Presentation
editAssociated conditions
editThere 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
editIt is most frequently caused by Staphylococcus aureus, and less frequently by Pseudomonas aeruginosa, E. coli, Proteus, and Streptococcus, Bacteroides.[1] Risk factors include weak immune system, HIV, alcoholism, and Job syndrome.[1]
Diagnosis
editDiagnosis is by culture of the discharge.[1]
History
editThe 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).[2] In 1919 the bacterial origin of the infection was discovered.
