ABSTRACT

Background:

Leptospirosis is a worldwide disease that impacts health, welfare and animal production. Manifestations inswine range from subclinical to severe cases of reproductive failure, generating abortions, embryonic resorption, litters withfew piglets, and piglets born weak or dead, which causes great economic losses. Tropical conditions in Colombia favortransmission and maintenance of Leptospira, highlighting the importance of implementing direct diagnostic techniquessuch as isolation through culture to reach a definitive diagnosis. The objective of the present study was to relate reproductive indicators behavior with the presence of Leptospira spp. in two pig farms in Cundinamarca, Colombia.Materials, Methods &

Results:

Sows in reproductive stage in two pig farms were selected. A clinical examination of theanimals was performed to demonstrate the presence of signs suggestive of Leptospirosis, also the sow records were reviewed to find reports of any of these clinical manifestations, and the average of the reproductive indicators was calculatedto set which were altered in the sows. Blood and urine samples were obtained and analyzed by microscopic agglutinationtest (MAT) and isolation through culture, respectively. Among the altered reproductive indicators were identified totalpigs born (TPB) in 72.5%, stillbirths (SB) by 70%, mummified pigs (MUM) in a 52.5%, pre-weaning death (PWD) by40% and the 24 h mortality (M24h) in the 20%. The 77.5% of the sows were positive by MAT. The predominant serovarsof Leptospira spp. included Grippotyphosa (67.5%), Canicola (22.5%), Icterohaemorrhagiae (20%), Hardjo (17.5%) andPomona (12.5%). The bacterium was isolated in 32.5% of the analyzed urine samples. There is increased risk of alteration in the indicators M24h (1.27), TPB (1.08), SB (1.15) and MUM (1.27) with the presence of...
