Serological studies of British leptospiral isolates of the Sejroe serogroup: III. The distribution of leptospires of the Sejroe serogroup in the British Isles

Abstract

SUMMARYSome 94 strains of leptospires belonging to the Sejroe serogroup isolated in the British Isles were identified to the serovar level using specific factor sera.Seventy strains were identified as Leptospira interrogans serovar hardjo, 66 from cattle, 2 from pigs and 1 each from a sheep foetus and a human.Twenty-four strains were identified as L. interrogans serovar saxkoebing, most strains were isolated from either wood mice, bank or field voles but strains were also isolated from badgers, a fox and a dog.

Infections of swine caused by Leptospira serovars of serogroup Sejroe - possibilities of recognition with the use of PCR

“…Some reports from the United Kingdom (12,14,17,18) and the United States (2) indicate the Hardjo serovar, belonging to serogroup Sejroe, as an important cause of leptospiral infections in swine (11). Hardjo, antigenically included in one serogroup, is genetically divided into the Hardjo-prajitno type belonging to species L. interrogans sensu stricto and the Hardjobovis type belonging to species L. borgpetersenii (5).…”

“…Icterohaemorrhagiae, Grippotyphosa, Canicola, and others are less often mentioned serovars (11). The infections caused by serovars from the Sejroe serogroup were reported in Germany (3), the U.K. (14,17,18), Hungary (13), Romania (8), and Russia (19) among other countries. Serological monitoring of leptospirosis in swine herds, which has been extensive for many years across Poland, indicated a relatively high percentage of animals presenting titres to the Sejroe serogroup (26)(27)(28).…”
