Identificación de bovinos persistentemente infectados y genotipo del virus de la diarrea viral en bovinos de Anta, Cusco, Perú

Abstract: El objetivo del presente estudio fue identificar bovinos persistentemente infectados (PI) y el genotipo del virus de la diarrea viral (VDVB) en bovinos de pequeños ganaderos de cinco distritos de la provincia de Anta, Cusco, que resultaron negativos a anticuerpos contra el VDVB (n=558) en un estudio previo. La identificación de los animales PI se realizó en las 558 muestras de suero de bovinos Holstein, Brown Swiss y criollos hembras de varias edades, mediante la prueba de ELISA de captura. La identificación d… Show more

“…On the other hand, although BVDV presented the lowest animal seroprevalence (21.7%), its high prevalence at the farm level (94.6%) generates a worrying health indicator due to its particular difficulty in control and eradication, and its important contribution to respiratory and reproductive problems (VARGAS et al, 2009). The difficulty in control and eradication is associated with the existence of persistently infected animals that while living are important reservoirs and transmitters of BVDV (VARgAS et al, 2009;VAlDEZ et al, 2018). In Peru, a study in cattle determined a 50% seroprevalence to BVDV and a 2.2% prevalence of persistently infected animals in the population that was seronegative (VALDEZ et al, 2018).…”

“…In Italy, Nogarol et al (2017) con rmed the presence of ve PI animals carrying a BVDV-2a strain. Valdez et al (2018) described PI animals with BVDV-1 in Peru, and Barbosa et al (2019) detected BVDV-1a in Colombia. In a case-control study conducted by Kadohira and Tajima (2010) in Japan, 41 PI cows were detected in 23 different farms between 2006 and 2007, without subgenotype determination.…”
