DISTRIBUTION AND FREQUENCY OF BLASTOCYSTIS SP. BY METHODS OF MICROSCOPY AND CULTIVATION IN FAECES OF RESIDENTS OF KHARKOV REGION.

Blastocystis sp. - is the most prevalent anaerobic intestinal protozoan parasite in humans and many animals; from 1 to 2 billion people in the world are colonized by this pathogen. Blastocystis sp.

Seroprevalence of babesiosis in immunocompetent and immunocompromised individuals.

Unlabelled: Interest in Babesia species is gaining an increasing attention as an emerging tick-borne pathogen. Infection is primarily transmitted through Ixodes ticks, and alternatively by blood transfusions from asymptomatic donors.

Aim: The aim of the study was detection of Babesia seroprevalence in different groups of population with the usage of experimental B.

Implementation and analysis of Babesia immunoassay testing.

Unlabelled: Lifelong withdrawal from the donor population of those who have been diagnosed with babesiosis must be used for transmission prevention.

Aim: The aim of the study was a detection of Babesia antibodies level with the usage of experimental Babesia divergens whole-cell slide antigen and commercial B. microti immunofluorescence assay substrate slide (Fuller Laboratories, USA).

Anaplasmosis: experimental immunodeficient state model.

Objective: Introduction: The recently described anaplasmosis infection is widespread but concerns to the insufficiently known group of diseases. The aim of our research is the development of uniform biological model for reproducing of artificial immunodeficient state by experimental anaplasmosis.

Patients And Methods: Materials and methods: Algorithm of experimental anaplasmosis reproducing, consisted of such consecutive stages: 1) artificial forming of the immunodeficient state at nonlinear white mise (Mus musculus L.

Use of Piezoelectric Immunosensors for Detection of Interferon-Gamma Interaction with Specific Antibodies in the Presence of Released-Active Forms of Antibodies to Interferon-Gamma.

In preliminary ELISA studies where released-active forms (RAF) of antibodies (Abs) to interferon-gamma (IFNg) were added to the antigen-antibody system, a statistically significant difference in absorbance signals obtained in their presence in comparison to placebo was observed. A piezoelectric immunosensor assay was developed to support these data and investigate the effects of RAF Abs to IFNg on the specific interaction between Abs to IFNg and IFNg. The experimental conditions were designed and optimal electrode coating, detection circumstances and suitable chaotropic agents for electrode regeneration were selected.
