High levels of unreported intraspecific diversity among RNA viruses in faeces of neonatal piglets with diarrhoea
(BMC, 2019-12-05)
BACKGROUND:
Diarrhoea is a major cause of death in neonate pigs and most of the viruses that cause it are RNA viruses. Next Generation Sequencing (NGS) deeply characterize the genetic diversity among ...
Analysis of the genetic diversity and mRNA expression level in porcine reproductive and respiratory syndrome virus vaccinated pigs that developed short or long viremias after challenge
(BioMed Central, 2018-02-15)
Porcine reproductive and respiratory syndrome virus (PRRSv) infection alters the host’s cellular and humoral immune
response. Immunity against PRRSv is multigenic and vary between individuals. The aim ...
The use of a whole inactivated PRRS virus vaccine administered in sows and impact on maternally derived immunity and timing of PRRS virus infection in piglets
(Wiley, 2022-04-05)
Background: Porcine reproductive and respiratory syndrome virus (PRRSV) vaccination is usually based on administering periodically PRRS modified live virus (MLV) in sows throughout their life. Using ...
Diversity of influenza A viruses retrieved from respiratory disease outbreaks and subclinically infected herds in Spain (2017-2019)
(Wiley, 2020-07-03)
The present study was aimed to assess the diversity of influenza A viruses (IAV) circulating in pig farms in the Iberian Peninsula. The study included two different situations: farms suffering respiratory ...
Bottlenecks in the transmission of porcine reproductive and respiratory syndrome virus (PRRSV1) to naïve pigs and the quasi-species variation of the virus during infection in vaccinated pigs
(BMC, 2018-10-19)
This paper describes the results of two experiments regarding porcine reproductive and respiratory syndrome virus (PRRSV1): the first one studied the existence of bottlenecks in an experimental one-to-one ...
The immune response does not prevent homologous Porcine epidemic diarrhoea virus reinfection five months after the initial challenge
(Wiley, 2021-03-04)
The aim of the present study was to evaluate the duration of protective immunity against Porcine epidemic diarrhoea virus (PEDV). To do so, a two phases study was performed. In the first phase, 75 ...
