| description |
Cuando se hace referencia a la hepatitis viral del pato (HVP), se está hablando, de una infección de curso agudo que, además, es extremadamente contagiosa en patos cuyo tiempo de vida es de menos de 6 semanas de edad y, con frecuencia, en patos de menos de 3 semanas, esta suele estar clasificada en los tipos I, II y III. La HVP de tipo I puede desencadenarse por al menos tres genotipos distintos del virus de la hepatitis A del pato (VHPA), siendo estos un miembro del género Avihepatovirus, de la familia Picornaviridae. El más patógeno y diseminado es el VHPA de tipo I (VHPA-1), que en un principio se denominaba virus de la hepatitis del pato-1. Los virus VHPA-2 y VHPA-3 son dos genotipos del género Avihepatovirus que posteriormente han sido identificados como agentes etiológicos adicionales del VHP en los patos. Al ser observada como una enfermedad clínica, esta es caracterizada por un proceso de letargo y ataxia, seguidos de opistótonos y teniendo como desenlace la muerte del pato. Es probable, bajo otras circunstancias, que se presenten cuestiones como la esplenomegalia y tumefacción renal con cierta congestión de los vasos sanguíneos renales. Por otro lado, también se deben destacar todas aquellas lesiones microscópicas del hígado, que van desde la necrosis hepatocitaria extensa, hasta la hiperplasia del conducto biliar, junto con ciertos grados de variables de respuesta inflamatoria y hemorrágica. En Colombia, la enfermedad fue reportada por primera vez en 1984 en aves provenientes de la costa norte del país y fue declarada oficialmente ante la OIE en el año 2001. Ésta se reportó en lotes de pollos de engorde entre las 5 y 10 semanas de edad generando un cuadro clínico caracterizado por tener un curso rápido (24 horas o incluso menos) y una mortalidad acumulativa entre 3,7 y 6%, dando un tiempo limitado para actuar contra el virus. Es necesario realizar estudios que determinen la presencia de anticuerpos contra adenovirus tipo I y hepatitis con cuerpos de inclusión en granjas, con el objetivo de aportar al conocimiento del comportamiento de este agente etiológico que afecta las explotaciones avícolas del país. El presente trabajo pretende recopilar información actualizada al respecto de la hepatitis viral del pato y singular frecuencia de presentación en territorio Colombiano durante su ruta Migratoria. |

Type I DVH can be triggered by at least three different genotypes of duck hepatitis A virus (DHAV), being a member of the genus Avihepatovirus, family Picornaviridae. The most pathogenic and widespread is the type I HPAV (HPAV-1), which was originally called duck hepatitis virus-1. VHPA-2 and VHPA-3 are two genotypes of the genus Avihepatovirus that have subsequently been identified as additional aetiological agents of VHP in ducks. When observed as a clinical disease, it is characterised by a process of lethargy and ataxia, followed by opisthotonos and leading to death of the duck. Under other circumstances, issues such as splenomegaly and renal swelling with some congestion of the renal blood vessels are likely to occur. On the other hand, microscopic lesions of the liver, ranging from extensive hepatocyte necrosis to bile duct hyperplasia, along with varying degrees of inflammatory response and haemorrhage, should also be noted. In Colombia, the disease was first reported in 1984 in birds from the northern coast of the country and was officially declared to the OIE in 2001. It was reported in broiler flocks between 5 and 10 weeks of age, generating a clinical picture characterised by a rapid course (24 hours or even less) and a cumulative mortality between 3.7 and 6%, giving a limited time to act against the virus. So far, there are no reports on the prevalence of the disease in Colombia. Based on the above, it is necessary to carry out studies to determine the presence of antibodies against adenovirus type I and hepatitis with inclusion bodies in farms, with the aim of contributing to the knowledge of the behaviour of this aetiological agent that affects poultry farms in the country. It is also important to promote research in the departments of Cundinamarca and Santander, where there is a high concentration of commercial poultry, in order to promote the control and prevention of the virus to avoid diseases of economic impact on the Colombian poultry industry. The objective aims to compile updated information on viral hepatitis in ducks and its singular frequency of presentation in Colombian territory during its migratory route.tannia.galindom@campusucc.edu.conicolas.aragona@campusucc.edu.co34 p.Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, IbaguéMedicina veterinaria y zootecniaIbaguéHepatitis viralPatoEnfermedadInfecciónMigraciónColombiaTG 2021 MVZ 34786Viral hepatitisDuckDiseaseInfectionMigrationColombiaHepatitis viral del pato y su presentación en el ánade real o azulón (ánade platyrhynchos), en el territorio colombiano durante su ruta migratoriaTrabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1finfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionAtribucióninfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Guo WN, Zhu B, Ai L, Yang DL, Wang BJ.
