title: [Histoplasmosis - an unusual African souvenir].
abstract: METHODS
  A 24-year-old woman (student of biology) was part of a study group in Uganda. She developed fever and headache, which was empirically treated as malaria. After she had returned to Switzerland, a chest x-ray showed bilateral miliary nodular infiltrates. In assumption of an atypical pneumonia, she was treated with levofloxacin, although without success. On admission, she was in a bad general condition and was markedly dyspneic. Rales were heard over both lungs.
  
  
  METHODS
  CRP, liver enzymes and LDH were elevated. A lung function test revealed a marked impairment of the diffusion capacity. The chest x-ray showed a progression of the lung infiltrates. The informal medical data exchange among the group members by a virtual social network abbreviated our diagnostic workup substantially, since we heard that histoplasmosis had been assumed in another group member. It turned out that the affected persons had visited a colony of bats living in a cave inside the trunk of a tree. Antibodies against Histoplasma capsulatum were positive.
  
  
  METHODS
  We began a treatment with itraconazole. The condition improved gradually; chest x-ray and lung function normalized after the 8 week treatment.
  
  
  CONCLUSIONS
  Histoplasmosis with such a severe course is rare in immunocompetent humans, which indicates that the inoculum must have been very high. Soil contaminated with bats guano favours the proliferation of Histoplasma capsulatum. Our case is also an illustration of how the widespread use of electronic media can sometimes facilitate our work.
