Impact of maternally derived immunity on immune responses elicited by piglet early vaccination against the most common pathogens involved in porcine respiratory disease complex
(BMC, 2022-03-16)
Background
Newborn piglets can trigger an elementary immune response, but the acquirement of specific antibodies and/or cellular immunity against pathogens before they get infected post-natally is ...
Frequency of Detection and Phylogenetic Analysis of Porcine circovirus 3 (PCV-3) in Healthy Primiparous and Multiparous Sows and Their Mummified Fetuses and Stillborn
(MDPI, 2020-07-02)
Porcine circovirus 3 (PCV-3) has been suggested as a putative causal agent of swine reproductive disease. A number of different studies have pointed out this association, but there is still a lack of ...
Sow Vaccination with a Protein Fragment against Virulent Glaesserella (Haemophilus) parasuis Modulates Immunity Traits in Their Offspring
(MDPI, 2021-05-20)
Glaesserella (Haemophilus) parasuis, an early colonizer of the nasal cavity in piglets, is a highly heterogeneous species, comprising both commensal and virulent strains. Virulent G. parasuis strains ...
Porcine Circovirus 3 Detection in Aborted Fetuses and Stillborn Piglets from Swine Reproductive Failure Cases
(MDPI, 2021-02-09)
Porcine circovirus 3 (PCV-3) has been widely detected in healthy and diseased pigs; among different pathologic conditions, the strongest evidence of association comes from reproductive disease cases. ...
Experimental Inoculation of Porcine Circovirus 3 (PCV-3) in Pregnant Gilts Causes PCV-3-Associated Lesions in Newborn Piglets that Persist until Weaning
(Wiley, 2023-10-20)
Porcine circovirus 3 (PCV-3) has been detected in cases of reproductive failure but the pathogenesis of such infection is poorly
understood. So far, experimental PCV-3 inoculations have been performed ...
Descriptive analyses of maternally-derived antibody levels against porcine circovirus 2 (PCV-2) in 3-and 21-day-old piglets from farms of four European countries using different vaccination protocols in sows
(BMC, 2022-10-03)
Background
Up to now, information on the levels of maternally-derived antibodies (MDA) against PCV-2 in suckling piglets born to sows vaccinated with different strategies is scarce in the literature. ...
Current knowledge on Porcine circovirus 3 (PCV-3): A novel virus with a yet unknown impact on the swine industry
(Frontiers Media, 2018-12-12)
Porcine circovirus 3 (PCV-3) is a recently described virus belonging to the family Circoviridae. It represents the third member of genus Circovirus able to infect swine, together with PCV-1, considered ...
Lack of Porcine circovirus 4 Genome Detection in Pig Samples from Italy and Spain
(MDPI, 2020-05-31)
The genus Circovirus includes several species and mostly causes asymptomatic infections. Porcine circovirus 2 (PCV-2) and, with increasing evidence, Porcine circovirus 3 (PCV-3), have been associated ...
Detection of Porcine Circovirus 3 in Wildlife Species in Spain
(MDPI, 2020-05-01)
Porcine circovirus 3 (PCV-3) is the third member of the family Circoviridae, genus Circovirus, able to infect swine. A high prevalence of viral DNA has been recorded in wild boars. Recently, PCV-3 DNA ...
Infection dynamics of porcine circovirus type 3 in longitudinally sampled pigs from four Spanish farms
(BMJ Publishing Group, 2019-04-30)
Porcine circovirus type 3 (PCV-3) is a recently discovered virus in domestic pigs and wild boar. The virus has been described in pigs with different clinical/pathological presentations and healthy ...
