Disseminated infection with Conidiobolus incongruus.

The first fatal case of disseminated infection due to Conidiobolus incongruus is reported. The patient presented with a subcutaneous mass, febrility, weight loss, cough and hemoptysis. Histological examination of skin and subcutaneous tissue, lung, lymph nodes, esophagus, liver and jejunum showed a granulomatous reaction with bright eosinophilic amorphous material and broad hyphae.

[Ecology of opportunistic fungi].

As most of the pathogenic fungi, opportunistic fungi have a saprophytic life in the soil. The knowledge of their life in natural conditions may allow to avoid their proliferation in the vicinity of man. Examples of ecology were taken among Aspergilli and mycetoma-inducing fungi.

[Mycetoma in Somalia - results of a survey done from 1959 to 1964].

The Pasteur Institute studied 103 mycetoma patients in Somalia between 1959 and 1964. Grains were seen in 94 of them and this, added to cultural features, allowed the diagnosis of 60 pathogens as follows: 44 Madurella mycetomi, 1 Leptosphaeria senegalensis, 7 Pyrenochaeta romeroi (or Madurella grisea), 3 Allescheria boydii, 1 Fusarium sp., 3 Neotestudina (Zopfia) rosatii, and 1 unidentified; 34 were actinomycetes: 24 Streptomyces somaliensis, 4 Actinomadura madurae, 3 A.

[Purification of a protein characteristic of pathogenic strains of "Beauveria tenella" (author's transl)].

Purification of the protein which in immunoelectrophoresis is responsible for the precipitation are characteristic of the pathogenic strains, can easily be obtained by isoelectrofocalisation: two protein fractions are isolated. These differ in their isoelectric points and in their relative electrophoretic migration coefficients in polyacrylamide gel, but exhibit the same antigenic specificity.
