The aim of this study was to evaluate the incidence of leptospirosis in Pardubice and Hradec Králové regions and a part of Vysočina region in 2002-2009. A group of patients was statistically analyzed and the incidence rates of leptospirosis in individual months and years were calculated.A group of 4,813 patients with suspected leptospirosis from Pardubice and Hradec Králové regions and a part of Vysočina region were examinated in our centre in 2002-2009. A total of 5,366 biological samples were studied. From 4,625 blood samples, 3,958 were examinated with the serological microagglutination-lysis method and the remaining 667 with the PCR method.From 4,813 patients suspected to have leptospirosis, 89 were found to be leptospirosis-positive. Leptospirosis was diagnosed in 63 males (70.7 %) a 26 females (29.3 %); the mean age were 39.52 ± 17.67 years in males and 46.85 ± 18.34 years in females; the mean age men + women was 41.66 ± 18.13 years (range 3-78 years). Most positive male patients (n = 28) were in 26-45 age group; the findings were similar in females (n = 10). The highest number of leptospirosis cases was noted in 2005. Most frequently, infection caused by pathogenic leptospires was diagnosed in November.The incidence rates of leptospirosis in Pardubice and Hradec Králové regions and a part of Vysočina region in 2002-2009 (with the exception of 2008) exceeded the overall reported levels 0.4/100,000 population.

The aim of this study was to evaluate diagnostic sensitivity and specificity of the SERION ELISA classic IgM and SERION ELISA classic IgG kits and to confirm the results by the microagglutination test (MAT).A total of 45 blood serum samples from 45 patients, 30 from males and 15 from females (mean age 44.24 ± 15.56 range 19-82 year), were included in our study. Blood serum samples were examined using the ELISA and MAT methods and diagnostic sensitivity and specificity of both methods were calculated.The MAT was shown to have 100 % diagnostic sensitivity and specificity. The ELISA kits for detecting IgM and IgG antibodies against pathogenic leptospires had diagnostic sensitivity of 100 % and diagnostic specificity of 88.6 % and 54.3 %, respectively.The above results suggest that the MAT with diagnostic sensitivity and specificity of 100 % remains the gold standard for detection of specific antibodies against pathogenic leptospires. The diagnostic sensitivity of both ELISA kits is high but due to their low diagnostic specificity, especially in the case of IgG antibodies, the kits are inappropriate for use in routine clinical practice.
