Terminology
  • The disease was originally discovered by Otto Bollinger in 1870, and its name was coined by Sebastiano Rivolta in 1884
  • The name refers to its grape-like granules (Greek: botryo = grapes) and the mistakenly implied fungal etiology (Greek: mykes = fungus)
  • In 1919 the bacterial origin of the infection was discovered
Etiology
  • Staphylococcus aureus is usually the causative organism, however, it can also be caused by Pseudomona aeroginosa or several other species of bacteria
  • The anatomic structure resembles actinomycosis and mycetoma, and its granules resemble the sulfur granules of actinomycosis
  • It is usually described in individuals with impaired immunity or with an underlying disease such as diabetes mellitus, cystic fibrosis or HIV infection
