CISNEROS PUEBLA, Miguel Ángel et al. Serología diagnóstica de leptospirosis porcina en México 1995-2000. Rev Cubana Med Trop [online]. 2002, vol.54, n.1, pp. 28-31. ISSN 1561-3054.

Results obtained from sample testing of 1 970 swines from a number of Mexican farms were analyzed. Such samples had been received in the Leptospira Lab of Universidad Autonoma Metropolitana de Xochimilco from 1995 to 2000. Sera with titers equal to or higher than 1:1000 were considered positive; 39,8% of the animals were seropositive (784) and the most frequent serovarieties were bratislava, 22,5%; icterohaemorrhagiae strain Palo Alto, 14,5%; portland vere strain Sinaloa ACR, 13,8%; icterohaemorrhagiae, 11,1%; grippotyphosa, 8,9%; hardjo strain H89,7,2%; tarassovi,7,1%; panama, 5,8%, pomona and hardjo, 5,1%; wolffi, 3%; shermani, 2,4%; pyrogenes, 1,2%; canicola, 0,8%; hebdomadis, 0,5%. The bratislava serovariety has been reported as the cause of reproductive failure in several countries and it holds the first place in serological studies. Therefore, the present paper provides information for stating that this is one of the most significant serovarieties in Mexico.
