Prolonged detection of PCV2 and anti-PCV2 antibody in oral fluids following experimental inoculation.

Transboundary and emerging diseases, 2016
The onset, level and duration of PCV2 and anti-PCV2 antibody in oral fluid were evaluated using samples collected from experimentally inoculated pigs for 98 days post-inoculation (DPI). Pigs (n = 24) were obtained at 3 weeks of age and randomly allocated to 4 treatment pens of 6 pigs each: (i) negative control group; (ii) inoculated with PCV2a (strain ...

Vorkommen von Genotypen des porzinen Circovirus Typ 2 (PCV2) in Schweinebeständen mit unterschied lichen Impfstrategien gegen PCV2

Tierärztliche Praxis Ausgabe G: Großtiere / Nutztiere, 2017
ZusammenfassungZiel: Seit den Jahren 2004/2005 zeigt sich beim porzinen Circovirus (PCV2) weltweit eine Veränderung der Nachweisrate vom Genotyp PCV2a zu PCV2b. Da alle kommerziell verfügbaren Impfstoffe auf dem Genotyp PCV2a basieren, hatte die Studie das Ziel, das Vorkommen von PCV2a und PCV2b in Beständen mit unterschiedlichen Impfstrategien gegen ...

PCV2 Replicase Transcripts in Infected Porcine Kidney (PK15) Cells

Virus Genes, 2002
The Circoviridae family includes small viruses containing circular single strand DNA. There are two circoviruses described in pigs. Porcine Circovirus 2 (PCV2) has been linked to a disease termed Postweaning Multisystemic Wasting Syndrome (PMWS) whereas a close relative of this virus, termed PCV type 1 (PCV1) has been considered a non-pathogenic ...

Ear necrosis reduction in pigs after vaccination against PCV2

Research in Veterinary Science, 2011
The influence of sows vaccination against PCV2 on the prevalence of ear necrosis syndrome (ENS) reduction among weaners was analyzed using 12,931 piglets from 45 consecutive batches, born to both, vaccinated and non-vaccinated sows. The results were statistically tested with a nonparametric Kruskal-Wallis and Chi-square tests.

SEROLOGICAL STATUS OF PCV2-INFECTED SWINE HERDS

2023
This study aimed to determine the dynamics of serological and virological profiles against Porcine Circovirus type 2 (PCV2) infection in Thai swine herds using the in-house indirect ELISA and real-time PCR techniques. A total of 10 swine herds in Thailand were divided into two groups according to their clinical history. Group A (n=5) had clinical signs

Immune response to PCV2 vaccination in PRRSV viraemic piglets

Veterinary Record, 2016
PORCINE circovirus type 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) are the two most important pathogens currently responsible for major economic losses to the swine industry worldwide. PCV2 vaccines are extensively used and are able to reduce the clinical signs of PCV2-associated disease.

Intestinal mucosal PCV2-specific immune response in PCV2 vaccinated and non-vaccinated conventional gilts.

2013
Oro-fecal contamination is of utmost importance in the epidemiology of PCV2 and intestinal immune-competent cells play an important role for the systemic immune response in pigs. From a previous experiment three parts of the intestinal tract (duodenum, jejunum, ileum) of conventional gilts, vaccinated (V) or not (NV) against PCV2 and experimentally ...

PCV2 shedding after challenge by infected semen in PCV2 vaccinated and non-vaccinated conventional gilts.

2012
Porcine circovirus type 2 (PCV2) is endemic in swine herds and both viremia and shedding are demonstrated in newborn as well as in adult pigs. The reduction of PCV2 circulation is a protective strategy to be attained by several direct and indirect prophylactic measures.

[Occurrence of genotypes of porcine circovirus (PCV2) in pig farms using different vaccination strategies against PCV2].

Tierarztliche Praxis. Ausgabe G, Grosstiere/Nutztiere, 2017
Since 2004/2005 a worldwide shift of the detection rate of porcine circovirus (PCV) has been observed from PCV2a towards PCV2b. Currently commercially available vaccines are based on genotype PCV2a. The study was conducted as a pilot study to evaluate the occurrence of PCV2a and PCV2b in farms with different vaccination strategies against PCV2.For this
