[Listeriosis and pregnancy].

Listeria monocytogenes is a ubiquitous Gram-positive bacillus widespread in nature. It is responsible for febrile abortion and encephalitis in cattle. It survives and multiplies at 4°C and does not alter the taste of food.

Disseminated toxoplasmosis in non-allografted patients with hematologic malignancies: report of two cases and literature review.

Toxoplasmosis can be a severe opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS), and also among solid organ transplant and allogeneic hematopoietic stem cell transplant (HSCT) patients. Patients with low-grade or chronic hematologic malignancies are treated with increasing immunosuppressive regimens and, therefore, represent an emerging population at risk for opportunistic diseases. We report here two cases of disseminated toxoplasmosis occurring in non-allografted hematologic patients with chronic lymphoproliferations.

Disseminated nontuberculous infections with Mycobacterium genavense during sarcoidosis.

Sarcoidosis is a chronic disease characterised by the development and accumulation of granulomas in multiple organs. We report two observations of disseminated Mycobacterium genavense infection in patients with proven sarcoidosis. High fever and abdominal pain appeared at 8 and 18 months following the initiation of immunosuppressive therapy.

[Listeriosis, a rare but severe foodborne infection].

Listeria monocytogenes is a Gram-positive bacillus widespread in nature and responsible for human and animal infections. Listeriosis is a severe and rare infection transmitted orally and vertically, frequently in the context of an underlying immunosuppression. L.
