title: Serologic survey of leptospiral antibodies in horses in California.
abstract: A serologic survey was made of the prevalence of common leptospiral infections in horses in California. A total of 465 serums were tested, using the microscopic agglutination method, against 5 leptospiral serotypes: Leptospira pomona, Leptospira icterohaemorrhagiae, Leptospira canicola, Leptospira grippotyphosa, and Leptospira hardjo. Of the serums tested, 127 (27.30%) were positive against 1 or more of the leptospires, with percentage distribution among the reactors as follows: L pomona, 12.47%; L icterohaemorrhagiae, 10.32%; L canicola, 3.22%; L grippotyphosa, 0.86%; and L hardjo, 0.43%. The prevalence of reactors to leptospiral antigens did not differ with the age or sex of the animals.
