SpecialtyInfectious disease

Botryomycosis has been known to affect humans, horses, cattle, swine, dogs and cats.

Presentation

Associated conditions

There are only a handful of documented cases of botryomycosis in humans, and its pathogenesis is not completely understood. However, it is usually described in individuals with impaired immunity, or with an underlying disease such as diabetes mellitus, cystic fibrosis or HIV infection.

Causes

Staphylococcus aureus is usually the organism that causes the infection,[2] however it can also be caused by Pseudomonas aeruginosa or several other species of bacteria. The anatomic structure of its lesion is similar to that of actinomycosis and eumycetoma, and its granules resemble the sulfur granules of actinomycosis.

Diagnosis

History

The disease was originally discovered by Otto Bollinger (1843–1909) in 1870, and its name was coined by Sebastiano Rivolta (1832–1893) in 1884. The name refers to its grape-like granules (Gr. botryo = grapes) and the mistakenly implied fungal etiology (Gr. mykes = fungus).[3] In 1919 the bacterial origin of the infection was discovered.

gollark: Totally different.
gollark: Nope!
gollark: Um, anyway, advice:- use CSS- `<i>` is deprecated for some reason so use `<em>`- favor CSS padding/margin instead of `<br>`- indent sanely- please make sure your thing is actually parseable and doesn't contain random opening tags
gollark: I see.
gollark: Also your indentation is really weird, are you using an IDE?
