Resumen
The intensity and duration of passive immunity against swine leptospirosis were investigated by the microscopic agglutination test and in vitro leptospira growth inhibition. Twenty-one females at first parturition were divided into three groups: Group A (n = 08): received two doses with 30 days interval of the commercial anti-leptospira bacterin A. Group B (n = 06) received two doses with 30 days interval of the commercial anti-leptospira bacterin B and Group C (n = 07) was the control. In all groups the colostrums were collected. Blood collection of piglets was performed in four different ages. Agglutinin antibodies were equally detected in sera and colostrums for serovars Canicola, Grippotyphosa, Copenhageni, Icterohaemorrhagiae and Pomona (Group A) and Canicola, Copenhageni, Icterohaemorrhagiae, Pomona and Hardjo (Group 13). Mean neutralizing antibodies titers were low. Passive immunity was low duration. (C) 2007 Elsevier Ltd. All rights reserved.
