[Benign inoculation lymphoreticulosis or cat-scratch disease].

Discovered in 1950-51 by two great parisian medical teams, inoculation lymphoreticulosis, also called cat's scratch disease, is locoregional adenitis whose aetiology is imperfectly determined. Following, often bu not always, cat's scratch, it may evolve to suppuration. Pus is always aseptic. Attributed to Bedsonia's family micro-organism, no cultivation was possible up to date. Evolution is as a rule favourable, but disease is poorly accessible to tetracycline family's antibiotics. Diagnosis is possible by intradermoreaction. The antigen used is tyndallised pus of homologous infection. The role of the cat, still healthy, has not yet been explained.

[Anatomic and bacteriological study of surgically extracted valves in patients with bacterial endocarditis].

We studied 64 cases of bacterial endocarditis which required heart surgery for hemodynamic defects and/or failure of the antibiotic therapy. We performed a bacteriologic and histologic investigation of the removed valves. The organisms were evidenced through culture and specific stainings. According to the different organisms we evaluated the best duration of antibiotic therapy to achieved sterilization, and suggest a helpful medical and surgical treatment for the bacterial endocarditis.

[Morphological diagnosis of Pneumocystis carinii].

Pneumocystis carinii pneumonia can only be diagnosed once the microorganism is demonstrated. The authors review and illustrate various staining technics, and discuss for each of them specific advantages. All samples must by systematically examined both by phase contrast microscopy and by light microscopy after Gomori-Grocott and Gram-Weigert stains. This morphological study is completed by ultrastructural photographs.

[Anatomo-clinical and experimental studies on pneumocystis carinii. Preliminary note].

The authors have been interested over the last year in the detection of pneumocystis carinii in patients with immune deficiencies, whether natural or artificial. After a brief historical and general introduction, they discuss their procedures, the pathological substances available, the staining techniques and the examination of autopsy specimens. They undertook experimental work on this micro-organism, e.g. the development of the germ in immuno-depressed rats and, from this material, numerous varied trials of culture and inoculation in new-born animals, chick embryos and cell cultures. Microphotographs illustrate this work which is still in progress.
