Protective activity of glycolipid antigen against infection by Leptospira interrogans serovar canicola.

A protective glycolipid antigen (PAg) was extracted from Leptospira interrogans serovar canicola with chloroform/methanol/water (1:2:0.8, by vol.) and partially purified by silica gel column chromatography. The PAg elicited a protective response in hamsters and in cyclophosphamide-treated mice subsequently challenged with homologous Leptospira. The PAg band was detected as a single smear-like band, corresponding to a protein of 23-30 kDa, by silver-staining in SDS-PAGE. In immunoblots, this band reacted with a monoclonal antibody, A5, which agglutinated serovar canicola and recognized a serovar-specific antigen. Furthermore, the PAg did not migrate on silica gel TLC, but was detected at the origin as a ninhydrin- and naphthol-positive spot. This suggests that PAg is a hydrophilic molecule with a carbohydrate chain that contains amino groups, possibly as amino sugars.

Leptospira icterohaemorrhagiae infection presenting as acute renal failure.

The features of leptospiral infection should be sought in all cases of acute renal failure since management depends on the recognition of the clinical syndrome and serological confirmation is usually delayed. Hepatic and renal involvement is usual but renal failure without significant derangement of liver function is described.

Studies on equine recurrent uveitis. II: The role of infection with Leptospira interrogans serovar pomona.

An enzyme linked immunosorbent assay was developed for the detection of immunoglobulin class specific antibodies to Leptospira interrogans serovar pomona in the serum and aqueous humor of horses. Serum antibody was also assayed by microscopic agglutination tests. Although higher levels of antibody were found in sera from horses with signs of uveitis, the association was not statistically significant. Antibodies to pomona were detected in the aqueous of 12 eyes from the 101 horses sampled at a slaughterhouse, and in most instances, a comparison of the aqueous/serum antibody level with that of the total aqueous/serum IgG level indicated intraocular antibody synthesis. Antibodies were also found in 4 aqueous (or vitreous) samples out of 9 obtained from horses with clinically documented uveitis and the above comparison again indicated intraocular antibody synthesis. The data point to an important role for pomona as an etiology of equine recurrent uveitis but also emphasize that the initiating cause for this disease is often obscure in that association with leptospirosis cannot be shown in many instances.
