DETECTION OF PORCINE CIRCOVIRUS 3 IN PIGS AFFECTED BY DIFFERENT DISEASES AND PATHOLOGICAL CONDITIONS

Porcine circovirus 3 (PCV3) is a novel species of circovirus detected in several countries around the world during the last two years. PCV3 has been found in several tissue samples or sera from pigs with different clinical presentations, as well as in healthy animals. The present study aimed to assess whether PCV3 was present in sera of pigs suffering from different pathological conditions as well as its coexistence with other pathogens.

INFECTION DYNAMICS OF PORCINE CIRCOVIRUS 3 IN LONGITUDINALLY SAMPLED PIGS FROM A SPANISH FARM

Porcine circovirus 3 (PCV3) is an emerging circovirus species that has recently been reported in different countries around the world, suggesting a widespread circulation. Previous studies related the presence of this virus in pigs with different clinical manifestations, as well in healthy animals and a higher prevalence in nursery piglets. The objective of this study was to assess the infection dynamics of PCV3 in a commercial farm from Spain.

RETROSPECTIVE DETECTION OF PORCINE CIRCOVIRUS 3 IN PIG SERUM SAMPLES FROM SPAIN

A new Circovirus species able to infect domestic pigs has been recently described and named Porcine circovirus 3 (PCV3). This virus was initially found in 2016 in the USA and subsequently in Asia, Europe and South America in 2017. The goal of this study was to perform a retrospective study to detect evidence of PCV3 infection in serum samples of pigs collected in the last two decades from Spain.

BIOSECURITY AND VACCINATION AS EFFECTIVE TOOLS TO HANDLE AN PRRSV OUTBREAK

This report describes a case where higher number of stillbirths, weak piglets and therapy-resistant piglet diarrhoea occurred in a sow herd. In the affiliated barn for weaned pigs, an increasing number of animals showed diarrhoea and respiratory disease.

PRRSV CONTROL AND SOW PLANER EVALUATION ON THREE DIFFERENT SOW FARMS

After a variety of clinical diseases occurred in three different sow farms in Germany, investigations were undertaken to identify the cause of disease. The farmers reported an increase in stillbirths, late abortions, sows returning to oestrus and piglet mortality with diarrhoea.

PRRSV SUCCESSFULLY HANDLED WITH WHOLE HERD VACCINATION. CONCEPT AND BIOSAFETY ANALYSIS

Five farmers supplied by one piglet breeder increasingly complained of disease-susceptible and poorer-growing pigs and therefore an increased need for antibiotic treatment. The piglet breeding facility is a 2 side production system with 480 sows, located in lower Saxony, Germany. The weaned pigs are kept in outdoor climate barns, 1.5 km away from the sows.

AN AUTOMATED CLASSIFICATION SYSTEM FOR PRRS ORF5 SEQUENCES

A classification system based on PRRS ORF5 sequences would be useful to assess progress in control program and for surveillance purposes. The objective of this study was to evaluate the feasibility of an automated system that could be used for very large datasets and would consistently give reliable results over time.

SURVEILLANCE OF PRRS VIRUS STRAINS-HOW NEW TOOLS CAN SUPPORT CONTROL INITIATIVES

PRRS sequencing (ORF5) is widely used in Quebec, Canada. Through several signed agreements with veterinarians, a structure was established allowing near real-time transfer of sequences to our research team from 3 different laboratories in Quebec. As a result, our database has grown to nearly 6000 sequences, with an annual averaged increase of 450 sequences. This database has allowed the development of several tools that can be used for surveillance.

CORRELATION BETWEEN SERUM POOLS, ORAL FLUID AND FECAL SOCK SAMPLES FOR PCV2 QUANTIFICATION IN A DANISH FINISHER HERD

Porcine circovirus type 2 (PCV2) is often quantified by qPCR from pooled serum samples or penwise oral fluid samples (OF). PCV2 can also be detected in feces. The objectives of the study were to compare PCV2 viral loads in pooled serum samples, OF and FS collected in the same pens and to assess the impact of individual pig´s viral load on a pooled serum sample.

THE EFFECT OF POOLING TWO DIFFERENT TYPES OF SAMPLES TO DETECT TYPE 1 PRRS VIRUS ON PRE-WEANING PIGLETS IN AN ENDEMIC POSITIVE HERD AND PRACTICAL IMPLICATIONS

Most of the time, breeding herd stability against PRRSv is assessed by sampling 30 due-to-wean piglets in a farrowing batch and pooling the samples by five to test them with a RT-qPCR test. The aim of this study was to compare the capacity to detect PRRSv in pre-weaning piglets using 2 different types of samples per litter and pooling them by five.

CHARACTERIZATION OF PRRS VIRUS AND EPIDEMIOLOGICAL ASPECTS IN SWINE FARMS IN COSTA RICA

The Porcine Reproductive and Respiratory Syndrome (PRRS) was firstly recognized clinically in the EU in 1987 and spreaded through Europe and America. This virus has two genotypes: with type 1 predominating in Europe and type 2 in North America and Asia. The aim of this study was to identify and to characterize the PRRS virus circulating and to estimate the prevalence in pig farms in Costa Rica.

PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS DETECTION IN WEANINGAGE PIGLETS IN 120 FRENCH FARMS

To assess the stability of a sow herd against Porcine Reproductive and Respiratory Syndrome virus (PRRSv), PCR on blood in weaning-age piglets is regularly implemented. This work describes the results obtained in 120 farms.

PCV2GENOTYPES : EPIDEMIOLOGICAL SURVEY IN THE WEST OF FRANCE

Since 2004 a worldwide shift of porcine circovirus type 2 (PCV2) genotypes was observed from PCV2a towards PCV2b and more recently PCV2d (since 2012).

FIRST DETECTION OF PORCINE PARVOVIRUS 7 IN POLAND

In the last years several novel parvoviruses (PPV) were discovered in pigs worldwide. The most recently discovered porcine parvovirus species is PPV7, which was reported in USA and China to date. The aim of the study was to present the first evidence of PPV7 in Polish pigs

PRRSV TYPE 1 TRANSMISSION VIA PIGLET TRAILERS – RELEVANCE FOR SPREADING?

A field study was performed in Germany to evaluate the role of transport vehicles as a source of transmission of porcine reproductive and respiratory syndrome virus (PRRSV) to susceptible pigs. Risk factors for transmission of PRRSV type 2 via transport vehicles has been described, while little is known about PRRSV type 1 transmission via trucks in Europe.
