TOXOPLASMIC ENCEPHALOMYELITIS

Toxoplasmic Encephalomyelitis

1. Infected material from the brain and spinal cord of an infant suffering from a recently recognized form of granulomatous encephalomyelitis was inoculated into rabbits and mice and produced an experimental disease which was readily transmissible in series. 2. A parasite identical with that in the lesions of the human case was found in the lesions of the experimental animals. 3. The morphology...

HLA antigens and toxoplasmic retinochoroiditis.

HLA (Human Leukocyte-A) antigens of 20 patients with toxoplasmic retinochoroiditis were determined by the standard microlymphocyte cytotoxicity test to see if these patients have different immunogenetic backgrounds from the normal controls. The results showed that there were no significant differences between the patients and the normal controls.

Toxoplasmic lymphadenitis--a clinicopathological study.

Forty-three cases of toxoplasmic lymphadenitis were studied. They constituted 0.5% of all lymph node biopsies and 4.2% of reactive lymphadenitis. The histological findings supporting a diagnosis of toxoplasmosis were correlated with serological studies. The condition primarily affects young men, causing cervical lymph node enlargement and varying degrees of fatigue, malaise, cough and fever. It...

[Hemophagocytic syndrome and toxoplasmic primo-infection].

Hemophagocytic syndrome (HPS) is a clinical entity that combines the clinical, biological and histological symptoms. The physiopathological mechanism involves the interaction between T lymphocytes/NK cells and macrophages, at the origin of an uncontrolled activation of the macrophages. The consequence is a hemophagocytosis extending to numerous organs, preferentially bone marrow. Clinical sympt...
