Using commercial ELISAs to assess humoral response in sows repeatedly vaccinated with modified live porcine reproductive and respiratory syndrome virus
(BMJ Publishing Group, 2019-10-01)
Background Sows in breeding herds are often mass vaccinated against porcine reproductive and respiratory syndrome (PRRS) every few months using modified live vaccines (MLV). Field veterinarians repeatedly ...
Impact of Cryopreservation on Viability, Phenotype, and Functionality of Porcine PBMC
(Frontiers Media, 2021-11-29)
The use of frozen peripheral blood mononuclear cells (PBMC) is common in immunological studies. The impact of freezing PBMC has been assessed using human and mice cells, but little information is available ...
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 ...
Immune response development after vaccination of 1-day-old naïve pigs with a Porcine Reproductive and Respiratory Syndrome 1-based modified live virus vaccine
(BMC, 2019-02-02)
Background
The development of the innate and adaptive immune responses to Porcine reproductive and respiratory syndrome virus (PRRSV) after vaccination of 1 day-old pigs with a PRRSV-1 based modified ...
Development of pig conventional dendritic cells from bone marrow hematopoietic cells in vitro
(Frontiers Media, 2020-10-08)
In recent years, porcine dendritic cells (DCs) have been identified from pig tissues. However, studying the interaction of porcine DCs with pathogens is still difficult due to the scarcity of DCs in ...
Diversity of respiratory viruses present in nasal swabs under influenza suspicion in respiratory disease cases of weaned pigs
(Frontiers Media, 2022-10-19)
Respiratory diseases in weaned pigs are a common problem, with a complex etiology involving both viruses and bacteria. In the present study, we investigated the presence of eleven viruses in nasal swabs, ...
Systemic CD4 cytotoxic T cells improve protection against PRRSV-1 transplacental infection
(Frontiers Media, 2023-01-17)
Background: Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the major swine pathogens causing reproductive failure in sows. Although modified-live virus (MLV) vaccines are available, ...
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 ...
Characterization of homologous and heterologous adaptive immune responses in porcine reproductive and respiratory syndrome virus infection
(BMC, 2012-04-19)
The present study characterized the homologous and heterologous immune response in type-I porcine
reproductive and respiratory syndrome virus (PRRSV) infection. Two experiments were conducted: in ...
