Extremely low viral reservoir in treated chronically HIV-1-infected individuals.

Background: Small viral reservoirs are found predominantly in HIV-1 controllers and individuals treated during acute/early HIV-1 infection. However, other HIV individuals could naturally also harbour low viral reservoirs.

Methods: We screened 451 HIV-1-infected treated-individuals with suppressed plasma viremia for at least 3 years and stored cryopreserved peripheral blood mononuclear cells (PBMCs).

[Serologic diagnosis of Mycoplasma pneumoniae infections].

Mycoplasma pneumoniae is a human pathogen with worldwide distribution. This microorganism is a common cause (10-30%) of community-acquired pneumonia, also called primary atypical pneumonia because of the spectrum of clinical and radiological findings. The immune response is mainly based on rapid antibody production against peptide and glycolipid antigens derived from this microorganism.
