[The occurrence of infections caused by Francisella tularensis in humans in Poland and laboratory diagnosis of tularemia].

Tularemia is a serious infectious zoonotic disease, caused by Gram-negative bacterium Francisella tularensis. Natural reservoir of infection are small mammals such a mice, voles, squirrels and rabbits. Transmission to humans occurs through contact with infected animals or contaminated environments, or through arthropod vectors.

[Enzyme-linked immunosorbent assay (ELISA) for detection of antibodies to Salmonella Typhi lipopolysaccharide O and capsular polysaccharide Vi antigens in persons from outbreak of typhoid fever].

Introduction: The laboratory diagnosis of typhoid fever is dependent upon either isolation of S. Typhi from a clinical sample or the detection of raised titers of serum antibodies in the Widal test or the passive hemagglutination assay (PHA). In this study we evaluated the usefulness of ELISA for detection of antibodies to S.

[Seroprevalence of Mycoplasma pneumoniae in Poland in 2008-2013].

Introduction: Mycoplasma pneumoniae is a common causative agent of tracheobronchitis and atypical pneumonia, mainly in children and adolescents. The infections are often seen as epidemics occurring in autumn-winter seasons at intervals of 4-7 years. Epidemiological studies showed that M.

[Serodiagnosis of clinical infections caused by Mycoplasma pneumoniae in Poland in 1970-2010].

The aim of the study was evaluation of the reliability of serodiagnosis of mycoplasmosis in Poland after replaced of classical assays, as complement fixation test (CFT) and immunoelectroprecipitation test (IEPT), by the ELISA method. The data were obtained from National Public Health Institute in Warsaw (NPHI), which receives quarterly reports of serologically confirmed infection from Sanitary and Epidemiological Stations through the country. Previously, from the 1970 to 1999 the serodiagnosis in Poland was performed only by uniform CFT using the same M.

[Application of enzyme linked immunosorbent assay (ELISA) for diagnosis of antibodies to lipopolysaccharide of Klebsiella rhinoscleromatis in patients with rhinoscleroma].

The ELISA were performed on polystyrene microtiter plates (Nunc, MaxiSorp) coated with LPS (2a antigen) at the final concentration of 10 microg/ml. The antigen was extracted from Klebsiella rhinoscleromatis Rh32 by the trichloroacetic acid and separated by ethanol (Boivin method). The antibodies against the LPS were detected by ELISA in serum samples collected from 65 patients suspected in clinical investigation for rhinoscleroma in Poland from 1970 to 2009.
