Determinación de la frecuencia de Leptospirosis Porcina en el centro de faenamiento de la parroquia Malacatos de la provincia de Loja

Porcine leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira, with widespread global distribution and higher prevalence in tropical and subtropical regions. This study was conducted at the slaughter center of Malacatos Parish, Loja Province (Ecuador), aiming to determine the presence of antibodies against Leptospira spp. and to identify pathogenic Leptospira in porcine urine. A quantitative approach was adopted, with a cross-sectional observational design. Blood and urine samples were collected from 90 pigs destined for slaughter, without distinction of age, sex, or origin, using microscopic agglutination tests (MAT) and conventional PCR. Antibodies with titers ranging from 1/100 to 1/400 against five Leptospira serovars—Bratislava, Pomona, Icterohaemorrhagiae, Copenhageni, and Canicola—were found in 11.11% of the pigs; no pathogenic Leptospira was detected in urine samples. Coagglutination with a titer of 1/100 was found in four serovars: Bratislava, Pomona, Icterohaemorrhagiae, and Canicola. No significant differences were found in seropositivity with respect to the animals' age, sex, or origin. This study reveals the circulation of Leptospira spp. in pigs from Malacatos, representing an important health issue in the region’s pig production and a potential public health risk due to zoonotic transmission potential.
