Abstract
A serologic survey was made of the prevalence of common leptospiral infections in horses in California [USA]. A total of 465 serums were tested, using the microscopic agglutination method, against 5 leptospiral serotypes: Leptospira pomona, L. icterohaemorrhagiae, L. canicola, L. grippotyphosa and L. 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.
