Frequency of Leptospira spp in pigs from commercial farms and backyard breeding slaughtered in two abattoirs of Lima

Descripción del Articulo

The objective of this study was to determine the frequency of antibodies against Leptospira spp in pigs reared in five well-managed farms (n=163) and from 11 backyard breeding (n=133) owners in the Lima valley, Peru. Blood samples (n=296) were collected in two slaughterhouses for antibody detection...

Blood samples (n=296) were collected in two slaughterhouses for antibody detection against eight serovars of Leptospira by microaglutination test. The 85.8 ± 3.9% (254/296) of samples had antibodies against one or more serovars of Leptospira. The 89.6 ± 4.7% (146/163) and 82.1 ± 6.5% (108/133) of samples from well-managed farms and from backyard breeding pigs showed antibodies against Leptospira spp. The serovars icterohaemorrhagiae, pomona, and georgia were the most frequently detected in both groups of pigs. No antibodies were detected against serovars bratislava and grippothyphosa. Antibody titres ranged from 100 to 400, being the highest titles (800 to 1600) detected more frequently in backyard breeding pigs. Serovars icterohaemorrhagiae and pomona were the most common mixed infections found for both type of breeding systems. There were no association between antibodies against Leptospira and type of pig breeding system.El objetivo del estudio fue determinar la frecuencia de anticuerpos contra Leptospira spp en porcinos provenientes de crianza tecnificada (5 granjas, n=163) y de traspatio (11 criaderos, n=133) del valle de Lima. Se colectaron muestras de sangre de porcinos (n=296) durante el beneficio en dos mataderos de la ciudad de Lima, para la detección de anticuerpos contra ocho serovares de Leptospira mediante la prueba de microaglutinación. El 85.8 ± 3.9% (254/296) de las muestras fue positivo a uno o más serovares de Leptospira. El 89.6 ± 4.7% (146/163) y el 82.1 ± 6.5% (108/133) de las muestras de porcinos de crianza tecnificada y de traspatio, respectivamente, tuvieron anticuerpos contra Leptospira. Los serovares icterohaemorrhagiae, pomona y georgia fueron los más frecuentes en ambos tipos de crianza. No se detectaron anticuerpos contra los serovares bratislava y grippothyphosa. Los títulos de anticuerpos tuvieron un rango entre 100 a 400 en ambos tipos de crianza, pero títulos de anticuerpos de 800 a 1600 fueron detectados con mayor frecuencia en animales de traspatio. La combinación icterohaemorrhagiae y pomona fue la más común en ambos tipos de crianza. No hubo asociación entre la presencia de anticuerpos contra Leptospira y la procedencia de los porcinos evaluados.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2012-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/90510.15381/rivep.v23i2.905Revista de Investigaciones Veterinarias del Perú; Vol 23 No 2 (2012); 240-245Revista de Investigaciones Veterinarias del Perú; Vol. 23 Núm. 2 (2012); 240-2451682-34191609-9117reponame:Revista UNMSM - Revista de Investigaciones Veterinarias del Perúinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/905/730Derechos de autor 2012 Luis Anampa V., Hermelinda Rivera G., Néstor Falcón P., Mariluz Arainga R., Mercy Ramírez V.http://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2021-06-01T18:05:56Zmail@mail.com -
