RBF).
Spirillum minus is an organism associated with rat-bite fever (specifically sodoku) [2] [3] [4] that has never been fully identified and was assigned to the genus Spirillum in 1887 based on morphology, although it is not a validly published name.
Spirillum is a of Gram-negative bacteria in the family Spirillaceae of the Nitrosomonadales of the Betaproteobacteria. [ 1 ] [ 2 ] [ 3 ] There are two species of Spirillum with validly or effectively published names - Spirillum winogradskyi and Spirillum volutans .
Vincent's angina (also termed Plaut–Vincent's angina), [1] [2] is pharyngitis (inflammation of the pharynx) and tonsillitis (inflammation of the palatine tonsils), caused by infection with two types of bacteria called fusiform (Fusobacterium spp.) [3] and spirochaetes (Borrelia spp. [3] and Spirillum spp.). [4]
Rat bite fever is caused by either Streptobacillus moniliformis or Spirillum minor.The incidence of rat-bite fever is highest in urban areas with poor sanitation where the rat population is high, however in recent times cases have also been attributed to occupational contact with rodents such as pet shop employees or laboratory workers or through pet ownership.
The other type of infection caused by Spirillum minus is more common in Asia and is also known as Sodoku. [1] The initial non-specific presentation of the disease and hurdles in culturing the causative microorganism are at times responsible for a delay or failure in the diagnosis of the disease.
