“…Available data concerning the occurrence of infections in swine caused by leptospires from the Sejroe serogroup have recently been based on serological findings (3,15) and were earlier based on results of isolation (2,4,8,13,14,17). Isolated strains were identified as the Saxkoebing (4), Hardjo (2,14,17), or other serovars.…”

The aim of this study was to confirm the presence of leptospires from the Sejroe serogroup in aborting seropositive sows and to identify which serovars of this serogroup are responsible for the infection. Serum and urine samples from 20 aborting sows, reared in five farms infected with the Sejroe serogroup, were submitted for examination. Serum samples were examined by the microscopic agglutination test (MAT) and urine samples by polymerase chain reaction (PCR) with primer sets specific for genus Leptospira, species L. borgpetersenii, the Sejroe serogroup, and the Hardjo-bovis genotype. All the examined serum samples showed titres specific to the Sejroe serogroup, ranging from 100 to 6400. PCR indicated the presence of Leptospira genus-specific DNA sequences in all urine samples examined. DNA sequences specific for both L. borgpetersenii and the Sejroe serogroup were found in 12 of these samples. Additionally, the sequences specific only for L. borgpetersenii were found in five urine samples and sequences for the Sejroe serogroup in two samples. The DNA sequence specific for the Hardjo-bovis genotype was not found in the urine samples. PCR confirmed the results of the MAT, displayed the presence of Leptospira sp. DNA in the urine of all the sows examined, proved the affinity of the detected leptospires to the Sejroe serogroup or at least to L. borgpetersenii, and excluded the Hardjo serovar as the reason for the infections described in the sows.

“…In spite of high prevalence of swine demonstrating titres to serovar Sejroe, clinical symptoms of leptospirosis (including abortions) are not often observed in these animals. Infections with this serovar in swine were noted in Europe before (Brandis 1956, Combiesco et al 1958, Ellis 2006. However, recently there are not many reports describing an occurrence of higher percentage of positive reactions with serovar Sejroe in serological screenings of swine herds in Europe end over the world (Wasiński 2005, 2007, Jung et al 2009).…”

Swine are one of significant reservoirs and sources of Leptospira infections for man. Serological screenings help to effectively control the epidemiological situation in swine herds and to prevent transmission of Leptospira from animals to man. The purpose of this study was to investigate, by the use of serological methods, the prevalence of infections caused by selected Leptospira serogroups in swine population in Poland.A total of 7112 swine serum samples were examined. The samples were collected from January to October 2008 and came from 280 counties situated in all 16 provinces of Poland. All sera were examined preliminary by enzyme-linked immunosorbent assay (ELISA) using heat-stable antigenic preparation. The samples positive or doubtful in ELISA were investigated by microscopic agglutination test (MAT) with use of serovars Icterohaemorrhagiae, Pomona, Canicola, Sejroe, Tarassovi and Grippotyphosa.Of the collected sera examined by ELISA 73 (1.02%) samples were positive, 85 (1.20%) -doubtful and 6954 -negative. Among ELISA-positive and doubtful sera 64 samples (coming from 14 provinces) were recognized in MAT as positive. Among MAT positive samples 42.19% of sera demonstrated titres with serovar Pomona, 32.81% -with Sejroe, 14.06% -with Icterohaemorrhagiae, 6.25% -with Tarassovi, 3.13% -with Grippotyphosa and 1.56% with Canicola.
