| Popis: | Percentage of serological positivity examined in 4205 blood sera by serological method microscopic agglutination test (MAT) on the hinterland territory of our laboratory (East Bohemia; 1999-2003) was 0.38-4.7 %. By the PCR method for detection of DNA of pathogenic leptospires (L. interrogans, L. borgpetersenii and L. kirschneri) from 57 samples of different biological materials from patients with fever of unknown etiology positive results were obtained in 4 specimens (7 %; 3 samples of urine and 1 sample of blood). This method was shown to distinguish between pathogenic and nonpathogenic strains and can detect 2.5-10 cells per mL of biological material. As an important presumption of successful detection of pathogenic leptospires a correct collecting of blood, urine samples or liquor is required before starting antibody therapy. The PCR method possesses a clear advantage over other methods, such as MAT, which relies on the detection of antibodies the presence of which cannot be detected until days after infection. |
