Welfare Benefits of Intradermal Vaccination of Piglets
(MDPI, 2020-10-16)
Vaccination is reported as a stressful and painful event for animals. This study investigated whether needle-free intradermal vaccination improves the welfare of weaned pigs through the reduction of ...
Protection provided by a commercial modified-live porcine reproductive and respiratory syndrome virus (PRRSV) 1 vaccine (PRRSV1-MLV) against a Japanese PRRSV2 field strain
(Korean Society of Veterinary Science, 2023-07-07)
Background: Porcine reproductive and respiratory syndrome virus (PRRSV) vaccines do not provide full cross-protection, mainly due to the virus genetic variability. Despite this, vaccines based on ...
Rules of thumb to obtain, isolate, and preserve porcine peripheral blood mononuclear cells
(Elsevier, 2022-07-16)
One of the most used biospecimens in immunology are peripheral blood mononuclear cells (PBMC). PBMC are particularly useful when evaluating immunity through responses of circulating B- and T-cells, ...
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 ...
