[Blue eye disease virus inoculation in Mexican Hairless boars] | Inoculacion del virus de la enfermedad del ojo azul en verracos de la raza Pelon Mexicano

Inglés. Five Mexican Hairless boars were inoculated with Blue Eye Disease Rubulavirus in order to study clinical signs and pathologic findings in this breed. After inoculation by both intranasal and intramuscular routes clinical signs were observed in each boar daily. Subsequently, animals were slaugthered at 5, 10, 20, 30 and 45 days after inoculation. Samples were taken from tonsils, liver, lung, spleen, kidneys, mediastinic nodules, brain, testicles, epididimus, prostate, Cowper gland and seminal vesicles for histopathology and viral isolation. Clinical signs were evident after 15 days postinoculation. Corneal opacity and testicle edematization were observed 7 days after inoculation. The epididimus head presentes granulomatous nodules at 20, 30 and 45 days post-infection. Some samples for viral isolation were positive at 5, 10, 20, 30 and 45 days

Español; castellano. Se inocularon cinco cerdos adultos de la raza Pelon Mexicano con el rubulavirus porcino que causa la enfermedad del ojo azul, sacrificandolos a los 5, 10, 20, 30 y 45 dias posinoculacion para observar la secuencia semiotica y el tipo de las lesiones en cada una de ellos. Al momento de la necropsia se obtuvieron muestras de tonsilas, pulmon, higado, bazo, rinon, nodulo linfatico mediastinico, cerebro, testiculo, epididimo, prostata, vesicula seminal y glandula bulbouretral, con el fin de aislar al virus y determinar el momento en que se detectaba su presencia (el cultivo celular PK 15). La manifestacion durante signos solo ocurrio en los primeros quince dias posinoculacion. La opacidad de la cornea se presento al septimo dia. La edematizacion del testiculo izquierdo se observo entre el quinto y el decimo dias. La cabeza de los epididimos mostraron nodulos granulomatosos a los 20, 30 y 45 dias posinoculacion. Se pudo recuperar el virus de diferentes tejidos durante todo el periodo experimental
