Epidemiological and immunochemical parameters of monoclonal plasma cell dyscrasias of 2121 cases in Algeria.

Background: Plasma cell dyscrasias (PCD) are a heterogeneous group of diseases characterized by the expansion of monoclonal bone marrow plasma cells that produce a monoclonal immunoglobulin (M-component).

Purpose: This is a retrospective study that describes the epidemiological, immunochemical features and etiology of monoclonal gammopathies diagnosed between 1998 and 2016 in the Teaching Hospital Beni-Messous of Algiers.

Patients And Methods: 2121 cases of monoclonal gammopathies (MG) were collected during this period.

Diversity of the Genes Implicated in Algerian Patients Affected by Usher Syndrome.

Usher syndrome (USH) is an autosomal recessive disorder characterized by a dual sensory impairment affecting hearing and vision. USH is clinically and genetically heterogeneous. Ten different causal genes have been reported.

Reprint of: Serotyping and antibiotic susceptibility of Streptococcus pneumoniae strains isolated in Algeria from 2001 to 2010.

Introduction: Pneumococcal infections are a major public health problem because of the virulence of this bacterium and its ability to develop resistance.

Material And Method: Two hundred and ninety-four strains of Streptococcus pneumoniae were isolated from sterile (56.8%) and non-sterile samples (43.

[Listeria serotyping].

Serotyping of Listeria has contributed to bring to light on the origin of outbreaks listeriosis; on the other hand, it is also an additional expression for the identification of Listeria genus. In order to get better in this field, we have produced five factors sera: I, I/II, V/VI, VI, VII.
