[The rapid ELISA method for detection of orthopoxviruses].

Introduction: Following the successful eradication of smallpox, mass vaccination against this disease was discontinued in 1980. The unvaccinated population continues to be at risk of infection due to military use of variola virus or exposure to monkeypox virus in Africa and non-endemic areas. In cases of these diseases, rapid diagnosis is of great importance, since the promptness and effectiveness of therapeutic and quarantine measures depend on it.

Evaluation of Rapid Dot-Immunoassay for Detection Orthopoxviruses Using Laboratory-Grown Viruses and Animal's Clinical Specimens.

The aim of the work was an experimental evaluation of the characteristics of the kit for the rapid immunochemical detection of orthopoxviruses (OPV). The kit is based on the method of one-stage dot-immunoassay on flat protein arrays using gold conjugates and a silver developer. Rabbit polyclonal antibodies against the vaccinia virus were used as capture and detection reagents.

Rapid protocol of dot-immunnoassay for orthopoxviruses detection.

The aim of the work was to create a sensitive and fast immunochemical test for the detection of orthopoxviruses (OPXV) in the "point of care" format. This work presents the results of the comparative evaluation of a single-stage (rapid version) and two-stage protocol of dot-immunoassay based on plane protein array for detection of vaccinia virus (VACV), cowpoxvirus (CPXV) and ectromelia virus (ECTV) in viral culture materials with different degrees of purification. It has been established that rabbit polyclonal VACV-antibodies can be used in a one-stage dot-analysis, both as a capture agent immobilized on a substrate and as a detection reagent bound with colloidal gold particles.

[Rapid immunochemical method for the detection of orthopoxviruses (Orthopoxvirus, Chordopoxvirinae, Poxviridae).].

Introduction: The abolition of smallpox vaccination has led to the disappearance of population immunity to pox viruses. However, the threat of infection by pathogenic orthopoxviruses persists and determines the need to develop sensitive and operational methods for indicating pathogens.

Objectives: Development of a sensitive, fast and easy-to-use immunochemical test for the detection of orthopoxviruses in the «point of care» format.

Multiplex method for initial complex testing of antibodies to blood transmitted diseases agents.

Initial screening of donors and population at high risk of infection with blood transmitted diseases involves a number of analyses using monospesific diagnostic systems, and therefore is expensive labor- and time-consuming process. The goal of this work is to construct a multiplex test enabling to carry out rapid initial complex testing at a low price. The paper describes a kit making it possible to detect simultaneously antibodies to six agents of the most significant blood transmitted diseases: HIV virus, hepatitis B and C viruses, cytomegalovirus, T.
