"Identificaciòn de leptospira SSP mètodos diagnòsticos directos e indirectos asociadas a las caracterìsticas individuales de los cerdos del centro de faenamiento municipal Portoviejo".

Abstract

Leptospirosis is considered a re-emerging disease, of worldwide distribution caused by bacteria of the genus Leptospira spp. It affects domestic animals; rodents and humans, whose organs most affected are the kidneys and the genital tract. The present research aimed to identify the presence of Leptospira by direct and indirect diagnostic methods, in pigs from the Portoviejo Municipal Slaughter Center, evaluating the individual characteristics associated with positivity to the two diagnostic tests, the methodology used was a systematic random sampling during the months of January, February and March of the year 2021; Among the results found, a prevalence of 10.3% of exposure to Leptospira was observed through the Microscopic Agglutination Test (MAT) composed of a diagnostic battery of 5 serovars (Sejroe, Tarassovi, Hardjo, Bataviae and Wolffii) and 47.68% prevalence of leptospira infection using Dark Field Microscopy (DFM), it was possible to identify the non-existence of association between positivity both to serology and to dark field with the individual characteristics evaluated (sex and origin of the animals slaughtered), with these results we can indicate that leptospira is distributed in the same way in pigs of different localities and sex of the country that are slaughtered in the CFMP. Besides, it is recommended to promote the execution of laboratory tests on the animals, at the farm and farm level in order to determine the prevalence of animals exposed and / or infected with Leptospira ssp and establish the risks for both the animal population and health public.
