Prevalence of linguatulosis in cattle (Bos taurus) in a slaughtering house of Chile

Descripción del Articulo

The objective of the present study was to determine the prevalence of linguatulosis in bovine viscera in a slaughter house in Curicó, VII Region, Chile. The macroscopic examination of the liver, lungs, heart and the mediastinal, mesenteric and hepatic lymph nodes of 269 cattle was performed. In case...

The macroscopic examination of the liver, lungs, heart and the mediastinal, mesenteric and hepatic lymph nodes of 269 cattle was performed. In cases of lesions compatible with linguatulosis, the viscera were considered positive and these were observed under a stereoscope to reach the etiological diagnosis, considering as positive the lesions that presented one or more nymphs. The results showed that 11.89% of the cattle presented lesions compatible with linguatulosis in the viscera analysed and only one (0.37%) presented the positive etiological diagnosis of Linguatula serrata nymphs. The largest number of compatible lesions was found in the liver (81.8%), followed by mesenteric lymph nodes (9.1%), hepatic lymph nodes (6.1%) and lungs (3.0%). No lesions were detected in the heart and mediastinal lymph nodes. There is no validated method to identify macroscopic lesions caused by linguatulosis, so the finding of compatible lesions can be biased since these could be caused by other agents. Linguatulosis is non-notifiable disease in Chile, despite being considered as a zoonotic disease and having importance in public health.El objetivo del presente estudio fue determinar la prevalencia de linguatulosis en vísceras de bovinos beneficiados en una planta faenadora de la ciudad de Curicó, VII Región, Chile. Se realizó el examen macroscópico del hígado, pulmones, corazón y de los linfonodos mediastinales, mesentéricos y hepáticos de 269 bovinos. En los casos de lesiones compatibles con linguatulosis, la víscera se consideró positiva y estas fueron observadas bajo estereoscopio para llegar al diagnóstico etiológico, considerando como positivo las que presentaron una o más ninfas. El 11.89% de los bovinos presentaron lesiones compatibles con linguatulosis en las vísceras analizadas y solo uno (0.37%) presentó el diagnóstico etiológico positivo con presencia de ninfa de Linguatula serrata. La mayor cantidad de lesiones compatibles se encontraron en el hígado (81.8%), seguido en linfonodos mesentéricos (9.1%), linfonodos hepáticos (6.1%) y pulmón (3.0%). No se detectaron lesiones en corazón y linfonodos mediastinales. No existe un método validado para identificar lesiones macroscópicas causadas por la linguatulosis, de modo que el hallazgo de lesiones compatibles puede causar sesgos, ya que estas podrían ser causadas por otros agentes. La linguatulosis no es una enfermedad de notificación obligatoria en Chile, a pesar de considerarse como una enfermedad zoonótica y tener importancia en salud pública.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2019-07-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/1607710.15381/rivep.v30i2.16077Revista de Investigaciones Veterinarias del Perú; Vol 30 No 2 (2019); 856-863Revista de Investigaciones Veterinarias del Perú; Vol. 30 Núm. 2 (2019); 856-8631682-34191609-9117reponame:Revista UNMSM - Revista de Investigaciones Veterinarias del Perúinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/16077/14087Derechos de autor 2019 Juan José Ramos G., Pamela Morales M., Hortensia Carmona H., Alex Silva G.http://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2021-06-01T18:09:52Zmail@mail.com -
