Abstract

The agglutination-lysis test for leptospiral infection has been applied to 2,773 samples of porcine sera that were obtained from various parts of Scotland, England and Northern Ireland. Antibodies to three leptospiral serotypes have been detected in 1003 (36.2 por cent.) of those sera. Evidence of infection was forthcoming as follows; to Lepto. Canicola in 79 specimns, to Lepto. Icterohaemorrhagiae in 412 specimens and to Lepto. Pomona in 206 specimens. In 306 samples positive reactions were observed with more than one serologically distinct antigen. In case of Lepto. Canicola the concentration of antibodies varied from 1;10 to 1;30,000 Titres to Lepto. Ictero haemorrhagiae ranged from 1;10 to 1;10,000. Lysis of Lepto. Pomona was observed in dilutions of serum of up to 1;1000. Not any specimen was found to contain antibodies to either Lepto. Grippotyphosa or Lepto. hycs. Infection by Lepto. canicola was detected by serological means in five piggeries in the West of Scotland and later confirmed confirmed/ by the isolation of the organism from the renal tissues of pigs that were collected from three of those farms. Culture No. 1078 was recovered soon after canicola fever had been diagnosed in a worker employed on the farm. In a study of the survival in pig kidney of Lepto. canicola it emerged that the organism could survive for twelve days in naturally infected material stored at 0-4
