ASSOCIATION OF LEPTOSPIRA INFECTION AND REPRODUCTIVE PROBLEMS IN A LARGE SHEEP FARM IN THE CENTRAL HIGHLANDS OF PERu

Descripción del Articulo

The association between leptospiral infection and reproductive problems in ewes from a large sheep enterprise in Junin, Peru, was evaluated in a Case-Control study during the breeding season of 2003. Serum samples from 2-10 year-old ewes with abortion or infertility problems (Case group, n = 220) an...

Serum samples from 2-10 year-old ewes with abortion or infertility problems (Case group, n = 220) and from ewes without reproductive problems (Control group, n = 220) were collected for the detection of antibodies against Leptospira serovar: pomona, hardjo, canicola, icterohaemorrhagiae, grippotyphosa, wolffi, ballum and bratislava by the microscopic agglutination test. The prevalence of Leptospira sp. was 24.8 ± 4.6%, corresponding 28.6 ± 7.0% to the Case group and 20.9 ± 5.9% to the Control group. No statistic association between leptospiral antibodies and reproductive problems was found by the Chi Square test. The highest serological prevalence (42.2%) was recorded for serovar ballum followed by icterohaemorrhagiae (31.2%). Animals with antibodies to more than one serovar of Leptospira were detected.El objetivo del presente estudio fue determinar la asociación entre la infección por Leptospira sp. y la presentación de problemas reproductivos en ovejas de dos localidades de una Sociedad Agrícola de Interés Social (SAIS), en Junín, durante la campaña reproductiva del 2003, a través de un estudio de Caso-Control. Se colectaron muestras de suero de ovejas entre 2 a 10 años de edad que abortaron o que no quedaron gestantes después de uno o dos empadres (grupo Caso: n = 220) y de borregas sin problemas reproductivos (grupo Control: n = 220) para determinar anticuerpos contra Leptospira, serovares pomona, hardjo, canicola, icterohaemorrhagiae, grippotyphosa, wolffi, ballum y bratislava, mediante la técnica de microaglutinación. La frecuencia de Leptospira sp. fue de 24.8 ± 4.6%, correspondiendo al grupo Caso 28.6 ± 7.0% y al grupo Control 20.9 ± 5.9%. No se encontró asociación estadística entre las variables presencia de anticuerpos y problemas reproductivos mediante el análisis de Chi Cuadrado. Los serovares detectados con mayor frecuencia fueron ballum con 42.2% (46/109) seguido por icterohaemorrhagiae con 31.2% (34/109). Se detectó animales con anticuerpos contra más de un serovar de Leptospira.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2009-07-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/57110.15381/rivep.v20i1.571Revista de Investigaciones Veterinarias del Perú; Vol. 20 Núm. 1 (2009); 120-127Revista de Investigaciones Veterinarias del Perú; Vol. 20 No. 1 (2009); 120-1271682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/571/467Derechos de autor 2009 Andrea Flores M., Hermelinda Rivera G., César Gavidia Ch.https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/5712020-03-16T17:49:24Z
