Recent observations on leptospirosis in Northern Ireland and their bearing on current diagnostic methods

Journal of Clinical Pathology

An investigation was undertaken to assess the present importance of leptospiral infections in Northern Ireland, and in particular to look for evidence of infection by leptospiral serotypes other than L. icterohaemorrhagiae and L. canicola. Blood samples from 335 patients, sent to the laboratory for a variety of tests, were examined. After initial screening with five groups of pooled antigens, tests for leptospiral agglutinins were completed with formolized antigens prepared from 13 different serotypes. In seven patients a diagnosis of acute leptospirosis was made while nine others showed serological evidence of previous leptospiral infection. Attempts to isolate leptospirae by culture from 29 blood samples were unsuccessful. The serological results indicate that two additional leptospiral serotypes, namely L. ballum and L. bratislava, are causing human infection in Northern Ireland, and presumably also in other parts of the British Isles. Some clinical and epidemiological features associated with different types of leptospiral infection are described. It is stressed that leptospirosis is essentially a febrile illness, that meningeal symptoms are common, and that (contrary to popular belief) jaundice is by no means a constant oc...Continue Reading

Antibodies: Agglutination

Antibody-mediated agglutination is the clumping of cells in the presence of antibody, which binds multiple cells together. This enhances the clearance of pathogens. Find the latest research on antibody-mediated agglutination here.
